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.
