We manufacture pneumatic barrel pump for various industrial use. This is an automatic Operational Air driven Pump. There is a telescopic shaft which is put in lubricant container and once air is given the pump starts and the piston in the cylinder moves up and down, due to which the lubricant is given out. The flow can be made to stop by the stopping the flow of air. Hence, this pump can be intermediate in operation by using a Timer and Solenoid Valve to ‘ON’ and ‘OFF’ the pump. For Grease a follower plate is required and a spring helps for suction of the grease, however, for oil this is not required. The length of the shaft is dependent on the height of the container on which the pump is mounted. The air pressure required to operate the pump is minimum 3 kg/cm3 and max 12 kg/cm3. The ratio of air to lubricant is 1: 25 i.e. if the air is say 5 kg/cm3 then the lubricant pressure (under Stress) will be 125 kg/cm3 hence this will flush out any contamination if present in the system.
This pneumatic barrel pump is widely used to transfer lubricant and also for systems where the lubricating points is large in number. These barrel pumps find application in all types of machines and equipment and also in garages for lubrication of vehicles. The flow can be adjusted by adjusting the flow of air. The supply of air has to be through a Filter and Lubricator, so that dirt, moisture etc. do not enter the pump and the pump works for a long life.
