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.

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.

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

3Inch Air membrane pump with high capacity, metal material body good using for mining industry. The air pump has the good self priming function with dry priming and wet priming.

AODD pumps are high efficiency positive displacement reciprocating duplex diaphragm water pump that can be used in multiple fluid-transfer applications, It is a high efficiency diaphragm pump. 

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.

PVDF Air operated double diaphragm pump with strong chemical resistance, crush resistance, abrasion resistance, good corrosion resistance for acid, alkali and variety of organic solvents.

AOE100 air operated double diaphragm pump with sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.
