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. 

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.

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.

AOK15 Polypropylene air diaphragm pump is a kind of air operated double diaphragm pump for sulphuric acid with good chemical stability, has strong acid and alkali corrosion resistance. 

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

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 plastic self priming diaphragm pump has a very strong self-priming function. The use of 2 inch pp air diaphragm pump without rotating parts, dry and wet absorption can be achieved.

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.
