sure relief valve (S), Graco part 24B910,
which is supplied with the pump, to prevent
fluid pressure from exceeding 50 psi (350 kPa,
Recommended air operating pressure is 40
psi (280 kPa, 2.8 bar) or less. As the air inlet
pressure approaches 50 psi (350 kPa,
3.5 bar), the relief valve will open and vent
fluid. Vented fluid must be routed to a con-
tainer in a non-hazardous location.

Maintenance
Flushing and Storage
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.
• 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.
Lubrication
• Flush with a fluid that is compatible with the
fluid being dispensed and the equipment
wetted parts.
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 in-line lubricator under normal operating
conditions.
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.
Tighten Threaded Connections
Always flush the pump and relieve the pres-
sure before storing it for any length of time.
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
