it is in contact with the housing and centered

with respect to the bore.

Assembling the pump heads

Place the head cover over the diaphragm. Check for its correct orien-

tation by aligning it beforehand with the housing cover which has to be

put over it later on.

+

Pay attention that the diaphragm stays positioned centrally so that it

will become clamped uniformly between housing and head cover.

Place the valves at their respective positions

on the head cover.

Make sure that the valves are correctly seat-

ed. See figure for the correct position of the

valves: Valves at the outlet with round cen-

tered opening (A) under valve; valves at the

inlet with kidney-shaped opening (B) beside

valve.

Place the housing cover with housing cover insert onto the head cover.

By turning the eccentric bushing, bring the connecting rod into the up-

per turning point position (max. stroke of the rod).
