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.

1Inch booster Air operated membrane pump is often used for sewage, slurry, gasoline, and diesel oil etc. With high pressure and high capacity, has the self priming function with wet priming 8m.

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. 

AOK06/10 PVDF air operated diaphragm pump is a kind of 1/4 Inch standard pneumatic diaphragm pump using a new piezoelectric polymer material. The PVDF vacuum pump diaphragm is not only small density light weight, but also good flexibility, and has good chemical stability.

AOK50 High Viscosity Medium Air Operated Reciprocating Self Priming Diaphragm Pump without oil lubrication, even idling on the pump without any impact.

AOK50 high flow flap valve Air Operated Diaphragm Pump liquid flow is spacious and good through performance, It is a Large particle passing capacity diaphragm pump, It has a strong capacity for the passage of large solid particles. allowing passage of solid particles with a maximum particle diameter of 40 mm. This aluminum alloy flap valve air operated diaphragm pump is very popular in chemical industry. 

The air diaphragm pump has the function of self priming without rotating parts. It can achieve dry priming and wet priming, which self -priming height is 5m and 8m respectively.

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.
