2. Installing the product

2.1 Mechanical installation

2.1.1 Pump location

The pump is designed for tank mounting in vertical

position. The pump is positioned in a hole cut into

the cover of the tank (upper side) and is secured to

the tank by four hexagon head screws through the

holes in the mounting flange. We recommend to fit a

sealing gasket between the pump flange and tank.

If the pump is to be installed horizontally, the drain

hole of the motor stool must be fitted with a plug.

Fig. 1

Pump mounting flange dimensions:

2.1.2 Inlet conditions

The bottom of the pump strainer must be at least 25

mm above the bottom of the tank.

The pumps are designed to provide full performance

down to a level of A mm above the bottom of the

strainer.

At a liquid level between A and B mm above the

bottom of the strainer, the built-in priming screw will

protect the pump against dry running.

Fig. 2

WARNING

Moving parts

Death or serious personal injury

- Tighten the coupling screws to the

correct torque.

- Install the coupling guards securely to

the pump with the screws intended for

this purpose.

CAUTION

Hot surface

Minor or moderate personal injury

- The pump must be installed so that

persons cannot accidentally come into

contact with the hot surface of the

motor.

2.2 Electrical connection

The operating voltage and frequency are marked on

the pump nameplate. Please make sure that the

motor is suitable for the power supply on which it will

be used.

Single-phase Grundfos motors incorporate a thermal

overload switch and require no additional motor

protection.

Three-phase motors must be connected to a motor

starter.

The terminal box can be turned to four positions, in

90 ° steps, see fig. 3.

Proceed as follows:

1. Remove the coupling guards. Do not remove the

coupling.

2. Remove the four bolts securing the motor to the

motor stool.

3. Turn the motor to the required position.

4. Replace and tighten the four bolts.

5. Replace the coupling guards.

The electric motor must be connected to the supply

as shown in the diagram inside the terminal box

cover.

Fig. 3

3. Starting up the product

Before starting the pump, make sure:

• that all pipe connections are tight.

• that the pump body is partly filled with liquid

(partly submerged).

• that the strainer is not blocked by impurities.

Start the pump as follows:

1. Close the isolating valve on the outlet side of the

pump.

2. If the pump is fitted with a vent valve, this valve

must be opened, see fig. 4.

Fig. 4

3. See the correct direction of rotation of the pump

on the motor fan cover. When seen from the top,

the pump must rotate counterclockwise.

4. Start the pump and check the direction of

rotation.

5. Open the outlet isolating valve a little.

6. If the pump is fitted with a vent valve, this valve

must be closed when a steady stream of liquid

runs out of it.

7. Completely open the outlet isolating valve.

The pump has now been vented and is ready for

operation.

WARNING

Electric shock

Death or serious personal injury

- Before starting any work on the product,

make sure that the power supply has

been switched off and that it cannot be

accidentally switched on.

- Connect the pump to an external main

switch close to the pump and to a

motor-protective circuit breaker or a

CUE frequency converter. Make sure

you can lock the main switch in OFF

position (isolated). Type and

requirements as specified in EN 60204-

1, 5.3.2.

4. Product introduction

4.1 Applications

The Grundfos pumps, type SPK, are multistage

centrifugal pumps designed for pumping liquids for

machine tools, condensate transfer, liquid transfer in

industrial washing machines and similar

applications.

The pumps are designed for pumping liquids with a

density and viscosity corresponding to those of

water. The pumped liquid must not contain abrasive

particles or fibres.

When pumping liquids with a density or viscosity

higher than that of water, the motor size must be

taken into consideration.

4.2 Identification

The standard range of pumps encompasses

complete impeller-in-chamber combinations.

Depending on duty combinations, other lengths can

on request be supplied by fitting empty intermediate

chambers instead of standard chambers with

impellers.

The pump key on the pump nameplate indicates the

number of chambers and impellers fitted to the

pump.

4.3 Pump key

5. Servicing the product

5.1 Maintaining the product

Pumps installed in accordance with these

instructions require very little maintenance.

The mechanical shaft seal is self-adjusting and has

wear-resistant seal rings which are lubricated and

cooled by the pumped liquid.

The pump bearings are also lubricated by the

pumped liquid. The motor ball bearings are grease

packed and sealed for life. No further lubrication is

necessary.

Pumps from 4 kW and up have angular contact

bearings.

WARNING

Fire and explosion

Death or serious personal injury

- Do not use the pump for flammable,

combustible or explosive liquids.

5.1.1 Filters

Chip trays, filters, etc. must be cleaned at regular

intervals to ensure a correct flow of liquid.

5.1.2 Periodic checks

At regular intervals, depending on the conditions and

time of operation, the following checks should be

made:

• Check the quantity of liquid and operating

pressure.

• Check that there are no leaks.

• Check that the motor is not overheating.

• Check the tripping of the motor starter.

• Check that all controls are operating

satisfactorily.

If the above checks do not reveal any abnormal

operating details, no further checks are necessary.

Should any faults be found, check the symptoms with

section 8. Fault finding the product.
