QBK pneumatic diaphragm pump specifications

QBK pneumatic diaphragm pump is the third generation of pneumatic diaphragm pump , with long service life, without pause and so on. It can not only pump the flowing liquid, but also transport some difficult to flow medium, with self-priming pump , submersible pump , shield pump , Mud pump and impurity pump and many other advantages of conveyor machinery.

1, without irrigation water. Suction up to 5m, lift up to 70m, the outlet pressure ≥ 6bar.

2, flow-spacious, through the good performance, allowing the maximum particle diameter up to 10mm. Pumping mud, impurities, the pump wear little;

3, head, flow through the valve opening to achieve stepless adjustment (barometric pressure adjustment between 1-7 bar);

4, the pump without rotating parts, there is no shaft seal, diaphragm and other pumping media and pump moving parts, working media completely separated, the media will not be delivered to the outside leakage. Therefore, pumping toxic, volatile or corrosive media, will not cause environmental pollution and endanger personal safety;

5, no electricity, safe and reliable in flammable and explosive places;

6, can be immersed in the media work;

7, easy to use, reliable, open stop just open and close the gas valve . Even if due to unexpected conditions and prolonged non-media operation or sudden shutdown pump will not be damaged, once the overload, the pump will automatically shut down, with self-protection performance, when the load back to normal, but also automatically start running;

8, simple structure, less wearing parts, the pump structure is simple, easy installation, maintenance, pump delivery medium will not come into contact with valve, connecting rod and other moving parts, unlike other types of pumps due to rotor, piston , gear , Leaves and other parts of the wear and tear so that performance gradually declined;

9, can transport a more viscous liquid (viscosity of 10,000 centipoise below);

10, the pump without oil lubrication, even idle, the pump has no effect, this is the most significant feature of QBK pneumatic diaphragm pump.
