Manual Grease Pumps

Additional Details

Operational Theory
The hand operated grease pumps provide a predetermined quantity of grease on each stroke of its operation, when we pull the hand suction part of the cylinders it gets filled with grease, spring force through follow plate on the top surface further helps to push grease into the suction part. While pushing handle this grease comes out under pressure through check valve and is supplied by the lubricating points through pipelines.

Device
These hand operated grease pump is made up of purely transparent acrylic reservoir for storage of grease. For sensing the Grease a tell tale rod is used and follower plate assembly help in positive suction of grease. These hand operated pumps contains two outlet part of 1/4” Bsp right and left side in which one is plugged and used as Air Bleeding Valve

Filling of Grease
Grease can be filled manually and with another pump for which V/BSP port is provided. Manually, we have to remove follower plate, spring and top cover and fill the grease from the top of the reservoir and to fit all the components by pressure.

Grease Distribution to Lubrication Points
A Progressive block is used to distribute the grease to the available lubrication points sequentially and in a predetermined quantity. Progressive Blocks are added as per requirement.

Precaution
While using this manual grease pumps we should take precaution to avoid entering of foreign / dust particles in grease. If it is present in the grease it will result in physical damage of the pump parts. Secondly grease should be tightly packed to avoid air pockets. Air pockets are an obstacle in providing proper quantity of grease. A bleed plug is present in the pump to remove it. Last but not least manual grease pumps should be inspected regularly especially for air pockets and purity of grease.
