Flange

1/2 Inch Aluminum Membrane Pump ,which is driven by air. It is a kind of positive displacement pumps which volume changes caused by compressing diaphragms in both side.

High pressure diaphragm pump are high efficiency positive displacement reciprocating duplex diaphragm water pump that can be used in multiple fluid-transfer applications, It is a high efficiency diaphragm pump.

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 AOK high performance air operated diaphragm pump can be used according to different liquid medium different materials, in order to meet the needs of different users.

Food grade self priming AODD pumps are ideally suited for applications that require a robust, plug-and-play, and easy-to-maintain stainless steel two diaphragm air pump.

1.5 inch Polypropylene air operated duplex diaphragm pump polypropylene material density is relatively small, is also one of the lightest plastic diaphragm pump material. Therefore, the 1.5 inch pp pneumatic diaphragm pump is very light and convenient and has strong mobility.

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. 

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.
