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.

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.

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. 

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. 

2 inch plastic self priming diaphragm pump has a very strong self-priming function. The use of 2 inch pp air diaphragm pump without rotating parts, dry and wet absorption can be achieved.

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.

Aluminum alloy double diaphragm pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc. It is an excellent aluminum alloy diaphragm pump.

Reciprocating aluminum alloy air operated double diaphragm pump has the advantages of large suction range, adjustable flow, absolute fire and explosion protection. It is an excellent aluminum alloy diaphragm pump.
