Applications

Applications of Air Operated Double Diaphragm Pump

Tips: Why does the pressure of the air operated diaphragm pump drop suddenly?

Caused by insufficient fuel supply. It is recommended to repair the fuel valve in time.
The material has not reached a certain amount when the material is being fed, or there is an oil leakage phenomenon, it is necessary to check the actual situation of the material in time to control the oil leakage.
The pneumatic diaphragm pump has no action, or the action is very slow. This situation may occur because the air valve is stuck, and the air valve is worn. If the air valve is stuck, clean it in time. You can use a certain cleaning agent. If the air valve is worn, replace it with a new one.
