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 (30) and the external stationary seat
O‐ring with a very
small
amount of “P-80

Emul
sion” or water. See Figure 8 for seal part identifica

Figure 8. 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 (3) 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 (6 and 7). Install the bearing housing O‐
ring (28) and lubricate it with light grease.
To prevent damaging the shaft sleeve O‐ring (14)
on the shaft threads, stretch the O‐ring over a piece
of tubing 1‐1/2 I.D. x 1‐3/4 O.D. x 2‐inches long (38
mm x 43 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.
When installing a new cartridge seal assembly
,
remove the seal from the container, and remove
the mylar storage tabs, if so equipped, from be
tween the seal faces.
New cartridge seal assemblies may be
equipped with mylar storage tabs between
the seal faces. If so equipped, these stor
age tabs
must
be removed before install
ing the seal.
Lubricate the external stationary seat O‐ring with
light oil. Slide the seal assembly onto the shaft until
the external stationary seat O‐ring engages the
bore in the seal plate.
Clean and inspect the impeller as described in
Im

. Install the full
set of impeller shims (26) provided with the seal,
