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.

•

60520 for repair of Lower Pump section.

GENERAL DESCRIPTION

This model is designed for delivery of heavy viscosity fluids such as

chassis lubrication fluids. Material dispensing accessories and supply

lines and fittings must be capable of withstanding pressures developed

by pump.

•

The ARO 50:1 ratio basic pump assembly consists of a 3" air motor

and lower pump end.

RATIO x REGULATED AIR PRESSURE TO AIR MOTOR = MAXIMUM FLUID

PRESSURE.

•

The 50:1 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 7,500 p.s.i. (517 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 7,500 PSI (517

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 75cycles per minĆ

ute.

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.

•

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

grounded if it can produce a static charge.

•

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

ods of time.
