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
packings. There is no need to add an inline lubricator
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
mounting bolts. 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.
• Use solvent that is compatible with the equipment
wetted parts and the material being dispensed.
• Always flush the pump and relieve the pressure
before storing it for any length of time.
NOTICE
Flush the pump often enough to prevent the fluid
you are pumping from drying or freezing in the
pump and damaging it.
