CAUTION
Impermissibly high density of the fluid handled
Motor overload!
▷ Observe the information about fluid density in the data sheet.
▷ Make sure the motor has sufficient power reserves.
6.2.3.3 Abrasive fluids
Do not exceed the maximum permissible solids content specified in the data sheet.
When the pump handles fluids containing abrasive substances, increased wear of the
hydraulic system and shaft seal are to be expected. In this case, reduce the commonly
recommended inspection intervals.
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. (ðSection7.3,Page56)
ü The safety instructions for dismantling the pump have been observed.
(ðSection7.4.1,Page56)
ü 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. (ðSection3.2,Page14)
If the pump set is to be stored temporarily, only preserve the wetted components
made of low-alloy materials. Commercially available preservatives can be used for
this purpose. Observe the manufacturer's instructions for application/removal.
6.4 Returning to service
For returning the equipment to service observe the sections on commissioning/start-
up and the operating limits. (ðSection6.1,Page37) (ðSection6.2,Page46)
In addition, carry out all servicing/maintenance operations before returning the
pump (set) to service. (ðSection7,Page50)
WARNING
Failure to re-install or re-activate protective devices
Risk of injury from moving parts or escaping fluid!
▷ As soon as the work is completed, properly re-install and re-activate any safety-
relevant devices and protective devices.
