Step 7.
Figure 7
NOTE:
Due to varying torque values, one
of the following two situations may occur:
1) The outer piston, diaphragm and inner
piston remain attached to the shaft and
the entire assembly can be removed from
the center section
.
Step 8.
Figure 8
2) The outer piston, diaphragm, inner
piston, and disc spring separate from the
shaft which remains connected to the
opposite side diaphragm assembly
(Figure
8).
PTFE-fitted pumps come standard with
back-up diaphragms (not shown).
Step 9.
Figure 9
To remove the diaphragm assembly from
the shaft, secure shaft with soft jaws (a
vise fitted with plywood or other suitable
material) to ensure shaft is not nicked,
scratched, or gouged. Using an adjust-
able wrench, remove diaphragm assem-
bly from shaft. Inspect all parts for wear
and replace with genuine Wilden parts if
necessary.
Step 4.
Figure 4
Remove the discharge valve balls, seats
and o-rings from the discharge manifold
and inspect for nicks, gouges, chemical
attack or abrasive wear. Replace worn
parts with genuine Wilden parts for reli-
able performance. PTFE o-rings should
be replaced when reassembled.
Step 5.
Figure 5
Inspect the valve seat, valve seat o-
ring, and valve ball from intake manifold.
Check for nicks, gouges, chemical attack
or abrasive wear. Replace worn parts with
genuine Wilden parts for reliable perfor-
mance. PTFE o-rings should be replaced
when reassembled.
Step 6.
Figure 6
With the 3/4” box wrench or by rotat-
ing the diaphragm by hand, remove the
diaphragm assembly.
