Operating Instructions and Parts Manual

MAINTENANCE
Always disconnect power source before
attempting to install, service, or maintain the pump.
Toujours débrancher le cordon d'alimentation
avant d'essayer d'installer, de réparer ou de faire l'entretien de la
pompe.
IMPELLER REPLACEMENT
NOTE: These parts are designed to handle most clear, nonflammable
liquids with slight amounts of abrasives. When impeller vanes become
worn from use, or damaged due to pumping abrasive liquids or trash,
pump performance will be reduced or prevented altogether and will void
warranty.
1. Remove the four cover plate screws holding motor housing and
pump housing together. Cover plate is now free and can be
removed.
2. Inspect gasket and impeller for wear and damage. If there is any
evidence of wear or damage, replace the part(s).
3. Lubricate new impeller with vegetable oil and reinstall by aligning flat
on impeller hub with flat on motor shaft.
4. Reassemble gasket, cover plate, and cover plate screws.
SHAFT SEAL REPLACEMENT
Motor shafts are sealed with factory pre-lubricated lip-type seals which
are good for the life of the pump. If the seal leaks, it is usually because
the pump has handled abrasive liquids. If the motor shaft is scored (deep
grooves), the complete pump must be replaced.
1. Remove and inspect impeller parts as specified in the impeller
replacement instructions. Replace worn parts.
2. Remove two pump body mounting screws and slide pump body
from motor. Pry out seal retaining ring and push worn shaft seal
from inside of pump body.
3. Lubricate new seal with lightweight vegetable oil, push it into pump
body with lip facing away from motor, and push in seal retaining ring.
4. Reassemble pump body onto motor with mounting screws. Follow
steps 3 and 4 in Impeller Replacement.
