This LOWER PUMP END MANUAL is one of four documents need-

ed to properly support an ARO pump model.

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.

Copies are available from the factory upon request.

•

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.

•

The pump ratio is an expression of the relationship between the air

motor area and the lower pump end area.

REGULATED INLET AIR PRESSURE X PUMP RATI0 =

MAXIMUM FLUID OUTLET PRESSURE PRESSURE

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 (31 Bar) fluid pressure (at no flow).

As the fluid control is opened, 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

Common 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 by tight-

ening the packing nut.

Check for worn upper packings and replace them as necessary.
