Ingersoll-Rand 66650 AIR and Lube Requirements, Installation, Operating Instructions, Maintenance

AIR AND LUBE REQUIREMENTS

WARNING HAZARDOUS PRESSURE. Do not exceed maxi! mum inlet air pressure of 150 psi (10 bar). Operating pump at higher pressure may cause pump damage and/or personal inju! ry and/or property damage.

•Refer to general information sheet for additional safety precau3 tions and important information.

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

•For maximum operating efficiency, the following air supply specifi3 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 perfor3 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 com3 patible solvent.

•If pump is to be inoperative for an unspecified period of time, dis3 connect air and relieve all pressure.

•If pump does not function properly, disconnect air and relieve all pressure. Refer to Trouble Shooting.

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 ob3 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 sepa3 rately. Refer to air motor manual for service and parts.

•Periodically flush entire pump system with a solvent that is com3 patible with the material being pumped.

•Refer to disassembly procedures of air motor for correct break3 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 assem3 bling ``O" rings or parts adjacent to ``O" rings, care must be exer3 cised to prevent damage to ``O" rings and ``O" ring groove surfaces.

PUMP DISASSEMBLY

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 coun3 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 pis3 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.
