GENERAL DESCRIPTION
LOWER PUMP END
WARNING DO NOT EXCEED MAXIMUM OPERATING PRES-
SURE AS INDICATED ON PUMP MODEL PLATE
WARNING REFER TO GENERAL INFORMATION SHEET
FOR ADDITIONAL SAFETY PRECAUTlONS AND IMPORTANT
INFORMATION. (See the pump model manual for the proper Form

• This LOWER PUMP END MANUAL is one of four documents need-
ed to properly support an ARO pump model. Ref: Part A. 650XXX--
XXX--X MODEL (OPERATOR’S) MANUAL, Part B. GENERAL
INFORMATION, Part C. MOTOR (OPERATOR’S) MANUAL, Part
D. LOWER PUMP END (OPERATOR’S) MANUAL. These forms
are available from the factory if needed.
• The Chop--Check design provides far easy priming of the lower foot
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 of the relationship between the air
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 will develop a maximum of 450 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.
• Material on one stroke only. (fast downstroke.)
The lower check may not be seating in the foot valve. (See lower
pump disassembly) Remove the check from the foot valve, clean
and inspect the valve seat area. If check or foot valve are damaged,
replace.
• Material on one stroke only. (fast upstroke.)
• Check for worn or damaged seals. Replace the seals as necessary.
• Material leakage out of the solvent cup or material appears on the
pump plunger rod.
For Models (--X5X Only). Increase the load on the packings bytight-
ening the packing nut.
Check for worn upper packings and replace them as necessary.
