PRECAUTIONS

WHEN LIQUID BEING PUMPED IS

HAZARDOUS OR VOLATILE, ALWAYS

TAKE FULL PRECAUTIONS. THIS

INCLUDES THE RUN-IN PERIOD AND

DURING DISASSEMBLY AND ASSEMBLY

OF PUMP.

Controls, guards, walkways, machine arrangement, crew training, etc., are all necessary factors in the creation of a safe, practical installation and are generally not a part of our services. It is the responsibility of the contractor, installer, owner, and user to add to the materials furnished by Roper Pump

Company to result in a safe installation and to comply with OSHA, state and local laws, and

the ANSI/NFPA Life Safety Code.

There are many kinds of devices for pumps and systems such that if one component in a system is stopped, other equipment feeding or following it also can be automatically stopped.

Serious thought should be given to the installation of these types of devices in every pump system.

• DO NOT attempt to install, operate, or perform maintenance on this equipment without first reading and understanding the material in this manual. Also, read and understand all tags and any other documentation accompanying the pump.

• DO NOT operate this equipment in excess of its rated capacity, pressure, speed, and temperature, or other than according to the instructions contained in this manual.

• DO NOT continue to operate this equipment if there is a failure of any part of the equipment or system. Correct the failure before operating the equipment.

• DO NOT bypass safety controls or guards.

Their purpose is to protect and they must be in proper working order.

• DO NOT operate equipment without proper guards in place.

• DO NOT walk, stand, sit, or lean on guards.

• DO NOT work on a pump while it is operating or if there is a chance of the driver becoming energized except to adjust the relief valve.

• DO NOT adjust packing while the pump is operating or if there is a chance of the driver becoming energized.

• DO NOT adjust the integral relief valve without coupling guards in place.

• DO NOT place hands, feet, head, or any other part of your body in any pump opening while the pump can be operated.

• DO NOT poke or prod material in the pump.

• DO NOT start to disassemble the pump if there is the slightest chance of it becoming energized by accident. Lock out the energy source to the driver and disconnect the coupling before performing maintenance to the equipment.

• DO NOT wear loose or dangling clothing or jewelry near the equipment. It could become caught and possibly cause serious injury or death.

• DO NOT use metallic or hard faced striking tools when the need for tapping parts into position arises. Hard faced striking tools may damage parts or they may fracture or chip and send particles flying that could cause possible injury.

• DO NOT allow spills to remain in the work area. Clean up spills immediately. Oils, greases, and other fluids used in the equipment may create hazards if not cleaned up immediately after a spill.

• DO NOT spin bearings with compressed air. This is highly dangerous and can cause the bearing to fragment with explosive force, possibly causing serious injury or death.

• DO NOT attempt to install, use, or repair this equipment while under the influence of any substance that may impair physical or mental abilities. This includes, but is not limited to, alcohol and prescription and nonprescription drugs.

Page 2 – 2

• DO NOT dispose of fluoroelastomers by burning. Toxic vapors are released by this compound upon combustion.

• DO NOT suspend pumps from the ports unless they have been specifically designed for this type of mounting.

• DO completely read and understand the information contained in this manual. The operator of the equipment must be familiar

with these instructions.

• DO stop the pump in a manner that there is no chance of the driver becoming energized while any kind of work is being performed on the pump or system.

• DO always keep safety in mind.

• DO know the operating conditions of the equipment.

• DO take proper measures and precautions to avoid spillage and overflow from overfilling or putting too much pressure on any component of the system.

• DO identify all possible hazards and decide what controls are needed.

Remember, only you understand your product and system characteristics fully.

The ultimate responsibility for the

application and safety is with you.

• DO install and properly set devices into the system to prevent the chance of dry operation, overpressure, excessive temperature, and driver overload.

• DO provide guards for all exposed rotating parts, including all parts of the drive system, to prevent possible injury.

• DO be careful when working near an operating pump. Contacting or getting caught in rotating parts may cause serious or fatal injury.

• DO keep equipment in good working order, especially safety devices and guards.

• DO be aware of your location relative to the equipment.

• DO wear proper clothing near the equipment. Safety glasses or goggles, and safety shoes are recommended. They will help reduce the chance of injury.

• DO use soft faced striking tools when the need for tapping parts into position arises.

Rubber or plastic faced striking tools are recommended.

• DO practice good housekeeping. Clean up spills immediately. Keep the work area clean to avoid hazards. Always be sure of your footing around the equipment to avoid a possible fall and injury.

• DO use proper tools. Avoid cheater bars as they are a source for serious injury should they slip or break.

• DO mount pumps in the manner they were designed to be mounted.

2.3 PREOPERATION CHECKS

Read and understand the instructions and

recommendations contained in this manual.

Disconnect the coupling between the driver and pump.

Test the rotation of the driver to make sure it will operate the pump in the desired direction of rotation. Rotation is shown on the pump in relation to the integral relief valve. When an integral relief valve is used, make sure it is positioned and adjusted as discussed in the section titled, DIRECTION OF ROTATION

AND RELIEF VALVES. After the unit is mounted and the piping is connected, the pump should be checked to be sure it operates freely without binding. After operation is proved satisfactory, both pump and driver should be tightly secured and the alignment rechecked before operation.

Before starting, make sure all guards are in place and the inlet and discharge valves are opened. After starting the unit, check to see that the pump is delivering liquid. If not, stop the driver immediately and refer to Section

2.9, CHECKING PUMP PERFORMANCE.

After the pump is delivering liquid, check the unit for excessive vibration, localized heating,

Page 2 – 3

and excessive shaft seal leakage. Check the pressure or vacuum by installing gauges at both the inlet and discharge sides of the pump to make sure the pressure or vacuum conform to specifications.

If there is no pressure relief device in the system, NEVER block the discharge line. If there is a relief valve in the system, NEVER block the discharge line between the relief valve and pump. High pressure will occur, resulting in possible damage or breakage to the pump or system parts and possible injury to personnel. DO NOT operate the pump for more than one minute with the discharge line blocked downstream of the relief valve. Rapid heating and possible damage will occur. Even an open discharge line does not prevent the possibility of high pressure. Discharge line length, diameter, and arrangement along with fluid viscosity and velocity also can create a high pressure situation at the pump.

WARNING! DO NOT overpressurize pump or system .

2.4 PREPARATION

FOUNDATION

Locate the pump so that it is as low and as close to the fluid source as practical and so that piping to and from the pump will be as short and simple as practical. The pump and its driver must be accessible for inspection and maintenance. Accessibility to the unit and adequate clearance should be a major thought in any installation. The driver must be suitable for the environment (for example; open, splash proof, totally enclosed, or explosion proof electric motor). If the driver is not suitable, choose a different location or obtain another driver.

For best pump-driver unit life, mount each unit on a strong, fabricated, structural steel baseplate with a proper foundation. A good foundation is of major importance to the total installation. A thick, heavy concrete foundation is best since it is heavy enough to support the baseplate rigidly and absorb strain and shock.

Locate anchor bolts for the baseplate in the foundation. Use a pipe sleeve, two to three times as large as the anchor bolts, around the anchor bolts to allow some lateral bolt movement during final positioning of the unit.

Place the unit, with the pump and driver mounted on the baseplate, on the foundation and disconnect the coupling (flexible coupling, belts, and sheaves, etc.). DO NOT reconnect the coupling unit until all alignment operations are complete. Support the baseplate on rectangular metal blocks and shims or on metal wedges having a small taper. Place the support pieces close to the anchor bolts and directly under the part of the baseplate carrying the greatest weight. Space the support pieces close enough to give uniform support. Allow a gap of about 3/4 inch [19 mm] to 1-1/2 inches [38mm] between the foundation and baseplate for grouting. Refer to Fig. 2.4.1.

Adjust the metal supports or wedges until the shafts of the pump and driver are level. At this time, check the faces of the inlet and discharge connections of the pump for horizontal or vertical position using a level.

Page 2 – 4

Correct the positions, if necessary, by adjusting the supports or wedges under the baseplate as required.

For maximum rigidity and lower noise levels, grout the baseplate to the foundation. Use a good grade of nonshrink grout. When all alignments are correct (refer to Section 2.5,

ALIGNING DRIVER AND PUMP), tighten the anchor bolts evenly but not too firmly. Then grout the unit to the foundation. Completely fill the baseplate with grout. It is desirable to grout the leveling pieces, shims, or wedges in place. Fill the spaces between the anchor bolts and sleeves with grout, also. Allow the grout to dry according to the manufacturer's instructions. DO NOT fully tighten the anchor bolts until the grout has hardened.

Fig. 2.4.1: Typical Baseplate Anchoring

After the grout has hardened and the anchor bolts have been properly tightened, check the unit for parallel and angular misalignment, and if necessary, take corrective measures. After the piping to the unit has been connected, check the alignment again.

NOTE: Attempts to correct alignment in one direction may alter the alignment in the other direction. Therefore, it is necessary to check alignment in all directions after making any adjustments.

Schedule semiannual inspections and checks of the foundation anchor bolts as part of a preventive maintenance program. If loose foundation bolts are found, tighten them and check the unit alignment.

Normal mounting for this pump is horizontal with the pump above the baseplate, properly grouted to a concrete foundation placed in or on solid earth. Mountings other than described above (such as vertical mounting, wall mounting, ceiling mounting, etc.) may require special components and precautions. Extra pump supports, special drivers, and extra anchor bolts may be necessary in unusual mountings. If your application requires other than normal mounting, as described above, you are urged to consult Roper Pump

Company for assistance in determining any special needs that may be required.

2.5 ALIGNING DRIVER AND

PUMP

The flexible coupling or belts and sheaves must be accurately realigned during and after installation. Refer to the flexible coupling or belt and sheave manufacturer's recommendations and instructions for the requirements for proper alignment. Also refer to Section 2.4, PREPARATION OF

FOUNDATION, for additional information.

FLEXIBLE COUPLING

DO NOT use a flexible coupling to compensate for misalignment of the driver and pump shafts. The purpose of the flexible coupling is to compensate for temperature changes and to permit end movement of the shafts without interference with each other while transmitting power from the driver to the pump.

The faces of the coupling halves should be spaced far enough apart so that they cannot strike each other when the driver rotor is moved hard over toward the pump. The necessary tools for approximate checking of the alignment of a flexible coupling are a straight edge and a taper gauge or a set of feeler gauges.

Page 2 – 5

Make sure there is no chance of the driver becoming energized while aligning driver and pump. Getting caught in rotating parts of the drive system will cause serious personal injury or death. DO NOT start or operate pump without guards in place.

WARNING! DO NOT operate without guards in place.

There are two forms of misalignment between the driver shaft and the pump shaft. The first is angular misalignment, where the axes of the shafts are concentric but not parallel. The other is parallel misalignment, where the axes of the shafts are parallel but not concentric.

Refer to Fig. 2.5.1.

Make the check for angular alignment by inserting the taper gauge or feeler gauges between the coupling faces and comparing the distance between the faces at four points spaced at 90 ° intervals around the coupling.

The unit will be in angular alignment when the measurements show that the coupling faces are the same distance apart at all points.

Fig. 2.5.1 Misalignments: Top, Angular; Center,

Parallel; Bottom, Both.

Make the check for parallel alignment by placing a straight edge across both coupling halves at the top, bottom, and at both sides.

The unit will be in parallel alignment when the straight edge rests evenly on the coupling halves at all positions. Allowance may be necessary for temperature changes and for coupling halves that DO NOT have the same outside diameter. Take care to have the straight edge parallel to the axes of the shafts.

Page 2 – 6

Correct angular and parallel misalignment by placing shims under the mounting feet of the equipment. After each change, it is necessary to recheck the alignment of the coupling halves. Adjustment in one direction may disturb adjustments already made in another direction.

BELTS AND SHEAVES

Some applications on gear pumps involving low discharge pressure and slow speeds may permit the mounting of the driven sheave directly on the pump shaft. However, it is recommended that all belt drive assemblies be designed with a separate jackshaft mounted on pillow blocks to carry the side loads of the sheaves and belts and a flexible coupling connecting the jackshaft to the pump shaft.

Make sure there is no chance of the driver becoming energized while aligning and adjusting the belts. Getting caught in rotating parts of the drive system will cause serious personal injury or death. DO

NOT start or operate pump without guards in place.

WARNING! DO NOT operate without guards in place.

The driver and pump shafts must be parallel, and the belts at right angles to these shafts.

Misalignment will cause undue belt wear, or turn-over in the grooves. Approximate alignment should be checked by placing a long straight edge evenly across the rims of both sheaves. If the faces of the sheaves are not of equal width, the alignment may be checked by resting the straight edge across the rim of the widest sheave and measuring the distance from the straight edge to the nearest belt groove with a scale. Adjust either sheave on the shaft to equalize these dimensions.

The driver should be mounted with adequate provision for belt center distance adjustment.

Provide a minus adjustment to permit belt installation without stretching and a plus allowance to provide belt take-up.

DO NOT pry, twist, or force the belts over the sheave grooves. This will damage the belts and greatly reduce the belt life. Shorten the drive by moving the driver enough to permit fitting the belts in the proper grooves. When the belts are in place, increase the center distance until proper belt tension is obtained.

Adjust take-up until only a slight bow appears on the slack side of the drive when it is operating. All the belts must be pulling evenly.

Belt tension should be reasonable. It is not necessary to have belts excessively tight.

During the first few days of operation, the belts will seat themselves in the sheave grooves.

After that, the drive must be adjusted to take up the slack. Slipping belts will result in lowered capacity. Squealing or smoking belts are sometimes a clue to the slipping of belts.

Keep belts clean and free from oil. Stop drive to clean belts. DO NOT attempt to clean belts while the drive is operating. Clean oily belts with a cloth dampened with soap and water.

Never install new belts on the same drive with used belts. DO NOT use sheaves with chipped or worn grooves. For hazardous locations, check to see if an antistatic belt should be used. When purchasing replacement belts, the same size and type should be ordered as furnished originally.

Page 2 – 7

POWER TAKE-OFF DRIVE SYSTEMS

When mounting a pump on a vehicle with a

PTO drive, always check with the manufacturer of the PTO equipment to determine the alignment required for proper operation of the PTO. The mount for the pump must be rigid. The pump must be mounted the way it was designed to be mounted. Pumps with feet must be mounted by the feet. DO

NOT use the pump ports to mount a pump that has feet. It is acceptable to mount a foot mounted pump in the three, nine, or twelve o'clock position as well as the standard six o'clock position as long as proper shaft alignment is maintained.

Make sure there is no chance of the driver becoming energized while aligning the power take-off shafting. Getting caught in a power take-off drive system will cause serious injury or death. Proper guarding must be provided for all power take-off drive systems.

WARNING! DO NOT operate without guards in place.

Serious injuries and deaths have resulted from persons becoming caught in power take-off

(PTO) drive systems. Loose or dangling clothing and slippery or unsure footing are factors in many PTO accidents. DO NOT work on or adjust a pump driven by a PTO drive system while it is operating or has a chance of the driver becoming energized except as specified in the section titled, DIRECTION OF

ROTATION and RELIEF VALVES.

Unless properly designed, guarded, and maintained, all drive systems are dangerous.

• DO be careful near rotating PTO drive systems. Contacting a PTO drive system may cause serious injury or death.

• DO install and maintain proper guard(s) for

PTO drive systems.

• DO NOT operate PTO drive systems without proper guards in place.

• DO NOT work on or adjust a pump driven by a PTO drive system while it is operating or has a chance of the driver becoming energized except as specified in the section titled, DIRECTION OF ROTATION

AND RELIEF VALVES.

• DO NOT work on a PTO drive system while it may become energized.

• DO NOT wear loose or dangling clothing or jewelry near the equipment. It could become caught and possible cause serious injury or death.

GUARDING PTO DRIVE SHAFTS

PTO drive systems can be dangerous and when used, additional safety precautions, including guarding, may be required and must be provided by the drive system installer.

Roper Pump Company has no responsibility for recommending or providing proper guarding or other safety measures in any particular application.

The installation of proper guards for the power take-off and its associated equipment is the responsibility of the drive system designer and the installer who know the particular product application and the user's exposure to danger.

The ultimate responsibility for the safe

application and installation is the user's.

SPECIAL PRECAUTIONS FOR HYDRAULIC

DRIVES

Avoid contact with high pressure fluids.

Check all hydraulic hoses.

Page 2 – 8

Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses regularly. Replace damaged hoses.

WARNING! AVOID CONTACT with high pressure fluids.

Escaping fluid under pressure can penetrate the skin causing serious injury.

Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type injury should reference a knowledgeable source.

An overload or kickdown valve in a hydraulic drive system is NOT a safe substitute for a pressure relief valve correctly installed in the pump piping system.

2.6 ADDITIONAL

IMPORTANT WARNINGS AND

INFORMATION

• This manual contains general information concerning the use, inspection, adjustment, testing, and safety considerations of the pump furnished. Other precautions and safety measures may be appropriate depending on the particular application and installation and are the responsibility of the product installer and user. Installers and users of this pump must have sufficient knowledge and training to apply sound safety and operating practices that may not be mentioned in the manual, and the sale of this pump is in reliance on such installer and

user knowledge and training.

• ROPER ® pumps are general purpose pumps for a wide range of uses; yet, they are not designed nor intended for use with

every known substance. Maximum ratings are shown in the section titled, MAXIMUM

PUMP RATINGS. ROPER ® sales brochures contain standard ratings.

Ratings for SPECification number pumps or standard pumps may be obtained by contacting Roper Pump Company or an authorized distributor.

• Review this manual to determine the proper union of the pump into the total plant or system operating programs.

• Roper Pump Company does not supply, recommend, or approve the systems in

which its pumps are or may be used.

• Identify all possible hazards. Decide upon and install the required controls. Only the installer and user can fully understand the product and system characteristics. The ultimate responsibility for the safety of the application and the system characteristics

is with the installer and user.

• Particularly note the chance of fire and burns from flammable or hot liquid spillage from burst hoses and take proper precautions.

• Properly guard all exposed rotating parts of the drive to the pump.

• Install a pressure relieving device in the system discharge piping to protect the equipment and crew from accident due to too much pressure. NEVER place a shutoff valve between the pump and system relief valve. Read Section 2.3,

PREOPERATION CHECKS.

• Spillage or overflow, from overfilling or putting too much pressure on any component of a system incorporating this pump, may result in an accident. Proper measures and precautions must be taken to avoid spillage or overflow from overfilling or putting too much pressure on any component of the system. This includes the receiver and lines.

Prior to starting pump, read sections on

PREPARATION OF FOUNDATION;

ALIGNING DRIVER AND PUMP;

INSTALLATION OF PIPES; THREADED

PORT CONNECTIONS; and

PREOPERATION CHECKS.

2.7 INSTALLATION OF PIPES

• DO NOT connect raised face flanges to the ports of a cast iron pump.

• DO use flat-faced flanges with cast iron pumps.

Piping must be installed and checked carefully. Allow for any expansion or contraction.

Any external force or moment (torque or twist) applied on the pump ports by the piping will cause stresses in the pump and its foundation.

This may cause misalignment that could result in hot bearings, worn couplings, or excessive vibration. Such forces or moments may be caused by improperly aligned piping or by thermal expansion of the piping when pumping hot or cold fluids. The piping should be supported independently. Use flexible piping connectors and insure that they are properly anchored.

Page 2 – 10

If an expansion joint is installed in the piping between the pump and the nearest point of anchor in the piping, a force equal to the area of the expansion joint (which may be considerably larger than the normal pipe size) times the pressure in the pipe will be transmitted directly to the pump. Pipe couplings that DO NOT provide an axially rigid connection have the same effect. This reaction force can be so large that it would be impractical to design suitable components to withstand the force. If an expansion joint or nonrigid coupling is used, install a pipe anchor between it and the pump. If properly installed, this will eliminate the forces mentioned above.

The pump port size does not necessarily establish the correct pipe size. Piping must be sized and arranged to provide ample inlet pressure at the pump and to insure that the discharge pressure will be at least as low as the rated pressure of the pump. If the fluid to be pumped is viscous, or the piping long, or the suction lift or static discharge head somewhat high, piping one or two sizes larger may be required. Friction losses should be carefully calculated (see Hydraulic Institute

Engineering Data Book or similar authority for friction loss data) and compared to the pump ratings before the installation is made. Where valves are used in the piping system, gate, ball, or butterfly valves are preferable to globe or angle valves. 90 ° long radius elbows or 45° elbows are preferable to standard short radius elbows. NEVER place a valve between the pump and system relief valve.

CONNECTIONS

American National Standard Taper Pipe

Threads (NPT) are standard for pipe plugs and threaded ports of the pump ports. British

Standard Pipe Threads (BSP) are available on request for most sizes.

To produce a pressure tight joint, a thread sealant must be used. TFE tape is generally not recommended where cast iron is used as one or more parts of the joint. The use of TFE tape for installing cast iron fillings may cause damage to the pump or fittings.

The following is a partial list of sealants that may be used when making up joints on the pump:

• PST Pipe Sealant No. 567 − Loctite Corp.

• Rectorseal No. 5 − The Rectorseal Corp.

• Leak Lock − Highside Chemical, Inc.

Follow the sealant manufacturer's instructions when making up a joint.

3.4 DIRECTION OF ROTATION AND RELIEF VALVES

RELIEF VALVE

The relief valve is externally adjustable by means of an adjusting screw located in the center of the relief valve cap. The range of adjustment is approximately 30 psi [207 kPa] to

125 psi [862 kPa]. The actual capability is dependent on pump speed and liquid viscosity. The settings are for full bypass; that is, all of the fluid is circulating back to the inlet through the relief valve. The end user must set the relief valve for conditions that exactly match the application.

DIRECTION OF ROTATION TAG

FIGURE 3.4.1

Page 3 – 2

RELIEF VALVE LOCATION

The relief valve may be located on either side of the case. The discharge port may be located on the top or either side of the case depending on the pump configuration and direction of the shaft rotation. Arrows on the tag will indicate which port is inlet and discharge.

RELIEF VALVE LOCATION

FIGURE 3.4.2.

Page 3 – 3

PROPER PUMP GEAR ROTATION

Proper gear rotation is shown on the warning tags attached to the relief valve faceplate.

DO NOT REVERSE ROTATION

Reversing rotation of the pump without reversing the position of the relief valve will cause the relief valve to be inoperable.

Discharge pressure will be holding the valve closed instead of pushing it open. Running the pump against the relief valve can cause very high pressure buildup on the discharge side of the pump and in the system downstream of the pump. High pressure can cause the pump or other system component to break or leak causing liquid in the system to escape resulting in possible injury or death.

PUMP INLET AND PUMP DISCHARGE

On the RV style pump, the “pump inlet” and

“pump discharge” arrows will always point directly to the inlet and discharge ports on the pump.

An integral relief valve should not be used on applications where the discharge must be closed for more than one minute.

Prolonged operation of the pump with the discharge closed will cause rapid heating of the liquid circulating through the relief valve, thus resulting in possible damage.

DIRECTION OF ROTATION FOR THE

RELIEF VALVE

Page 3 – 4

The drawings showing DIRECTION OF

ROTATION FOR PUMPS WITH AND

WITHOUT RELIEF VALVES (Figure 3.4.3.) and position of relief valve with the letter “L” in the designation are for low drive applications (the drive shaft is lower than the idler shaft). All other drawings shown are for high drive applications (the drive shaft is above the idler shaft).

The arrow in the drawing at the end of the drive shaft indicates the direction of rotation needed to achieve proper operation of the pump and relief valve when using the pump and relief valve orientation shown in the drawing. CW indicates clockwise rotations and CCW indicates counterclockwise rotation when viewed from the drive shaft end of the pump.

To determine the correct relief valve position for any of the pump orientations, use the drawings shown titled DIRECTION

OF ROTATION FOR PUMPS WITH AND

WITHOUT RELIEF VALVES (Figure 3.4.3).

1. Find the group of drawings with the proper drive shaft position (high or low drive). Drawings with W, Z, X, or Y rotation are high drive pumps. Drawings with LW, LZ, LX, or LY rotation are low drive pumps. Eliminate all other drawings.

2. In the drawings remaining, find the group of drawings with the proper direction of rotation arrow at the end of the drive shaft. Eliminate all other drawings. CW indicates clockwise rotation and CCW indicates counterclockwise rotation when viewed from the drive shaft end of the pump.

3. In the drawings remaining, find the group of drawings with the proper port positions (straight through or right angle). Eliminate all other drawings.

4. In the remaining drawings, find the drawing with the proper inlet and discharge port locations. This drawing will show the proper relief valve position for the pump configuration chosen.

Note the position of the words “PUMP

INLET” printed on the rotation plates fastened on the relief valve. The words

“PUMP INLET” must point to the inlet port of the pump in order for the relief valve to work opposite.

DO NOT operate a pump with a relief valve that is not positioned correctly.

The relief valve will be inoperable. This can allow high pressure buildup on the discharge side of the pump and in the system downstream of the pump. High pressure can cause the pump or any other system component to break or leak causing liquid in the system to escape, resulting in possible injury or death.

NOTE: The fact that the pump has the correct rotation and pumps liquid in the correct direction does not insure that the relief valve is installed in the correct position, or that it has the correct setting for the application.

3.6 INSTRUCTIONS

DRAINING PUMP

Refer to Section 3.10, PUMP SECTIONAL

DRAWING.

• WARNING! Relieve all internal fluid and air pressure inside the pump before attempting to drain the pump.

• WARNING! Take necessary precautions to prevent the pump from becoming energized while draining the pump.

• WARNING! Take necessary precautions to prevent injury or physical damage that could be caused by any loss of the product being pumped while draining the pump.

The extent to which a pump can be drained is dependent upon the product being pumped. Low viscosity products such as solvents will drain quickly and easily. High viscosity products such as molasses and tar will drain very slowly. Also, the draining of high viscosity products will be less complete.

Regardless of the product pumped, the areas at the blind end of the bearing bores and the mechanical seal chamber will not drain.

1. Refer to Section 2.0 and read sections on SAFETY PRECAUTIONS and

ADDITIONAL IMPORTANT

WARNINGS AND INFORMATION before starting procedures.

2. Loosen eight hex head cap screws (22) securing faceplate to allow a gap of 1/32 of an inch [.76 mm] between faceplate and case (1) for draining.

3. Rotate drive shaft very slowly by hand.

Each time that flow from drain increases, stop turning shaft until flow stops; then resume until flow increases again. Be sure to rotate shaft several complete revolutions in each direction until all flow from drain has stopped.

4. After draining has been completed, examine case gaskets (5) making sure gasket is not torn prior to tightening the eight hex head cap screws (22). If gasket is torn or further disassembly is required, follow steps in Section 3.7,

MAINTENANCE QUESTIONS

Question:

At what point do I need to overhaul my pump?

Answer:

As with all rotating equipment, your pump will eventually wear to a point where the pump's performance is diminished. The pump's performance is dependent upon the application. For instance, a very worn pump may work at an acceptable level in an application involving a high viscosity (thick) liquid when combined with low discharge pressure. This same pump would most likely be unsatisfactory in a low viscosity, high pressure application. The best answer to the above question is the following: You need to overhaul your pump when you feel that the performance has dropped to an unacceptable level for your application.

If you have set up your own test procedure to check your used pumps, it will be helpful to test at least one new pump of each size to use as a benchmark for setting your own acceptance levels.

Question:

What parts will I need to replace to get my pump back to “like-new” condition?

Answer:

As a general rule, replace all gaskets, o-rings, and lip seals at each servicing regardless of their apparent condition.

These parts are usually less expensive than the labor costs and downtime incurred if the pump has to be serviced a second time to stop a leak.

The parts subject to wear should be examined for obvious wear and corrosion.

This includes bearings, shafts, gears, cases, and endplates. Measurements should be made and compared to the dimensions shown in Section 3.8. Replace any parts that are worn beyond the limit shown.

If the pump is used exclusively in an abrasive application or high viscosity application, you may be able to extend the life of the gears or case. If the gears show heavy wear on only one side of the tooth, very little wear on the ends and O.D., the gears can be turned over, end-for-end, in the pump. This will put the previously unworn sides of the gear teeth in contact.

Similarly, if your pump has a case with straight through ports and it is worn on the inlet side only, the case can be turned around and used again.

Question:

What do I look for to determine excessive wear?

• Gears

The gears are serviceable if there is no degradation of the teeth or end faces.

Check for uniform wear. There should be no burrs or gouges on any of the gear's surfaces.

• Bearings

If bearing or bearing seals are worn or damaged, they should be replaced.

• Cases

Excessive case wear is usually the result of worn bearings or shafts allowing gears to contact the case bores. Minor rubbing of the case bore is normal.

• Shafts

Replace the shaft if it is scored in the seal or bearing area.

• Endplates

Excessive wear is usually the result of pumping products containing abrasives. If the endplates are damaged in the area that the ends of gears rub, they should be replaced.

Question:

Do I need special tools to disassemble and reassemble my pump?

Answer:

The only special tools required are for removal of the bearings.

Page 3 – 23

Question:

How long can my pump run dry?

Answer:

One minute is a practical maximum for running a pump dry. Anything longer could cause the pump to overheat resulting in possible pump damage or failure.

Question:

At what point should I buy a new pump?

Answer:

A new pump should be purchased when the old pump cannot be economically repaired.

Question:

Are there service centers where I can get my pump repaired?

Answer:

Most Roper Pump Company distributors are able to repair pumps. Consult the factory to find your nearest distributor. Also, Roper

Pump Company has a repair department.

Any pump repaired at the factory is rebuilt to like-new condition and carries a new pump warranty. Pumps may be returned to the factory by an authorized ROPER ® pump distributor.
