9.4.2 Removing the valves and seals
Remove the connecting plate (
5
) from the intermediate plate (
7
).
Take the valve plate (
6
) out of the intermediate plate (
7
).
Remove the resonating diaphragm (
3
) from the connecting plate
(
5
).
Remove the O-ring (
4
) from the head plate.
Carefully grip the diaphragm (
8
) and remove by turning anti-clock-
wise. Remove the washers (
9
) and make sure that no washers
9
fall into the pump housing.
We recommend replacing the diaphragm (
8
).
9.4.3 Cleaning the parts
Clean the diaphragm (
8
), O-ring (
4
), resonating diaphragm (
3
),
valve plate (
6
), intermediate plate (
7
) and connecting plate (
5
) with
a cloth and then blow off with compressed air.
9.4.4 Installing the diaphragm
Place the same number of washers on the connecting rod (
9
) as
were there previously. Make sure that no washers (
9
) fall into the
pump housing.
Screw in the diaphragm (
8
).
By lightly pressing on the diaphragm push the ridge on the under-
side of the diaphragm into the groove of the housing.
9.4.5 Installing the valve plate
Place the dust-free valve plate(
6
) into the intermediate plate (
7
),
making sure it is in the correct position.
9.4.6 Installing the pump head
Insert the resonating diaphragm (
3
) in the connecting plate (
5
) and
cover with the head plate (
2
) fitted with a new O-ring (
4
).
The positions of the intermediate plate (
7
), the connecting plate
(
5
) and the head plate (
2
) with respect to one another are deter-
mined by the arrangement of the visible grooves.
Insert the four head screws (
1
) into the through holes of the pump
head.
Make sure that the flow direction of the pump head (see direc-
tional arrow on the head plate (
2
)) is the same as previously.
Place the pump head onto the pump housing and alternately
tighten the four head screws (
1
). The maximum tightening torque
is 1.5 Nm.
Check that pump and system are leak-tight after maintenance.
