Figure 8. Seal Assembly
This seal is not designed for operation at
temperatures above 160
F (71 C). Do not
use at higher operating temperatures.
Inspect the seal plate (8), shaft sleeve (5) and the
impeller shaft for burrs or sharp corners, and re­
move any that exist.
If the wear ring (2) was removed, press the replace­
ment ring into the seal plate until fully seated. Apply
“Loctite Threadlocker No. 243” or equivalent com­
pound to the threads of the setscrews (3) and in­
stall them in the holes in the wear ring until snug.
The wear ring must seat squarely in the
seal plate bore; otherwise binding and/or
excessive wear will occur as the shaft
turns.
Apply a light coating of oil to the lip of the oil seal
(12) and press it into the pedestal bore with the lip
positioned as shown in Figure 6. Make sure the oil
seal is just flush with the outer face of the pedestal.
Use caution not to cut the lip of the oil seal on the
shaft keyway. Inspect and remove any sealant
shavings from the O.D. of the lip seal.
Lubricate the O‐ring (13) with light grease and in­
stall it in the groove in the pedestal.
Position the seal plate over the pedestal shoulder
and secure the seal plate to the pedestal with the
previously removed hardware (14 and 15).
Press the stationary seat and O‐ring into the seal
plate bore until fully seated. A push tube cut from a
length of plastic pipe would aid this installation.
The I.D. of the tube should be approximately the
same as the I.D. of the seal spring.
To prevent damaging the shaft sleeve O‐ring (6) on
the shaft threads, cover the threads with electrical
or duct tape. Slide the O‐ring over the shaft until it
seats against the shaft shoulder. Remove the tape
covering the threads. Check to ensure that the
shaft threads are free of any tape residue and clean
