Detail view of manual grease pump
Application
This pump meant for feeding grease to bearing & other moving part of machines & other lightly machines having 1to 20 lubrication point.
Working
On pulling the handle of pump, grease are sucked through suction port on pushing handle of pump grease comes out under pressure through check value. Spring pressure through follower plate exerted over the top surface of the grease further helps to push the grease in suction port.
Equipment
Pump is made up of purely transparent acrylic reservoir for storage of grease. For sensing the Grease level a tell tale rod is provide and follower plate assembly for help in positive suction of grease. It contains two outlet part of ¼” BSP right and left side in which one is used as air bleed valve and second port used as a outlet. To check reverse flow of grease, a non return valve is provide in the system at the outlet port.
Filling Of Grease
Grease can be filled manually or with another pump. Filling from pump ¼” BSP port is provide. Manually, we have to remove follower plate, spring, top cover and fill the grease from the top of the reservoir and to fit all the components by pressure . For air removing unscrew the bleed plug pull the handle maximum out and press the follower plate by knob till grease comes out from bleed plug.
Distribution System
A Progressive block is used to distribute the grease to the available lubrication points in sequence one after another. Progressive Blocks are added as per requirement.

When to Use a Manual Grease Pump
A manual grease pump is the most cost-effective solution for machines with a small number of lubrication points (1 to 20) that do not require automatic or continuous lubrication cycles. The operator activates the pump by pulling and pushing the handle at scheduled maintenance intervals — each stroke delivers a precise, fixed volume of grease to the distribution line.
Because there is no motor or controller, manual grease pumps require no electrical connection and have minimal maintenance requirements. They are ideal for small machine tools, presses, packaging machines, and workshop equipment where automation is not justified.
Manual vs Pneumatic Grease Pump — Which to Choose?
| Feature | Manual Grease Pump | Pneumatic Grease Pump |
|---|---|---|
| Operation | Hand lever — operator driven | Compressed air — automatic |
| Lubrication points | 1 to 20 | Up to 50+ |
| Cycle frequency | Manual — at maintenance intervals | Timed — automatic cycles |
| Power required | None | Compressed air (5–7 kg/cm²) |
| Cost | Low | Higher |
| Best for | Small machines, infrequent lubrication | Heavy machinery, frequent cycles |
