3/8 inch air operated double diaphragm pump can pump a variety of toxic, flammable, volatile liquid, slurry, BioFloc, high viscosity fluids, corrosive liquids and paint. It also can be used for cleaning sediment contaminant in shaft, tunnels and sewers.
Features
- Pneumatic dual diaphragm pump can transport high temperature media up to 150 ℃.
- Adopt pilot operated type air valve to eliminate the AODD pump downtime and extend its life span.
- It is designed with multiport to help you install it easily.
- Air powered diaphragm pump can be used as a movable-type material transfer pump because it has such advantages as small in size, easy moving, no need base, small occupied area and easy installation.
- It can be externally connected to an electromagnetic valve for remote control. And the reversing valve requires no lubrication.

Tips: Why choose ATO air operated double diaphragm pump?
ATO 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.
Low price air operated double diaphragm pump for sale, 3/8 inch fluid inlet and outlet, 1/4 in. air inlet, 5 GPM max. flow, working pressure up to 100 PSI, selectable body material of cast steel, aluminum alloy, non-metallic and stainless steel. AODD pump can be used for water purifier and high viscosity fluids.
