Product description:
        QBY air operated diaphragm pumps not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits the merits of self-pumping pump, diving pump, shield pump, slurry pump and impurity pump etc.
     
Feature:
 1. It's unnecessary to pour the drawing water, the suction lift reaches 5 m height, the delivery lift reaches 70 mlength and the export pressure≥6bar. 2. Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. 3. The delivery lift and flow can pass the pneumatic valve open to realize the step less adjustment(the pneumatic pressure adjustment is between 1-7bar). 4.  The pump will notcause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium. 5. No electricity. It's safe and reliable while using in the flammable and explore places. 6. It can be soaked in medium. 7. Simple structure and less wearing parts.  8. It can transmit the adhesive liquid (the viscosity is below 10000 centipoises). 9. This pump needn't the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.  Product Size
