Quick Connector

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.

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. 

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.

AOK50 High Viscosity Medium Air Operated Reciprocating Self Priming Diaphragm Pump without oil lubrication, even idling on the pump without any impact.

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.

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.

AOE aluminum air driven pump with simple structure, less wearing parts, At the same time, the slurry double diaphragm pump is a kind of corrosion resistant pneumatic diaphragm pump, And it can transport viscosity within the range of 10000 centipoises of liquid.

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.
