Figure E-3. Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Inspect the precision finished seal faces to ensure
that they are not damaged or contaminated with
foreign matter.
Position the seal plate (52) on a flat surface with the
impeller side down. Assemble the stationary seat
and gaskets in the seal clamp (15) with the white
gasket toward the seal cavity side of the stationary
seat. Secure the seal cap and stationary seal com­
ponents to the seal plate with the nuts (17).
NOTE
The white teflon seat gasket must be installed on
the seal cavity side of the stationary seat. The
'Chemlon' seal wedge should be lightly oiled be­
fore installation.
Slide the seal plate over the shaft until fully seated
against the pedestal (22). Be careful not to dam­
age the seal stationary seat on the shaft threads.
Align the pipe plug (18) with the pedestal opening
and temporarily secure the seal plate to the pedes­
tal using two capscrews and nuts (3/8-16 UNC X
1-1/2 inch long, not supplied).
Slide the rotating portion of the seal onto the lubric­
ated shaft sleeve with the seal face toward the
chamfered end of the sleeve. Position the seal re­
tainer the same distance from the impeller end of
the sleeve (or scribed line) as noted during disas­
sembly.
If a new sleeve is being used, or the correct loca­
tion location for the seal is not known, slide the
sleeve onto the shaft until it seats against the shaft
shoulder. Measure 1-1/4 inch (31,7 mm) out from
the stationary seat and mark the sleeve with a felt
tip marker. This is the designed working length of
the seal.
Secure the stationary portion of the seal to the
sleeve at the marked location by tightening the set­
