6.3 Shutdown/storage/preservation
6.3.1 Measures to be taken for shutdown
The pump (set) remains installed
✓
Sufficient fluid is supplied for the operation check run of the pump.
✓
The fluid does not change during pump shutdown (e.g. freeze or polymerise).
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 (set) is removed from the pipe and stored
✓
The pump has been properly drained (
⇨
Section 7.3 Page 38) and the safety
instructions for dismantling the pump have been observed (
⇨
Section 7.4.1 Page
39).
✓
The preservative used is compatible with the O-ring materials.
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/instructions (
⇨
Section 3.2 Page 12).
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. (

6.4 Returning to service after storage
For returning the pump to service observe the sections on commissioning/start-up (
⇨
Section 6.1 Page 28) and the operating limits. (
⇨
Section 6.2 Page 31)
In addition, carry out all servicing/maintenance operations before returning the
pump (set) to service. (
