1 inch pp pneumatic diaphragm pump is also known as corrosion resistant engineering plastic AODD pump, Its flow pump body part is made of polypropylene, is not rust, no pollution, strong corrosion resistance of the 1 inch diaphragm pump for paints & solvents.

Our AOK50 PP high flow flap valve pneumatic diaphragm pump can be called the Large solid particle flap valve diaphragm pump, it can pass through the larger solid particles. the use of the AOK50 PP flap valve waste water diaphragm pump even in bad working conditions, the impurities of sewage or complex liquid medium, is not easy to plug.

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.

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

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. 

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.

AOK06/10 PVDF air operated diaphragm pump is a kind of 1/4 Inch standard pneumatic diaphragm pump using a new piezoelectric polymer material. The PVDF vacuum pump diaphragm is not only small density light weight, but also good flexibility, and has good chemical stability.

1/2 Inch Aluminum Membrane Pump ,which is driven by air. It is a kind of positive displacement pumps which volume changes caused by compressing diaphragms in both side.
