The Series QBY air operated diaphragm pump is a new kind of transportation machine and a newest pump in China. It is using compressed air as a power source, and can pumped all kinds of corrosive liquid entirety. It works as well as those imported from Germany WLLDENPVMPS or USA MARIOWPUMPS, It has been adopted by thousands of domestic company for petroleum, chemical, electronics, ceramics, and textile.

The diaphragm pumps are widely used in water supply and drainage type of fluid, serous transmission, highly toxic, flammable, volatile liquid delivery, jam, oil and special plastic suction media delivery. The pump has self –sucking function without the electricity motive. It is no leaking and jamming. The air pressure: 0.1 Mpa～0.7Mpa. the temperature: -4℃～400℃ the sticky liquid (sticky degree below10000centipoise)

 

No need of lead water, has the merit of self-sucking pump, dive pump, shield pump, slurry pump.

It can be immersed in media work, no need for oil lubrication of the pump, even the idling of pumps, it has no impact. The outlet pressure and flux has reached no step adjustment through the valve opening adjustment. This pump can be used in transporting the easy floating liquid and hard floating liquid. organic  the standard suction distance: 7m Outlet Pressure 50m exit pressure ≥6kgf/c㎡.
