GENERAL DESCRIPTION

The four-ball pumps are primarily designed for the high volume transfer of light and medium viscosity fluids. Stainless steel construction o ers compatibility with a wide range of  uids. The lower pump is designed for easy priming. 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 adequately  lled with lubricant to protect the upper packings and insure longest service life.

WARNING

mum operating pressure of 702 p.s.i. (48.4 bar) at 120 p.s.i. (8.3 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)  uid pressure (at no  ow) - as the  uid control is opened, the  ow rate will increase as the motor cycle rate increases to keep up with the demand.

WARNING

safety precautions and important information.

NOTICE: Thermal expansion can occur when the  uid in the material 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 request.

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 a 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 obstructions in the inlet / outlet material lines. Refer to the motor manual for trouble shooting if the pump

Align the pump motor with the lower pump end. Position the air inlet of the motor 45° from the material outlet.

Install the two (94688) connectors and retain with the (94689) sleeve. Slide the (95069) “e” ring back into position.

Reinstall the spacer rods to the pump motor.

Bring the motor and lower pump together and retain with three (Y85-29-C) nuts.

REASSEMBLY

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-
