Maintenance Schedule
Establish a preventive maintenance schedule,
based on the pump’s service history. Scheduled
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. An inline lubricator is not needed, and is not
recommended, under normal operating conditions.
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 compatible solvent.
Always flush the pump and relieve the pressure
before storing it for any length of time.
