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. 

80mm plastic irrigation pneumatic duplex diaphragm pump pumping liquid medium is not only the flow of liquid, but also can transport some not easy to flow of liquid medium, 3 inch Polypropylene air driven diaphragm pump has self-priming pump, mud pump, impurities pump and other comprehensive advantages.

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.

The LL316 stainless steel pneumatic diaphragm pump offers a wide range of fluids from low to high viscosity and low to high corrosion. The stainless steel LL316 air operated diaphragm pump is suitable for conveying high viscosity honey in medicine and chemical industry and food industry. 

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.

Aluminum alloy double diaphragm pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc. It is an excellent aluminum alloy diaphragm pump.

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

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.
