Double Inlet & Outlet Air Operated Diaphragm Pump AOE15 25

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

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. 

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.

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.

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. 

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.

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.

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.
