SERVICE KITS

•

Use only genuine ARO

R

replacement parts to assure compatible

pressure rating and longest service life.

•

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 withstandĆ

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.

OPERATING AND SAFETY PRECAUTIONS

•

HEED ALL WARNINGS.

•

DO NOT EXCEED MAXIMUM WORKING PRESSURE OF 786 PSI (54

BAR) AT 150 PSI (10 BAR) AIR INLET PRESSURE.

WARNING

: HIGH PRESSURE DEVICE. Improper usage of

this equipment could result in serious injury. The possibility

of injection into the flesh is a potential hazard. Never allow any

part of the human body to come in front of or in direct contact

with the material outlet. An injection injury can be serious. If

injection should occur, contact a qualified physician immediĆ

ately for treatment.

•

COMPONENTRUPTURE.

This pump is capable of producing high material

pressure as stated on pump model plate.

•

Be sure material hoses and other components are able to withstand fluid

pressures developed by this pump.

•

Do not operate pump continuously at speeds in excess of 75 cycles per minĆ

ute.

•

Disconnect air line from pump air motor when system sits idle for long periĆ

ods of time.

•

Materials and solvents being pumped by this pump must be compatible with

the parts of this pump that come in contact with the material and solvent.

WARNING

: PREVENT STATIC SPARKING. If static sparking

occurs, fire or explosion could result. Pump, dispensing

valve and containers must be grounded when handling inĆ

flammable fluids such as petroleum products, paints, lacĆ

quers, etc. and wherever discharge of static electricity is a

hazard.

•

Use grounded hoses (static wire) and be sure the object is grounded if it can

produce a static charge.
