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.

 Stainless steel pneumatic diaphragm pump for chemical in the transportation of hazardous and corrosive liquids, the liquid can be completely separated from the outside world. It is a kind of corrosion resistant chemical diaphragm pump.

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. 

1.5 inch Polypropylene air operated duplex diaphragm pump polypropylene material density is relatively small, is also one of the lightest plastic diaphragm pump material. Therefore, the 1.5 inch pp pneumatic diaphragm pump is very light and convenient and has strong mobility.

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. 

80mm plastic irrigation pneumatic duplex diaphragm pump pumping liquid medium is not only the flow of liquid, but also can transport some not easy to flow of liquid medium, 3 inch Polypropylene air driven diaphragm pump has self-priming pump, mud pump, impurities pump and other comprehensive advantages.

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.

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.
