Pneumatic diaphragm pumps cause pulse and hydraulic vibration due to their own reciprocating motion impact, and may cause damage to the whole pumping system. Pulsating dampers eliminate almost all hydraulic vibration and improve overall performance and stability of industrial fluid flow processes and chemical transport processes.

Plastic 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.

1 inch pp pneumatic diaphragm pump is also known as corrosion resistant engineering plastic AODD pump, Its flow pump body part is made of polypropylene, is not rust, no pollution, strong corrosion resistance of the 1 inch diaphragm pump for paints & solvents.

Aluminum mining air operated double diaphragm pump low density, high strength. It can be used for transporting chemically unstable fluids.

High pressure double membrane pump are ideally suited for applications that require a robust, plug-and-play, and easy-to-maintain metal two diaphragm air pump.

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. 

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.
