SERVICING YOUR SUBMERSIBLE PUMP
Pump should be disconnected from the electric power supply before proceeding to do
any service or maintenance.
The design of the “F” series high temperature pump models is unique and
requires specific knowledge to perform the proper assembly. BJM Pumps
recommends that all electrical service work be performed at the factory, or by a
factory trained and certified repair technician, to insure that the materials and
assembly methods meet BJM standards.
MAINTAINING YOUR PUMP

Pump should be disconnected from the electric power supply before proceeding
to do any service or maintenance.

Pump should be inspected at regular intervals (At least 2 times per year).

More frequent inspections are required if the pump is used in a harsh
environment.

Preventative maintenance should be performed to reduce the chance of
premature failure.

Worn impellers and lip seals should be replaced.

Cut or cracked power cables must be replaced. (Never operate a pump with a
cut, cracked or damaged power cable.)

Seal oil should be checked once per year.

Maintenance should always be done when taking a pump out of service before
storage.
1) Clean pump of dirt and other build up.
2) Check condition of oil around the shaft seals.
3) Check hydraulic parts: check for wear.
4) Inspect power cable. Make sure that it is free of nicks or cuts.
CHANGING SEAL OIL
Changing the seal oil in the S-F & SX-F Series pumps is very easy.
1) Make sure that the pump is de-energized and locked out for service.
2) Lay the pump down on its side.
