Figure 6. Seal Assembly
This seal is not designed for operation at
temperatures above 160
F (71
C). Do not
use at higher operating temperatures.
Lubricate the stationary seat O‐rings with water or
light oil, and install them in the stationary seat. In
stall the stationary seal element in the stationary
seat. Press this stationary subassembly into the
front of the seal plate (5) until it seats squarely
against the bore shoulder.
Install the seal plate gasket (6). Position the seal
plate and stationary seat over the shaft and secure
it to the bearing housing (9) with the hardware (15
and 16).
Be careful
not to damage the stationary
element on the shaft threads.
NOTE
It is recommended that a tapered sleeve be in
stalled over the threads of the impeller shaft to ease
installation of the rotating seal components.
Lubricate the shaft with water or a
small
amount of
light oil and slide the rotating subassembly (con
sisting of the rotating element, bellows and retain
er) onto the shaft. Apply firm, steady pressure on
the seal retainer as it slides onto the shaft until the
seal faces contact.
Install the seal spring. Lubricate the seal as indi
cated in
LUBRICATION
after the impeller is in
stalled.
Impeller Installation and Adjustment
(Figure 2)
Inspect the impeller and replace it if cracked or
badly worn. Inspect the impeller and shaft threads
for dirt or damage, and clean or dress the threads
as required.
The shaft and impeller threads
must
be
completely clean before reinstalling the im
