pump. Wear patterns on the finished faces
cannot be realigned during reassembly.
Reusing an old seal could result in prema
ture failure.
To ease installation of the seal, lubricate the shaft
sleeve O‐ring and the external stationary seat O‐
ring with a very
small
amount of light lubricating oil.
See Figure 5 for seal part identification.

Figure 5. Cartridge Seal Assembly
This seal is not designed for operation at
temperatures above 160
F (71
C). Do not
use at higher operating temperatures.
If the seal plate (4) was removed, install the seal
plate gasket (5). Position the seal plate over the
shaft and secure it to the bearing housing with the
hardware (7 and 8).
To prevent damaging the shaft sleeve O‐ring (not
shown) 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. Re
move the tape covering the threads. Check to en
sure that the shaft threads are free of any tape resi
due and clean as required before proceeding with
seal installation.
When installing a new cartridge seal assembly
,
remove the seal from the container and lubricate
the external stationary seat O‐ring with light oil.
Slide the seal assembly onto the shaft until the ex
ternal stationary seat O‐ring engages the bore in
the seal plate.
Clean and inspect the impeller as described in
Im
peller Installation and Adjustment
. Install the full
set of impeller shims (3) provided with the seal, and
screw the impeller onto the shaft until it is seated
against the seal (see Figure 6).
