Product overview

QBK pneumatic diaphragm pump is the third generation of pneumatic diaphragm pump. It has the advantages of long service life and no pause. It can not only pump flowing liquid, but also transport some difficult flowing medium. It has many advantages of self-priming pump, submersible pump, canned motor pump, mud pump and impurity pump.

1. There is no need to inject water. The suction head is as high as 5m. The lift is 70m. The outlet pressure is more than 6kg / cm2.

2. The flow is spacious and the passing performance is good. It is allowed to pass large particles with a diameter of 10 mm. When pumping mud and impurities, the pump has little wear; the head and flow can be adjusted steplessly through the valve opening (the air pressure is adjusted between 1-7kg / cm2)

3. The pump has no rotating parts, no shaft seal, diaphragm, etc. the pumped medium is completely separated from the moving parts and workpiece medium of the pump, and the transported medium will not leak out. Therefore, when pumping toxic, easy to play or corrosive media, it will not cause environmental pollution and endanger personal safety;

4. No electricity is needed. It is safe and reliable to use in inflammable and explosive places;

5. It can work in the medium:

6. It is easy to use and work reliably. It only needs to simply open and close the gas valve, even if it is long due to accidents

Once the pump is overloaded, the pump will stop automatically, which has self-protection performance. When the load returns to normal, it can start running automatically;

The pump has simple structure and few vulnerable parts. The pump is simple in structure, easy to install and maintain. The medium transported by the pump will not contact the moving parts such as valve and connecting rod. Unlike other types of pumps, the performance gradually declines due to the wear of rotors, pistons, gears, blades and other components

It can transport viscous liquid (viscosity below 10000 centipoise)

The pump does not need oil lubrication, even if it is idling, it has no effect on the pump, which is a major feature of the pump.
