QBK pneumatic diaphragm pump

QBK pneumatic diaphragm pump is the third generation of pneumatic diaphragm pump developed by our company, with long service life, will not stop and other advantages, it can pump the flowing liquid, but also can transport some difficult to flow the medium, with self-priming pump, submersible pump, shield pump, mud pump and impurity pump and other conveying machinery many advantages.


1, do not need irrigation water. Suction up to 5m. Lift up to 70m. Outlet pressure ≥6bar.
2, flow spacious, through the performance is good. The maximum particle diameter allowed through is 10mm. When pumping mud and impurities, little wear to the pump;
3. The head and flow can be adjusted stepless by the opening of the air valve (the air pressure is adjusted between 1 and 7bar) :
4. The pump has no rotating parts, no shaft seal, and the diaphragm completely separates the pumping medium from the moving parts of the pump and the workpiece medium, and the conveyed medium will not leak outwards. Therefore, when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and harm personal safety;
5, no electricity. Safe and reliable in flammable and explosive places;
6, can be immersed in the medium to work;
