2. General description
To ensure reliable and optimum operation, Grundfos
DPK pumps are available with various types of
impellers.
DPK drainage pump:
• 0.75 - 15 kW models have semi-open impeller
• 19 and 22 kW models have closed impeller.
DPK.V wastewater pump:
• 1.5 - 7.5 kW models have Super Vortex free-flow
impeller.
DPK pumps are used for removal of surface and
underground drainage water in buildings, courtyard
drainage systems and industrial applications where
water from various applications is collected into
drainage pits and then pumped further.
DPK.V pumps are used for more applications
including effluent and screened wastewater in similar
applications.
DPK and DPK.V pumps can be controlled via the
pump controllers GU01 and GU02. For further
information, see data sheet for GU01 / GU02 module
at www.grundfos.com.

observance of the hygiene regulations in force.
6. Transportation and storage
6.1 Transportation
The pump can be transported in a vertical or
horizontal position. Make sure that it cannot roll or
fall over.

6.2 Storage
6.2.1 Warehouse storage
• The warehouse must be dry and free from
corrosive gases, vapours or vibrations which
might damage the pump.
• Store the pump in a vertical position on a pallet or
a stand to keep the pump off the floor and
facilitate easy removal.
• Coil up the cable, and seal the open end tightly
with waterproof plastic and tape or a cable cap.
Do this to prevent moisture from penetrating into
the motor which will cause severe damage to the
windings.
• Give all unpainted surfaces a light coat of oil or
grease to prevent corrosion.
• If new pumps are stored for more than two
months, turn the impeller by hand every two
months to prevent the mechanical seal faces
from seizing up. Failure to do this may result in
seal damage when the pump is started up again.
6.2.2 Storage in the tank
• If an installed pump is not in operation for a long
time, check the insulation resistance and run the
pump for 30 minutes every month. If the pump
cannot be run due to lack of water in the tank,
inspect the pump and turn the impeller by hand
each month and prior to putting the pump back
into service. If the insulation resistance drops
below 10 megohms, contact Grundfos.
• When the pump is not in service, disconnect the
power supply from the control panel.
• If the pump is disconnected from the control
panel when not in service, protect the cable end
as described in section 6.2.1 Warehouse
storage.
7. Nameplate
The nameplate is fitted to the top cover of the pump.
Fix the extra nameplate supplied with the pump at
the installation site or keep it in the cover of this
booklet.

10. Installation
Check these points before beginning installation
procedures:
• That the pump correspond to the order.
• That the pump is suitable for the supply voltage
and frequency available at the installation site.
• That the pump, accessories and other equipment
are undamaged during transportation
Prior to installation, check the oil level in the oil
chamber. See section 14. Maintenance, inspection
and overhaul.
The DPK pumps are suitable for different installation
types which are described in sections
10.2 Submerged installation on auto coupling and
10.3 Free-standing submerged installation.
All pump housings can be connected to JIS flange,
hose coupling and auto coupling.
10.1 Installation types
DPK pumps are suitable for two types of installation:
• submerged installation on auto-coupling
• free-standing submerged installation.
10.2 Submerged installation on auto
coupling
Pumps for permanent installation can be mounted on
a stationary auto-coupling guide rail system.
The auto-coupling system facilitates maintenance
and service as the pump can easily be lifted out of
the tank. See fig. 5.
Fig. 5 Submerged pump on auto-coupling
Installation procedure:
1. Fit the guide rail bracket on the inside of the tank
and fasten it provisionally with anchor bolts.
2. Place the auto-coupling base unit on the bottom
of the tank. Use a plumb line to establish the
correct positioning. Fasten with heavy-duty
expansion bolts. Support the auto-coupling base
unit so that it is level when being fastened.
3. Connect the outlet line without exposing it to
distortion or tension.
4. Insert the guide rails in the auto-coupling base
unit and adjust the length of the rails accurately
to the guide rail bracket.
5. Unscrew the provisionally fastened guide rail
bracket and fit it on top of the guide rails.
Fasten the bracket firmly to the tank wall.
Warning
Observe all safety regulations at the
installation site.
Use blowers for fresh-air supply to the
tank.
Warning
Make sure that the lifting bracket is
tightened before attempting to lift the
pump. Tighten if necessary. Carelessness
during lifting or transportation may cause
injury to persons or damage to the pump.
Warning
Before beginning the installation, switch off
the power supply and lock the mains
switch in position 0 with a padlock to
ensure that the power supply cannot be
accidentally switched
on.
Any external voltage connected to the
pump must be switched off before working
on the pump.
Caution
The pumps are designed for operation in
vertical position only.
