Air Operated Diaphragm Pump Valve Ball

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. 

AOK50 PVDF self priming AODD pump is easy to use, reliable and simple to operate. When the 2inch PVDF air powered diaphragm pump accident will automatically stop, with good self-protection performance. When the AOK50 pneumatic diaphragm pump everything back to normal, and can automatically start running.

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.

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.

AOE100 air operated double diaphragm pump with sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.

Flange connection is a detachable connection, It is the part that connects a pipe to a fitting or device. It is usually used for connecting pipe ends or for equipment inlet and outlet.

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.
