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

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.

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.

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.

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.

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. 

Stainless steel aodd pump can be used as mobile material delivery pump. 25mm stainless steel aodd pump is not only small in size, but also easy to move, no need for foundation, small footprint, simple and economical installation.

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.
