OPERATING AND SAFETY PRECAUTIONS
WARNING
EXCESSIVE INLET PRESSURE. Can cause ex-
plosion resulting insevereinjury ordeath. Donotexceed 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
EXCESSIVE MATERIAL 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 TO PUMP MOTOR
=
MAXIMUM PUMP
FLUID PRESSURE
Pump ratio isan expression oftherelationship between thepump motorareaand
the lower pumpend area. EXAMPLE: When 150p.s.i. (10.3 bar) inlet pressure is
supplied to the motor ofa 50:1ratio pumpit willdevelop amaximum of7500 p.s.i.
(517bar)fluidpressure(atnoflow) -- asthefluidcontrolisopened,theflowratewill
increase as the motor cycle rate increases to keep up with the demand.
NOTICE: Thermal expansioncan occur when thefluid in themateri-
al 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.
