GENERAL DESCRIPTION
The two-ball pumps are primarily designed for the high volume
transfer of light and medium viscosity fluids. Stainless steel con-
struction off ers compatibility with a wide range of fl uids. The lower
pump is designed for easy priming and 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 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 leak-
age through the material packing gland. Be sure the solvent cup is
adequately fi lled with lubricant to protect the upper packings and
insure longest service life.
WARNING HAZARDOUS PRESSURE. Do not exceed maxi-
mum operating pressure of 1350 p.s.i. (93.1 bar) at 90 p.s.i.
(6.2 bar) inlet air pressure.
Pump Ratio X = Maximum Pump
Inlet Pressure to Pump Motor 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 4:1 ratio pump, it will develop a maximum of 600
p.s.i. (41.4 bar) fl uid pressure (at no fl ow) - as the fl uid control is opened, the fl ow
rate will increase 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.
NOTICE: Thermal expansion can occur when the fl uid in the mate-
rial lines is exposed to elevated temperatures. Example: Material
lines located in a non-insulated roof area can warm due to sunlight.
Install a pressure relief valve in the pumping system.
Replacement warning label (pn 92325) is available upon re-
quest.
TROUBLE SHOOTING
Pump problems can occur in either the air motor section or the
lower pump end section. Use these basic guidelines to help deter-
mine which section is aff ected.
Pump will not cycle.
Be certain to first check for non-pump problems including
kinked, restrictive or plugged inlet / outlet hose or dispensing
device. Depressurize the pump system and clean out any ob-
structions in the inlet / outlet material lines.
Refer to the motor manual for trouble shooting if the pump
does not cycle and / or air leaks from the air motor.
Damaged motor. Service the motor.
Pump cycles but does not deliver material.
Refer to the lower pump end manual for further trouble shoot-
ing.

PUMP CONNECTION - UPPER / LOWER
NOTE: All threads are right hand.
Lay the pump assembly on a work bench.
Remove the three (Y6-128-C) cap screws and (Y14-750-K) lock
washers from the three spacer rods (see fi gure 1).
Pull the air motor from the lower pump end until the motor
piston rod is in the “down” position and the lower pump end
rod is in the “up” position.
Remove the three spacer rods by removing the three (Y6-
128-C) cap screws and (Y14-750-K) lock washers.
Using e-ring pliers, slide the “e” ring up far enough to allow the
sleeve to move upward and release the two connectors (see
fi gure 2).

REASSEMBLY
Align the pump motor with the lower pump end. Position the
air inlet of the motor 180° from the material outlet.
Install the two (94688) connectors and retain with the (94689)
sleeve. Slide the (95069) “e” ring back into position.
Assemble the three (93866) spacer rods to the lower pump
and secure using three (Y14-750-K) lock washers and (Y6-
128-C) cap screws.
Reinstall the spacer rods to the pump motor.
Bring the motor and lower pump together and retain with
three (Y14-750-K) lock washers and (Y6-128-C) cap screws.
