The QBK pneumatic diaphragm pump is the third-generation pneumatic diaphragm pump developed by our company, featuring a long service life and no stalling. It can pump flowing liquids as well as transport some difficult-to-flow media, offering many advantages of conveying machinery such as self-priming pumps, submersible pumps, slurry pumps, and impurity pumps.

Product Features

1. No need to prime with water.

2. Wide flow path with excellent passing performance, allowing the passage of particles up to 10mm in diameter. When pumping slurry or impurities, wear on the pump is minimal;

3. Head and flow can be steplessly adjusted by opening the air valve;

4. Since the diaphragm completely separates the conveyed medium from the moving parts and working medium of the pump, the conveyed medium will not leak outward. Therefore, when pumping toxic, volatile, or corrosive media, it will not cause environmental pollution or endanger personal safety;

5. No electricity required. Safe and reliable for use in flammable and explosive environments;

6. Can operate submerged in the medium:

7. Easy to use and reliable in operation. Starting and stopping only require simply opening and closing the gas valve. Even if the pump runs without medium for an extended period due to unexpected circumstances or suddenly stops, it will not be damaged. Once overloaded, the pump will automatically stop, featuring self-protection. When the load returns to normal, it can automatically restart and operate;

8. Simple structure with few vulnerable parts. The pump has a simple structure, is easy to install and maintain, and the medium conveyed does not come into contact with moving parts such as the air distribution valve and connecting rod. Unlike other types of pumps, whose performance gradually declines due to wear of rotors, pistons, gears, blades, and other components;

9. Can transport relatively viscous liquids (viscosity below 10,000 centipoise);

10. This pump does not require oil lubrication. Even if it runs dry, it has no impact on the pump, which is a major feature.
