GENERAL DESCRIPTION
WARNING HAZARDOUS PRESSURE. Do not exceed maxi
mum operating pressure of 1200 p.s.i. (82.8 bar) at 120 p.s.i. (8.3
bar) inlet air pressure.

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 120 p.s.i. (8.3 bar) inlet pressure is supplied to
the motor of a 5:1 ratio pump it will develop a maximum of 600 p.s.i. (41.4 bar) fluid pres
sure (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.

WARNING Refer to general information sheet for additional
safety precautions and important information.
The TwoBall pumps are primarily designed for the high volume
transfer of light and medium viscosity fluids. Stainless Steel
construction offers compatibility with a wide range of fluids. The low
er 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 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.

NOTE: All threads are right hand.
1. Lay the pump assembly on a workbench.
2. Remove the three (Y6128C) cap screws and (Y14750K) lock
washers from the three spacer rods (figure 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. Remove the three spacer rods by removing the three (Y6128C)
cap screws and (Y14750K) lock washers.
5. Using ering pliers, slide the ‘‘e" ring up far enough to allow the
sleeve to move upward and release the two connectors (figure 2).

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.
• Be certain to first check for nonpump 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.
• 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.
• Refer to the lower pump end manual for further trouble shooting.

REASSEMBLY
1. Align the pump motor with the lower pump end. Position the air inlet
of the motor 180_ from the material outlet.
2. Install the two connectors and retain with the sleeve, slide the ‘‘e"
ring back into position.
3. Assemble the three spacer rods to the lower pump and secure using
three (Y14750K) lock washers and (Y6128C) cap screws.
4. Reinstall the spacer rods to the pump motor.
5. Bring the motor and lower pump together and retain with three
(Y14750K) lock washers and (Y6128C) cap screws.
