1/4 Inch Portable Mini Air Operated Double Diaphragm Pump does not need to divert water, both can pump flowing liquid, and can transport some not easy to flow medium. 

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. 

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.

Pneumatic coupling refers to air filter and pressure reducing valve. The pressure reducing valve can stabilize the pressure of the gas source, so that the gas source is in a constant state, which can reduce the damage to the valve or actuator and other hardware when the air pressure of the gas source changes abruptly. The filter is used to clean the air source. It can filter the water in the compressed air and avoid the water entering the device with the gas.   

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.

Stainless steel aodd pump can be used as mobile material delivery pump. 25mm stainless steel aodd pump is not only small in size, but also easy to move, no need for foundation, small footprint, simple and economical installation.

Metal diaphragm pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc.

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.
