WARNING
Health hazard due to dangerous substances in the
pump!
Depending on the substance transferred, caustic
burns or poisoning are possible.
Wear protective clothing if necessary, e.g. pro-
tective gloves.
Flush the pump with a neutral liquid and pump
empty.
8.2.1. Flushing the pump
When transferring aggressive media, in order to extend the
service life of valves and diaphragms, KNF recommends flush-
ing the pump with air (if necessary on safety grounds: with an
inert gas) or with a neutral liquid under atmospheric conditions
for a few minutes before switching off.
8.2.2. Cleaning the pump
Where possible, wipe the solenoid and the pump head with a
dry cloth. Do not use cleaning solvents as these may corrode
plastic parts.
