8.2. Cleaning
WARNING
Health hazard due to dangerous substances in the
pump
Depending on the medium pumped, risk of caustic
burns or poisoning.
Wear protective clothing if necessary, e.g.
protective gloves.
Rinse the pump with a neutral liquid and pump
empty.
8.2.1. Flushing the pump
If pumping aggressive media, KNF recommends flushing the
pump with a neutral fluid under atmospheric conditions for a
few minutes before switching off, to extend the service life of
valves and diaphragm.
8.2.2. Cleaning the pump
Where possible, wipe the components with a dry cloth. Do not
use cleaning solvents as these may corrode plastic parts.
If there is compressed air available, blow off components.
Pump or drive must be switched off and disconnected from
mains.
The pump must be free of any hazardous substances.
Hoses must be disconnected from the pump head.
We recommend replacing the diaphragm when the head
parts are removed.
