AOK25 PVDF pneumatic diaphragm pump is considered to be the most chemically stable material, AOK25 high quality PVDF pneumatic pump for chemical has good chemical stability. This chemical air powered double diaphragm pump can not only be used for a variety of corrosive liquids and high viscosity liquids, but also can be used to transport flammable and explosive liquids.

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. 

Our AOK50 PP high flow flap valve pneumatic diaphragm pump can be called the Large solid particle flap valve diaphragm pump, it can pass through the larger solid particles. the use of the AOK50 PP flap valve waste water diaphragm pump even in bad working conditions, the impurities of sewage or complex liquid medium, is not easy to plug.

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.

1/2 Inch Aluminum Membrane Pump ,which is driven by air. It is a kind of positive displacement pumps which volume changes caused by compressing diaphragms in both side.

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.

1/4 Inch Portable Mini Air Operated Double Diaphragm Pump does not need to divert water, both can pump flowing liquid, and can transport some not easy to flow medium. 

2inch polypropylene air operated duplex diaphragm pump can be used directly as a submersible pump, it uses air as the power source, and does not have the leakage and other security risks. This diaphragm pump has lower cost than submersible pump which is caused by the maintenance of motor.
