The diaphragm and valves are the only wearing parts in the
pumps. They are easy to replace.
The valves and diaphragm should generally be replaced at
the same time. If the diaphragm is not replaced at the same
time as the valves, the specified output of the pump can no
longer be ensured after the maintenance is performed.
With multi-headed pumps, parts may be interchanged be-
tween the individual pump heads.
à
Replace the diaphragm, valve springs and seals of the in-
dividual pump heads in sequence.

essary, e.g., protective gloves,
