Flange

The valve ball materials are Teflon, Santoprene, EPDM, ect. It has a very low friction coefficient, excellent self-lubrication, good corrosion resistance, dimensional stability, and no deformation.

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.

1.5inch air operated diaphragm pump in mining industry: tunnel sewage, drainage, coal slime and stone slurry, cement slurry, mortar grouting, explosive slurry, lubricating oil, 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. 

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. 

The valve ball materials are Teflon, Santoprene, EPDM, ect. It has a very low friction coefficient, excellent self-lubrication, good corrosion resistance, dimensional stability, and no deformation. valve seat: The valve seat materials are Teflon, Santoprene, Buna-n, ect.

2 inch stainless steel pneumatic diaphragm pump is a chemical resistant diaphragm pump, and it is Suitable for medium and high viscosity fluid, is a liquid transfer air diaphragm pump.

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.
