WORKING OF PUMP
OPERATION & USE
The pump has a spring loaded wave action mechanism installed at the bottom of the bucket.
1. Fill correct grade grease into the pump bucket. 2. Tamp the bucket on a firm surface to push the grease to displace air pockets trapped in the cavities in the base of the bucket.
Pressing the foot lever makes a cylinder to move forward leaving empty space behind it. The grease due to its weight fills this empty space.
3. Operate the pump by pressing the foot lever a few times until delivery commences. 4. Now the pump is ready for dispensing. When not in use, the pistol handle can be put into the nozzle holder provided at the side of the foot lever.
Cylinder in open position Spring Loaded Mechanism On releasing the foot lever, the cylinder returns to its original position pushing the accumulated grease into a hollow piston that throws the grease from the pump outlet into delivery hose. Cylinder in closed position
PUMP DISASSEMBLY & REASSEMBLY (Refer to Parts Drawing) 1. Unscrew Grease Hose (20) from Holder Assembly (15). 2. Remove four Bolts (3) & remove Rest Pad (2). 3. Open drum cover & remove four Nyloc Nuts (18). Remove both Extension Springs (1) using a spring pullar. 4. Remove Holder Assembly (15) & its Rubber Seal (19). Pull out Piston (12) from the assembly. Remove Grub Screw (16) from Holder Assembly (15) to remove Piston Spring (14) & Steel Ball (13). 5. Remove Plunger & Bracket Assembly (4) from grease bucket. Remove Cotter Pin (5) to separate Plunger &
Hollow Piston
Subsequent strokes of the foot lever fill the delivery hose & discharge begins from the pistol handle.
PRIMING THE PUMP
Bracket Assembly (4) from Pusher Bracket (17). Unscrew Non Return Body (7) to remove Steel Ball (8) & Plunger Spring (9). 6. Assemble by following the steps 1-5 in reverse order taking particular care of the points given below:
Priming is getting the pump started by operating foot lever for 3-4 minutes until grease gets dispensed from the the pistol handle. Always PRIME the pump when using it for the FIRST time.
• Steel Ball (8) must rest evenly on its seat over Non Return Body (7). Also, Steel Ball (8) must rest on the narrower edge of Plunger Spring (9) otherwise the ball will fall into the spring causing pump failure. • Always lubricate O-rings and seals with grease before fitting. They must be protected from sharp edges when being fitted. Lubricate all moving parts with grease. • When troubleshooting, be on a lookout for dirt in valves / ball seats, damaged O-ring / seal & scratches in sealing surfaces. • Apply thread sealant to ensure leak-proof operation.
When working in cold weather or using a thicker grease, keep grease thin for easy workability in one of the following ways: • Mix some oil (SAE30) with grease. Shake the bucket & press the mixture thoroughly to remove any air pockets • Heat grease bucket with a Barrel Warmer or Heating Jacket. The temperature should be kept at 0 - 30°C (32 - 86°F)
While filling grease for the first time: • Do ensure that grease is well settled down. • Use steel plate or press grease by hand (use plastic gloves and then lift and tap the bucket on the ground 5 to 6 times to allow the grease to settle and drive out big air pockets).
