6.3 Shutdown/storage/preservation
6.3.1 Measures to be taken for shutdown
The pump ( s e t ) remains ins t a l l ed
✓ Sufficient fluid is supplied for the operation check run of the pump.
1.
Start up the pump (set) regularly once a month or 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 ( s e t ) is removed f r o m the pipe and s t o red
✓ The pump has been properly drained (⇨ Section 7.3 Page 50) and the safety
instructions for dismantling the pump have been observed. (⇨ Section 7.4.1 Page
50)
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 and discharge nozzles.
It is advisable to then close the pump nozzles (e.g. with plastic caps or similar).
3. Oil or grease all blank parts and surfaces of the pump (with silicone-free oil and
grease, food-approved if required) to protect them against corrosion.
Observe any additional information provided. (⇨ 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.
Observe any additional instructions and information provided. (⇨ Section 3 Page 13)
6.3.2 Putting new pumps/pump sets into storage
If commissioning is to take place some time after delivery, we recommend that the
following measures be taken for pump (set) storage:
▪ Store the pump (set) in a dry and protected location.
▪ If properly stored indoors, the pump set is protected for a maximum of 12
months.
New pumps are supplied by our factory duly prepared for storage.
▪ Rotate the shaft by hand once a month.
6.4 Returning to service after storage
For returning the pump to service observe the sections on commissioning/start-up (⇨
Section 6.1 Page 38) and the operating limits (⇨ Section 6.2 Page 43) .
In addition, carry out all servicing/maintenance operations before returning the
pump (set) to service. (⇨ Section 7 Page 46)
WARNING
Failure to re-install or re-activate protective devices
Risk of personal injury from moving parts or escaping fluid!
▷ As soon as the work is complete, re-install and/or re-activate any safety-relevant
and protective devices.
NOTE
If the pump has been out of service for more than one year, replace all elastomer seals.
