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.

Flexible Hose: Explosion-proof flexible connecting pipe is suitable for combustible dust environment, It has the advantages of fire resistance, corrosion resistance, water resistance, aging resistance, good flexibility, firm structure and reliable operation. Chemical hose: Can be widely used to transport corrosive chemical liquids and gases, excellent chemical resistance. The special construction process makes it cost-effective, light, soft, easy to operate and durable.

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 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.

Diaphragm materials are Teflon (PTFE), Viton, Buna-n, Neoprene, Santoprene, EPDM, ect. Made of imported material, the diaphragm stress of air operated diaphragm pump is reduced to the minimum, and the service life is extended.

AOK25 PVDF pneumatic diaphragm pump is considered to be the most chemically stable material, AOK25 high quality PVDF pneumatic pump for chemical has good chemical stability. This chemical air powered double diaphragm pump can not only be used for a variety of corrosive liquids and high viscosity liquids, but also can be used to transport flammable and explosive liquids.

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.
