GENERAL DESCRIPTION

The two-ball pumps are primarily designed for the high volume

transfer of light and medium viscosity fl uids compatible with car-

bon steel. The lower pump is designed for easy priming and the

double acting feature is standard in all ARO industrial pumps. Ma-

terial 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.

HAZARDOUS PRESSURE. Do not exceed maxi-

WARNING

mum operating pressure of 5850 p.s.i. (403.4 bar) at 90 p.s.i.

(6.2 bar) inlet air pressure.

Pump Ratio X

Inlet Pressure to Pump Motor

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.

Refer to general information sheet for additional

WARNING

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).

PUMP CONNECTION DETAIL

REASSEMBLY

Align the pump motor with the lower pump end. Position the

air inlet of the motor in line with 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.
