Installing New Seal

Cardboard Washer
(supplied with
seal)
Place bracket on a smooth, flat surface, pump side up.
Apply a small amount of mineral oil to O-Ring on stationary
seal and press into seal cavity. Cover ceramic face with
cardboard washer and press straight in using a piece of
pipe or tubing.
3
Apply small amount of mineral oil to inside diameter of
rubber ring in rotating seat and outside of shaft sleeve.
Slide rotating seat onto shaft, polished face first, until it is
tight against ceramic face. Compress seal spring and install
retaining ring in shaft sleeve groove (if used). Place impeller
key in motor shaft keyway. Slide impeller on to shaft as far
as possible.

Install gasket and volute on bracket. Use a new gasket
or O-Ring when reassembling to prevent leakage ( a coat
of grease on gasket will aid in future disassembly and
maintenance).
Apply anti-seizing compound to cap-screws and tighten
securely.
Procedure and parts will vary slightly depending on pump style.
