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 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.

1 inch pp pneumatic diaphragm 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 inch diaphragm pump for paints & solvents.

The LL316 stainless steel pneumatic diaphragm pump offers a wide range of fluids from low to high viscosity and low to high corrosion. The stainless steel LL316 air operated diaphragm pump is suitable for conveying high viscosity honey in medicine and chemical industry and food industry. 

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. 

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.

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.

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.
