SERVICE KITS

• Use only genuine AROR replacement parts to assure compatible

pressure rating and longest service life.

• 637066-B for repair of Air Motor section.

• Order individual parts for repair of Lower Pump section.

GENERAL

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.

DESCRIPTION

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

and lower pump end.

RATIOx REGULATEDAIR 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 PRESSUREOF 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 pumpiscapable 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.

• Donot operate pump continuouslyatspeeds in excess of75 cycles 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.

• Usegrounded 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.

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

ods of time.

AIR

AND LUBE REQUIREMENTS

WARNING HAZARDOUS PRESSURE. Do not exceed maxiĆ

mum inlet air pressure of 150 psi (10 bar). Operating pump at higher pressure may cause pump damage and/or personal injuĆ ry and/or property damage.

• Refer to general information sheet for additional safety precauĆ

tions and important information.

• Excessive air pressure will shorten the life of the pump.

• For maximum operating efficiency, the following air supply specifiĆ

cations should be maintained to this pump.

• AIR PRESSURE - Up to 150 P.S.I. (10 Bar)

• AIR FILTRATION - 50 micron

• LUBRICATED AIR SUPPLY

• AIR INLET SIZE - 1/4" NPTF

• Filtered and oiled air will allow the pump to operate more efficiently

and yield a longer life to operating parts and mechanisms.

• Lack of or an excessive amount of lubrication will affect the perforĆ

mance and life of this pump. Use the recommended lubricants.

• DAILY: Fill air line lubricator with a good grade of S.A.E. NO.

90 W non-detergent gear oil, adjust to 1 to 2 drops per minute.

• If pump is to be inoperative for more than a few hours at a time,

disconnect air supply and relieve all pressure from the system.

It is recommended that an oiler be installed in the airline as close as possible to the pump. This increases the service life of the pump by reducing wear of the air motor's internal parts.

INSTALLATION

OPERATING INSTRUCTIONS

1. Turn air regulator knob clockwise until air motor starts to cycle.

2. Allow pump to cycle slowly until it is primed and all air is purged from the fluid hose or dispensing valve.

3. Turn off dispensing valve and allow pump to stall-check all fittings for leakage.

4. Change air regulator setting until desired pressure and flow is obĆ tained.

5. Inspect airline filter, open petcock to flush moisture or residue from bowl.

6. Pump is recommended to operate between 30 PSI and 150 PSI (not to exceed 75 cycles per minute.)

MAINTENANCE

The basic pump consists of two major components: 1. Air Motor, 2. Lower Pump. The air motor is removable and is to be serviced sepaĆ rately. Refer to air motor manual for service and parts.

• Periodically flush entire pump system with a solvent that is comĆ

patible with the material being pumped.

• Refer to disassembly procedures of air motor for correct breakĆ

down.

• Disassembly should be done on a clean work bench with clean

cloths to keep parts clean.

• If replacement parts are necessary, consult drawing containing

parts for identification.

• Before assembling, lubricate parts where required. When assemĆ

bling ``O" rings or parts adjacent to ``O" rings, care must be exerĆ cised to prevent damage to ``O" rings and ``O" ring groove surfaces.

FLUSH PUMP

1. Connect fluid hose to pump outlet and be sure all fittings are tight.

2. Turn air regulator knob counter-clockwise until it turns freely.

3. Pump has been tested in oil and a small amount remains for protection against rusting. Immerse lower pump end in compatible solvent.

4. Connect air hose coupler to connector on FRL.

5. Turn air regulator knob clockwise until air motor starts operating.

6. Flush pump with oil.

7. Disconnect air supply from air motor.

• CAUTION: Solvent used for flushing may not be compatible with

material being pumped. If this is the case, flush again with a comĆ patible solvent.

• If pump is to be inoperative for an unspecified period of time, disĆ

connect air and relieve all pressure.

• If pump does not function properly, disconnect air and relieve all

pressure. Refer to Trouble Shooting.

PUMP

NOTE: All threads are right hand. CAUTION: DO NOT mar finish on (10) or (22) tube.

1. Clamp pump assembly in a vise on the air motor base assembly.

2. Place a strap wrench around (4) tube and loosen by turning counĆ terclockwise. If the wrench slips on the (4) tube, wrap a piece of 400 sand paper around (4) tube and under strap wrench. (Note: Pipe wrench will damage the finish of the tube.

3. After the (4) tube has been pulled down to expose the (2) rod, hold air motor piston rod and unscrew the (2) rod from the air motor pisĆ ton rod.

4. Remove the air motor assembly from the vise.

5. Vise the lower pump and remove (22) primer tube from (10) tube.

6. Remove (21) cotter pin, (20) primer, (19) seat, (18) washer, (17) spacer, (16) body assembly (Disassemble body assembly if (14) ``u" cup or (15) spacer needs to be replaced.) and (12) washer from assembly.

7. Remove (10) tube from (4) tube. Remove (5) gasket.

8. Pull rod assembly from (10) tube and disassemble (9) adapter from (7) plunger to remove (8) ball.
