1. Summarize 
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. It is installed in a variety of special occasions, for pumping all types of medium which can't be sucked by other pump. The pump body can be made of aluminum alloys, cast iron or stainless steel according to customers' demand. 

2. Usage 
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 degree the sticky liquid (sticky degree below10000centipoise) 

3. Characteristic 
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 

4. Main Features 
A. Our Pneumatic diaphragm pump is different from most of other Chinese pump for well mannfactured, well seal and good dry suction. 
B. Four bolts connection with very round ball, well seal and good dry suction. The actual dry suction can reach to 4~7m. 
C. High roundness valve ball for use the ball mill machine. 
D. Three section manifold, Flexible installation and even can simultaneously convey two different liquids. 
E. Longer diaphragm life. Diaphragm material from Dopont, Exxon. 
F. Pilot type air valve, low maintenance, low air consumption, so the using cost is low. 
G. Wetted body: PPH, PVDF, SS304, SS316, Aluminum etc. 
H. Diaphragm: PTFE, Hytrel, Santoprene, Viton etc.
