IMPELLER REPLACEMENT
These parts are designed to handle most clear, non ammable liquids with slight amounts
of abrasives. When impeller vanes become worn from use, or damaged due to pumping
abrasives liquids or trash, pump performance will be reduced or prevented altogether.
Remove the four cover plate screws holding motor housing and pump housing 6.
together. Cover plate is now free and can be removed.
Inspect gasket and impeller for wear and damage. If there is any evidence or wear or 7.
damges, replace the part(s).
Lubricate new impeller with white grease or lightweight oil and reinstall by aligning 8.
at on impeller hub with at on motor shaft.
Reassemble gasket, cover plate, and cover plate screws.9.
SHAFT SEAL REPLACEMENT
Motor shafts are sealed with factory pre-lubricated lip-type seals which aregood 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.
Remove and inspect impeller parts as speci ed in the impeller replacement 1.
instructions. Replace worn parts.
Remove two pump body mounting screws and slide pump body from motor. Pry out 2.
seal retaining ring and push worn shaft seal from inside of pump body.
Lubricate new seal with lightweight oil, push it into pump body with lip facing away 3.
from motor, and push in seal retaining ring.
Reassemble pump body onto motor with mounting screws. Follow steps 3 and 4 in 4.

or when standing on wet r damp surface or in
water. Fatal electrical shock could occur.
A ground fault circuit interrupter (GFCI) is required. 1.
Risk of electrical shock! This pump is supplied
with a grounding conductor and grounding
type attachment plug. A grounded receptacle in
conformance with current NEC and local codes
must be used (See Figure 1). Do NOT use in
swimming pool areas.
Model BT12 operates on 115V only.2.
Use an extension cord only if necessary. Follow the 3.
Extension Cord Length Table at the bottom of the page
for proper gage of 3-wire, grounding type extension
cord.
Risk of fatal electrical shock! Never cut o the
round grounding prong. Cutting the cord or
plug will void the warranty and make the pump
inoperable.
Use a strainer when pumping from a creek, pond, or 4.
source where foreign objects may be sucked into the
pump. The strainer should prevent solids from entering
the inlet line.
A regular garden hose may be used as a discharge line.5.
Pump operation will be seriously hindered or prevented 6.
if the inlet hose is over 15 feet long or if the vertical
pumping distance exceeds 10 feet.
At times, an overload due to over heating, low voltage, 7.
jammed impeller, etc. may shut the pump o . Unplug
or turn o the pump and wait at lease ten minutes. The
pump will cool and automatically reset.
Motor should never be operated for more than 2 hours 8.
continuously. Critical heating can occur and might
severely damage the pump and void warranty.
OPERATION:
Add 1 tablespoon of vegetable oil to both inlet and 1.
outlet to prime.
Attach included 6’ suction hose to inlet of pump. Attach 2.
garden hose to outlet of pump. There must be a gasket
in place to insure that these connections are airtight,
otherwise the pump will not prime. Connect water
suction attachment to the open end of inlet hose and
place below water surface. (Water suction attachment is
optional). The water suction attachment is designed to t
the male end of a garden hose. Place the water suction
attachment as near as possible to the middle of the
water that is to be pumped.
