Pump Shutdown
At the end of the work shift and before you check,
adjust, clean or repair the system, follow the Pressure
Relief Procedure, page 12.
Maintenance
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 nor-
mal 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 neces-
sary. Although pump use varies, a general guideline is
to retorque fasteners every two months. See Torque
Instructions, page 14.
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 con-
nectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
• 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. Use a compatible solvent.
