OPERATING AND SAFETY PRECAUTIONS
WARNING EXCESSIVE INLET PRESSURE. Can cause ex-
plosionresulting in severe injury or death. Do not exceed maxi-
mum operating pressure of 7500 p.s.i. (517 bar) at 150 p.s.i.
(10.3 bar) inlet air pressure. Do not run pump without using a
regulator to limit air supply pressure to the pump.
WARNING EXCESSIVEMATERIAL PRESSURE. Can cause
equipment failure resulting in severe injury or property dam-
age. Do not exceed the maximum material pressure of any
component in the system.
Replacement warning label is available upon request, PN \ 94520.
PUMP RATIO X
INLET PRESSURE TOPUMP MOTOR =MAXIMUM PUMP
FLUID PRESSURE
Pumpratio is an expression of the relationship between the pump motor area and
thelower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is
suppliedto the motor of a 50:1 ratio pump it willdevelop a maximum of 7500 p.s.i.
(517bar)fluid pressure (at no flow) --as the fluid control is opened, the flow rate will
increaseas the motor cycle rate increases to keep up with the demand.
NOTICE:Thermal expansion can occur when the fluid in the materi-
al lines is exposed to elevated temperatures. Example: Material
lineslocated in a non-insulated roof area can warm due to sunlight.
Install a pressure relief valve in the pumping system.
