out
out
of the housing (101).
2.
Assemble plate (9) onto diaphragm (10) with
screw (14). Rounded side of plate (9) should
face diaphragm. Make sure the side marked AIR
SIDE faces the center housing.
1
Apply a high-strength thread locker to
attach the screw to the diaphragm.
2
Apply a medium-strength thread locker
to the shaft side of the screw (14).
3.
Screw assembled diaphragm assembly into shaft
(24) and hand tighten.

NOTE:
NOTE: Apply waterproof, sanitary lubricant to the
clamp (21) and clamping surface of the cover (4,
15) to ease assembly.
7.
Align the fluid covers (15) and the center
housing. Secure the covers with the clamps
(21) and hand tighten. The opposing diaphragm
may protrude away from the center housing
after the first fluid cover is secured, leaving
a gap between the center housing and the
second fluid cover. Do not try to force the
diaphragm into position. Instead, use the
diaphragm install tool to position the diaphragm
and allow fluid cover installation. Refer to
Using Diaphragm Install Tool, page 10
for use
of the diaphragm install tool to position the
diaphragm and allow fluid cover installation.
