Figure 2. Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Lay the seal plate (7) on a flat surface with the im­
peller side facing up.
If removed at disassembly, press the replacement
wear ring (7) into the seal plate until it seats square­
ly against the shoulder bore.
The wear ring must seat squarely in the
seal plate bore or binding and/or exces­

Subassemble the O‐ring onto the stationary ele­

sembly into the seal plate until it seats squarely
against the shoulder bore.
Carefully slide the assembled seal plate and sta­

to nick or damage the stationary seat. Use two
capscrews and nuts (not supplied) to temporarily
secure the seal plate to the pedestal.
Subassemble the rotating element into the retainer
and bellows. Lubricate the I.D. of the bellows with
water, and slide this subassembly over the shaft
sleeve until the seal face is just flush with the under­
cut end of the sleeve.
To prevent damaging the shaft sleeve O‐ring (11)
on the shaft threads, stretch the O‐ring over a piece
of tubing 7/8 inch I.D. x 1 inch O.D. x 2‐inches long
(22 mm x 25 mm x 51 mm). Slide the tube over the
shaft threads, then slide the O‐ring off the tube and
onto the shaft. Remove the tube, and continue to
slide the O‐ring down the shaft until it seats against
the shaft shoulder.
Slide the assembled shaft sleeve and rotating por­
