This symbol is used in safety instructions to remind not to rub non-metallic surfaces with a dry cloth; ensure the cloth is damp. It is used in safety instructions where non-compliance in the hazardous area would cause the risk of an explosion.

This sign is not a safety symbol but indicates an important instruction in the assembly process.

1.6.2 Personnel qualification and training

All personnel involved in the operation, installation, inspection and maintenance of the unit must be qualified to carry out the work involved. If the personnel in question do not already possess the necessary knowledge and skill, appropriate training and instruction must be provided. If required, the operator may commission the manufacturer/supplier to provide applicable training.

Always coordinate repair activity with operations and health and safety personnel. Follow all plant safety requirements and applicable safety and health laws and regulations.

1.6.3 Safety action

This is a summary of conditions and actions to help prevent injury to personnel and damage to the environment and to equipment. For products used in potentially explosive atmospheres section 1.6.4 also applies.

U-

MAG™ pumps contain extremely strong permanent neodymium magnets which could affect the functioning of pacemakers and implanted heart defibrillators. If you wear these devices keep sufficient distance to magnets.

Magnets produce a far-reaching, strong magnetic field. They can damage laptops, computer hard drives, credit and ATM cards, data storage media, mechanical watches, hearing aids and speakers. Keep magnets away from devices and objects that could be damaged by strong magnetic fields.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER

GUARDS MUST NOT BE REMOVED WHILE

THE PUMP IS OPERATIONAL

DRAIN THE PUMP AND ISOLATE PIPEWORK

BEFORE DISMANTLING THE PUMP

The appropriate safety precautions should be taken where the pumped liquids are hazardous.

NEVER use heat (risk of explosion) to disassemble any portion of the pump.

HIGH TEMPERATURES may be present.

Pump surface temperature is directly related to the temperature of the working fluid. Never operate pump above the rated temperature of 121°C (250°F).

Page 5 of 40

U-MAG ENGLISH 26999990 10-14

HANDLING COMPONENTS

Many precision parts have sharp corners and the wearing of appropriate safety gloves and equipment is required when handling these components. To lift heavy pieces above 25 kg (55 lb.) use a crane appropriate for the mass and in accordance with current local regulations.

Personal Protection Equipment suitable for the conditions and environment must be worn at all times.

THERMAL SHOCK

Rapid changes in the temperature of the liquid within the pump can cause thermal shock, which can result in damage or breakage of components and should be avoided.

HOT (and cold) PARTS

If hot or freezing components or auxiliary heating supplies can present a danger to operators and persons entering the immediate area action must be taken to avoid accidental contact. If complete protection is not possible, the machine access must be limited to maintenance staff only, with clear visual warnings and indicators to those entering the immediate area.

If the temperature is greater than 80 ºC (175 ºF) or below -5 ºC (23 ºF) in a restricted zone, or exceeds local regulations, action as above shall be taken.

HAZARDOUS LIQUIDS

When the pump is handling hazardous liquids care must be taken to avoid exposure to the liquid by appropriate siting of the pump, limiting personnel access and by operator training. If the liquid is flammable and or explosive, strict safety procedures must be applied.

PREVENT EXCESSIVE EXTERNAL

PIPE LOAD. Do not use pump as a support for piping.

Do not mount expansion joints, unless allowed by

Flowserve in writing, so that their force, due to internal pressure, acts on the pump flange.

Never loosen flange connection while system is under pressure.

Always make certain pressure gages, indicating lights and safety devices are working.

NEVER RUN THE PUMP DRY. Use diamond-like-coated (DLC) parts for additional protection from dry running. DLC does not guarantee dry run protection.

Never start this pump without proper prime

(casing must be full of liquid).

START THE PUMP WITH THE

DISCHARGE VALVE PARTLY OPENED (Unless otherwise instructed at a specific point in the User

Instructions.) This is recommended to minimize the risk of overloading and damaging the pump or motor at full or zero flow. Pumps may be started with the valve further open only on installations where this situation cannot occur. The pump outlet control valve may need to be adjusted to comply with the duty following the runup process. (See section 5, Commissioning start-up,

operation and shutdown.)

SUCTION VALVES TO BE FULLY OPEN WHEN

PUMP IS RUNNING

Running the pump at zero flow or below the recommended minimum flow continuously will cause damage to the pump. Never operate this pump with the suction and / or discharge valve closed as this may lead to high surface temperatures.

The direction of rotation is clockwise when viewed from the motor end. Rotation of the motor must be checked prior to starting the pump according to section 5.1.

DO NOT RUN THE PUMP AT

ABNORMALLY HIGH OR LOW FLOW RATES

Operating at a flow rate higher than normal or at a flow rate with no back pressure on the pump may overload the motor and cause cavitation. Low flow rates may cause a reduction in pump/bearing life, overheating of the pump, instability and cavitation/vibration.

NEVER EXCEED THE MAXIMUM

DESIGN PRESSURE (MDP) AT THE TEMPERATURE

SHOWN ON THE PUMP NAMEPLATE AND

INCLUDED IN SECTION 3.5.2.

Driver may overload and de-couple if pumpage specific gravity is greater than originally assumed. Prolonged running while de-coupled will damage driver and impeller magnets.

ALWAYS know the EMERGENCY STOP location for the pump.

Decoupling the pump may lead to increased surface temperatures.

Page 6 of 40

U-MAG ENGLISH 26999990 10-14

Never change conditions of service without approval of authorized Flowserve distributor.

Excessive amounts of dust collected on the pump housing may lead to an increase in surface temperature, possibly exceeding temperature limits.

May require regular cleaning.

Always have this service manual available during any installation or maintenance.

1.6.4 Products used in potentially explosive atmospheres

Measures are required to:

Avoid excess temperature

Prevent build up of explosive mixtures

Prevent the generation of sparks

Prevent leakages

Maintain the pump to avoid hazard

The following instructions for pumps and pump units when installed in potentially explosive atmospheres must be followed to help ensure explosion protection.

For ATEX, both electrical and non-electrical equipment must meet the requirements of European Directive

2014/34/EU (previously 94/9/EC which remains valid until April 20 th

2016 during the transition). Always observe the regional legal Ex requirements eg Ex electrical items outside the EU may be required certified to other than ATEX eg IECEx, UL.

1.6.4.1 Scope of compliance

Use equipment only in the zone for which it is appropriate. Always check that the driver and pump equipment are suitably rated and/or certified for the classification of the specific atmosphere in which they are to be installed.

Where Flowserve has supplied only the bare shaft pump, the Ex rating applies only to the pump. The party responsible for assembling the ATEX pump set shall select the coupling, driver and any additional equipment, with the necessary CE Certificate/

Declaration of Conformity establishing it is suitable for the area in which it is to be installed.

The output from a variable frequency drive (VFD) can cause additional heating effects in the motor and so, for pumps sets with a VFD, the ATEX Certification for the motor must state that it is covers the situation where electrical supply is from the VFD. This particular requirement still applies even if the VFD is in a safe area.

1.6.4.2 Marking

An example of ATEX equipment marking is shown below. The actual classification of the pump will be engraved on the nameplate.

ENSURE THE EQUIPMENT TEMPERATURE

CLASS IS SUITABLE FOR THE HAZARD ZONE

Pumps have a temperature class as stated in the

ATEX Ex rating on the nameplate. These are based on a maximum ambient of 40 ºC (104 ºF); refer to

Flowserve for higher ambient temperatures.

The surface temperature on the pump is influenced by the temperature of the liquid handled. The maximum permissible liquid temperature depends on the ATEX temperature class and must not exceed the values in the table that follows.

* The table only takes the ATEX temperature class into consideration. Pump design or material, as well as component design or material, may further limit the maximum working temperature of the liquid.

Page 7 of 40

U-MAG ENGLISH 26999990 10-14

The temperature rise at the bearings and due to the minimum permitted flow rate is taken into account in the temperatures stated.

The operator is responsible to ensure that the specified maximum liquid temperature is not exceeded.

Temperature classification “Tx” is used when the liquid temperature varies and when the pump is required to be used in differently classified potentially explosive atmospheres. In this case the user is responsible for ensuring that the pump surface temperature does not exceed that permitted in its actual installed location.

Avoid mechanical, hydraulic or electrical overload by using motor overload trips, temperature monitors and/or a power monitor and make routine vibration monitoring checks.

In dirty or dusty environments, make regular checks and remove dirt from areas around close clearances, bearing housings and motors.

Where there is any risk of the pump being run against a closed valve generating high liquid and casing external surface temperatures fit an external surface temperature protection device.

1.6.4.4 Preventing the build-up of explosive mixtures

ENSURE THE PUMP IS PROPERLY FILLED

AND DOES NOT RUN DRY

Ensure the pump and relevant suction and discharge pipeline system is totally filled with liquid at all times during the pump operation, so that an explosive atmosphere is prevented.

If the operation of the system cannot avoid this condition, fit an appropriate dry run protection device

(for example liquid detection or a power monitor).

To avoid potential hazards from fugitive emissions of vapor or gas to atmosphere the surrounding area must be well ventilated.

1.6.4.5 Preventing sparks

To avoid the potential hazard from random induced current generating a spark, the baseplate must be properly grounded.

Avoid electrostatic charge: do not rub non-metallic surfaces with a dry cloth ; ensure cloth is damp.

Additional requirement for metallic pumps on

non-metallic baseplates

When metallic components are fitted on a nonmetallic baseplate they must be individually earthed.

If so equipped, to prevent a potential hazard from mechanical contact, the coupling guard must be nonsparking. For ATEX the coupling must be selected to comply with European Directive 2014/34/EU

(previously 94/9/EC which remains valid until April

20 th

2016 during the transition). Correct coupling alignment must be maintained.

1.6.4.6 Preventing leakage

The pump must only be used to handle liquids for which it has been approved to have the correct corrosion resistance.

Avoid entrapment of liquid in the pump and associated piping due to closing of suction and discharge valves, which could cause dangerous excessive pressures to occur if there is heat input to the liquid. This can occur if the pump is stationary or running.

Bursting of liquid containing parts due to freezing must be avoided by draining or protecting the pump and ancillary systems.

If leakage of liquid to atmosphere can result in a hazard, install a liquid detection device or secondary containment.

1.6.4.7 Maintenance to avoid the hazard

CORRECT MAINTENANCE IS REQUIRED TO

AVOID POTENTIAL HAZARDS WHICH GIVE A

RISK OF EXPLOSION

The responsibility for compliance with maintenance instructions is with the plant operator.

To avoid potential explosion hazards during maintenance, the tools, cleaning and painting materials used must not give rise to sparking or adversely affect the ambient conditions. Where there is a risk from such tools or materials, maintenance must be conducted in a safe area.

It is recommended that a maintenance plan and schedule is adopted. (See section 6, Maintenance.)

1.7.2 Safety labels

1.8 Specific machine performance

For performance parameters see section 1.5, Duty

conditions. Where performance data has been supplied separately to the purchaser these should be obtained and retained with these User Instructions.

1.9 Noise level

Attention must be given to the exposure of personnel to the noise, and local legislation will define when guidance to personnel on noise limitation is required, and when noise exposure reduction is mandatory.

This is typically 80 to 85 dBA. The usual approach is to control the exposure time to the noise or to enclose the machine to reduce emitted sound.

You may have already specified a limiting noise level when the equipment was ordered, however if no noise requirements were defined, then attention is drawn to the following table to give an indication of equipment noise level so that you can take the appropriate action in your plant.

Pump noise level is dependent on a number of operational factors, flow rate, pipework design and acoustic characteristics of the building, and so the values given are subject to a 3 dBA tolerance and cannot be guaranteed.

Similarly the motor noise provided in the table below is

“pump and motor” noise that is typically expected from standard and high efficiency motors when on load directly driving the pump. Note that a motor driven by an inverter may show an increased noise at some speeds.

If a pump unit only has been purchased for fitting with your own driver, then the noise levels in the table should be adjusted for the driver level obtained from the supplier. Consult Flowserve or a noise specialist if assistance is required in adjusting the values.

It is recommended that where exposure approaches the prescribed limit, then site noise measurements should be made

.

The values are in sound pressure level L pA at 1 m (3.3 ft) from the machine, for “free fiel d conditions over a reflecting plane”.

720 rpm reduce 1450 rpm values by 3 dBA. (3.) Choosing a fancooled motor will increase noise levels. (4.) Placing valves, orifices, or flow meters near a pump will increase noise levels inside the pump.

For estimating sound power level L

(re 1 pW) then add 14 dBA to the sound pressure value.

2 TRANSPORT AND STORAGE

2.1 Consignment receipt and unpacking

Immediately after receipt of the equipment it must be checked against the delivery/shipping documents for

Page 9 of 40

U-MAG ENGLISH 26999990 10-14

its completeness and that there has been no damage in transportation. Any shortage and/or damage must be reported immediately to Flowserve and must be received in writing within one month of receipt of the equipment. Later claims cannot be accepted.

Check any crate, boxes or wrappings for any accessories or spare parts that may be packed separately with the equipment or attached to side walls of the box or equipment.

Each pump/wet end has a unique serial number.

Check that this number corresponds with that advised. Always use this number in correspondence and when ordering spare parts or further accessories.

2.2 Handling

Boxes, crates, pallets or cartons may be unloaded using fork lift vehicles or slings dependent on their size and construction.

2.3 Lifting

A crane must be used for all pump sets or components in excess of 25 kg (55 lb.). Fully trained personnel must carry out lifting, in accordance with local regulations. Slings, ropes and other lifting gear should be positioned where they cannot slip and where a balanced lift is obtained. The angle between sling or ropes used for lifting must not exceed 60°.

To avoid distortion, the pump unit should be lifted as shown.

Pumps and motors often have integral lifting lugs or eye bolts. These are intended for use in only lifting the individual piece of equipment.

Do not use eye bolts or cast-in lifting lugs to lift pump, motor and baseplate assemblies.

Care must be taken to lift components or assemblies above the center of gravity to prevent the unit from flipping.

2.3.1 Lifting Wet-End

The wet end should be lifted by sling around the pump discharge nozzle using a choker hitch pulled tight as shown in Figure 2-1.

Figure 2-1

2.3.2 Lifting pump and motor assembly

For pump and motor, sling around the pump discharge nozzle, and around the outboard end of the motor frame using choker hitches pulled tight. The sling should be positioned so the weight is not carried through the motor fan housing. (Figure 2-2)

Figure 2-2

2.3.3 Lifting pump, motor and baseplate assembly

If the baseplate has lifting holes cut in the sides at the end (Type D, Type E bases and Type A when provided) insert lifting S hooks at the four corners and use slings or chains to connect to the lifting eye. Do not use slings through the lifting holes.

For other baseplates, sling around the pump discharge nozzle, and around the outboard end of the motor frame using choker hitches pulled tight. The sling should be positioned so the weight is not carried through the motor fan housing. (Figure 2-3)

Assembled units and their components are heavy. Failure to properly lift and support this equipment can result in serious physical injury and/or equipment damage. Lift equipment only at the specifically identified lifting points. Lifting devices such as eyebolts, slings, and spreaders must be rated, selected, and used for the entire load being lifted.

Crush hazard. The unit and the components can be heavy. Use proper lifting methods and wear steeltoed shoes at all times.

Do not attach sling ropes to shaft ends.

Make sure that the unit cannot roll or fall over and injure people or damage property.

These pumps use carbon or ceramic silicon carbide components. Do not drop the pump or subject it to shock loads as this can damage the internal ceramic components.

2.4 Storage

Store the pump in a clean, dry location away from vibration. Leave piping connection covers in place to keep dirt and other foreign material out of pump casing.

The pump may be stored as above for up to 6 months. Consult Flowserve for preservative actions when a longer storage period is needed.

2.5 Recycling and end of product life

At the end of the service life of the product or its parts, the relevant materials and parts should be recycled or disposed of using an environmentally acceptable method and local requirements. If the product contains substances that are harmful to the environment, these should be removed and disposed of in accordance with current regulations.

Make sure that hazardous substances are disposed of safely and that the correct personal protective equipment is used. The safety specifications must be in accordance with the current regulations at all times.

3.4 Design of major parts

3.4.1 Pump casing

Ductile iron armor with bonded ETFE lining.

The U-

MAG™ pump casing is designed with a horizontal centerline end inlet and a top outlet.

For ease of maintenance, the pump is constructed so that pipe connectors do not have to be disturbed when internal maintenance is required (back pull out).

3.4.2 Impeller

Integrally molded one-piece impeller / inner rotor. The impeller is fully shrouded (closed) with fully open suction, and the inner rotor is fitted with Neodymium

Iron Boron (NdFeB) magnets.

3.4.3 Wetted Bearings System

The standard material for the bearing is carbon and the shaft is alpha sintered silicon carbide (SiC). The system is comprised of a shaft which is cantilever mounted into the containment shell and a rotating bushing mounted in the impeller. The impell er’s wear ring is carbon as standard and runs against the casing thrust collar, which is SiC.

3.4.4 Containment Ring

One-piece ductile iron part aligns and supports the containment shell to establish the pressure boundary of the pump. Allows servicing of the motor without opening the liquid end of the pump.

3.4.5 Outer Magnet Assembly

One-piece ductile iron housing fitted with Neodymium

Iron Boron (NdFeB) magnets. One common outer rotor for each motor frame and a visual alignment groove allows for ease of axial alignment.

3.4.6 Containment Shell and O-Ring

The containment shell is comprised of an aramid fiber composite outer housing and an ETFE liner. The shell includes a fully confined O-ring groove which establishes the gasket interface with the casing.

3.4.7 Adapter

Mates pump to motor. Design allows the use of multiple motors with one adapter.

3.4.8 Driver

The driver is normally an electric motor. Different drive configurations may be fitted such as internal combustion engines, turbines, hydraulic motors, and driving via couplings, belts, gearboxes, drive shafts, etc.

3.4.9 Accessories

Accessories may be fitted when specified by the customer

3.5 Performance and operating limits

This product has been selected to meet the specifications of the purchase order. See section 1.5.

The following data is included as additional information to help with your installation. It is typical, and factors such as temperature and materials may influence this data. If required, a definitive statement for your particular application can be obtained from

Flowserve.

3.5.1 Operating limits

Normal maximum ambient temperature:

+40 ºC (104 ºF).

Normal minimum ambient temperature:

-20 ºC (-4 ºF).

Maximum pump speed: refer to the nameplate.

3.5.2 Pressure-Temperature Rating

The pump pressure and temperature limits are included in the Figure 3-2. The standard U-MAG

TM casing has a universal, slotted flange bolt pattern which accommodates ANSI, ISO, and JIS piping flange standards. Optional drilling arrangements include ANSI Class 150, ISO PN 16, and JIS 10K.

Find the maximum allowable pressure for the supplied pump, given the flange drilling pattern and operating temperature.

The maximum discharge pressure must be less than or equal to the P-T rating. Discharge pressure may be approximated by adding the suction pressure to the differential pressure developed by the pump.

3.5.3 Energy Efficiency Operation of Pumps

The pump supplied will have been selected from

Flowser ve’s extensive product line to have optimum efficiency for the application. If supplied with an electric motor then the motor will meet or exceed current legislation for motor efficiency. However it is the way the pump is operated which has the greatest impact on the amount and cost of energy used during the operating life of the pump. The following are key points in achieving minimum operating cost for the equipment: a) Design the pipe system for minimum friction losses b) Ensure that the control system switches off the pump when not required c) In a multi-pump system run the minimum number of pumps d) Try to avoid systems which by-pass excess flow e) Avoid as far as possible controlling pump flow by throttle valves f) When commissioned, check that the pump operates at the duty specified to Flowserve g) If it has been found that the pump head and flow exceed that required, trim the pump impeller diameter h) Ensure that the pump is operating with sufficient

NPSH available. i) Use variable speed drives for systems which require variable flow. A VFD for an induction motor is a particularly effective way of achieving speed variation and energy/cost reduction j) Notes for VFD usage a) make sure that the motor is compatible with VFD b) Do not over-speed the pump without checking the power capability with

Flowserve c) On systems with high static head, speed reduction is limited. Avoid running the pump at a speed which gives low or zero flow d) Do not run at a low speed and flow rate which lets solid settle out of suspension in the pipe work e) Do not use a VFD for a fixed flow requirement; it will introduce power losses k) Select high efficiency motors l) If replacing a standard motor with a high efficiency motor it will run faster and the pump could take more power. Reduce the impeller diameter to achieve energy reduction m) If the pump system pipe work or equipment is changed or process duty is changed, check that the pump is still correctly sized n) Periodically check that the pipe system has not become corroded or blocked o) Periodically check that the pump is operating at the flow, head and power expected and that the efficiency has not reduced with erosion or corrosion damage.

4 INSTALLATION

Equipment operated in hazardous locations must comply with the relevant explosion protection regulations. See section 1.6.4, Products used in

potentially explosive atmospheres.

4.1 Location

The pump should be located to allow room for access, ventilation, maintenance and inspection with ample headroom for lifting and should be as close as practicable to the supply of liquid to be pumped. Refer to the general arrangement drawing for the pump set.

4.2 Part Assemblies

The supply of motors and baseplates are optional.

As a result, it is the responsibility of the installer to ensure that the motor is assembled to the pump and aligned as detailed in section 4.5 and 4.8.

Page 14 of 40

U-MAG ENGLISH 26999990 10-14

4.3 Foundation

A pump should be located near the supply of liquid and have adequate space for operation, maintenance, and inspection. Baseplate mounted pumps are normally placed on a concrete foundation, which has been poured on a solid footing.

The foundation must be able to absorb any vibration and to form a permanent, rigid support for the pumping unit. a) Prepare site - Inspect foundation for dirt, oil, chips, water, etc. and remove any contaminants. b) Install mounting bolts using hole pattern determined by baseplate size. Sleeve-type and Jtype bolts are commonly used to allow movement for final bolt adjustment. Follow best company standards and practices.

4.3.1 Protection of openings and threads

When the pump is shipped, all openings are covered.

This protection/covering should not be removed until installation. If, for any reason, the pump is removed from service, this protection should be reinstalled.

4.3.2 Rigid baseplates - overview

The function of a baseplate is to provide a rigid foundation under a pump and its driver that maintains alignment between the two. Baseplates may be generally classified into two types:

Foundation-mounted, grouted design (Figure 4-1)

Stilt mounted, or free standing. (Figure 4-2.)

Figure 4-1

Figure 4-2

Baseplates intended for grouted installation are designed to use the grout as a stiffening member.

Stilt mounted baseplates, on the other hand, are designed to provide their own rigidity. Therefore the designs of the two baseplates are usually different.

Regardless of the type of baseplate used, it must provide certain functions that ensure a reliable installation. Three of these requirements are:

The baseplate must provide sufficient rigidity to assure the assembly can be transported and installed, given reasonable care in handling, without damage. It must also be rigid enough when properly installed to resist operating loads.

The baseplate must provide a reasonably flat mounting surface for the pump and driver.

Uneven surfaces will result in a soft-foot condition. Experience indicates that a baseplate with a top surface flatness of 1.25 mm/m (0.015 in./ft) across the diagonal corners of the baseplate provides such a mounting surface.

Therefore, this is the tolerance to which we supply our standard baseplate. Some users may desire an even flatter surface, which can facilitate installation and alignment. Flowserve will supply flatter baseplates upon request at extra cost. For example, mounting surface flatness of 0.17 mm/m (0.002 in./ft) is offered on the Flowserve

Type E “Ten Point” baseplate in Figure 4-1.

The baseplate must be designed to allow the user to final field align the pump and driver to within their own particular standards and to compensate for any pump or driver movement that occurred during handling. U-MAG

TM

pumps have a close-coupled configuration only and alignment is achieved by the mating of precisionmachined surfaces. See section 4.8 for more information.

4.3.3 Stilt and spring mounted baseplates

Flowserve offers stilt and spring mounted baseplates.

(See Figure 4-2 for stilt mounted option.) The low vibration levels of U-

MAG™ pumps allow the use of these baseplates - provided they are of a rigid design.

The baseplate is set on a flat surface with no tie down bolts or other means of anchoring it to the floor.

General instructions for assembling these baseplates are given below. For dimensional information, please refer to the appropriate Flowserve “Sales print.”

4.3.3.1 Stilt mounted baseplate assembly instructions

Refer to Figure 4-3. a) Raise or block up baseplate/pump above the floor to allow for the assembly of the stilts. b) Predetermine or measure the approximate desired height for the baseplate above the floor. c) Set the bottom nuts [2] above the stilt bolt head

[1] to the desired height. d) Assemble lock washer [3] down over the stilt bolt.

Page 15 of 40

U-MAG ENGLISH 26999990 10-14

e) Assemble the stilt bolt up through hole in the bottom plate and hold in place. f) Assemble the lock washer [3] and nut [2] on the stilt bolt. Tighten the nut down on the lock washer. g) After all four stilts have been assembled, position the baseplate in place, over the floor cups [4] under each stilt location, and lower the baseplate to the floor. h) Level and make final height adjustments to the suction and discharge pipe by first loosening the top nuts and turning the bottom nuts to raise or lower the baseplate. i) Tighten the top and bottom nuts at the lock washer [3] first then tighten the other nuts. j) It should be noted that the connecting pipelines must be individually supported, and that the stilt mounted baseplate is not intended to support total static pipe load.

Figure 4-3

h) After all four stilts have been assembled, position the baseplate in place, over the floor cups [7] under each stilt location, and lower the baseplate down to the floor. i) Level and make final height adjustments to the suction and discharge pipe by first loosening the top nuts, and turning the bottom nuts to raise or lower the baseplate. j) Recompress the top spring to the compression established in step g, and lock the nuts in place. k) It should be noted that the connecting pipelines must be individually supported, and that the spring mounted baseplate is not intended to support total static pipe loads.

Figure 4-4

4.3.3.2 Stilt/spring mounted baseplate assembly instructions

Refer to Figure 4-4. a) Raise or block up baseplate/pump above the floor to allow for the assembly of the stilts. b) Set the bottom nuts [4] above the stilt bolt head

[1]. This allows for 51 mm (2 in.) upward movement for the final height adjustment of the suction/discharge flange. c) Assemble the lock washer [6] flat washer [5] and bottom spring/cup assembly [2] down over the stilt bolt [1]. d) Assemble the stilt bolt/bottom spring up through hole in the bottom plate and hold in place. e) Assemble top spring/cup assembly [3] down over stilt bolt. f) Assemble flat washer [5], lock washer [6] and nuts [4] on the stilt bolt. g) Tighten down top nuts, compressing the top spring approximately 13 mm (0.5 in.). Additional compression may be required to stabilize the baseplate.

The remaining steps are as listed for new grouted baseplates.

4.4 Grouting

Where applicable, grout in the foundation bolts.

Foundation bolts should only be fully tightened when the grout has cured.

After adding pipework connections and rechecking the pump alignment, the baseplate should then be grouted in accordance with good engineering practice.

Fabricated steel, folded steel and cast iron baseplates can be filled with grout. Polycrete baseplates cannot be grouted in the same way, see their User Instructions

71569284 (E) for installation and use. If in any doubt, please contact your nearest service center for advice.

Grouting provides solid contact between the pump unit and foundation prevents lateral movement of vibrating equipment and dampens resonant vibrations.

4.4.1 Baseplate Inspection

a) Completely clean the underside of baseplate.

Page 16 of 40

U-MAG ENGLISH 26999990 10-14

b) Inspect for any damage that would impede proper installation or future use of the baseplate. c) Confirm baseplate hole pattern for proper mounting bolt installation. d) Lower the baseplate carefully onto mounting bolts. Caution: Must adhere to proper transport and lifting procedures. e) Level the baseplate using shims and/or wedges.

Use machinist’s levels to maintain a flat and level surface. f) Max difference across length 3.2 mm (0.125 in.) g) Max difference across width 1.5 mm (0.059 in.) h) Secure baseplate using mounting bolts to prevent unwanted movement during operation. Torque bolts to appropriate company standards and practices. i) Perform final inspection to verify that baseplate is securely mounted, level, and ready to be used.

4.5 Piping

Protective covers are fitted to both the suction and discharge flanges of the casing and must be removed prior to connecting the pump to any pipes.

4.5.1 Suction and discharge piping

Never use pump as a support for piping.

Ensure piping and fittings are flushed before use.

Ensure piping for hazardous liquids is arranged to allow pump flushing before removal of the pump.

Take into account the available NPSH which must be higher than the required NPSH of the pump.

All piping must be independently supported, accurately aligned and preferably connected to the pump by a short length of flexible piping. The pump should not have to support the weight of the pipe or compensate for misalignment. It should be possible to install suction and discharge bolts through mating flanges without pulling or prying either of the flanges. All piping must be tight. Pumps may air-bind if air is allowed to leak into the piping. If the pump flange(s) have tapped holes, select flange fasteners with thread engagement at least equal to the fastener diameter but that do not bottom out in the tapped holes before the joint is tight.

The following is the recommended procedure for attaching piping to the U-

MAG™ pump (see section 6.5 for torque values)

Check the surface of both flanges (pump/pipe) to ensure they are clean, flat, and without defects

Lubricate the fasteners

Hand tighten all of the fasteners in a crisscross pattern

The fasteners should be torqued in increments

– based a crisscross pattern

See torque chart in Section 6.5 o The first increment should be 75% of full torque o The second increment should be at the full torque o Verify that the torque value of the 1 st

fastener is still at the full torque value. Re-torque all fasteners after 24 hours or after the first thermal cycle.

Re-torque all fasteners at least annually

4.5.2 Suction piping

To avoid NPSH and suction problems, suction piping must be at least as large as the pump suction connection. Never use pipe or fittings on the suction that are smaller in diameter than the pump suction size.

Figure 4-5 illustrates the ideal piping configuration with a minimum of 10 pipe diameters between the source and the pump suction. In most cases, horizontal reducers should be eccentric and mounted with the flat side up as shown in Figure 4-6 with a maximum of one pipe size reduction. Never mount eccentric reducers with the flat side down.

Horizontally mounted concentric reducers should not be used if there is any possibility of entrained air in the process fluid. Vertically mounted concentric reducers are acceptable. In applications where the fluid is completely de-aerated and free of any vapour or suspended solids, concentric reducers are preferable to eccentric reducers.

Figure 4-5 Figure 4-6

Page 17 of 40

U-MAG ENGLISH 26999990 10-14

Avoid the use of throttling valves and strainers in the suction line. Start-up strainers must be removed shortly before start up. When the pump is installed below the source of supply, a valve should be installed in the suction line to isolate the pump and permit pump inspection and maintenance. However, never place a valve directly on the suction nozzle of the pump.

Refer to the Centrifugal Pump IOM Section of the H.I.

Standards for additional recommendations on suction piping. (See section 10.)

Refer to section 3.4 for performance and operating limits.

4.5.3 Discharge piping

Install a valve in the discharge line. This valve is required for regulating flow and/or to isolate the pump for inspection and maintenance.

When fluid velocity in the pipe is high, for example, 3 m/s (10 ft/sec) or higher, a rapidly closing discharge valve can cause a damaging pressure surge. A dampening arrangement should be provided in the piping.

4.5.4 Allowable nozzle loads

Maximum forces and moments allowed on the pump flanges vary with the pump size and type. To minimize these forces and moments that may, if excessive, cause misalignment, hot bearings, worn couplings, vibration and the possible failure of the pump casing, the following points should be strictly followed:

Prevent excessive external pipe load

Never draw piping into place by applying force to pump flange connections

Do not mount expansion joints so that their force, due to internal pressure, acts on the pump flange

Contact your local Flowserve Sales office, Distributor, or Representative for further details.

4.5.5 Auxiliary piping

The connections that are to be piped up will have been fitted with protective metal or plastic plugs which will need to be removed.

4.6 Electrical connections

Electrical connections must be made by a qualified Electrician in accordance with relevant local national and international regulations.

It is important to be aware of the EUROPEAN

DIRECTIVE on potentially explosive areas where compliance with IEC60079-14 is an additional requirement for making electrical connections.

It is important to be aware of the EUROPEAN

DIRECTIVE on electromagnetic compatibility when wiring up and installing equipment on site. Attention must be paid to ensure that the techniques used during wiring/installation do not increase electromagnetic emissions or decrease the electromagnetic immunity of the equipment, wiring or any connected devices. If you have any doubt contact Flowserve for advice.

The motor must be wired up in accordance with the motor manufacturer's instructions (normally supplied within the terminal box) including any temperature, earth leakage, current and other protective devices as appropriate.

The identification nameplate should be checked to ensure the power supply is appropriate.

A device to provide emergency stopping must be fitted. If not supplied pre-wired to the pump unit, the controller/starter electrical details will also be supplied within the controller/starter. For electrical details on pump sets with controllers see the separate wiring diagram.

See section 5.1, Direction of rotation before connecting the motor to the electrical supply.

For close coupled pumps it is necessary to wire the motor with flexible conduit of sufficient length to allow the motor/power end assembly to be moved back from the casing [1100] for maintenance.

4.7 Protection systems

The following protection systems are recommended particularly if the pump is installed in a potentially explosive area or is handling a hazardous liquid. If in any doubt consult Flowserve.

If there is any possibility of the system allowing the pump to run against a closed valve or below minimum continuous safe flow a protection device should be installed to ensure the temperature of the liquid does not rise to an unsafe level.

Page 18 of 40

U-MAG ENGLISH 26999990 10-14

If there are any circumstances in which the system can allow the pump to run dry, or start up empty, a power monitor should be fitted to stop the pump or prevent it from being started. This is particularly relevant if the pump is handling a flammable liquid.

If leakage of product from the pump or its associated sealing system can cause a hazard it is recommended that an appropriate leakage detection system is installed.

To prevent excessive surface temperatures at bearings it is recommended that temperature or vibration monitoring is carried out.

4.7.1 Auxiliary equipment

– instrumentation

Contact your local Flowserve Sales office, Distributor, or Representative for more details.

4.7.1.1 Leak detection

An intrinsically-safe, optical leak detection system is available for U-

MAG™ pumps.

4.7.1.2 Temperature probe

An optional ThermicSense temperature probe can be installed on the casing drain to monitor the internal fluid in the casing [1100].

4.7.1.3 ThermicSense Installation

The ThermicSense thermowell will be packaged separately for protection during shipping and must be assembled before use. For wiring refer to the thermocouple sensor manufacturer’s instructions a) Verify that rubber gasket / o-ring is secured to temperature sensor tip. b) Insert temperature sensor tip into the thermowell and hand tighten. c) Use a 1/2 in. wrench to fully secure the sensor to the thermowell.

Do not over-tighten. d) Adjust direction of sensor sheathing before tightening compression fitting. e) Ensure sensor tip is fully pressed into thermowell.

The sensor must be fully inserted to get an accurate reading. f) Hand-tighten the compression fitting. g) Use a 1/2 in. wrench to fully tighten the compression fitting and secure sensor sheathing.

Do not over tighten the fitting. h) Affix the PTFE drain gasket to thermal well. i) Insert the completed ThermicSense assembly into the casing drain and insert 1/2 in.-13 bolts with lock washers. j) Tighten bolts evenly to maintain alignment and torque to 13.5 Nm (10 lbf

•ft) k) Install wire leads to appropriate temperature monitor per manufacturer instructions and guidelines.

4.8 Final checks

Alignment between the pump shaft and motor shaft is built in by precise machining of the parts that position these shafts. Parallel alignment of 0.18 mm (0.007 in.) and angular alignment of 0.002 mm/mm (0.002 in./in.) can be expected.

Check the tightness of all bolts in the suction and discharge pipework. Check also the tightness of all foundation bolts.

5 COMMISSIONING, START-UP,

OPERATION AND SHUTDOWN

These operations must be carried

out by fully trained and qualified personnel.

Personal Protection Equipment suitable for the conditions and environment must be worn at all times.

5.1 Direction of rotation

Correct rotation is indicated by the arrow on the casing [1100]. Improper rotation will not damage the pump however, performance is greatly reduced. Rotation may be determined by viewing the motor’s fan.

Do not bump the motor to test rotation or run the pump without the suction completely flooded.

Dry running can damage the pump in a matter of seconds if the pump is not equipped with dry-run bearings.

If maintenance work has been carried out to the site's electricity supply, the direction of rotation should be re-checked in case the supply phasing has been altered.

5.2 Priming and auxiliary supplies

5.2.1 Auxiliary supplies

Ensure all electrical, hydraulic, pneumatic, sealant and lubrication systems (as applicable) are connected and operational.

5.2.2 Filling and priming

Ensure inlet pipe and pump casing

[1100] is completely full of liquid before starting continuous duty operation.

Priming may be carried out with an ejector, vacuum pump, interceptor or other equipment, or by flooding from the inlet source.

When in service, pumps using inlet pipes with foot valves may be primed by passing liquid back from the outlet pipe through the pump.

5.3 Starting the pump

a) CLOSE the discharge valve.

Fully open the suction valve. Pump requires a flooded suction. b) Do not operate pump with suction valve closed. Operating pump more than a few minutes after suction valve closed may cause bearing failure. c) Fully open discharge valve to complete priming.

Turn back the discharge valve until it is 1/4 to 1/2 open. d) Continuous operation against a closed discharge valve may cause pump to overheat. e) Start motor and check the outlet pressure. f) If the pressure is satisfactory, SLOWLY open the outlet valve. g) Do not run the pump with the outlet valve closed for a period longer than 10 seconds. h) If NO pressure, or LOW pressure, STOP the pump. Refer to section 7, Troubleshooting, for fault diagnosis.

5.4 Running the pump

Care must be taken when operating pump.

Safety gloves are essential. Loose clothing must not be worn.

5.4.1 Normal vibration levels, alarm and trip

For guidance, pumps generally fall under a classification for rigid support machines within the International rotating machinery standards and the recommended maximum levels are based on those standards.

Alarm and trip values for installed pumps should be based on the actual measurements taken on the pump in the fully commissioned as new condition. Measuring vibration at regular intervals will then show any deterioration in pump or system operating conditions.

5.6 Hydraulic, mechanical and electrical duty

This product has been supplied to meet the performance specifications of your purchase order, however it is understood that during the life of the product these may change. The following notes may help the user decide how to evaluate the implications of any change. If in doubt contact your nearest Flowserve office.

5.6.1 Specific gravity (SG)

Pump capacity and total head in metres (feet) do not change with SG, however pressure displayed on a pressure gauge is directly proportional to SG. Power absorbed is also directly proportional to SG. It is therefore important to check that any change in SG will not overload the pump driver or over-pressurize the pump.

5.6.2 Viscosity

For a given flow rate the total head reduces with increased viscosity and increases with reduced viscosity. Also for a given flow rate the power absorbed increases with increased viscosity, and reduces with reduced viscosity. It is important that checks are made with your nearest Flowserve office if changes in viscosity are planned.

5.6.3 Pump speed

Changing pump speed effects flow, total head, power consumed, NPSH

R

, noise and vibration. Flow varies in direct proportion to pump speed, head varies as speed ratio squared and power varies as speed ratio cubed. The new duty, however, will also be dependent on the system curve. If increasing the speed, it is important therefore to ensure the maximum pump working pressure is not exceeded, the driver is not overloaded, NPSH

A

> NPSH

R

, and that noise and vibration are within local requirements and regulations.

5.6.4 Net positive suction head (NPSH

A

)

NPSH available (NPSH

A

) is a measure of the head available in the pumped liquid, above its vapour pressure, at the pump suction branch.

NPSH required (NPSH

R

) is a measure of the head required in the pumped liquid, above its vapour pressure, to prevent the pump from cavitating. It is important that NPSH

A

> NPSH

R

. The margin between

NPSH

A

> NPSH

R

should be as large as possible.

If any change in NPSH

A

is proposed, ensure these margins are not significantly eroded. Refer to the pump performance curve to determine exact requirements particularly if flow has changed.

If in doubt please consult your nearest Flowserve office for advice and details of the minimum allowable margin for your application.

5.6.5 Pumped flow

Flow must not fall outside the minimum and maximum continuous safe flow shown on the pump performance curve and or data sheet.

6 MAINTENANCE

6.1 General

It is the plant operator's responsibility to ensure that all maintenance, inspection and assembly work is carried out by authorized and qualified personnel who have adequately familiarized themselves with the subject matter by studying this manual in detail.

(See also section 1.6.2.)

Personal Protection Equipment suitable for the conditions and environment must be worn at all times.

Any work on the machine must be performed when it is at a standstill. It is imperative that the procedure for shutting down the machine is followed

On completion of work all guards and safety devices must be re-installed and made operative again.

Before restarting the machine, the relevant instructions listed in section 5, Commissioning, start

up, operation and shut down must be observed.

Oil and grease leaks may make the ground slippery. Machine maintenance must always begin and finish by cleaning the ground and the exterior of the machine.

If platforms, stairs and guard rails are required for maintenance, they must be placed for easy access to areas where maintenance and inspection are to be carried out. The positioning of these accessories must not limit access or hinder the lifting of the part to be serviced.

When air or compressed inert gas is used in the maintenance process, the operator and anyone in the vicinity must be careful and have the appropriate protection.

Do not spray air or compressed inert gas on skin.

Do not direct an air or gas jet towards other people.

Page 21 of 40

U-MAG ENGLISH 26999990 10-14

Never use air or compressed inert gas to clean clothes.

Before working on the pump, take measures to prevent an uncontrolled start. Put a warning board on the starting device with the words:

"Machine under repair: do not start".

With electric drive equipment, lock the main switch open and withdraw any fuses. Put a warning board on the fuse box or main switch with the words:

"Machine under repair: do not connect".

Never clean equipment with flammable solvents or carbon tetrachloride. Protect yourself against toxic fumes when using cleaning agents.

When operating with CHARGABLE LIQUIDS with conductivities of <10-8 S/m, inert gases (e.g. nitrogen) must be used to flush the pump. Before removal of the pump it is recommended to wait one hour to allow static peak charges to be eliminated.

ALWAYS make certain that no toxic or flammable fumes / vapors remain in the pump casing

[1100] or surrounding area.

6.2 Maintenance schedule

It is recommended that a maintenance plan and schedule is adopted, in line with these User

Instructions, to include the following: a) Any auxiliary systems installed must be monitored, if necessary, to ensure they function correctly. b) Check for any leaks. Pump is designed to be leak-free, any leak is abnormal. c) Check that the duty condition is in the safe operating range for the pump. d) Check vibration, noise level and surface temperature to confirm satisfactory operation. e) Check dirt and dust is removed from areas around close clearances and motors.

Our specialist service personnel can help with preventative maintenance records and provide condition monitoring for temperature and vibration to identify the onset of potential problems.

If any problems are found the following sequence of actions should take place: a) Refer to section 7, Troubleshooting, for fault diagnosis. b) Ensure equipment complies with the recommendations in this manual. c) Contact Flowserve if the problem persists.

6.2.1 Preventive Maintenance Guidelines

Different applications call for different preventative maintenance schedules. Applications that involve pumping abrasives, or applications that are likely to precipitate solids should be examined on a regular basis to ensure that accumulating solids (if any) are removed. There are many factors that can necessitate periodic preventative maintenance and inspection, but for clean, continuously operating services, preventative maintenance can usually be done without disassembling the pump. See recommended spare parts list for more information.

Devices/techniques to help monitor the pump externally: a) Install pressure gauges on the suction and discharge b) Regularly monitor the process conditions c)

Use the motor’s fan to check for free rotation d) Use a shaft power monitor to protect the pump as well as monitor pump performance e) Check vibration, noise level and surface temperature to confirm satisfactory operation.

For preventative maintenance schedule recommendations that are specific to your application, please contact your authorized local distributor.

If ABRASIVE SOLIDS are present within the fluid, additional wear of the pump should be expected.

Intervals between inspections should be shortened compared to usual times.

6.2.2 Routine inspection (daily/weekly)

The following checks should be made and the appropriate action taken to remedy any deviations: a) Check operating behaviour. Ensure noise, vibration and bearing temperatures are normal. b) Check that there is no abnormal fluid leak from the pump. c) Check any auxiliary equipment or supplies are functioning correctly.

Refer to the manuals of any associated equipment for routine checks needed.

Page 22 of 40

U-MAG ENGLISH 26999990 10-14

6.2.3 Periodic inspection (six monthly)

a) Check foundation bolts for security of attachment and corrosion.

Refer to the manuals of any associated equipment for periodic checks needed.

6.3 Spare parts

6.3.1 Ordering of spares

6.6 Disassembly

The preventative maintenance and disassembly procedures are intended for use during standard field inspection or service. The disassembly can take place while the pump is piped up or in a maintenance shop. If at all possible, it is recommended to perform all repairs using the shop procedures to reduce the risk of damage to the SiC parts.

Lock out driver power to prevent accidental start-up that could result in serious personal injury.

Lock out and/or disconnect power.

Shut off all valves controlling flow to and from the pump. Isolate the pump from the system and relive any remaining system pressure.

Refer to Safety section before dismantling the pump.

Before dismantling the pump for overhaul, ensure genuine Flowserve INNOMAG® replacement parts are available.

Refer to sectional drawings for part numbers and identification. (See section 8, Parts lists and drawings.)

When operating with chargeable liquids with conductivities of <10-8 S/m, inert gases (e.g. nitrogen) must be used to flush the pump. Before removal of the pump it is recommended to wait one hour to allow static peak charges to be eliminated.

When handling hazardous and/or toxic fluids, skin, eye and respiratory protection are required.

If pump is being drained, precautions must be taken to prevent injury or environmental contamination.

6.6.1 Drive / Wet End Separation

Flowserve INNOMAG® pumps contain extremely strong magnets. The use of non-magnetic tools and work surface is highly recommended. The work area must be clean and free of any ferrous particles.

Wet end and drive end separation requires significant care. The magnetic coupling between the impeller [2200] and outer drive [0230] magnets is very strong. This process requires the magnetic field between the outer drive and impeller to be broken.
