Tips: Why choose CCHN air operated double diaphragm pump?

CCHN air operated double diaphragm pump has many advantages, which can be applied to various fields, such as sewage disposal, petrochemical industry, food, construction, pharmaceutical, furniture and paint industry. Miniature pneumatic dual diaphragm pump also can be used in the household, such as pumping color paint if you need to paint your house. Here are reasons why you choose our 3/8 inch AODD pumps.

The air powered diaphragm pump requires compressed air to work, which will not overheat. Exhaust is the process of heat absorption, the working temperature is reduced with no harmful gas discharge.
AODD pump is no need electric power, so it will not generate and electric spark and static spark.
Due to AOD pump is the positive displacement type works and the fluid inlet is a ball valve, it is not easy to be blocked.
This pneumatic double diaphragm pump is designed with self-suction, and the fluid flow is adjustable.
It can transport fluid in an extremely wide range, from low to high viscosity and from corrosive to viscous.
Our pump will be productive all the time, it will not decrease work efficiency as it wears out.
