OPERATION
NOTE:
All fluids used in this pump must be chemically
compatible with the materials used to manufacture the
“wetted parts”. Consult your chemical supplier to ensure
compatibility.
TO START PUMP
:
1. Connect air coupler to pump and turn the air regulator to
the minimum setting.
2. Direct outlet hose into an approved waste oil container.
3. Slowly adjust air regulator until pump is primed and is
running smoothly. Be sure all air has been purged from
system. The pump should only take a few strokes to
prime. However, in a large system, it may take longer.
4. Use the air regulator to control the pump speed and cycle
rate. Always use the lowest pressure needed to obtain
the desired flow rate. This will increase pump and seal
life!
5. Never allow a pump to run dry of the fluid being pumped.
A dry pump quickly speeds up and can damage the air
motor. If it speeds up, shut off air supply immediately. Refill
the supply container and prime the pump to eliminate air
in the fluid line.
NOTE:
To prevent air from being sucked into the pump and
fluid lines, if the supply container should run dry, use a low-
level cutoff valve (4411-010) at the pump fluid intake.
6. Read and follow the instructions supplied with each
component in your system.
7. If the pump will be unattended for any period of time, or
to shut off the system at the end of the work shift,
always
follow the
Pressure Relief Procedure.
PRESSURE RELIEF
PROCEDURE:
Follow this procedure
whenever you shut off the pump, when checking or servic-
ing any part of the system and when installing, cleaning
or changing any part of the system.
1 ) Disconnect the air to the pump.
2) Point dispensing valve away from
yourself and others.
3) Open dispensing valve until
pressure is relieved.
WARNING
!
WARNING
!
Pump develops 195 PSI (13.3
BAR) maximum working pressure
at 150 PSI (10.3 BAR) maximum inlet air pressure. NEVER
exceed the maximum working pressure of the lowest rated
equipment of your system.
