Diaphragm and valve plates/seals are the only wear parts in
the pumps. They are easy to replace.
Valve plates/seals and diaphragm should generally be re-
placed at the same time. If the diaphragm is not replaced at
the same time as the valve plates/seals, the specified output
of the pump can no longer be ensured after the maintenance
is performed.
