General Information:Thank you for purchasing yourHydromatic® self-priming pump. If there are any additional questions not covered in this manual, please contact theHydromatic representative orHydromatic Pump.

Before Operation:Read the following instructionscarefully. Reasonable care andsafe methods should be practicedfor installation and operation ofpump. Check all local codes andrequirements before installation.

Attention:This manual contains importantinformation for the safe use of this product. Read this manualcompletely before using this productand refer to it often for continuedsafe product use. DO NOTTHROW AWAY OR LOSE THISMANUAL. Keep it in a safe placeso that you may refer to it often.

Unpacking Pump:Remove pump from pallet. Whenunpacking unit, check for concealeddamage. Claims for damage mustbe made at the receiving endthrough the delivery carrier.

GeneralInformation

encapsulated windings for moistureprotection. If motor is to operatein the open or in a dusty location atotally enclosed fan cooled motormust be used. If pump is tooperate in a damp location amotor with encapsulated windingshould be used. Motors are to besized so that no overload will existin the operating range of thepump.

Note: When pump units aremounted at the factory, the driver and pump are alignedbefore shipment. During transitand handling of pump and components misalignment mayoccur. Before operation the drivealignment should be checked.

Shaft Couplings:We recommend using Wood’sflexible coupling to prevent misalignment and noise that canbe caused by other couplings. Theextra cost of the coupling is easilysaved in installation and field service that can result from coupling problems.

V-belt drive:Where V-belts are used, keep beltstight by adjusting motor basescrews. Belts should run cool. Ifbelts heat up it will indicate slipping. The V-belts should befiddle string tight.

CAUTION: Belt guards andcoupling guards must be properly installed before operating pump unit.Electrical Starting Equipment:If electrical starting equipment isnot furnished with pump, certainprecautions must be observed inselecting motor starter.

Type of Starter:For three phase power a magneticstarter with 3 leg overload

Damage claims cannot beprocessed from the factory. Checkfor and tighten all loose attachinghardware. Check oil levels andlubricate as necessary.

Do not smoke or use sparkable electrical devices or flames in a septic (gaseous) or possible septic area.Warning: Before handling thesepumps and controls, always disconnect the power first.

Pump Not Operating or in Storage:If pump is not put into serviceimmediately, it must be properlystored to prevent damage. Storeunit in a dry warm location. Neverstore unit in the open even if it isprotected with plastic or othercovering. The bearing housingand motor will draw moisture,which may result in pump failureafter being put in operation.

While in storage pumps with carbon ceramic seals must haveimpellers manually rotated (6 to12 revolutions) after setting non-operational for 3 months orlonger and prior to electrical start-up.

Pumps with tungsten carbide sealsmust have impellers manuallyrotated (6 to 12 revolutions) aftersetting non-operational for 3weeks or longer and prior to electrical start-up.

Motors:Pump unit may be shipped less themotor for customer to supply and mount.

Motor Types:Pumps can be driven by standardopen drip-proof, totally enclosedfan cooled, totally enclosedexplosion-proof or drip-proof with

protection is recommended to prevent motor burnout that canoccur from single phasing ortransformer faults on three-phasesystems. For single-phase motorsa standard starter with 2-leg overloadprotection is recommended.

Electrical:1. For motor overload protection

the magnetic starter trip amprating should not be more than1.25 times the full load ampsof the motor. Hydromatic recommends a rating of 1.15times the full load amps of the motor.

2. Always use fused disconnectswitch or circuit breaker ahead of magnetic starter forshort circuit protection. Whenduplex pumps are used and are operated from single disconnect switch, be sure disconnect switch is largeenough to withstand the starting current of both pumpscoming on at once. This canoccur after a power failure.This is important as a blown fuse or tripped circuitbreaker can make both pumps and an alarm system inoperative, resulting in flooding or other damage.

Ground:Connect a ground wire to motors,control box and other related controls, ground wire to be sizedto the National Electric Code article 250-95. Ground wire mustbe connected to a driven groundstake or to a ground wire from thesupply service. If a ground stakeis used it must be driven at least 8 feet into the ground.

Codes:All local wiring codes must beobserved and any exceptions to

3. To avoid air pockets suctionpipe must be as short anddirect as possible. Suction pipemust always slope upward to the pump from the source ofthe liquid being pumped.

4. The suction pipe should beinstalled at a distance equal to1-1/2 times the diameter of thesuction pipe from the wall ofthe wet well, minimum.

5. The suction pipe should beinstalled at a distance equal toone half the diameter of thesuction pipe or 3" from thefloor of the wet well, minimum.

6. If more than one suction pipeis to be installed in the samewet well, a distance equal to at least 3 times the diameter of the suction pipe should separate them, minimum.

7. Submergence of the suctionpipe is critical to efficient pumpoperations. See the followingchart for the recommended minimum submergence vs.velocity. Submergence may be reduced by installing a standard pipe increaser fittingat the end of the suction pipe.The larger opening size will reduce the inlet velocityand required submergence. SeeFigure 1, page 9.

Vertical Suction Lift:Vertical lift should not be morethan 25 feet. This is for startinglevel only. After pump primes,level can be pumped down to 26to 27 feet if desired, but sumplevel must rise up to the originallevel for restart. All suction linejoints must be airtight as a leak in the suction pipe can causepump to lose prime or not prime at all. Always checkN.P.S.H. calculations for available atmosphere pressure beforeapplying pump.

Pump Installation Foundation:Pump frame or base should beinstalled on a concrete floor withproper shims and grout. Use hardwood tapered shims to driveunder base to level. Base shouldbe about 1 to 1-1/2" off the floor.Build form around the base andfill base inside cavity with grout.Foundation bolts can be set in thegrout or set in the concrete floorwith expansion bolts.

Grout should be made with 1 partcement and 2 parts sand. Mixtureshould be fluid enough to rununder base. Wood shim blocks canbe removed after grout has set andholes filled with quick set cement.

Note: Maximum 5/8" diameterfastener is to be used formounting pump to foundation.

All piping to suction anddischarge openings of pump mustbe supported to remove stressfrom the pump case and bearingframe.

Suction Pipe:1. Suction pipe should be same

size as pump opening. DONOT use larger suction pipe aspriming time will be increasedand velocity may not be highenough to properly carry solids.

2. Pump should be installed asclose to the liquid beingpumped as possible with aminimum of elbows or fittings.

PumpInstallation

Discharge Lines:If the discharge line ends at levellower than the liquid beingpumped, a siphon breaker must beinstalled in the discharge line.Otherwise, siphoning action maycause damage to the pump.

The discharge line should includea system check valve, with outsideweight or spring, to protect thepump from excessive shock pressure and reverse rotationwhen pump is stopped. Do notdepend on the check valve atpump suction to hold dischargepressure. The discharge lineshould include an isolation valve,plug valve or gate valve, to isolatethe pump from the discharge line.This will allow maintenance to be performed on the pump orcheck valve without draining the discharge line.

Air Bleed Pipe:A 3/4" or 1" bleed line with ballvalve or gate valve must beinstalled between the pump discharge flange and dischargecheck valve. The bleed line shouldbe installed as close to thedischarge check valve as possible,end of bleed line to extend a minimum of 6" below low wateroffset point in the wet well. Thevalve in the bleed line is to befully open at initial start-up ofpump. After initial start-up thevalve is to be left partially open atall times. This will allow anytrapped air or gas to be ventedback to the wet well. Be sure ventline is under water at all times.This is important. See installationdrawings. (Figure 2) Self-primingpumps will not compress air toany extent. Pump may not prime if

the bleed line is not used or closedand may not reprime if pumploses prime after the dischargeline is full of water and a discharge check valve is used.

Drain Line from Pump Case:A pipe should be installed in thelower drain tapping of volute caseand be piped back to the wet well.Install a shut-off valve, ball valveor gate valve in this line. This willpermit draining of pump case ifnecessary to remove suction coverto clean impeller or performmaintenance on the pump.

Electrical Connections:Connect power lines to motorfrom magnetic starter. Turn pumpshaft by hand to be sure it is freebefore attempting to start motor.Turn power ON and OFF quicklyto check rotation. If motor is threephase, interchanging any twolines to motor can reverse rotation. If motor is single-phase,consult literature supplied withthe motor for specific instructions.Correct pump rotation is clockwisewhen looking at pulley or couplingend (power end) of pump. Directionarrow is cast on bearing housing.

Priming:For initial prime, remove checkvalve cover cap from suction inletside of pump casing and fill pumphousing with water. Fully openthe air bleed valve in the bleedline. Replace cap, being suregasket is in place and that seat isclean. Start motor and allowsufficient timing for priming.Priming time is dependent onpump speed, impeller diameterand vertical suction lift.

Cleaning Impeller:If impeller gets clogged at anytime, suction cover can be

removed by unscrewing four handknobs or nuts. Remove suctioncover with jacking bolts. Drainpump case before removingsuction cover. Tap on knobs withhammer to loosen. Be sure O-ringgaskets are in place before replacingsuction cover. Use grease onmachined faces to make removaleasier at a later date. Tap on hand knobs with hammer to retighten.

Adjusting Impeller Clearance:Impeller face vanes must be within .015" of suction wear platefor most efficient operation.

When wear plate or impellerwears, it can be readjusted to proper clearance from the outboard bearing end without the use of shims or disturbing thepump case or piping. Loosen thethree screws with the jam nuts.Tighten the other three screwsevenly until the impeller justdrags on the suction wear platewhen the shaft is turned by hand.Back off the three screws andplace a .015 shim under the headof the screw. Turn screw upagainst the shim, then removeshim. Repeat this operation oneach of the three pushing screws.Now retighten the three screwswith jam nuts, pushing thehousing up against the threeadjusting screws. Retighten thejam nuts and pump is ready tooperate with the impeller face.015" from suction wear plate.

This clearance should be checkedat least once a year and more oftenif water-containing abrasives arebeing pumped. When impellerface wear exceeds 1/8", impeller,wear plate and volute lip plateshould be replaced.

WARNING: Before handlingthese pumps and controls,always disconnect the power

screws that hold volute lip plate inplace. Reinstall the lip plate andtighten the screws. Install seal onshaft and place seal spring inplace. Block impeller vane with apiece of hardwood and screwimpeller on by turning pump shaftclockwise. Use a large crescentwrench or strap wrench on shaft, pulling against key to retighten. A pipe wrench can beused if care is used not to damageshaft. Replace impeller lockwasher with pin and stainless lock screw.

The new 6" self-priming pumpuses a taper fit impeller shaft. UsePermatex on the 4 stainless steelscrews that hold volute lip plate inplace. Reinstall the lip plate andtighten the screws. Install seal onshaft and place seal spring inplace, then install key andimpeller. Caution must be taken tobe sure impeller is seated on theshaft and not on the key. Replaceimpeller lock washer and stainless lock bolt.

Replace suction cover with wearplate attached. Check impellerclearance; adjust if necessary as described under adjustinginstructions. Refill seal chamberas described under lubricatinginstructions.

Replacing Inboard Seal:Use all steps outlined underimpeller removal. Slide seal andshaft sleeve from shaft. It may benecessary to tap on sleeve withplastic hammer to loosen. Afterrotating part of seal is removed,use wire hook and pull stationaryseal seat from casting. Wipe sealpocket clean, then install newstationary seat. Use PB Blaster orequivalent on rubber cap and pushin place with fingers, then wipe

to the shaft with a taper fit,remove the stainless steel nut onthe end of shaft, then removewasher. A taper fit shaft can beidentified by the key that drivesthe impeller. To remove impeller,loosen 3 holding screws at outboard bearing cap and tightenup on back-off screws. This willpull the impeller loose from theshaft. After impeller is removed,retighten screws to bring bearingcap back to original position. Itwill be necessary to readjust the impeller clearance after theimpeller is reinstalled. See adjusting instructions.

After impeller is removed,unscrew 3 or 4 stainless steelsocket head screws that holdvolute lip plate in place. Tap onplate to loosen and removethrough volute case inlet opening.The inboard seal now can beremoved for inspection by slidingsleeve from the pump shaft. If the faces are worn, the seal should be replaced. See sealreplacement instructions.

Clean pump casing thoroughly,removing any rust or dirt from allmachined surfaces.

Install lip plate with lip in the oneo’clock position. Use a pipecompound or NEVER-SEEZ®* onall machined faces. NEVER-SEEZ® is a graphite compoundthat will not wash away withwater and is highly recommendedfor all repair work for use onmachine faces. This compound canbe obtained from HydromaticPump if not available at localsupply houses.

The following pertains to the new 4" self-priming pump. UsePermatex®* on the 3 stainless steel

can run quite hot to the handwithout damage to the bearing.Outside temperature of thehousing should not exceed 130° Ffor long bearing life. WARNING: Before handling

these pumps and controls,always disconnect the powerfirst. Do not smoke or usesparkable electrical devices orflames in a septic (gaseous) orpossible septic area. Be sure all belt guards and exposed coupling guards are in placebefore operating unit.WARNING: If the pump hasoverheated, allow pump to coolbefore servicing. Do not removeplates, cover, gauges or fittingsfrom an overheated pump.Liquid inside the pump case canreach the boiling point, andvapor pressure within the pumpcase may cause parts to be ejected with great force. Drainpump case only after pump has been allowed to cool. Usecare to prevent personnel fromtouching the hot liquid.

Pump will not prime:1. Pump discharge does not have

air bleed line installed. Seepump installation instructionsfor air bleed line.

2. Vertical suction lift is too high.Vertical lift for priming shouldnot be more than 20 feet.

3. Allow sufficient time for priming. On high lifts and atlow pump speeds priming timemay take 5 minutes or longer.

4. Suction line has an air leak.Install a vacuum gauge atpump suction flange and startpump. After a vacuum isestablished, stop pump and seeif gauge holds. If gauge handdrops, it will indicate an airleak at some connection belowthe gauge tap.

5. Check pump rotation. Pumpmust turn clockwise when lookingat the power end of pump.

6. Not enough liquid in pumpcasing. Add water to the case.Pump needs water in the pumpcase to prime.

7. Suction check valve damagedor contaminated. Replace check valve.

8. Leaking or worn seal or pumpgasket. Check pump case vacuum, replace leaking orworn seals or gaskets.

Pump primed OK initially butoccasionally loses prime andwill not reprime without addingwater:

IMPORTANT: Drain pumpcase and close discharge gatevalve before removing inspectioncover.

1. Air bleed line is not installedproperly as specified or is plugged.See installation instructions.

2. Check priming port for plugging. Remove inspectioncover on right side of casewhen facing power end ofpump. Check priming porthole in case below inspectionplate for plugging.

3. Impeller may be worn, leavingtoo much clearance betweenimpeller face and suction wear plate. Adjust impeller as described under adjustinginstructions. If impeller andvolute lip plate are worn, theymust be replaced to regainoriginal priming efficiency.

PumpTroubleshooting

PumpShaft Seals

Shaft Seals:Hydromatic has introduced a newsingle shaft seal self-primingpump model and new dual shaftseal self-priming pump model.The oil cavity is accessible forfilling and draining of the oil cavity from the exterior of thevolute casing. See page 12 fordiagram of the 4" pump and page14 for a diagram of the 6" pump.The oil in the seal chamber shouldbe checked every six months orevery three months if water-containing abrasives are beingpumped. Remove hex head plugfrom top of seal chamber andloosen hex plug at bottom of sealchamber. Place a container underthe lower plug then remove lowerplug and allow oil to drain intocontainer. After all oil is removed,pour used oil into a glass containerso that it can be observed. If theoil is clean it will indicate sealsare in good condition. If a smallamount of water shows in the oil,this will also indicate satisfactoryseal operation. If considerablewater and some dirt shows in theoil, it will indicate the inboardseal is worn and should bereplaced before outboard seal isdamaged. If seals are in goodorder, refill the seal chamber with#30 non-detergent automotive oil.About 2-1/2 quarts are required.Fill with funnel or tube so that theair can escape. Oil chamber must have a 1" air gap; do not overfill oil chamber.

PumpTroubleshooting

Pump makes a loud cracklingnoise when operating:1. If pump has been operating

satisfactorily and this noisesuddenly starts, it may indicatethat some large object islodged in the suction checkvalve, suction cover/plate orimpeller causing the pump tobe noisy. Remove debris fromthese areas of the pump.

2. If noise exists when suctionpipe, check valve and suctioncover port are clear, it mayindicate too high a capacitybeing delivered for a givensuction lift, causing suctioncavitation. If pump is allowedto operate under theseconditions, the impeller will bedamaged. Using a smallerimpeller or reducing the pump speed if a belt drive isused may alleviate thecavitation. Consult factory forrecommendations.

3. If cracking noise is pronouncedwhen pump is operating at lowcapacity it may indicate pumpis operating too near the shut-offhead. Increasing the impellerdiameter or increasing pumpspeed may alleviate this condition. Consult factory forrecommendations.

4. Performance curves show maximum / minimum capacitythat the pump will deliver at agiven condition point and theallowable suction lift withoutcavitation. Use vacuum gaugeat pump suction to check totalsuction lift when pump is operating. Use discharge pressure gauge at pump discharge to check dischargehead. Total the two-gauge

reading to determine the totaldynamic head the pump mustoperate against.

5. Entrained air may be presentand is being pumped. Findsource of air and eliminate.

6. Pump or drive is notsecurely mounted. Retightenall components.

Pump does not deliver ratedcapacity:1. Total head may be higher than

calculated. Pump capacity isbased on total head. Totaldynamic head is arrived at byadding the suction gauge reading,in feet, to the discharge gauge reading, in feet. These readings should be taken at thesuction flange and at the pumpdischarge flange connections.Reading should be taken asclose to the flange fittings andpump case as possible. To convert psi, pressure persquare inch, to feet, multiplythe total psi readings by 2.31.This will equal total dynamichead in feet.

2. Pump impeller may be wornon the vane faces or the clearance between the impellerand wear plate may be greaterthan .015". Adjust impeller towear plate clearances for proper clearance as describedunder adjusting instructions. Ifimpeller, suction wear plateand volute lip plate are badlyworn they must be replaced.

3. Pump speed may be too slow.Check drive assembly, V-beltsor coupling, for slippage.

4. Possible air leak in the suctionpiping. Eliminate the leak.

5. Suction head may be too high.Reduce lift by raising on/offlevels in the wet well or reducefriction losses due to suctionpiping arrangement.

6. Suction line not submerged atproper levels. Correct suctionpipe submergence.

7. Blockage in the suction pipe or discharge pipe. Remove blockage. Where the blockageis can be determined by gauge readings.

8. Impeller clogged; remove debris.

Motor starter overload tripsafter pump has operated for ashort period:1. Rags or trash may be caught

in the impeller causing extra load. Remove suctioncover/plate and clean impeller.Pump shaft must turn freely byhand after cleaning impeller.

2. Overload heater may be toosmall. Check heater size withfull load amps of motor. See anelectrical table for proper size.

3. Total head may be lower thancalculated, causing extra loadon the motor. Reducingimpeller diameter or reducingspeed, if belt driven, will lowermotor load. Consult factory forrecommendations.

4. Pump may be pumping a liquidheavier than water or a liquidwith higher viscosity thanwater, such as heavy oil.Consult factory for powerrequired to pump oils or liquids other than water.

5. Bearings may be damagedcausing excessive motor load.

6. Pump speed may be too high.Check drive output to see ifthey are sized properly.

Pump clogs frequently:1. Liquid solution being pumped

is too thick. Dilute if possible.

2. Discharge velocity too slow.Open discharge valves to fullyopen; increase pump speed.

9

Bearing running too hot:1. Drive misaligned; realign drive.

2. Low or incorrect lubricant. Useproper type and level of lubricant.

3. Suction and/or discharge pipenot supported properly. Checkpiping installation for propersupport; take strain off thepump case and bearing frame.
