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.

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.

Removable Muffler: 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. 

AODD pumps 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. 

AOK50 High Viscosity Medium Air Operated Reciprocating Self Priming Diaphragm Pump without oil lubrication, even idling on the pump without any impact.

Small size self priming SS304 stainless steel pneumatic diaphragm pump low density, high strength, good plasticity. It can be used for transporting chemically unstable fluids.

Our AOK50 PP high flow flap valve pneumatic diaphragm pump can be called the Large solid particle flap valve diaphragm pump, it can pass through the larger solid particles. the use of the AOK50 PP flap valve waste water diaphragm pump even in bad working conditions, the impurities of sewage or complex liquid medium, is not easy to plug.

2 inch AOE 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.
