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.

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.

Air operated diaphragm pump is a kind of 1/2 Inch and 1inch 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.

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

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.

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.

Small size self priming SS304 stainless steel pneumatic diaphragm pump low density, high strength, good plasticity. It can be used for transporting chemically unstable fluids.

Plastic 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.
