Fig. 58: Replacing the pump diaphragm
1. Grasp both sides of the pump diaphragm (
12
), lift it up and
screw it out anti-clockwise.
2. Remove the support (
11
) and shim ring (
10
) from the threaded
bolt of the diaphragm, and put aside in a safe place.
3. Inspect all parts for soiling, and clean if necessary.
4. Push the support (
11
) and shim ring (
10
), in that order, onto
the threaded bolt of the new pump diaphragm (
12
).
5. Move up the connecting rod (
9
) as far as it will go.
6. Screw the pump diaphragm (
12
) with support (
11
) and shim
ring (
10
) clockwise onto the connecting rod (
9
), and hand-
tighten.
Ensure that the pump diaphragm is properly screwed into
position. If the pump diaphragm is not screwed in right up to
the stop point, the pump may be mechanically obstructed and
become damaged as a result.
