OPERATING AND SAFETY PRECAUTIONS
WARNING

EXCESSIVE INLET PRESSURE. Can cause explo-

sion, resulting in severe injury or death. Do not exceed

maximum operating pressure of 7500 p.s.i. (517 bar) at 150

p.s.i. (10.3 bar) inlet pressure. Do not run pump without us-

ing a regulator to limit air supply pressure to the pump.

WARNING

EXCESSIVE MATERIAL PRESSURE. Can cause

equipment failure, resulting in severe injury or property

damage. Do not exceed the maximum material pressure of

any component in the system.

Replacement warning label (pn 94520) is available upon re-

quest.

Pump Ratio X = Maximum Pump
Inlet Pressure to Pump Motor Fluid Pressure
Pump ratio is an expression of the relationship between the pump motor area
and the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure
is supplied to the motor of a 4:1 ratio pump, it will develop a maximum of 600 p.s.i.
(41.4 bar)  uid pressure (at no  ow) - as the  uid control is opened, the  ow rate
will increase as the motor cycle rate increases to keep up with the demand.
WARNING

Refer to the general information manual in-

cluded for additional operating and safety precautions and

other important information.

NOTICE: Thermal expansion can occur when the  uid in the mate-

rial 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.
