2inch polypropylene air operated duplex diaphragm pump can be used directly as a submersible pump, it uses air as the power source, and does not have the leakage and other security risks. This diaphragm pump has lower cost than submersible pump which is caused by the maintenance of motor.

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.

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. 

AOK15 Polypropylene air diaphragm pump is a kind of air operated double diaphragm pump for sulphuric acid with good chemical stability, has strong acid and alkali corrosion resistance. 

2 inch stainless steel pneumatic diaphragm pump is a chemical resistant diaphragm pump, and it is Suitable for medium and high viscosity fluid, is a liquid transfer air diaphragm pump.

Diaphragm has Teflon (PTFE), Viton, Buna-n, Neoprene, Santoprene, EPDM, etc. materials. That is imported material, the diaphragm stress of air operated diaphragm pump is reduced to the minimum, and the service life is extended.

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.

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.
