The air diaphragm pump has the function of self priming without rotating parts. It can achieve dry priming and wet priming, which self -priming height is 5m and 8m respectively.

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.

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.

1/2 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.

1.5inch air operated diaphragm pump in mining industry: tunnel sewage, drainage, coal slime and stone slurry, cement slurry, mortar grouting, explosive slurry, lubricating oil, etc.

1.5 inch plastic air operated double diaphragm pump AODD 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 1.5 inch diaphragm pump for paints & solvents, acid liquid.

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.

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.
