4. Applications
Grundfos NKF pumps and Fire NKF pump sets are designed for

pumping of liquids or pressure boosting.
The control cabinet must not be used to supply voltage to other
devices.
5. Delivery and storage
5.1 Pump
5.1.1 Delivery
The pumps are delivered from factory in an open or a closed
wooden box designed for transport by forklift truck or a similar
vehicle.

5.1.2 Storage
Apply an antirust agent on all non-coated machined surfaces.
If the pump is to be stored for more than six months before start-
up, the inner pump components must be treated with an antirust
agent.
The antirust agent must meet these requirements:
• It must not attack rubber parts.
• It must be easy to remove.
• It must be applied in accordance with the manufacturer’s
instructions.
In order to prevent water, dust, etc. from entering the pump, all
openings must be covered until pipes are connected. If not, it will
be very expensive to dismantle the pump to remove foreign
matter after installation.
Turn the pump shaft manually once a month to prevent the shaft
seal from seizing up. The driver must be isolated from the pump.
See service instructions for the pump.
5.2 Pump set
5.2.1 Delivery

installed, operated and maintained according to
VdS guidelines. Installation, maintenance and
repair must be carried out by qualified personnel

Warning
The pumps and pump sets must only be used for

Caution
