6.8.2. Density of fluid handled
The pump input power changes in proportion to the density of the fluid handled.
CAUTION
RISK OF PROPERTY DAMAGE!
Too high density of the fluid pumped could lead to motor overload, which could damage
the motor.
Observe the density information in the order documentation.
Make sure that the motor has sufficient power reserves.
6.8.3. Abrasive fluids
Do not exceed the maximum permissible solids content specified in the order documentation.
When the pump handles fluids containing abrasive substances, increased wear of the hydraulic
system and the shaft seal are to be expected. In this case, reduce the commonly recommended
inspection intervals.
6.9. Decommissioning / out of service
When the pump is decommissioned or put out of service for a longer period of time, it has to be
stored properly.
The pump (set) remains installed
Sufficient fluid is supplied for the operation check run of the pump.
1. Start up the pump (set) regularly between once a month and once every three months for
approximately five minutes during prolonged shutdown periods. This will prevent the formation
of deposits within the pump and the pump intake area.
The pump (set) is removed from the pipe and stored
The pump was properly drained and the safety instructions for dismantling the pump was
observed.
1. Spray-coat the inside wall of the pumpcasing, and in particular the impeller clearance areas,
with a preservative.
2. Spray the preservative through the suction and discharge nozzles. It is recommended to close
the pump nozzles (e.g. with plastic caps or similar).
