9.2. Cleaning
Flushing the pump
When 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.
Cleaning the pump
Wipe the outside of the pump with a soft dry cloth. Ensure that
any cleaning solvents used will not damage the materials of
the pump head and crankcase housing (check material
resistance properties).
Cleaning the pump head
The pump head should be cleaned only if the pump is no
longer working properly (no suction, inadequate flow rate or
reverse suction of the pumped medium), or if the pump head
cannot be cleaned satisfactorily by flushing.
Remove pump head, clean and reinstall (see section 8.3).
