Figure E-4. 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 O‐rings (9 and 17) with a small
amount of grease and install them on the seal plate
(8).
Position the seal plate on a flat surface with the im­
peller side up. Press the stationary subassembly
(consisting of the stationary seat, O‐rings and sta­
tionary element) into the seal plate until the station­
ary seat bottoms against the seal plate bore.
Slide the seal plate over the shaft and secure it to
the pedestal with the hardware (29 and 65).
To prevent damaging the shaft sleeve O‐ring (71)
on the shaft keyway, cover the keyway with electri­
cal tape. Slide the O‐ring over the shaft until it seats
against the shaft shoulder. Remove the tape cover­
ing the keyway. Check to ensure that the shaft is
free of any tape residue and clean as required be­
fore proceeding with seal installation.
Lubricate the O.D. of the shaft sleeve and slide the
rotating subassembly (consisting of the rotating
element, retainer and bellows) onto the sleeve until
the rotating element is just flush with the cham­
fered end of the shaft. Slide the sleeve and rotating
subassembly onto the shaft until the seal faces
contact. Continue to push the sleeve through the
seal until it bottoms against the shaft shoulder. In­
stall the seal spring.
Lubricate the seal assembly as indicated in
LUBRICATION, after the impeller has been in­
stalled.
Impeller Installation And Adjustment
(Figure E‐3)
Inspect the impeller, and replace it if cracked or
badly worn. Install the same thickness of impeller
adjusting shims as previously removed, and install
the impeller key (12). Apply a thin, uniform coat of
“Never‐Seez” or equivalent compound to the shaft
area under the impeller and press the impeller onto
