Pneumatic pumps are used in feeding multifunction and lubrication greases from the barriers. They are designed using double piston system that can create multiple levels of pressure, which can generate a huge amount of power. The applications where it is mainly used in moving media through a cylindrical chamber, in moving liquid or refrigerant are oil and gas, pulp and paper, water treatment, fertilizer dosing, and food processing. To ensure the usage stipulations are met, read the instruction carefully and most importantly, observe those stipulations. However, here are a few problems that users encounter with pneumatic pumps, and their solution:
Problem: Pneumatic units are not running at all or very slowly?
It can cause either due to the low air pressure or the filter or muffler is dirty or obstructed. Try keeping the air pressure as 3 bars and clean the filter so there remains no chance of blockage.
Problem: Pneumatic pumps are running but operating extremely slow?
There are a couple of reasons to why you are experiencing this issue like foul Sieve, dented grease container, bubbles in the grease, stiff grease, or loss of friction in the delivery hose. The solution to it would be ensuring to clean the Sieve. In the case of dented grease, press the follower plate from where it is bended. To reduce air bubbles, remove the pneumatic pump from the container, push it multiple times on the floor, press the follower plate down, and operate the pressurised grease control gun. Furthermore, connect the compressed air. For stiff grease, use grease with not more than consistency grade NLGI 2. Insert the pump centrally to reduce the friction loss.
