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.

Aluminum mining air operated double diaphragm pump low density, high strength. It can be used for transporting chemically unstable fluids.

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.

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.

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.

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.

The role of connecting rod is to connect the piston and the crankshaft, so that the reciprocating linear motion of the piston into the rotary motion of the crank, in order to output power.

Diaphragm Rod (Shaft)  from #321 stainless steel, the connecting rod has good corrosion resistance, abrasion resistance, and self-lubricating performance. Particularly grinded, the surface has lower friction coefficient.
