WARNING
Dangerous substances in the liquid pulsation
damper can cause a health hazard
Depending on the medium transferred, caustic burns
or poisoning are possible.
Wear protective clothing if necessary, e.g. pro-
tective gloves.
Rinse the liquid pulsation damper with a neutral
liquid and pump empty.
7.2.1. Flushing the liquid pulsation damper
When transferring aggressive media, KNF recommends flush-
ing the liquid pulsation damper 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 ser-
vice life of the diaphragm.
7.2.2. Cleaning the liquid pulsation damper
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.
Liquid pulsation damper free of hazardous materials
Hoses removed from the liquid pulsation damper
We recommend replacing the separating diaphragm when
the upper section is removed.
