Air Operated Diaphragm Pump Diaphragm

3Inch Air membrane pump with high capacity, metal material body good using for mining industry. The air pump has the good self priming function with dry priming and wet priming.

The pump body installed with muffler, the delivery head and flow can pass the pneumatic valve open to realize the step less adjustment,  Effectively reduce air duct noise.

AOK40 PVDF pneumatic diaphragm pump powered by compressed air, when the 1.5 Inch Compressor Air Diaphragm Pump exhaust is an expansion endothermic process. And the AOK40 PVDF self priming pneumatic duplex diaphragm pump working temperature is reduced, no harmful gas discharge. 

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. 

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

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 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.

AOK80 3inch high volume reciprocating stainless steel pneumatic diaphragm pump in the work of the fluidstirring minimum, no heat occurs, the machine will not overheat.
