AOK50 high flow flap valve Air Operated Diaphragm Pump liquid flow is spacious and good through performance, It is a Large particle passing capacity diaphragm pump, It has a strong capacity for the passage of large solid particles. allowing passage of solid particles with a maximum particle diameter of 40 mm. This aluminum alloy flap valve air operated diaphragm pump is very popular in chemical industry. 

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.

AOK0610- Stainless steel pneumatic diaphragm pump using imported raw materials, keep the good performance of the pump. Our 1/4 inch mini pneumatic diaphragm pump can not only transport water, It can also be used as a chemical liquid conveying pneumatic pump.

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. 

Food grade self priming AODD pumps are ideally suited for applications that require a robust, plug-and-play, and easy-to-maintain stainless steel two diaphragm air pump.

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.

AOK15 Polypropylene air diaphragm pump is a kind of air operated double diaphragm pump for sulphuric acid with good chemical stability, has strong acid and alkali corrosion resistance. 

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.
