Figure E−3. Seal Assembly
The standard seal is not designed for oper-
ation at temperatures above 160
_F (71_C).
Do not use at higher operating tempera-
tures.
Lubricate the stationary seat O-rings with water or
light oil, and install them in the stationary seat. In-
stall the stationary seal element in the stationary
seat. Position the seal plate on a flat surface with
the impeller side up and press this stationary sub-
assembly into the front of the seal plate until it seats
squarely against the bore shoulder.
Position the assembled seal plate and stationary
seat over the shaft, and temporarily secure it to the
pedestal with three 1/2-inch x 2-inch long caps-
crews and nuts (not supplied). Be careful not to
damage the stationary element or roll or cut the lip
of the oil seal (36) on the shaft keyway.
Lubricate the seal sleeve O-ring with a small
amount of light oil and install it in the groove in the
I.D. of the sleeve.
Lubricate the seal sleeve with a small amount of
light oil and slide the rotating subassembly (con-
sisting of rotating element, bellows and retainer),
onto the sleeve until the rotating element is just
flush with the turned end of the sleeve.
Slide the sleeve and subassembled seal onto the
shaft until the seal faces contact and the sleeve
seats against the shaft shoulder.
Install the seal spring. Lubricate the seal as indi-
cated in LUBRICATION after the impeller, remain-
ing pump components, bottle oiler and piping are
installed.
