GENERAL
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.
DESCRIPTION
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.

NPT
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 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.

Materialsandsolvents being pumped bythispump must be compatiblewith
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.
Usegrounded hoses (static wire) and be sure the object is grounded if it can
produce a static charge.
AIR
AND LUBE REQUIREMENTS
OPERATING INSTRUCTIONS
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 inĆ jury 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
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.
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.
PUMP
NOTE: All threads are right hand. CAUTION: DO NOT mar finish on (5) tube.
1. Clamp pump assembly in a vise on the air motor base assembly.
2. Unscrew (5) tube and pull down on the lower pump assembly. Set lower pump assembly aside.
3. Place a wrench on flats of the air motor piston rod and unscrew (7) follower from rod. Set (7) follower assembly aside. Remove (6) set screw.
4. Remove (4) washer, (3) spring and (2) washer. Refer to air motor manual if (1) seal needs to be replaced.
5. Clamp the lower pump assembly in a vise on the (15) seat. UnĆ screw (5) tube from (15) seat.
6. Remove (12) pin and (14) ball from (15) seat. Inspect ball and seat for damage.
7. Vise (7) follower and unscrew (11) seat. Remove (10) washer, (9) cup packing and (8) ball. Inspect ball and seat for damage.
