2Inch Mine Pneumatic Double Diaphragm Pump AOE50-370/0.1

1.5inch air operated diaphragm pump in mining industry: tunnel sewage, drainage, coal slime and stone slurry, cement slurry, mortar grouting, explosive slurry, lubricating oil, etc.

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.

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. 

1.5 inch plastic air operated double diaphragm pump AODD pump is also known as corrosion resistant engineering plastic AODD pump, Its flow pump body part is made of polypropylene, is not rust, no pollution, strong corrosion resistance of the 1.5 inch diaphragm pump for paints & solvents, acid liquid.

The valve ball materials are Teflon, Santoprene, EPDM, ect. It has a very low friction coefficient, excellent self-lubrication, good corrosion resistance, dimensional stability, and no deformation. valve seat: The valve seat materials are Teflon, Santoprene, Buna-n, ect.

The role of connecting rod is to connect the piston and the crankshaft, so that the reciprocating linear motion of the piston into the rotary motion of the crank, in order to output power.

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.

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.
