Putting out of operation

8.1

Putting out of operation temporarily

With this type of switch-off, the pump remains installed and is not disconnected from the mains power supply. When
out of operation temporarily, the pump must remain completely submersed so that it is protected from frost and
ice. It must be guaranteed that the service room and pumping medium do not freeze completely. The pump is then
ready for operation at any time. Following longer periods of standstill, a 5-minute function run should be carried out
at regular intervals (once a month to once every three months).
Caution!
A functional run may only take place under valid operating and usage conditions. Dry running is not permitted.
Disregarding these facts can lead to total failure.
8.2

Putting out of operation finally/ putting in storage

Switch off the system, disconnect the pump from the mains power supply and put it in storage. The following points
must be taken into particular consideration for the storage procedure:
Beware of hot parts!
Watch the temperature of the housing parts when removing the pump. These can be far above 40°C. Always allow
the pump to cool to ambient temperature first.
• Clean the pump.
• Store in a clean and dry location, protect the pump from frost.
• Set down vertically on a firm base and secure it from falling over.
• Seal the discharge and intake connection with suitable aids (e.g. film).
• Support the electrical connection cable at the cable ducts to prevent permanent deformation.
• Protect the ends of the power supply cables to prevent humidity penetration.
• Protect the pump from direct sunlight to prevent the danger of elastomer parts and housing coating becoming
brittle.
• When storing in a workshop, heed the following: The radiation and gases which occur during electro-welding
destroy the elastomers of the seals.
• During longer storage periods, the impeller or the propeller must be turned regularly by hand (every six months).
This prevents pressure marks in the bearings and seizure of the rotor.
8.3

Putting back into service after longer periods of storage

Before it is put back into service, the pump must be cleaned of dust and oil deposits. Then all the necessary
maintenance measures and work must be carried out (see chapter "Regular maintenance"). The floating-ring type
shaft seal must be checked for proper condition and function. When this work is finished, the pump can be installed
(see chapter "Set-up") and connected to the mains power supply by a specialist. Follow the instructions in the
chapter "Putting into operation" when putting the machine back into operation.
The pump may only be switched on again if it is in a perfect condition and ready for operation.
