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

Preventative maintenance should be performed to reduce the chance of premature
failure.
