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

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.

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.

80mm plastic irrigation pneumatic duplex diaphragm pump pumping liquid medium is not only the flow of liquid, but also can transport some not easy to flow of liquid medium, 3 inch Polypropylene air driven diaphragm pump has self-priming pump, mud pump, impurities pump and other comprehensive advantages.

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.

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

AOK15 Polypropylene air diaphragm pump is a kind of air operated double diaphragm pump for sulphuric acid with good chemical stability, has strong acid and alkali corrosion resistance. 

PVDF Air operated double diaphragm pump with strong chemical resistance, crush resistance, abrasion resistance, good corrosion resistance for acid, alkali and variety of organic solvents.
