• TheChop--Check designprovides fareasypriming ofthe lowerfoot
valve. The double acting feature is standard in all ARO industrial
pumps, material is delivered to the pump discharge outlet on both
the up and down stroke.
PUMP RATI0 X REGULATED = MAXIMUM FLUID PRESSURE
PRESSURE
• The pump ratio is an expression ofthe relationshipbetween theair
motor area and the lower pump end area. EXAMPLE: When 150
PSI (10.3 Bar) air pressure is supplied to the pump motor on a 3:1
ratio pump,the lower pump end willdevelop a maximum of450 PSI
(31Bar)fluidpressure(atnoflow).Asthefluidcontrolisopened,the
flow rate will increase as the motor cycle rate increases to keep up
with the demand.
• Operating at excessive pressures will shorten the life of the pump.
TROUBLE SHOOTING CHOP- CHECK PUMPS
Lower Pump End Problems
• No material at outlet. (Pump continually cycles.)
Check material supply, disconnect or shut off the air supply and re-
plenish the material, reconnect.
