WARNING
EXCESSIVE INLET PRESSURE. Can cause

explosion resulting in severe injury or death. Do not
exceed maximum operating pressure of 10,000 p.s.i.g
(690 bar) at 100 p.s.i.g (6.9 bar) inlet air pressure. Do
not run pump without using a regulator to limit air
supply pressure to the pump.
WARNING
EXCESSIVE MATERIAL PRESSURE. Can cause
IMPORTANT
equipment failure resulting in severe injury or prop-
erty damage. Do not exceed the maximum material
pressure of any component in the system.
This is one of four documents which support the pump.

GENERAL INFORMATION LUBRICATION PISTON PUMPS
Pump ratio is an expression of the relationship between the pump
motor area and the lower pump end area. EXAMPLE: When 100 p.s.i.g
(6.9 bar) inlet pressure is supplied to the motor of a 100:1 ratio pump it
will develop a maximum of 10,000 p.s.i.g (690 bar) fluid pressure (at no
flow) - as the fluid control is opened, the flow rate will increase as the
motor cycle rate increases to keep up with the demand.
NOTICE
Thermal expansion can occur when the fluid in the ma-
terial lines is exposed to elevated temperatures. Example: Material lines
located in a non-insulated roof area can warm due to sunlight. Install a
pressure relief valve in the pumping system.

TROUBLE SHOOTING
No material at outlet. (Pump continuously cycles).
Air bypasses through exhaust port.
Empty material supply. Disconnect the air, replenish the
material supply.
y
Foreign matter is holding air valve open or lacks lubrica-
tion. Consult factory for nearest Service Center.
y
Foreign matter is holding foot valve seats open in lower
pump tube assembly. Remove lower pump tube assem-
bly and clean valve seats.
y
Motor stalls.
Foreign matter in pump, hose, control valve or spray tip
obstructing material flow. Check material supply hose
and control valve or tip.
y
Pump operates sluggishly, tends to stick when air is
applied or control is opened.
Air not getting to pump. Check air supply.
y
Air motor is dirty or lacks lubrication. Clean air motor.
Insufficient air pressure or volume of air. Check air supply.
