Air Operated Diaphragm Pump Diaphragm

1 inch pp pneumatic diaphragm pump is also known as corrosion resistant engineering plastic AODD pump, Its flow pump body part is made of polypropylene, is not rust, no pollution, strong corrosion resistance of the 1 inch diaphragm pump for paints & solvents.

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.

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. 

The valve seat materials are Teflon, Santoprene, Buna-n, etc.

The valve ball materials are Teflon, Santoprene, EPDM, ect. It has a very low friction coefficient, excellent self-lubrication, good corrosion resistance, dimensional stability, and no deformation.

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.

High pressure double membrane pump are ideally suited for applications that require a robust, plug-and-play, and easy-to-maintain metal two diaphragm air pump.

Diaphragm Rod (Shaft)  from #321 stainless steel, the connecting rod has good corrosion resistance, abrasion resistance, and self-lubricating performance. Particularly grinded, the surface has lower friction coefficient.
