Maintenance
Maintenance Schedule
Establish a preventive maintenance schedule,
based on the pump’s service history. Sched-
uled maintenance is especially important to
prevent spills or leakage due to diaphragm
failure.
Lubrication
The pump is lubricated at the factory. It is
designed to require no further lubrication for
the life of the pump.
Tighten Threaded Connections
Before each use, check all hoses for wear or
damage and replace as necessary. Check to
be sure all threaded connections are tight and
leak-free. Check fasteners. Tighten or retorque
as necessary. Although pump use varies, a
general guideline is to retorque fasteners every
two months. See Torque Instructions,
page 16.
Flushing and Storage
• Flush before fluid can dry in the equipment,
at the end of the day, before storing, and
before repairing equipment.
• Flush at the lowest pressure possible.
Check connectors for leaks and tighten as
necessary.
• Flush with a fluid that is compatible with the
fluid being dispensed and the equipment
wetted parts.
Flush the pump often enough to prevent the
fluid you are pumping from drying or freezing
in the pump and damaging it. Use a compati-
ble solvent.
Always flush the pump and relieve the pres-
sure before storing it for any length of time.
