Reciprocating aluminum alloy air operated double diaphragm pump has the advantages of large suction range, adjustable flow, absolute fire and explosion protection. It is an excellent aluminum alloy diaphragm pump.

PVDF Air operated double diaphragm pump with strong chemical resistance, crush resistance, abrasion resistance, good corrosion resistance for acid, alkali and variety of organic solvents.

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.

 Stainless steel pneumatic diaphragm pump for chemical in the transportation of hazardous and corrosive liquids, the liquid can be completely separated from the outside world. It is a kind of corrosion resistant chemical 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.

AOK aluminum air driven diaphragm pump 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 centipores of liquid.

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

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.
