Figure 5. 46513-150 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 (23) was removed, install the seal
plate gasket (3). Position the seal plate over the
shaft and secure it to the bearing housing with the
hardware (21 and 22).
To prevent damaging the shaft sleeve O‐ring (20)
on the shaft threads, stretch the O‐ring over a piece
of tubing 1‐1/4 I.D. x 1‐1/2 O.D. x 2‐inches long (32
mm x 38 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, re­
move 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 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 (24) provided with the seal,
and screw the impeller onto the shaft until it is
seated against the seal (see Figure 6).
