GENERAL DESCRIPTION
WARNING HAZARDOUS PRESSURE. Do not exceed maxi-
mum operating pressure of 3300 p.s.i. (228 bar) at 150 p.s.i.
(10.3 bar) inlet air pressure.
PUMP RATIO X
INLET PRESSURE TO PUMP MOTOR
= MAXIMUM PUMP
FLUID PRESSURE
Pump ratio is an expression of the relationship between the pump motor area and
the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is
supplied to the motor of a 6:1 ratio pump it will develop a maximum of 750 p.s.i. (52
bar) fluid pressure (at no flow) - as the fluid control is opened, the flow rate will in-
crease as the motor cycle rate increases to keep up with the demand.
WARNING Refer to general information sheet for additional
safety precautions and important information.
x The Two-Ball pumps are primarily designed for the pumping of me-
dium viscosity fluids, Stainless Steel construction offers compatibili-
ty with a wide range of fluids. The two-ball design provides better
priming of the lower foot valve. The double acting feature is standard
in all ARO industrial pumps, material is delivered to the pump dis-
charge outlet on both the up and down stroke.
x The motor is connected to the lower pump end by a spacer section.
This allows for lubrication of the upper packing gland and prevents
motor contamination because of normal wear and eventual leakage
through the material packing gland. Be sure the solvent cup is ade-
quately filled with lubricant to protect the upper packings and insure
longest service life.
TROUBLE SHOOTING
Pump problems can occur in either the Air Motor Section or the Lower
Pump End Section, use these basic guidelines to help determine which
section is affected.
If the pump will not cycle.
x Be certain to first check for non-pump problems including kinked, re-
strictive or plugged inlet / outlet hose or dispensing device. Depres-
surize the pump system and clean out any obstructions in the inlet /
outlet material lines.
x Refer to the motor manual for trouble shooting if the pump does not
cycle and / or air leaks from the air motor.
If the pump cycles but does not deliver material.
x Refer to the lower pump end manual for further trouble shooting.
PUMP CONNECTION -- UPPER / LOWER
NOTE: All threads are right hand.
1. Lay the pump assembly on a workbench.
2. Remove the three nuts from the three spacer rods. (Fig. 1)
3. Pull the air motor from the lower pump end until motor piston rod is in
the “down” position and lower pump end rod is in “up” position.
4. Using e-ring pliers, slide the retaining ring up far enough to allow the
sleeve to move upward and release the two connectors. (Fig. 2)

REASSEMBLY
1. Align the pump motor with the lower pump end.
2. Install the two connectors and retain with the sleeve, slide the retain-
ing ring back into position.
3. Reinstall the spacer rods to the pump motor.
4. Bring the motor and lower pump together and retain with the three
nuts.
