INSTALLATION OF NEW SEAL
The precision lapped faces of mechanical seal are easily damaged. To
prevent leaks, handle replacement seal carefully. Do not touch seal
mating faces.
1. Clean seal cavity area of casing cover (Ref. 3). Lubricate rubber portion
of seal seat (Ref. No. 4 without spring) with soapy water. Protect seal face
with cardboard and press squarely into place, with polished side up. Then
lay casing cover onto adapter (Ref. No. 2), and center it around motor
shaft.
IMPORTANT:
To avoid rubbing during operation, maintain gap between seal
and motor shaft until assembly is complete.
2. Clean outside of shaft stem on impeller (Ref. No. 6). Lubricate inside rubber
portion of seal head (Ref. No. 4 with spring) with soapy water. Gently slide
seal onto impeller with polished side facing away from impeller.
3. Carefully screw impeller back onto motor shaft by turning clockwise. Be
sure to snug-up impeller by holding motor shaft as during disassembly.
Add impeller seal (Ref. No. 7), then impeller nut (Ref. No. 8) and tighten.
4. Carefully lay casing seal (Ref. No. 5) into desired position.
NOTE:
Casing may be rotated to position discharge port at various angles.
5.
Use fasteners and washers (Ref. Nos. 10 & 11) to attach casing.
IMPORTANT:
To avoid leaks, be sure to tighten fasteners in stages to prevent
casing seal from slipping and becoming pinched.
6.
When assembly is complete, check for interference by spinning motor
shaft by hand and listening. If rubbing heard, loosen fasteners and adjust
casing cover until rubbing is gone (casing may also require adjustment on
high head models). If rubbing still persists, remove casing. Then check to
be sure impeller is completely tightened and not binding on shaft threads.
Seal will produce minor drag when spinning motor shaft, but rubbing
anywhere else must be eliminated! Otherwise, damage to pump and/or
motor may occur.
