Operation (Continued)
Maintenance
Always disconnect
power source before
attempting to install, service, or maintain the
pump.
IMPELLER REPLACEMENT
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.
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 white
grease or lightweight 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 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.
MOTOR BRUSH REPLACEMENT
PC1 Model is
equipped with lifetime
brushes. Brush replacement is not necessary.
Brushes for the PC2
pump should be
inspected after 75 hours of operation
and replace if worn. They must be
replaced every 100 hours of operation.
Service one brush at a time.
1) Disconnect pump from power supply.
2) Remove brush caps with screwdriver.
3) Remove old brush assembly.
4) Insert new brush assembly.
5) Replace brush caps.
