The pumps are ideal for pumping the above liquids
from installations in or near these places:
• commercial buildings
• residential buildings
• courtyards
• farms
• industries
• underground car parks.
The pumps are suitable for both permanent and
temporary installation.

5. Safety

Warning
Pump installation in tanks must be
carried out by specially trained
persons.
Work in or near tanks must be carried
out according to local regulations.
All persons involved must wear appropriate personal
protective equipment and clothing, and all work on
and near the pump must be carried out under strict
observance of the hygiene regulations in force.

6. Transportation and storage

The pump can be transported in a vertical or
horizontal position. Make sure that it cannot roll or
fall over.
Always lift the pump by its lifting bracket, never by
the motor cable or the hose/pipe.

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.
