Diaphragm Rod (Shaft)

The O-ring is also called the sealing ring, It is a kind of rubber sealing ring with circular cross section, which is the most common mechanical design for sealing.

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.

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.

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.

AOK40 PVDF pneumatic diaphragm pump powered by compressed air, when the 1.5 Inch Compressor Air Diaphragm Pump exhaust is an expansion endothermic process. And the AOK40 PVDF self priming pneumatic duplex diaphragm pump working temperature is reduced, no harmful gas discharge. 

Quick Connector is a joint that can connect or disconnect pipes without tools.  The operation is simple, time saving and manpower saving when disconnecting and connecting with quick connector.

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

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.
