Maintenance
Preventive Maintenance
Schedule
The operating conditions of your particular pump determines how often maintenance is required. Establish a
preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your pump.
Tighten Threaded Connections
Check that all threaded connections are tight at routine
intervals.
Tighten Packings
Operation
The packings included in your pump have the ability to
be adjusted to stop leaks that develop when the seals
are worn. If a leak develops in the pump’s fluid section,
tighten the packing nut clockwise by 1/16th of a turn, or
lower, until the leak is eliminated. The life of the packing
can be affected by over-tightening the packings. If the
packing nut needs to be tightened repeatedly after short
intervals, replace the packing.
Storage
If the pump is going to be stored for long periods, it is
recommended that the pump be flushed with a
light-weight oil or rust prohibiter to protect pump components. Store the pump with protective fluid inside whenever possible.
