Flange

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.

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.

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. 

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.

Stainless steel pneumatic diaphragm pump is also called food sanitary pneumatic diaphragm pump. AOK0610-LL316 stainless steel pneumatic diaphragm pump is often used for occasions with high health requirements and strong corrosion performance of media. For example, in a Milk factory, The pneumatic diaphragm pump is used for milk transportation.

1/4 inch mini polypropylene pneumatic diaphragm pump has six advantages, such as reliable quality, long service life, low noise, small vibration, high head, never crash and fine workmanship.

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.
