Air Operated Diaphragm Pump Valve Ball

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.

3Inch Air membrane pump with high capacity, metal material body good using for mining industry. The air pump has the good self priming function with dry priming and wet priming.

1/2 inch mini polypropylene pneumatic diaphragm pump has six advantages, such as reliable quality, long service life, low noise, small vibration, high head, never crash and fine workmanship.

1.5 inch Polypropylene air operated duplex diaphragm pump polypropylene material density is relatively small, is also one of the lightest plastic diaphragm pump material. Therefore, the 1.5 inch pp pneumatic diaphragm pump is very light and convenient and has strong mobility.

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. 

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

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.

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.
