Pneumatic
Pump
Application
The
pneumatic grease pump is suitable for dispensing of grease and
automatic feeding of grease and automatic feeding of grease to bearing
and other moving parts of machines. Such as milling machine rolling
machine, pressure and hammers, rubber processing machine, dye casting
machine, furnaces etc. The pump is suitable for grease upto NLG-2. For
distribution we used progressive blocks through this pump.
Working
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.
Air
Removing
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 operation.
Construction
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.
Filling
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.
