To ease installation of the seal, lubricate the shaft

and O‐rings with a very small amount of light lubri

Figure 5. 46512-192 Seal Assembly

This seal is not designed for operation at
temperatures above 160

F (71

C). Do not

use at higher operating temperatures.

Lubricate the stationary seat O‐ring with water or
light oil, and press the stationary subassembly into
the front of the seal plate (4) until it seats squarely
against the bore shoulder.

Install the seal plate gasket (5). Position the seal
plate and stationary seat over the shaft and secure
it to the bearing housing (9) with the hardware (7
and 8). Be careful not to damage the stationary
element on the shaft threads.

NOTE

It is recommended that a tapered sleeve be in
stalled over the threads of the impeller shaft to ease
installation of the rotating seal components.

Lubricate the shaft with a small amount of light oil
and slide the rotating subassembly (consisting of
the rotating element, bellows and retainer) onto the
shaft. Apply firm, steady pressure on the seal re
tainer until it slides onto the shaft and the seal faces
contact.

Install the seal spring. Lubricate the seal as indi
cated in LUBRICATION after the impeller is in
stalled.
