Flange

The O-ring is also called the sealing ring, It is a kind of rubber sealing ring with circular cross section, which is the most common mechanical design for sealing.

AOK80 PVDF self priming pneumatic duplex diaphragm pump can always remain efficient, not because of wear and tear and reduce efficiency. AOK80 PVDF air diaphragm pump can make 100% of the energy utilization, When the pneumatic diaphragm pump outlet is closed, the 3 inch PVDF air operated duplex diaphragm chemical pump will automatically stop. There is no equipment movement, wear, overload, heating phenomenon.

Removable Muffler: The pump body installed with muffler, the delivery head and flow can pass the pneumatic valve open to realize the step less adjustment. Effectively reduce air duct noise. 

Food grade self priming AODD pumps are ideally suited for applications that require a robust, plug-and-play, and easy-to-maintain stainless steel two diaphragm air pump.

Mini polypropylene pneumatic pump is a pump which driven by air. The air pump can be widely used in NAOH, sulfuric acid etc. It has the self priming function and can run dry.

Small size self priming SS304 stainless steel pneumatic diaphragm pump low density, high strength, good plasticity. It can be used for transporting chemically unstable fluids.

AOK40 PVDF pneumatic diaphragm pump powered by compressed air, when the 1.5 Inch Compressor Air Diaphragm Pump exhaust is an expansion endothermic process. And the AOK40 PVDF self priming pneumatic duplex diaphragm pump working temperature is reduced, no harmful gas discharge. 

Aluminum mining air operated double diaphragm pump low density, high strength. It can be used for transporting chemically unstable fluids.
