For combustible fluids: The fluids must not contain any abrasive particles.
6.3 Shutdown/storage/preservation
6.3.1 Measures to be taken for shutdown
The pump (set) remains installed
ü Sufficient fluid is supplied for the functional check run of the pump.
1. For prolonged shutdown periods, start up the pump (set) regularly between
once a month and once every three months for approximately five minutes.
ð This will prevent the formation of deposits within the pump and the pump
intake area.
The pump (set) is removed from the piping and stored
ü
The pump has been properly drained. (

The permissible ambient temperature for storing the pump is observed.
1. Spray-coat the inside wall of the pump casing and, in particular, the impeller
clearance areas with a preservative.
2. Spray the preservative through the suction nozzle and discharge nozzle.
It is advisable to then close the pump nozzles (e.g. with plastic caps).
3. Oil or grease all exposed machined parts and surfaces of the pump (with
silicone-free oil and grease, food-approved if required) to protect them against
corrosion.
Observe the additional instructions on preservation. (
