Shutdown
6
Warning!
Rotating parts or pressurised spout liquids
Possible dangerous situation: Severe or fatal injuries!
Do not work on rotating pump!
6.1
Switch-of
1.
Shutdown the pump by turning off its electrical energy supply.
2.
Shutdown valves.
Caution!
Risk of burns due hot pump parts.
Possible dangerous situation: Minor injuries!
Use protective gloves!
6.2
Draining
Drain and clean the pump after shutdown, in particular if:
The pump is sited in the open air and it is possible for the pumping medium to freeze due to
weather conditions,
The pumping medium is prone to deposit formation, or cooling, or if the pumping medium
hardens due to a chemical reaction taking place.
6.3
Decommissioning
If the pump is to be taken out of service for an extended period, take the following action:
Clean well the pump and flush it with soap water.
For shutdown periods in excess of 6 months, remove the stator in order to avoid pressure
marks in the elastomeric material, which would cause a higher starting torque when the
pump is subsequently re-started.
For pumps with rotors not made out of stainless steel (e.g. from 1.2436), remove the stator
and cover the rotor in grease (Design see data sheet).
Open drain plugs and cleaning covers to draining the pump!
