RECEIVING and INSPECTION4. Pump suction and discharge ports must becovered to prevent foreign material fromgetting into the pump and causing damagewhen pump is started at a later date.Gusher Pumps, Inc. has taken great care inpreparing your pump for shipment, however,due to circumstances beyond our control, yourshipment may be received damaged. Therefore, we strongly recommend that you take afew minutes to check your pump upon receipt.Check for cracked, bent, severely misaligned(minor misalignments almost always occurduring shipment), or even missing parts. If anysuch damage has occurred, you must report itto the delivering carrier and Gusher Pumps, Inc.immediately.5. Pump must be stored in a dry location.6. Rotate pump shaft several times every othermonth.Handling! WARNING !Pump and components are heavy. Seriousphysical injury or damage to equipmentcould occur from failure to properly lift andsupport pump. Steel-toed shoes must beworn at all times.We also recommend that you check the modelnumber, horsepower, current characteristics,g.p.m., and ft. head of pump received to ensure that you have received the pump you ordered for your specific operating conditions. Ifyou should find some discrepancy, report it toGusher at once.Use care when moving pumps. Lifting equipment must be able to sufficiently support theentire pump. Refer to Figs. 2a, b, c for properlifting techniques.StorageIf your pump is not going to be installed withinsix months, several precautions must be taken;1. Preservative treatment of bearings and machined surfaces is required.2. Remove packing on pumps with packedstuffing box, the stuffing box and shaftsleeve must be oil lubricated to also protectagainst moisture.3. Units equipped with mechanical seals mustalso be oil lubricated with an oil can throughthe NPT port while rotating the shaft byhand.6

Theball bearing housing must then be thoroughlycleaned with kerosene or carbon tetrachlorideand relubricated. On packed pumps, it will benecessary to clean the shaft sleeve and stuffingbox with kerosene or carbon tetrachloride andthen repack.When preparing your pump for installation,the discharge and suction ports must be cleanand free of anything that might prohibit a tightconnection. This is especially important on thesuction, air leaks can cause a pump to operatepoorly or to lose prime completely.LOCATION/FOUNDATIONWhenever possible locate pump far enough below the minimum liquid level in the reservoir sothere will be a positive head on the suction atall times. Where this is not possible, the pumpshould be located as near the source of supplyas possible. Allow ample room for inspectionand maintenance. Baseplate mounted pumpsare usually grouted on a concrete foundationthat has been poured on a solid footing. Thefoundation should be of heavy construction to7
reduce vibration and must be rigid enough toresist the torque it may be subjected to. Thefoundation should be 2” to 6” larger than thebase, depending on the size of the base. Aspace of approximately 2” should be left between the foundation and the bottom of thebase for grouting. Use a pipe sleeved bolt (Fig.3) to within 1/2” of the base for a foundationbolt.LEVEL BASEPLATEFab. Steel3. Level baseplate to within 1/8” over thelength and to within .088 in. over the widthby adjusting the wedges.It should be noted at this time that SPECIALCARE must be taken when leveling your pumpfor alignment, it is of the utmost importance.Once the pump is set the only means of adjusting is by shimming.4. Hand tighten bolts.1. Place 12 wedges on the foundation, onewedge on each side of every mounting bolt.Place wedges so that baseplate is 3/4”above foundation to allow for adequategrouting (Fig. 4).2. Carefully lower the baseplate onto mounting bolts.8
1. Coat all jack screws with an anti-seizingcompound to allow for easy removal afterthe grout has cured.6. Turn down the center jack screws until theyare resting on their metal plates.7. Move the two levels to the pump pads.Place one level lengthwise on a single pad,and the other across the middle of bothpump pads.2. Cut 6 round plates from barstock to set thejack screws on. Chamfering the edges ofthe plate is recommended to reduce stressconcentrations.8. Adjust the jack screws to level the pumppads in both directions.3. Set the baseplate on the foundation, thenraise it 3/4” to 1 1/2” using the four cornerjack screws. At this time, the two centerjack screws should not be touching thefoundation.9. Install the anchor bolts until they are handtight.10. Recheck the motor pads for level measurements.4. Place one machinist level lengthwise on asingle motor pad, and another across theends of both motor pads. (It is importantthat the surface being leveled is free of allcontaminants, such as dust, to ensure thatyour reading is accurate.)11. Continue adjusting the jackscrews and anchor bolts until all level measurements arewithin the requirement of 0.002 on in./ft.5. Adjust the four jack screws in order to levelthe motor pads to zero in both directions.COUPLING ALIGNMENT PROCEDURE Before grouting baseplate to make certainalignment can be obtained! WARNING !Before starting any alignment procedure,ensure that the motor power is lockedout. Failure to do this will result in seriousphysical injury. After grouting baseplate to make sure nochanges have occurred. After connecting piping to ensure that alignment hasn’t been altered by pipe strain. Ifalignment has changed alter piping to remove strain.For trouble-free operation of this unit, properalignment must be attained. Proper alignmentis the responsibility of the installer and user ofthis pump.Final Alignment (Hot Alignment) After first run to obtain correct alignmentwhen equipment is at operating temperature.Alignment ChecksInitial Alignment (Cold Alignment)9
Alignment CriteriaGood alignment is achieved when the differences between the readings is .010 or less whenthe pump is at operating temperature. However, during the installation phase it is necessary to set the parallel alignment in the verticaldirection to a different criteria. This is due to thedifferences in the expansion rates of the pumpand the motor. The recommended cold settingsfor electric motor driven pumps is shown in Table 1.Angular AlignmentCheck angular alignment with a micrometer orcaliper. Measure from the outside of one flangeto the outside of the other flange at intervalsaround the periphery of the coupling, DO NOTrotate the coupling. The difference between themaximum and the minimum must not exceed.010”.Parallel AlignmentCheck parallel alignment by placing a straightedge across the two coupling flanges and measure the offset at various points around theperiphery of the coupling. DO NOT rotate thecoupling. If offset exceeds .010” realign thecoupling.TABLE 1COLD SETTING OF PARALLELVERTICAL ALIGNMENTPumpage Temperature Set Driver Shaft50OF (10OC).002 in.

GROUT BASEPLATE1. Clean the areas on the baseplate that willcontact grout. Do not use oil-based cleaners because the grout will not bond to it.3. Pour grout into form being sure that it flowsunder the base. Fill to within 3/4” to 1” fromthe bottom of the base.2. Build a form around the base as illustratedin Fig. 5. Then thoroughly wet the foundation.4. Allow grout to set for 48 hours.5. Recheck coupling alignment, make any adjustments that may be necessary and tighten foundation bolts securely.PIPING! WARNING !Guidelines for piping are given in the “HydraulicInstitute Standards” available from the Hydraulic Institute, 30200 Detroit Road, Cleveland, OH44145-1967 and must be reviewed before installing pump.Never force piping into position by pullingit in place with the pump suction and discharge flange bolts. This will cause misalignment between pump and driver whichwill adversely effect the operation of theunit resulting in physical injury and damage to the equipment.1. All piping must be supported independentlyof the pump.11
2. Before connecting the piping to the pump,ensure that grout has hardened and thefoundation bolts have been tightened.4. When using a strainer on the suction, installit as close to the pump as possible and select a strainer with a net area of at least fourtimes that of the suction pipe.3. When handling liquids at high temperatures,it is recommended that expansion loops orjoints be properly installed in suction and/ordischarge lines so that linear expansion ofpiping will not draw pump out of alignment.5. Whenever possible the end of the suctionshould be a minimum of 3’ below the liquidlevel (Fig 6). The liquid near the pump suction should be free from agitation to preventair entering the suction line.4. On pumps handling corrosive liquids, thepiping should be arranged to allow for flushing prior to removal.6. Liquid coming back into the reservoir shouldnot enter near the pump suction pipe, andthe liquid should not drop from a high level(Fig. 6).5. Clean all pipe parts prior to installation.Suction Piping ! WARNING !7. If a foot valve is not used in the suction line,it is good practice to bell out the suctionpipe to lower the entrance velocities at theinlet (Fig. 6).NPSHA must always exceed NPSHR asshown on Gusher performance curves.Reference Hydraulic Institute for NPSHand pipe friction values needed to evaluate suction piping.Properly installed suction piping is necessaryfor trouble-free pump operation. Flush suctionpiping before connection to the pump.1. Never place a pipe line elbow in the horizontal plane directly at the pump suction. Use astraight pipe four to six pipe diameters longbetween the elbow and the pump suction.2. Use suction pipe one or two sizes largerthan the pump suction, with an eccentricreducer, sloping side down, at the suctionflange (Fig. 7). Suction piping should neverbe smaller than the pump suction.Suction Lift Conditions3. Never throttle pump on the suction side, always control flow by throttling on the discharge side of the pump.3. All connections must be air tight.1. Pipe must be free from air pockets.2. Pipe must slope upwards to pump.12
4. Whenever possible avoid dynamic suctionlifts of more than 15’.is required to prevent pump or seal damagefrom reverse flow through the pump whenthe motor is turned off.5. A means of priming the pump must be provided.2. Discharge pipe increasers should be connected between the pump and the checkvalve (Fig.7).Suction Head/Suction Conditions3. If quick closing valves are installed in thesystem, cushioning devices should also beinstalled to protect the pump from surgesand water hammer.1. An isolation valve should be installed in thesuction pipe at least four diameters from thesuction to allow closing of the line for pumpinspection and maintenance.2. Pipe must be free from air pockets.3. Piping should be level or slope graduallydownward from the source.4. No part of the piping should extend belowpump suction flange.5. The size of the entrance from the supplyshould be one or two sizes larger than thepipe.6. To prevent vortices and air entrainment atthe supply, the entrance from the supplymust be adequately submerged below theliquid surface.Final Piping CheckDischarge PipingAfter all piping connections have been made tothe pump:1. A gate valve and check valve should be installed in the discharge line. The check valveshould be installed between the gate valveand the pump (Fig 7) this will allow for inspection of the check valve. The gate valve isrequired for priming, flow regulation, and formaintenance of the pump. The check valve1. Rotate the shaft by hand to ensure that thereis no binding and all parts are free.2. Recheck pump alignment to detect any pipestrain, if pipe strain exists correct piping.13

When pumping liquids under 200OF (93OC),the impeller front clearance for the S, M, and Lis between .010” and .015”. If the impeller frontclearance is not set between the above valuessignificant performance degradation will result.When pumping liquids above 200OF (93OC) thefront impeller clearance when cold must be setper Table 2. This is necessary to allow for differential expansion due to the higher operatingtemperature. See the Maintenance section forcorrect impeller adjustment procedure.1. Wire motor according to motor manufacture’s specifications and according to stateand local regulations.2. Lock out power to driver3. Disconnect motor/pump shaft coupling toprevent dry operation of the pump and reverse rotation.!

Couple Pump and Motorto fill the discharge pipe several feet abovethe pump discharge.1. Lock out power to motor to prevent accidental rotation and physical injury.3. After filling pipe and pump close air vent.2. Install and lubricate coupling per manufacturer’s instructions.4. The pump will remain primed unless the footvalve leaks or if the liquid is contaminatedand does not allow foot valve to close tight.3. Install coupling guard (see Appendix 3 Coupling Guard Installation instructions).With an ejector:! WARNING !1. Mount ejector at the highest point in the impeller housing to ensure removal of all the airin the casing and suction pipe.Never operate a pump without the couplingguard properly installed. Personal injurycan occur if pump is run without coupling2. Operate ejector with gate valve in dischargeline closed.guard.Prime Pump3. Operate until ejector discharges a full steadyflow of liquid.No centrifugal pump will operate satisfactorilyuntil it has been properly primed. Do not attempt to prime pump when operating and DONOT under any circumstances operate thepump without being completely primed. Someof the most common methods of priming areflooded suction, foot valve in suction line, ejector (steam, water, or air operated), and vacuumpump.4. On pumps using packing it may be necessary to tighten packing gland to preventpulling of air through shaft clearances. After pump is primed properly loosen glandto achieve a slight trickle of liquid throughstuffing box.With a vacuum pump:With flooded suction:1. Slowly open the gate valve in the suctionline.1. Mount vacuum pump at the highest point inthe impeller housing to ensure removal of allthe air in the casing and suction pipe.2. Remove the air vent in the top of the pumpcasing to release entrained air.2. Gate valve in discharge line must beclosed.3. Close the air vent once liquid starts to flowout of it.3. After pump is primed, valves betweenvacuum pump and Gusher pump must beclosed.With foot valve in suction line:4. On pumps using packing it may be necessary to tighten packing gland to preventpulling of air through shaft clearances. After pump is primed properly loosen glandto achieve a slight trickle of liquid throughstuffing box.1. Open air vent on pump casing.2. The pump and suction line must be filled withthe liquid being pumped. It is recommended15
INITIAL STARTING1. The gate valve in the discharge line shouldbe closed and gradually opened as themotor reaches full speed (approximately 5to 10 seconds). After the pump has beenin operation and the suction and dischargelines are filled with liquid, it is not necessaryto close the gate valve when starting.3. If your pump is packed, loosen packinggland screws to allow free leakage. Thentighten screws uniformly on packing glanduntil leakage is reduced to approximately30 drops per minute. Never tighten packingenough to stop all leakage, a slight leakageis required to lubricate packing and preventscoring of shaft sleeve.2. Start motor and immediately observe pressure gauges. If discharge pressure is notquickly attained stop pump, reprime, andattempt to restart.4. Check pump for vibration levels, bearingtemperature, and excessive noise. If normallevels are exceeded, shut down and investigate.OPERATIONAlways vary the capacity with gate valve in thedischarge line. Never restrict intake flow.! WARNING !DO NOT operate pump below minimumrated flows or with suction or dischargevalves closed. These conditions could create an explosive hazard due to vaporization or pumpage and can quickly lead topump failure and physical injury.If the specific gravity of liquid being pumped isgreater than originally assumed or if the ratedflow is exceeded, the motor may overload.To prevent damage from cavitation or recirculation, always operate pump at or near the ratedconditions.Drain all liquid from inside pump if it will beexposed to freezing conditions while idle. Theconditions could cause liquid to freeze anddamage the pump. Liquid inside cooling coils,if supplied, should also be drained.FINAL ALIGNMENT1. Run the unit under actual operating conditions long enough for the pump and motorto reach operating temperature.2. Check alignment while unit is still hot.3. Make any necessary adjustments and reinstall the coupling guards.16
