SERVICE KITS

• Use only genuine AROR replacement parts to assure compatible

pressure rating and longest service life.

Air Inlet 2608 Connector

• 637066-B for repair of Air Motor section.

GENERAL DESCRIPTION

This model is designed for high volume delivery of low viscosity fluids such as motor oil, gear oil or transmission fluids. Material dispensing accessories and supply lines and fittings must be capable of withstand$ ing pressures developed by pump.

• The ARO 5:1 ratio basic pump assembly consists of a 3" air motor

and ball check lower pump end.

• The ball check design provides for easy priming of the lower foot

valve. Material is delivered to the pump discharge outlet on both

the up and down stroke.

RATIO x REGULATED AIR PRESSURE TO AIR MOTOR = MAXIMUM FLUID PRESSURE.

•The 5:1 ratio is an expression of the relationship between the air motor area and the lower pump end area. When 150 p.s.i. (10 bar) air pressure is supplied to the air motor, the lower pump end will develop a maximum of 786 p.s.i. (54 bar) fluid pressure (at no flow) - as the fluid control is opened, the flow rate will increase as the air motor cycle rate increases to keep up with the demand.
