Figure 11. 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 (27) 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 just large enough to slide over the shaft.
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
peller Installation and Adjustment. Install the full
set of impeller shims (26) provided with the seal,
and screw the impeller onto the shaft until it is
seated against the seal (see Figure 12).
