OPERATINGINSTRUCTIONS
LEAFLET
Air-operated Grease Pump
(1) Instructions
(a) The pump is a reciprocating pump with double
action desing allows fordispensing product on both
the up stroke and down stroke to provide steady
and continuous delivery.
(b) Two strokes only one exhasust at down stroke
dead point.
(c) With 50 to 1 pressure ratio, i.e. use 5 kg/sq.cm
(70 psi) air input pressure then can get 250 kg/
sq.cm (3500 psi) fluid output pressure.
CAUTION
Always keep lubricants clean and covered to prevent
dirt damaging bearing of equipment or clog the pump.
WARNING
Never run pump with air motor plate removed.
(2) Specifications
(a) 4-1/4’’ I.D., 2-3/4’’ stroke air motor.
(b) Pressure ratio: 50:1
(c) Recommended operating pressure: 5-8 kg/sq.cm
(70-115 psi)
(d) Delivery rate: 2.24 kgs per minute at 6 kg/sq.cm
(e) Capacity: suitable for 180 kgs original drum.
a. 4-1/4’’I.D.Air Motor
b. Quick DetachAir Coupler
c. Fluid Outlet Connector
(3) Operation
(a) Joint the air line intoAir Coupler
(b) If useAir Pressure Regulator, set the pressure within 5-8 kg/sq.cm (70-115 psi) and will get 250-400 kg/sq.cm (3500-
5750 psi) fluid output pressure.
(c) The Pump will stop automatically when the resultant force at two terminals of Pump are in equilibrium.
(d) If your air line system doesn’t set oiler for lubricating air. For daily, manual lubrication, disconnect the Quick DetachAir
Coupler, place about 15 drops of light machine oil in the air inlet, reconnect the hose and turn on the air supply to blow
oil into the Motor.
(e)Always turn off power to Pump and release all pressure in system before disconnecting or servicing anyparts of system.
At reassembly, be sure to tighten all threaded connections securely.
(f)Never allow the Pump to run dry of material.AdryPump will quickly accelerate to a high speed, possiblydamaging itself.
If your Pump accelerate quickly or is running to fast, stop it immediately and check the material supply. If the supply
container is emptyand air has been pumped into line, prime Pump and line with material.

(4) TROUBLE DIAGNOSIS
(I) When Pump runs.
(A) Low output pressure or delivery.
(a) On up stroke - 1.Check 19 (fig.3) Valve seat within 6 (fig.3) Coupling.
2.Check 10 (fig.3) Packing.
(b) On down stroke - 1.Check 19 (fig.3) Valve Seat within 13 (fig.3) Check Valve Packing Retainer.
2.Check 12 (fig.3) Packing & 11,12 (fig.3) Guide.
(c) On both strokes - 1.Insufficient air pressure - Increase air pressure.
2.Refer to (I) (B).
3.Refer to (I) (A) (a) & (I) (A) (b).
4.Replace 8 (fig.3) Guide, 9 (fig.3) Washer, 10 (fig.3) Packing, 11 (fig.3) Guide, 12 (fig.3)
Packing & 14 (fig.3)Guide. If 34 (fig.2) Packing or 33 (fig.2) Bearing worn-out, replace
it.
(B) No lubricant delivery
(a) Lubricant drum may be empty - Replenish lubricant or replace with new lubricant drum.
(b) Lubricant is too heavy to absorb - Use 81921 or 81922 Follower Plate (to be ordered separately) or thin it
with clean machine oil.
*(c)The Fluid line within Pump is being clogged by foreing matter.
- Clean the fluid line of 6 (fig.3) Coupling, 13 (fig.3) Check Valve Packing
Retainer, 15 (fig.3) displacement Tube.
(II) When Pump fails to run
(A) Continuous air leakage from exhaust.
CheckAir Motor - Check 24 (fig.2) Lockwire, 11 (fig.2) Stem Valve, 25 (fig.2)Adjusting Nut, 28 (fig.2) Puppet
Rubber Valve, 12 (fig.2) O-ring & 16 (fig.2) O-ring.
(B) No air leakage.
(a) Check air supply line - 1.Air line is being clogged.
2. Insufficient air pressure - Increase air pressure.
*(b) Pump is stopped by foreing matter between 18 (fig.3) Priming Tube & 17 (fig.3) Priming Plunger.
- Loosen 18 (fig.3) Priming Tube and clean 15 (fig.3) Displacement Tube, 18 (fig.3)
Priming Tube, 17 (fig.3) Priming Plunger.
*A 40651 Strainer is recommended to prevent foreing matter clog Pump.
(5) MAINTENANCE
The pump will be reparaid by replacement or adjustment for only the necessary parts in judgement from out-looking
troubles onthe pump and unnecessarydisassemblyshould be avoided. In some long time use, it mayberequired to overhaul
the pump so as to remedy decreasing efficiency caused by worn packing and others. If you are using a repair kit to service
the pump, use new parts, even if the old one look good. The old parts will wear faster making pump service needed again
sooner. Use 40650 Repair Pack forAir Motor, 8040660 Repair Pack for Displacement Tube.

(6) DISASEMBLY AND REASSEMBLY
(a) For Displacement Pump ( fig.3).
Clamp 18 (fig.2) Air Motor Base in a vise and screw 18 Priming Tube off 16 Packing Retainer. Put a rod through
the hole of 15 Displacement Tube and screw 17 Priming Plunger off 15 Displacement Tube. Loosen 16 Packing
Retainer then use a pipe wrench at the knurl part of 4 Displacement Cylinder to screw it out of 18 (fig.2)Air Motor
Base and remove it. Screw 16 Packing Retainer out of 4 Displacement Cylinder and remove 11&14 Guild and 12
Packing. Use a hammer and punch to remove 2 Roll Pin from 13(fig.2)Air Piston Tube then screw 1 Connecting
Rod out of 13 (fig.2) Air Piston Tube. Use a rod to screw 15 Displacement Tube out of 13 Check Valve Packing
Retainer. Remove 7 Gasket, 19 Valve Seat and 5 Steel Ball, then screw 13 Check Valve Packing Retainer out of
6 Coupling and remove upper 7 Gasket, 19 Valve Seat and 5 Steel Ball. Remove 8 Guide, 9 Washer, 10 Packing.
Clean all parts and inspect them for wear or damage. Replace parts as necessary. Lubricate all parts with light
waterproof grease and reassembly the Pump. To reassembly, make sure of assembling in reverse order o f
disassembling method. Be sure to tighten securely.
(b) For Air Motor ( fig.2).
Clamp 18 Air Motor Base in a vice. Unscrew 1 Cylinder Cap Nut. Pull Nut up, grip 7 Trip Rod with padded pliers
and screw 1 Cylinder Cap Nut off rod. Use a nut (5/16’’-18 UNC). Screw in 7 Trip Rod. Remove 19 Bol t
holding 3 Cylinder to the base and carefully pull 3 Cylinder Straight up off 10 Piston. Unscrew nut (5/16’’-18
UNC) off 7 Trip Rod then screw 1 Cylinder Cap Nut in 7 Trip Rod. Press 1 Cylinder Cap Nut push down on 6
Shuttle to snap the 23 Toggle Arm down. Remove 24 Lockwire from 25 Adjusting Nut, screw the top nuts of 25
Adjusting Nut off and screw 11 Stem Valve off 27 Grommets and bottom nuts of 25 Adjusting Nut. Press 1
Cylinder Cap Nut and put a screw driver under the 23 Toggle Arm, lever it up slowly and carefully. Pull 10 Piston
up out of 18 Air Motor Base, remove 32 Throat Packing Nut and take out the 33 Bearing, 34 Packing and 35
Gland. Clean all the parts carefully and inspect for wear or damage. Replace parts as necessary. Che ck the
polished surface of 10 Piston, 13 Air Piston Tube and 3 Cylinder wall for wicks, mars or scratches. Lubricate all
parts with a light, waterproof grease and reassembly the Air Motor. To reassembly, make sure of assembling in
reverse order of disassembling method.
