Information on procedure
WARNING
8.2.1. Flushing the pump
➔ If pumping aggressive media, KNF recommends flushing the
pump with air under atmospheric conditions for several
minutes prior to switch off (if necessary for safety reasons: use
an inert gas). This will extend the service life of the diaphragm.
8.2.2. Cleaning the pump
➔ Where possible, wipe the components with a soft dry cloth. Do
no use cleaning solvents as these may corrode plastic parts.
➔ If there is compressed air available, blow off the separate
parts.
▪
Pump must be switched off and mains plug removed from
the socket.
▪
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.
