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

Lubrication
The pump is lubricated at the factory. It is designed
to require no further lubrication for the life of the
pump. There is no need to add an inline lubricator
under normal operating conditions.
The air valve is designed to operate unlubricated. If
lubrication is desired, every 500 hours of operation
(or monthly), remove the line from the pump air inlet
and add two drops of machine oil to the air inlet.
The pump is lubricated at the factory. It is designed
to require no further lubrication for the life of the
bearings.

NOTICE
Do not over-lubricate the pump. Lubricant
is exhausted through the muffler and could
contaminate your fluid supply or other equipment.
Excessive lubrication can also cause the pump to
malfunction.

Storage
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
• Flush before fluid can dry or freeze 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 sanitizing solution that is compatible
with the fluid being dispensed and the equipment
wetted parts.
• Flushing schedule will vary based on particular
uses.
• Always cycle the pump during the entire flushing
process.
Always perform the
Pressure Relief Procedure, page 21
and flush the
pump before storing it for any length of time.
1.
Insert the suction tube into sanitizing solution.
2.
Open air regulator (H) to supply low pressure
air to the pump. Use the and center section
regulator (R) to adjust the center section air
pressure relative to the fluid outlet pressure.
