2inch polypropylene air operated duplex diaphragm pump can be used directly as a submersible pump, it uses air as the power source, and does not have the leakage and other security risks. This diaphragm pump has lower cost than submersible pump which is caused by the maintenance of motor.

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.

AOE100 air operated double diaphragm pump with sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.

AOE aluminum air driven pump with 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 centipoises of liquid.

High pressure booster air powered membrane pump is a kind of excellent performance, has more corrosion resistance, more wear resistance, more high temperature resistance and other high-quality pneumatic diaphragm pump.

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 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.

The valve seat materials are Teflon, Santoprene, Buna-n, etc.

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.

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.

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.
