A - GENERAL INFORMATION

TO THE PURCHASER:

Congratulations! You are the owner of one of the fi nest pumps on the market today. These pumps are products engineered and manufactured of high quality components.

With years of pump building experience along with a continuing quality assurance program combine to produce a pump which will stand up to the toughest applications.

2. FOUNDATION

The pump foundation should be suffi ciently substantial to form a level, rigid support for the combined weight of the pump and driver and maintain alignment of the installed unit. Foundation bolts, of the proper size, should be imbedded in the concrete. A pipe sleeve, about 2½” diameters larger than the bolt, should be used to allow for fi nal positioning of the bolts. See Figure 1.

Check local codes and requirements before installation.

Servicing should be performed by knowledgeable pump service contractors or authorized service stations.

RECEIVING:

Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, fi le a claim immediately with the company that delivered the pump.

If the manual is removed from the crating, do not lose or misplace.

STORAGE:

Short Term - Pumps are manufactured for effi cient performance following long inoperative periods in storage.

For best results, pumps can be retained in storage, as factory assembled, in a dry atmosphere with constant temperatures for up to six (6) months.

Long Term - Any length of time exceeding six (6) months, but not more than twenty four (24) months. The units should be stored in a temperature controlled area, a roofed over walled enclosure that provides protection from the elements (rain, snow, wind blown dust, etc..), and whose temperature can be maintained between +40 deg. F and

+120 deg. F. Pump should be stored in its original shipping container and before initial start up, rotate impeller by hand to assure seal and impeller rotate freely.

3. MOUNTING:

Pumps and drivers that are received from the factory with both machines mounted on a common base plate, were accurately aligned before shipment. All baseplates are fl exible to some extent and, therefore, must not be relied upon to maintain the factory alignment. Preliminary alignment is necessary after the complete unit has been leveled on the foundation, and again, after the unit is piped, and rechecked periodically as outlined in the following paragraphs.

B - INSTALLATION

1. LOCATION

The pump should be installed as near the source of liquid as possible with a minimum of piping on the suction side of the pump. The discharge piping should be as direct as possible with a minimum of fi ttings to lower friction loss.

The unit should be installed with adequate head room and a maximum area for inspection and service. The installation should be dry, well ventilated, and protected against moisture and fl ooding.

Position unit on foundation and level the base plate, using rectangular metal blocks and shims, or wedges having a small taper. A gap of 3/4” to 1½” should be allowed between the base plate and foundation for grouting.

Adjust the metal supports or wedges until the shafts of the pump and driver are level. Check the coupling faces, as well as the suction and discharge fl anges of the pump for horizontal or vertical position by means of a level.

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

4. FLEXIBLE COUPLING ALIGNMENT

A fl exible coupling should not be used to compensate for misalignment of the pump and driver shafts. The purpose of the fl exible 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.

ANGULAR

MISALIGNMENT

CAUTION! - Remove and lock out power to

driver.

FACTORY ALIGNMENT

Pump and drivers that are received from the factory with both machines mounted on a common baseplate, were accurately aligned before shipment. All baseplates are fl exible to some extent and, therefore, must not be relied upon to maintain the factory alignment. Preliminary alignment is necessary after the complete unit has been leveled on the foundation and again, after the unit is piped, and rechecked periodically as outlined in the following paragraphs.

FIELD ALIGNMENT - Horizontal Units

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 toward the pump. The necessary tools for checking the alignment of a fl exible coupling are a straight edge and a taper gauge or a set of feeler gauges.

NOTE: In most cases where extreme

accuracy is necessary, a dial indicator may be used to align coupling.

Angular alignment check is made by inserting a taper gauge or feelers between the coupling faces at 90-degree intervals around the coupling. The unit will be in angular alignment when the coupling faces are exactly the same distance apart at all points. (See Figure 2).

PARALLEL

MISALIGNMENT

Parallel alignment check is made by placing a straight edge across both coupling rims at the top, bottom and at both sides. The unit will be in parallel alignment when the straight edge rests evenly on the coupling rim at all positions. Allowance may be necessary for temperature changes and for coupling halves that are not of the same outside diameter. Care must be taken to have the straight edge parallel to the axis of the shafts. Correction for

Angular and Parallel Misalignment is made by adjusting the shims under the driver. After each change, it is necessary to recheck the alignment of the coupling halves, as adjustment in one direction may disturb adjustments already made in another direction.

The permissible amount of coupling misalignment will vary with the type of pump and driver, but should be limited to approximately .002 inches per inch of shaft diameter when fi nal adjustment is made. When the units are lined up cold, it is necessary to make allowance for the vertical rise of the driver caused by heating when in operation. When the preliminary alignment has been completed the foundation, bolts should be tightened evenly, but not too fi rmly.

ALIGMENT

Figure 3

WARNING - Coupling guards must be used to avoid serious injury to operating personnel.

FIELD ALIGNMENT - Vertical Units

To protect the pump and motor during shipment, the motor and fl exible shaft coupling may be shipped unmounted and must be installed on the pump and properly aligned at the pump site. Clamp an extender to the pump shaft and by using a dial indicator, positioned against the fi nished bore of the top plate of the vertical frame, rotate the pump shaft checking alignment of the pump shaft with the vertical mounting frame. Use the jackscrews in the base of the mounting frame or metal shims under the feet of the pump casing and adjust the pump so that the T.I.R. is within .004”. Lock jack screws with the jam nuts. The shaft position in relation to the fi nished surface at the top plate of the mounting frame should be within T.I.R. of .005”.

Install coupling halves on motor shaft and pump shaft but do not tighten coupling set screws. Position the motor over the pump and complete the coupling assembly according to manufacturer’s recommendation, as the motor comes to rest on the top plate of the vertical mounting frame. Insert and tighten the motor cap screws.

It is recommended that the motor and pump be dowelled to the vertical mounting frame when the correct alignment has been established. Use Loctite on all dowel pins.

5. GROUTING

Grouting compensates for unevenness in the foundation and prevents vibration and shifting after mounting is complete. Build a form around the base plate to contain the grout, and sprinkle area with water to obtain a good bond. The base should be completely fi lled with a good quality, non-shrinking grout. The usual mixture for grouting is one part Portland cement and two parts sand with suffi cient water to fl ow freely. It is also desirable to grout the leveling pieces, shims or wedges in place. Foundation bolts should be fully tightened when grout has hardened, usually about 48 hours after pouring.

6. PIPING

The pump suction and discharge connections are not intended to indicate the required suction and discharge pipe sizes. The pipe diameter must be selected according to the requirements of the pumping system and recommended friction losses for the liquid being pumped.

Using an indicator on both the motor shaft and the pump shaft, make sure that the shafts are concentric within .004” and are aligned axially. Tighten coupling set screws.

Usually, it is advisable to increase the size of both the suction and discharge pipes at the pump nozzles to have minimum acceptable friction loss, suction pipe should never be smaller in diameter than the pump suction nozzle. When suction pipe is of larger diameter than the pump suction nozzle, an eccentric reducer is required to eliminate possible air or vapor pockets at the pump suction inlet.

6

Figure 4

7

Both suction and discharge pipes must be supported independently near the pump, so that when piping is connected to the pump, no strain will be transmitted to the pump. Piping should be arranged with as few bends as possible, and, preferably, with long radius elbow whenever possible.

Where vibration noises must be kept to a minimum a fl exible connection is recommended on both the suction and discharge lines. This will eliminate any sound being telegraphed through the pipe system.

7. LUBRICATION

Grease Lubricated Bearings

Grease lubricated bearings are prelubricated at the factory before shipment. See LUBRICATION Section C for recommended lubricants.

Oil Lubricated Bearings

Pumps furnished with oil lubricated bearings are shipped

WITHOUT oil in the housings (31) & (33). To fi ll the oil reservoir in the housing:

1. Install the Trico Opto-Matic constant level oiler (125) with piping as shown with the moveable oiler body at its lowest position.

NOTE: Flexible connector should have limiting bolts to contain hydraulic forces.

SUCTION PIPING

A horizontal suction line must have a gradual rise to the pump. Any high point in the suction pipe can become fi lled with air and prevent proper operation of the pump and may cause loss of prime. The pipe and fi ttings must be free of all air leaks.

Any valves or fi ttings should located at a distance equal to 5 to 10 times the diameter of the suction pipe from the pump suction nozzle. If an elbow must be installed at the pump suction, it should be installed in a vertical position to reduce unequal fl ow into the pump, which may cause cavitation in the pump (See Figure 4).

2. Unscrew the plastic bottle from the oiler.

Fill bottle of the oiler and screw ir onto the lower before the oil level in the bearing reservoir is equal to the level for which the oiler is adjusted. NEVER

FILL FRAME RESERVOIR THRU LOWER

RESERVOIR OF THE OILER. See LUBRICATION,

Section C, for recommended lubricants. When proper oil level is obtained, refi ll and replace the plastic bottle on the oiler. See LUBRICATION,

Section C, for proper oil level.

Packing Box

The pump may be furnished with packing or mechanical shaft seal, as ordered.

There is always uneven fl ow in an elbow when it is installed in any position other than a vertical position. This unequal fl ow allows more water to enter one side of the impeller than enters the other side causing a reduction in capacity and effi ciency. This condition may also cause cavitation which would be characterized by noisy operation and shorter pump life.

An eccentric rather than straight reducer and gate vale with stem horizontal rather than vertical should be installed in suction piping. (See Figure 4).

Packing is continuously lubricated internally with pumped fl uid. External lubrication may be provided through tapping opening, provided by-pass is plugged with item (263).

Mechanical seals ca be lubricated by:

1. The internal by-pass which leads from the volute to the packing box. When using the internal by-pass it is recommended that the tap in the seal gland be used for the vent.

NOTE: A gate valve in the suction piping should not be used as a throttling device, as this may cause the liquid to overheat during operation.

DISCHARGE PIPING

A silent type check valve and a gate valve should be installed in the discharge line. The check valve, placed between the pump and the gate valve, is to protect the pump against pressure surges and to prevent water running back through the pump in case of failure of the driver. The gate valve is used in priming, starting and when shutting down the pump. This is especially important when the pump is operated against a high static head. if increasers are used on the discharge side increase the size of discharge piping, they should be placed between the check valve and pump.

2. Plugging the internal by-pass with a socket head pipe plug (263) and using an outside source. When using an outside source, it is recommended to use the tap in the seal gland for the inlet and outside tap of the internal by-pass for the vent.

Other Lubrication

For proper lubrication of driver bearings and shaft couplings, see manufactures instructions.

8. WIRING

For electric motor drives, connect power supply to conform with national and local codes. Line voltage and wire capacity must match the ratings stamped on the motor nameplate.

9. ROTATION

Before starting the pump, check the required direction of rotation of the pump. The proper direction is indicated by a direction arrow on the pump casing. Separate the coupling halves, then start motor to see that it rotates in the direction required by the pump. If it does not, reverse any two main leads of the 3-phase wiring to the motor.

The coupling halves can be reconnected and the pump primed for starting.

8

C - OPERATION

1. PRIMING

Install pet cock (248) on top of casing as shown.

CAUTION: Before starting the pump, the casing and suction line must be fi lled with liquid. The pump must not be run until it is completely fi lled with liquid, because of danger of injuring some of the parts of the pump which depend upon liquid for lubrication. Wearing rings will not seize when the pump is fi lled with liquid but are very liable to do so when the pump is run dry.

Vertical units must be primed through the recirculation line at the top inboard seal gland.

Priming By Suction Pressure

When operating with suction pressure (fl ooded suction), priming may be accomplished by bleeding all the air out of the pump by opening the petcock located at the top of the upper casing or at the top seal gland.

Priming by Vacuum Pump

When neither of the above methods of priming are practical, the pump may be primed by the use of a vacuum pump to exhaust the air from the pump casing and suction line. A wet vacuum pump is preferable, as it will not be injured if water enters it. When a dry vacuum pump is used, the installation must be such as to prevent liquid being taken into the air pump. The vacuum pump manufacturer’s instructions should be followed.

2. STARTING THE PUMP

Position of Discharge Valve on Starting

A high or medium head centrifugal pump, when primed and operated at full speed with the discharge gate valve closed, requires much less power than when operated at its rated capacity and head with the discharge gate valve open. For this reason it is usually advantageous to have the discharge gate valve closed when the pump is being started. The pump must not be throttled by the use of a valve in the suction line.

A pump operating under a suction lift may be primed by any of the following methods, as may be best suited to the conditions. The discharge valve should be closed during priming operation.

Priming by Ejector or Exhauster

This method is used when steam, high pressure water, or compressed air is available.

1. Attach an air ejector to the highest point in the pump

casing. This will remove the air from the pump and line.

WARNING! - Operating the pump with a closed discharge valve can result in excessive heat build-up and should be limited to the shortest practical duration. Operating the pump at close to shut-off head usually places greater bending strains on the shaft than at operating points near the best effi ciency.

The following important items should be checked as pump is started and placed in operation.

Vertical units must be primed through the recirculation

line at the top inboard seal gland.

2. As soon as the ejector waste pipe throws water

continuously, the pump may be started. After starting, a

steady stream of water from the waste pipe indicates

the pump is primed. If this stream of water is not

obtained, the pump must be stopped at once and the

process of priming repeated. A foot valve is unnecessary

when this kind of device is used.

3. Open the discharge valve slowly and close off the ejector.

a. Pump and driver securely bolted b. Coupling properly aligned c. Piping complete d. Correct pump rotation e. Pump shaft turns freely f. Discharge valve closed g. Suction valve open (if used) h. Coupling Guard installed i. Pump fully primed j. Pump and driver properly lubricated k. Seal water valve (if used) open

Priming With Foot Valve

When it is not practicable to prime by ejector or exhauster, the pump may be primed by the use of a foot valve. The foot valve will prevent liquid running out through the suction inlet and the pump can be completely fi lled with liquid from some outside source. Pet cocks on the top of the pump should be opened during fi lling to allow the air to escape.

A tight foot valve will keep the pump constantly primed so that the pump may be used for automatic operation. The valve must be inspected frequently, however, to see that it does not develop leaks and thus allow the pump to be started dry.

Only after these items have been checked should the pump be started.

3. INITIAL ADJUSTMENTS

Open discharge valve as soon as operating speed has been reached. After the pump has been started the packing box glands should be tightened to eliminate excessive liquid loss. (Applies only to pumps having packed stuffi ng boxes.) Packing should not be pressed too tight, as this may result in burning the packing and scoring the shaft or shaft sleeve. The best adjustment will allow the liquid to drip slowly from the packing box gland. This will permit proper lubrication of the shaft and dissipate generated heat.

9

As soon as the pump and driver have reached the normal operating temperature, the unit should be shut down for fi nal coupling alignment. This should be done by following the instructions found in Section B, Part 4.

2. PACKING BOX

The packing glands should be adjusted occasionally to insure proper packing lubrication. A slow dripping through the gland is recommended for good lubrication and long packing and shaft sleeve life.

After the unit has been running for about one week, the coupling halves should be given a fi nal check for misalignment caused by pipe strains or temperature strains. If the alignment is correct, both pump and driver may be dowelled to the baseplate if desired.

When installing new rings of packing, clean packing box and inspect parts for any damage. If the shaft sleeve is worn or grooved, it should be replaced. New packing will not do an adequate sealing job on a worn shaft sleeve.

D. MAINTENANCE

1. LUBRICATION

Grease Lubricated Pump

Pump bearings are properly lubricated with grease at the factory before shipment. Periods of subsequent lubrication depend on local conditions, loads, speeds, hours of operation and temperature.

Insert two new rings of packing in front of lantern ring.

Stagger joints to minimize leakage.

Tamp each ring in place. Replace lantern ring. Add two rings of packing behind lantern ring. Replace gland and bolts, rotate shaft and tighten gland securely. Loosen the gland and add the fi nal ring of packing. Be sure lantern ring is positioned to receive lubrication through orifi ce.

Tighten nuts securely to seat packing and rotate shaft.

After rotating several turns, loosen nuts to fi nger tight for starting.

Periodic inspection of bearing lubrication should be made and additional grease added as needed. At this time the plug in the bottom of the bearing cover should be removed and the bearing fl ushed with clean grease. A Chevron

SRI-2 or Shell Dolium “R” grease is recommended for most installations. Do not overgrease as this causes high bearing temperatures and shortens bearing life. The pump should be run a short time to eject any excess grease and the plug then replaced in the bearing cover.

Oil Lubricated Pump

The pump is shipped without oil in the bearing housings.

Fill the reservoir to the proper level from shaft centerline as follows:

3. WEARING RINGS

Wearing rings are fi tted in the casing on all pumps and are standard on the impeller of all pumps with 8” or larger discharge. (Optional on smaller units). These wearing rings provide a close running clearance, to reduce the quantity of liquid leaking from the high pressure side to the suction side. These rings depend on the liquid in the pump for lubrication. They will eventually wear so that the clearance becomes greater and more liquid passes into the suction.

This rate of wear depends on the character of the liquid pumped. When worn excessively these rings will cause the pump to loose effi ciency and should be replaced.

Recommended wear ring clearances are as follows:

The following lubricants are recommended at the operating temperature indicated. See Figure 5 for correct oil levels.

nameplates b. Head lower than rating - pumps too much liquid.

Check system requirements c. Liquid specifi c gravity or viscosity greater than

expected. Requires large motor.

d. Pump and driver misalignment - Check casing for

pipe strain. Support piping and realign unit e. Wrong direction of rotation f. Electrical defects - Check power supply and motor g. Impeller oversized for system requirements h. Partial freezing or thickening of liquid when

pumped. Check liquid characteristics.

1. Bent pump shaft.

2. Impeller binds in casing - Check impeller

adjustment

6. Excessive Pump Vibration a. Cavitation at pump suction due to insuffi cient

NPSHA. Alter installation to reduce NPSHR b. Impeller out of balance - Check mechanical c. Pump and motor misalignment d. Obstruction in pump impeller e. Pump shaft bent f. Worn pump bearings g. Impeller imbalance due to wear or corrosion h. Motor imbalance i. Base plate loose on foundation or insuffi cient

strength to support the load

7. Pump and/or Motor Noise a. Pump and motor misalignment b. Pump cavitation c. Base plate loose or not grouted d. Pump bearings worn e. Motor bearings worn or fan rubs housing f. Foreign matter in pump h. Liquid velocity in pump or valves due to greater i. Pump impeller imbalance due to wear.
