air operated grease filling system

We manufacture Pneumatic Pumps which are highly durable as well as reliable. These grease pumps are designed according to the technical specifications provided by the client. Our pumps are also corrosion resistant and require less maintenance.


The pneumatic grease pump is suitable for dispensing of grease and automatic feeding of grease to bearing and other moving parts of machines. Such as milling machine rolling machine, presses and hammers, rubber processing machine, die casting machine, furnaces etc. The pump is suitable for grease upto NLG-2. For distribution we used progressive blocks through this pump.


Pneumatic grease pump are operated through pneumatic line, connected to the ports of pneumatic cylinder. The cylinder is built in with the pump housing. Druign on period of the pneumatic line a piston inside the cylinder is pushed ejecting out grease from the outlet port of the pump housing. During the reverse flow of pneumatic line grease is sucked through the suction port. In the pump spring force through follower plate exerted on the top surface of the grease make the suction of the grease positive and easier. Pneumatic pump is available in adjustable discharge and multi port with adjustable discharge in each port. Discharge and reservoir of pump is available as per customer requirement.


For air removing, un screw the bleed plug apply compressed air and press the grease pusher by knob till grease come out from bleed port and plug the bleed port. The pump is ready for peration.


There is a reservoir mounted on the pump body for storage of grease. A tell tale rod connected for sensing grease level.

  • Check valves is fitted on the outlet port of the pump to stop reverse flow of grease into the pump through outlet port.
  • To bleed air entrapped in the system, there is a plug on the pump body which is to be opened fill continuous flow of grease starts coming.
  • The adjusting screw is provided in order to vary in output of the grease by tightening the screw the output of grease decreases and vice versa.
  • It is must to put filter regulator unit in the pneumatic line fed to the pump. This will ensure that pneumatic line going to the pump is dust and moisture free.

Grease filling in the reservoir can be done manually as well as with the help of other pump. For these who wants to fill grease by another pump, a 1/4" BSP ports is provide on front side of the pump. This port is normally plugged.
