Install the sleeve on the shaft.
3.
Perform these steps based on your dynamic seal configuration:
If your dynamic seal is
a...
Then...
Diaphragm seal
1.
Place an O-ring in the groove at the inner diameter of the follower (385)
and slide the assembly to the back of the sleeve.
2.
Place a gland plate over the follower (385) and slide the diaphragm (146)
over the sleeve to the face of the seat.
3.
Install four gland studs (353) in the stuffing box cover (184).
4.
Use the eye bolt, strap, and sling as required.
5.

Use the eye bolt, strap, and sling as required.
5.
Fit the repeller O-ring (412U) on the shaft sleeve and install the repeller
(262) tight against the sleeve.
6.
Make sure that the O-ring stays in the groove.
4.
Keep the repeller and sleeve assembly shouldered to the shaft, and adjust the rotating element until
the repeller-to-cover clearance is approximately 0.015 in. (0.4 mm).
5.
Fit the gasket (264) on the backplate (444).
6.
Install the backplate on the cover and tighten the nuts (357J) on the backplate studs (265A).
7.

If your dynamic seal is
a...
Then...
Diaphragm seal
1.
Slide the diaphragm (146) over the gland studs (353) and up against the
face of the stuffing box.
2.
Slide the gland plate (107) over the gland studs (353) and up against the
diaphragm (146).
3.
Thread the gland nuts (355) on and tighten evenly in a crossing pattern.
4.
Install the impeller and set the clearance per the instructions in the Com-
missioning, Start-up, Operations, and Shut-down chapter.
5.
Slide the follower (385) through the gland (107) until the step on the seal
