C). Do not
use at higher operating temperatures.
If the seal plate (4) was removed, install the seal
plate O‐ring (26) and lubricate it with light grease.
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). Install the
bearing housing O‐ring (28) and lubricate it with
light grease.
To prevent damaging the shaft sleeve O‐ring (32)
on the shaft threads, cover the threads with electri­
cal 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 as required before proceeding with seal
installation.
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
peller Installation and Adjustment. Install the full
set of impeller shims (2) provided with the seal, and
screw the impeller onto the shaft until it is seated
against the seal (see Figure 9).
