SAFETY WARNINGS

Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.

WARNING

A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel can explode,rupture, or discharge its contents if sufficiently over pressurized causing death, personal injury, propertydamage, and/or damage to the environment. All necessary measures must be taken to ensure over

pressurization does not occur.

WARNING

Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage andresult in a violent explosion. All necessary measures must be taken by the end user to ensure this condition isavoided.

WARNINGThe pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pumpand eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, butare not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.

WARNING

Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods fordisassembling pumping units. These methods must be adhered to.

SITE/FOUNDATIONA pump should be located near the supply of liquid in aclean dry area free from flooding. The area should provideadequate space for operation, maintenance, and inspection,considering complete disassembly and handling of equipment.

The pump support must be sufficiently substantial and levelto give rigid support to the pump and absorb vibration.

The location and size of the mounting holes are shown onthe outline assembly drawing supplied with the pumporder. The bolts which secure the pump to the foundationshould be 1/8 less in diameter than the hole size.

SUMPThe sump must be screened to prevent any foreign objectsfrom falling into the sump and damaging the pump. Theopenings in the screening should be smaller than theopenings in the pump impeller. Guidelines for sump designcan be found in the Hydraulic Institute Standards for sumpdesign.

VRS IOM - 5/08 11


18/40

LEVEL THE PUMPLeveling the pump is best performed without the drive andmotor installed. Loosen the (4) bearing frame hold down bolts. Level the bearing housing to within 0.010 in.(0.25 mm). Place shims between bearing housing andsupport so that a gap of no more than 0.002 in (0.05 mm)

exists at any of the (4) anchor bolts when the bolts are

loose. Tighten the anchor bolts. If a floorplate is used, shimeach anchor bolt location so that a gap of no more than0.002 in (0.05mm) exists at any of the anchor bolt locationswhen the bolts are loose.

ALIGNMENT PROCEDURE

! WARNING Before beginning any alignment procedur, make suredriver power is locked out.

Check the alignment twice:

Initial Alignment is done prior to operation when the pump and driver are at ambient temperature.

Final Alignment is done just after operation when the pump and driver are at operating temperature.

NOTE: Proper alignment is the responsibility of theinstaller and user of the unit.

Accurate alignment of the equipment must be attained.Trouble free operation can be accomplished by followingthese procedures.

ALIGNMENT CHECKS

Initial Alignment (Cold Alignment)

Before Connecting Piping - To be sure alignment can beobtained.

After Connecting Piping - To ensure pipe strains havenot altered alignment. If changes have occurred, alter piping to remove pipe strains on pump flanges.

Final Alignment (Hot Alignment)

After First Run - To obtain correct alignment when both pump and driver are at operating temperature. Thereafter,alignment should be checked periodically in accordancewith plant operating procedures.

V-BELT DRIVE PUMPS

! WARNING Before beginning any alignment procedure, make suredriver power is locked out.

1. Place a straight edge across the top of the motor and pump sheaves to measure the angular and parallelmisalignment (see Figure 2). Measure the gap betweenthe straight edge and the sheaves with feeler gauges. If the gap exceeds 0.010 in (0.25 mm), adjust the sheavesalong the shafts to correct parallel misalignment andshim the motor to correct angular misalignment.

2. A dial indicator can be used to check runout on the

periphery and face of each sheave.

DIRECT CONNECT PUMPS

ALIGNMENT CRITERIADisconnect coupling halves before proceeding with thealignment. Check for parallel and angular alignment witheither the Dial Indicator Method or the Straight EdgeMethod outlined below.

The faces and outside diameters of the coupling halvesmust be square and concentric with the bores. Goodalignment is achieved when the dial indicator readings for both parallel and angular misalignment are 0.003 in(0.076 mm) total indicator reading (TIR) or less when the pump and driver are at operating temperature (see FinalAlignment). Figure 3 provides a representation of what tolook for.

SET UP

! WARNING Before beginning any alignment procedure, make suredriver power is locked out.

1. Mount two dial indicators on one of the couplinghalves (X) so that they contact the other coupling half (Y) as shown in Figure 4.

2. Check setting of indicators by rotating coupling half Xto ensure indicators stay in contact with coupling half Y but do not bottom out. Adjust indicatorsaccordingly.

MEASUREMENT TECHNIQUES1. To ensure accuracy of indicator readings, always rotate

both coupling halves together so indicators contact thesame point on coupling half Y. This will eliminate anymeasurement problems due to runout on coupling half Y.

2. Take indicator measurements with driver hold down bolts tightened. Loosen hold down bolts prior to

making alignment corrections.3. Take care not to damage indicators when moving

driver during alignment corrections.

ANGULAR ALIGNMENTA unit is in angular alignment when indicator A (Angular Indicator), Figure 3, does not vary by more than 0.003 in(0.076 mm) as measured at four points on the coupling periphery 90 degrees apart at operating temperature. Thereare two methods outlined below which are acceptable toachieve alignment.

20/40

METHOD 1 - DIAL INDICATOR METHOD

For the following steps, refer to Figure 5.

1. Zero indicator A at position 1 of coupling half Y. Mark this position on both flanges.

2. Rotate both flanges 180 degrees to position 3. Observeneedle and record reading.

3. Negative Reading - The coupling halves are further apart at position 3 than position 1.

Positive Reading - The coupling halves are closer at position 3 than position 1.

4. The angular alignment should not be a problem. If,however, 0.003 in (0.076 mm) TIR or less is notattainable, check the motor and motor mount for perpendicularity to their respective centerlines.

5. Repeat steps 1 through 4 substituting position 2 for position 1 and position 4 for position 3. Use the samemarks made on the coupling from position 1 and besure to turn the coupling halves together.

METHOD 2 - FEELER GAUGE METHOD

For the following steps refer to Figure 5.

1. Insert a feeler gauge at position 1 at the periphery of the couplings. Mark this position on both flanges.

2. Record the largest gauge size which fits snugly between the two flanges.

3. Rotate both flanges 180 degrees to position 3.

4. Insert a feeler gauge at position 3 at the periphery of the couplings.

5. Record the largest gauge size which fits snugly between the two flanges.

6. Calculate the difference between the readings at positions 1 and 3. The difference should not be greater than 0.003 in (0.076 mm). If, however, 0.003 in (0.076mm) TIR or less is not attainable, check the motor andmotor mount for perpendicularity to their respectivecenterlines.

7. Repeat steps 1 through 6 substituting position 2 for position 1 and position 4 for position 3. Use the samemarks made on the coupling from position 1 and besure to turn the coupling halves together.

PARALLEL ALIGNMENT

The unit is in parallel alignment when indicator P (ParallelIndicator, see Figure 4) does not vary by more than 0.003in (0.076 mm) as measured at four points on the coupling periphery 90 degrees apart at operating temperature. Thereare two methods outlined below which are acceptable toachieve alignment.

METHOD 1 - DIAL INDICATOR METHOD


1. Zero indicator P at position 1 of coupling half Y. Mark this position on both flanges.

2. Rotate both flanges 180 degrees to position 3. Observethe needle and record the reading.

3. Negative Reading - The coupling half Y is shiftedtoward position 1. If the value is greater than 0.003 in(0.076 mm), shift the motor accordingly.

Positive Reading - The coupling half Y is shifted toward position 3. If the value is greater than 0.003 in (0.076 mm),shift the motor accordingly.

4. Repeat steps 1 through 3 until indicator P reads 0.003in (0.076 mm) or less.

5. Once ideal alignment is reached, repeat steps 1 through4 substituting position 2 for position 1 and position 4for position 3.

METHOD 2 - STRAIGHT EDGE METHOD


1. Place a straight edge across the two coupling flanges at position 1 and mark this position on both flanges.

2. Adjust the motor so that the straight edge rests evenlyon both flanges within 0.003 in (0.076 mm).

3. Rotate both flanges to position 2 and repeat steps 1 and2.

4. The unit will be in parallel alignment when the straightedge rests evenly within 0.003 in (0.076 mm) on the

coupling periphery at both positions along the periphery.

NOTE: Care must be taken to have the straight edge parallel to the axis of the shafts.

TIP: Since the coupling halves are disconnected, this would be a good time to check the direction of motor rotation.

FACTORS THAT MAY AFFECTALIGNMENT

CAUTIONThe unit should be checked periodically for alignment.

If the unit does not stay aligned after being properlyinstalled, it may be due to any of the following causes:

1. Non-rigid foundation

2. Foundation settling

3. Bearing wear

14 VRS IOM - 5/08


21/40

4. Distortion due to piping loads/strain

5. Distortion of support due to an adjacent heat source

6. Structural changes due to variable loading or other causes

7. Loose nuts/bolts on the pump and/or drive assembly

PIPINGGENERALReview the guidelines for piping in the Hydraulic InstituteStandards prior to pump installation.

1. All piping must be supported independently of, andline up naturally with, the pump flanges.

CAUTION Never draw piping into place by forcing the flanged connections of the pump. This may impose dangerous strains on the unit and cause misalignment between pump and driver. Pipe strain will adversely affect thereliability of the pump.

2. Piping runs should be as short as possible to minimizefriction losses.

3. Arrangements should be made to keep the pump from back spinning severely during shutdown. In situationswhere this occurs, a non-slam check valve should beinstalled.

CAUTION Do not start the pump while the impeller is in reverserotation.

FINAL PIPINGCHECK After Connecting the Piping to Pump:

1. Turn the shaft several times by hand to confirm freerotation.

2. Check alignment per the procedure outlined earlier. If pipe strain is affecting alignment, it must be corrected prior to startup.

PREPARATION FOR START-UPPUMPSUPPORTBefore starting a newly installed pump, check the pumpsupports and piping to be certain that they conform to thespecifications in the Installation section of this manual.

BEARING LUBRICATIONThe bearings must have adequate lubrication. The bearingswere properly filled with grease prior to shipment.Regrease bearings if pump was disassembled. Refer to theMaintenance of Bearings section.

SHAFT ROTATIONThe pump shaft must turn without any binding or rubbing -only the uniform frictional drag of the bearings should befelt. If the pump does not turn freely by hand, check todetermine the cause of the binding.

CORRECT DRIVER ROTATION

CAUTION Incorrect rotation could result in considerable damageto the pump. Check the motor rotation when motor isnot connected to the pump shaft.

The direction of rotation of the driver must be checked before it can be coupled to the pump. The correct directionof rotation of the pump is indicated on the bearing frame.Since the impeller is threaded on, reverse rotation couldcause the impeller to unscrew from the shaft.

! WARNING Lock out driver power to prevent accidental start-upwhen working on drive.

1. Lock out power to driver.

2. Disconnect coupling from the driver or the belts fromthe drive. Make sure no parts are loose.

3. Unlock driver power.

4. Make sure everyone is clear of driver. Jog the driver just long enough to determine the direction of rotation.Rotation must correspond to the arrow on the pump.

5. Lockout power to driver and reinstall coupling or belts.

6. Reinstall coupling or belt drive guard.

PRIMINGThe liquid level must be above that shown on thedimensional drawing supplied with the order.

START THE PUMP

! WARNINGThis unit must never be used without proper installation of the safety guards for rotating parts.

1. Make sure the liquid level is at or above the minimum.

2. Slightly open the discharge valve.

3. Start driver.

CAUTION Immediately observe the discharge gauge after starting pump. If discharge pressure is not quickly obtained,

stop the driver, check the liquid level and dischargevalve, and attempt to restart.

4. Slowly open the discharge valve.

RUNNING PUMP

GENERALCONSIDERATIONSDriver may overload if the pumpage specific gravity(density) is greater than originally assumed or the ratedflow rate is exceeded.

Always operate the pump at or near the rated conditions to prevent damage resulting from cavitation or recirculation.

New bearing housing seals may generate some heat until broken in. Oil should be applied to them if heat becomesexcessive.

OPERATING AT REDUCEDCAPACITY

! WARNING Do NOT operate pump below minimum rated flows or with the discharge valve closed. These conditions canquickly lead to pump failure and a possible explosion.

Damage caused by reduced flow operations includes:

1. Increased Vibration Levels - Affects bearings.

2. Increased Radial Thrust - Stresses on shaft and bearings.

3. Heat Build Up - Vaporization causing rotating parts toscore or seize or possible explosion.

FINALALIGNMENT1. Run the pump under actual conditions for a sufficient

length of time to bring the pump and driver up tooperating temperature.

2. Check the alignment per alignment procedure outlinedearlier.

GENERAL COMMENTSA routine maintenance program can extend the life of your pump. Well maintained equipment will last longer andrequire fewer repairs. A maintenance record will helpidentify the potential causes of problems.

MAINTENANCE SCHEDULERoutine Maintenance

Bearing Lubrication Vibration Analysis

Routine Inspections

Check for unusual noise, vibration and bearingtemperature

Inspect pump and piping for leaks Check temperature of bearings Observe discharge pressure

Quarterly Inspections

Check hold down bolts for tightness

Yearly Inspections

Check pump capacity, pressure, and power. If the pump performance does not satisfy your processrequirements, the pump should be disassembled andinspected. Worn parts should be replaced.

VRS IOM - 5/08 19


26/40

MAINTENANCE OF BEARINGSThe bearings have been adequately greased prior toshipment. Under normal operating conditions, add greasemonthly or after 500 operating hours, whichever occursfirst. Add approximately (4) pumps to the inboard fittingand outboard fitting. Use a lithium based NLGI 2 grease to

match the type used when the pump was initially built.

CAUTION Never mix greases of different consistency (NLGI 1 or 3 with NLGI 2) or different thickener soaps (sodium or calcium with lithium). The consistency usuallybecomes softer and will not provide adequatelubrication to the bearings.

NOTE: When regreasing there is a possibility of impurities entering the bearing housing. The greasecontainer, the greasing device, and the fittings must beclean.

Acceptable Greases:Shell Alvania No. 2Mobil Mobilux EP No. 2Texaco Multifak No. 2Sun Oil Co. Prestige No. 42American Oil Co. Amolith Grease No. 2

MAINTENANCE OF SEALSWhen it becomes necessary to replace the bearing housingseals, the housing and the bearings should be flushed cleanwith a solvent and repacked with new grease. Overpackingresults in excessive bearing temperature.

MAINTENANCE OF DRIVE

Well designed and properly installed V-belt drives arecapable of running for years without maintenance. Thereare a few points that should be checked periodically.

Sheave Alignment - Alignment must be maintainedfor full power transmission, minimum vibration, andlong drive life.

Belt Installation - When installing new belts, shortenthe center distance between sheaves so that the beltscan be placed on the sheave without the use of force. Never roll or pry the belts into place, as this coulddamage the belt cords.

Check Belt Fit - Regardless of the belt section used,the belt should never be allowed to bottom in thegroove. This will cause the belts to lose their wedgingaction and allow slippage. Replace such sheaves or belts.

Maintain Proper Belt Tension - Tension is essentialfor long belt life. Improper tension could cause beltfatigue and/or hot bearings. Methods of determining proper belt tension can be obtained from the drivemanufacturer.

Use Belt Guards - Belt guards protect personnel fromdanger and the drive from contamination. Inspect

periodically to assure that belts do not rub againstguard. Keep Belts Clean - Dirt and grease reduce belt life.

Belt dressing affects performance only temporarilyand is never recommended. Maintaining a clean driveis a better idea.

If any questions arise pertaining to the drive limitations,consult the manufacturer.

IMPELLER CLEARANCE SETTINGA change in pump performance may be noted over time bya drop in head or flow or an increase in power required.Performance can usually be restored by adjusting theimpeller clearance. Each application is different and henceit is necessary to monitor the amount of wear over a certain

period of time in order to set up an adjustment schedule.Other factors which may indicate that impeller adjustmentis required are:

High thrust bearing temperatures resulting fromuneven adjustment of impeller adjusting bolts

Noise and vibration resulting from the impeller rubbing the suction liner

Adjust the impeller clearance with the pump in the vertical position.

! WARNING Lockout driver power to prevent accidental start-up.

1. Lockout power to driver.

2. Remove the coupling guard (direct drive) or belt guard(belt drive).

3. Break the coupling (direct drive) or remove tensionfrom belts (belt drive).

NOTE: Lubricate the adjusting bolts and nuts for easyturning.

4. Loosen the thrust housing adjusting bolt nuts (415A)and locking capscrews (356B).

5. Turn thrust housing adjusting bolts (9956)counterclockwise to lower the thrust housing (134A)

until the impeller (101) touches the suction liner (600R).

6. Turn the thrust housing adjusting bolts (9956)clockwise to raise the thrust housing (134A) 0.030 in(0.76 mm), which is the recommended operatingclearance. This adjustment is best measured with a dialindicator. Adjust each bolt slightly each time around sothat the thrust housing rises evenly and is not cockedin the bearing frame (228). Make sure the rotatingassembly turns freely throughout the entire rotation.

7. Tighten the thrust housing adjusting bolt nuts (415A)and locking capscrews (356B), carefully noting that

the dial indicator does not change during finaltightening.

8. Make sure the rotating assembly turns freelythroughout the entire rotation.

9. Align the coupling (direct drive) or sheaves (beltdrive) as outlined in the installation section.

10. Replace the coupling guard (direct drive) or belt guard(belt drive).

PUMP WASHDOWNThe pump is designed to prevent liquid from entering the bearing frame. Care should be taken, however, to avoidspraying a high pressure stream directly at the bearingframe seals.

TROUBLESHOOTING GUIDE

MOTOR OVERLOAD Speed too high Total head lower than pump rating resulting in

increased flow Liquid being pumped has higher specific gravity than

that for which it is rated

Mechanical defects: bent shaft, worn bearings, wornimpeller or other wet end parts Solids locked in and around impeller Rubbing or binding of rotating elements

WATER HAMMER Water hammer is a high pressure surge within a closed pipesystem, created by a rapid change in the flowrate. The mostcommon is the sudden opening or closing of a valve or other flow control device. Rapid changes in flowrate canalso occur when there is a sudden change in pump speed.Extensive damage to the pump and pipeline can result fromwater hammer.
