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.(Seethe pump model manual for the proper Form

No.)

• This LOWER PUMP END MANUAL is one of four documentsneed-

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--Checkdesign provides far easy priming of thelower 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 damagedseals. 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 by tightening the packing nut. Check for worn upper packings and replace them as necessary.
