VORSICHT
Diaphragm and valve plates are the only parts of the pump subject
to wear. They are simple to change.
Always change diaphragm, valve plates and sealing rings at the
same time. If diaphragm and valve plates are not changed at the
same time the nominal performance of the pump is not guaranteed
after the service.
Health hazard due to dangerous substances in the
pump
Depending on the substances transferred, caustic
burns or poisoning are possible.
WARNUNG
Wear protective clothing if necessary, e.g.
protective gloves.
Clean pump with suitable measures.
After opening the pump head, or replacing the diaphragm and
valve plates the high gas-tightness is no longer guaranteed. A leak
test is able to verify that the original standard of gas-tightness has
been achieved.
