 QBK is coosai’s new developed series of AODD pump which is also the third generation, it has the virtue of long service life and nonstop operation, not only it 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.

1. It’s unnecessary to pour the drawing water, the suction lift reaches 5 m height, the delivery lift reaches 70 m length and the export pressure≥6bar.

2. Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. The damage is very less to the pump while exhausting the slurry and impurity.

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. This pump has no rotary parts and no bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. The conveyed medium can’t be leaked outside. Thus it will not cause 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.
