Before starting, bump the motor to check if the motor fan is rotating
clockwise when seen from the motor back. If the motor fan cannot be
seen, look through the seal guard to view the stub shaft. (Bump
means to momentarily apply power to the motor and then immediately
remove power.)
Check the following:
•
Flow direction is correct.
•
Suction inlet and discharge outlet lines are hooked up correctly.
•
All connections are tightened.
When practical, an eccentric tapered reducer should be used to prevent
air pockets from forming in the lines or in the pump.
Pay attention to circumstances that could lead to pump cavitation:
•
Low pressure in the suction line due to line restrictions.
•
Air in the suction inlet line.
•
Temperature of the fluid being pumped is too
high.
•
Pump is oversized for the fluid being pumped.
Ensure that there is a sufficient supply of fluid to
be pumped.
Check the motor for vibration, unusual noises, or
any other abnormalties.
INSTALLATION
OPERATIONAL CHECK
Never run the pump with both the suction side and the
pressure side blocked. This will cause serious
damage to the pump.
Eccentric Tapered
Reducer
Do not operate the pump without the
seal guard in place.
Always check rotation without liquid in
the pump.
