InstallationPump installationRun the cables so that they do not have any

sharp bends and are not pinched.Connect the discharge connection and motorcable. See Electrical connections.

Lower the pump into the sump.

Place the pump on a base which will prevent itfrom sinking into a soft sump bottom. Alternati-vely, the pump can be suspended by its liftinghandle just above the sump bottom.

NOTE!Where required by local au-

thorities an acceptable motor-circuit switch or other discon-

necting device shall be provid-

ed at the time of installation.

NOTE!At certain installations and

operation points on the pump

curve the noise level 70 dB,

noise level specied for theactual pump, can be exceeded.

Transportation and storageThe pump may be transported and stored in a

vertical or horizontal position. Make sure that itcannot roll or fall over.

WARNING!Always lift the pump by its

carrying handle or lifting eyes,

never by the motor cable or

the hose.

WARNING!Before starting to work on thepump or moving the pump,

make sure that the pump is

isolated from the power sup-

ply and cannot be energized.

This applies to the control cir-

cuit as well.

The pump is frostproof as long as it is operating

or is immersed in the liquid. If the pump is takenup when the temperature is below freezing, theimpeller may freeze. The pump shall be operatedfor a short period after being taken up in orderto expel all remaining water.

A frozen impeller can be thawed by allowing thepump to stand immersed in the liquid for a shortperiod before it is started. Never use a nakedame to thaw the pump.

For longer periods of storage, the pump must beprotected against moisture and heat. The impel-

ler should be rotated by hand occasionally (forexample every other month) to prevent the sealsfrom sticking together. If the pump is stored formore than 6 months, this rotation is mandatory.

After a long period of storage, the pump shouldbe inspected before it is put into operation. Payspecial attention to the seals and the cable entry.

Follow the instructions under the heading Be-fore starting

WARNING!

Make sure that the pump can-not roll or fall over and injure

people or damage property

Electrical connectionsAll electrical work shall be carried out under the

supervision of an authorized electrician.

Local codes and regulations shall be compliedwith.

Check that the mains voltage and frequencyagree with the specications on the pump dataplate.

NOTE! For safety reasons, the earth (ground)lead should be approx. 200 mm (7.9 in) longerthan the phase and monitoring leads. If the mo-tor cable is jerked loose by mistake, the earth(ground) lead should be the last lead to come

loose from its terminal. This applies to both endsof the cable.

Make sure that the pump is correctly earthed(grounded).

When the pump is connected to the public mainsit may cause icker of incandescent lamps whenstarting. In this case the supply authority shouldbe notied before installing the pump.

WARNING!All electrical equipment must

be earthed (grounded). This

applies to both pump equip-

ment and any monitoring

equipment. Failure to heed

this warning may cause a le-

thal accident. Make sure that

the earth (ground) lead is cor-

rectly connected by testing it.

NOTE!Make sure that the monitoring

equipment incorporated in the

product is correctly connected

and in use.

WARNING!If the pump is equipped with

automatic level control or con-

tactor unit, there is a risk of

sudden restart.

WARNING!Bear in mind the risk of elec-

trical shock if the electrical

connections are not correctly

carried out or if there is fault

or damage on the pump.

WARNING!If persons are likely tocome into physical contactwith the pump or pumpedmedia (liquid), e.g on con-struction sites and farms,the earthed (grounded)socket must have an addi-tional earth(ground-) faultprotection device (GFI)connected.

WARNING!When pumping near a lake

(jetties, beaches, ponds,fountains etc) a safety-dis-tance of at least 20 m (65ft) between the person andthe pump is applicable. Thepump must never be placeddirectly into a swim mingpool. If used in connectionwith swimming pools, spe-cial safety regulations ap-ply.

OperationBefore startingCheck the oil level in the oil casing.Remove the fuses or open the circuit breakerand check that the impeller can be rotated byhand.Check that the monitoring equipment (if any)works.The impeller shall rotate clockwise, as viewedfrom above. When started, the pump will jerk inthe opposite direction to the direction in whichthe impeller rotates. See the gure.

Starting jerk

WARNING!Always lift the pump by its

carrying handle or lifting eyes,

never by the motor cable or

the hose.

CleaningIf the pump has been running in very dirty wa-ter, let it run for a while in clean water, or ushit through the discharge connection. If clay,cement or other similar dirt is left in the pump itmay clog the impeller and seal, preventing thepump from working.During a longer period out of operation, thepump must be test run every other month toprevent the mechanical seals from sticking to-gether.

WARNING!Watch out for the starting jerk,

which can be powerful.

Care and maintenanceSafety precautions Inspection

Regular inspection and preventive maintenanceensure more reliable operation.

The pump should be inspected at least twice ayear, more frequently under severe operatingconditions.

Under normal operating conditions, the pumpshould have a major overhaul in a service shoponce a year.

This requires special tools and should be done byan authorized service shop.

When the pump is new or when the seals havebeen replaced, inspection is recommended afterone week of operation.

WARNING!Before starting to work on the

pump or moving the pump,

make sure that the pump is

isolated from the power sup-

ply and cannot be energized.

This applies to the control cir-

cuit as well.

WARNING!If the seal leaks, the oil casing may be under pressure.

Hold a rag over the oil casing screw in order to prevent

splatter. See Safety precautions for additional informa-tion.

WARNING!If there has been leakage, the stator casing may be un-

der pressure. Hold a rag over the inspection screw to

prevent splatter. See Safety precautions for additional

information.

Lay the pump on its side.Tilt the pump so that any liquid in the inspection chamber can run outthrough the hole.If there is water in the stator casing, the cause may be: that the inspection screw is not sufciently tight. that the O-ring on the inspection screw or its sealing surface is dam

aged. that an O-ring is damaged. that the cable entry is leaking.

If there is oil in the inspections chamber, the cause may be: that the inner mechanical seal is damaged. Contact a Grindex serv

ice shop.

Replace or x worn and damaged parts.Make sure that all screws, bolts and nuts are tight.

Replace worn parts if they impair function.

A check of the condition of the oil can show whether there has been anincreased leakage. Note! Air/oil mixture can be confused with water/oilmixture.Insert a tube (or hose) into the oil hole. Cover the top end of the tube andtake up a little oil from the bottom.Change the oil if it contains too much water.

See Changing the oil. Check again one week after changing the oil.If the oil contains too much water again, the fault may be: that an oil screw is not sufciently tight. that the O-ring on an oil screw or its sealing surface is damaged. that the mechanical seal is damaged. Contact a Grindex service

shop.

Explanation of symbols

= Oil screw

= Inspection plug

It is easier to drain the oil if the other oil screwis also removed.

Fill up with new oil.

A parafn oil with viscosity close to ISO VG32 isrecommended. The pump is delivered from fac-tory with this type of oil.

In applications where poisonous properties areof less concern, a mineral oil with viscosity up to

ISO VG32 can be used.Always replace the O-rings on the oil screws. Putthe screws back and tighten them.

Changing the oil

Lift the pump horizontally with an overheadcrane and place on relief table.Turn the pump so that one of the oil screws

faces downwards. Lock the pump with a supportpreventing it from rolling over.Unscrew the oil screw.

Mount the cover with its O-ring.Tighten the screws, tightening torque 76 Nm(57 lbf-ft).Make sure that the impeller rotates freely. If not,the adjustment screw and the conical sleeve hasnot been aligned and the shaft might have beendisplaced relative to the main bearing!

Before assembly, check that the impeller screwis clean and easy to screw into the shaft end(a). This to prevent the shaft to rotate with theimpeller screw. Assemble the conical sleeve andthe impeller onto the shaft.

Installing the impeller and

setting clearance

Make sure that the end of the shaft is clean andfree from burrs. Polish off any aws with neemery cloth. Grease end of shaft, conical sleeveand the threads of the adjustment screw. Theproper lubrication is grease for bearings e.g.Exxon Mobile Unirex N3 or equivalent.

NOTE!Remove surplus grease from conical and cy-

lindrical surfaces of the shaft and the sleeve

thoroughly.

Align the edge of the adjustment screw with theedge of the conical sleeve so that they are ush.Grease the threads of the screw and the washer.The proper lubrication of the screw and washeris lubricating grease for assembly of bolts etc.e.g. Kluber ALTEMP Q NB 50 or equivalent.

Mount the strainer and the nuts,tightening torque 44 Nm (32.5 Lbf ft).

N H

Turn the adjustment screw clockwise until theimpeller makes contact with the suction cover.Tighten it further 1/8 turn, 45o . This will ensurethe correct clearance between the impeller and

the suction cover in the next step.

Lock the impeller with a screw driver or similar(L= min. 200 mm/7.9 inch), see g. to preventrotation of the impeller. Fit the washer and thegreased impeller screw and tighten, torque to 76Nm (57 lbf-ft).

Check that the impeller rotates freely.

When changing an impeller or after service, werecommend that the screw is rst tightened tothe prescribed torque and then turned an addi-tional 1/8 ( 45) of a revolution. The screw willbe loaded to its yield point and the load capacityof the jonit will be higher.
