I. Overview of QBK Third-Generation Pneumatic Diaphragm Pump Products:

The QBK third-generation pneumatic diaphragm pump is the third generation model developed by our company, featuring a long service life and no stopping, etc. It can both pump flowing liquids and transport some non-liquid media, incorporating many advantages of self-priming pumps, submersible pumps,屏蔽 pumps, sludge pumps, and杂质 pumps.

Advantages of QBK Third Generation Pneumatic Diaphragm Pump

1. The QBK third-generation pneumatic diaphragm pump does not require priming water. It has a suction lift of up to 5m, a discharge head of 70m, and an outlet pressure of ≥6bar.

2. Ample flow, excellent performance; allows particles up to 10mm in diameter to pass through. Minimal wear on the pump during slurry and impurities pumping.

3. Head and flow can be infinitely adjusted through the valve opening (pressure regulation between 1-7 bar):

4. The pump has no rotating parts or shaft seals. The diaphragm completely isolates the pumped medium from the pump's moving parts and workpiece medium, ensuring no leakage of the conveyed medium. Therefore, when pumping toxic, volatile, or corrosive media, it does not cause environmental pollution or pose a threat to personal safety.

5. Non-electric; safe and reliable for use in flammable and explosive areas.

6. Can operate submerged in the medium:

7. The QBK third-generation pneumatic diaphragm pump is user-friendly, reliable in operation, and can be started and stopped simply by opening and closing the gas valve. Even if it runs for an extended period without medium due to an accident or suddenly shuts down, the pump will not be damaged. In the event of overload, the pump will automatically shut down, featuring self-protection capabilities. Once the load returns to normal, it can automatically restart and operate.

8. Simple structure with minimal wear parts, this pump boasts a straightforward design, easy installation, and maintenance. The medium being pumped does not come into contact with moving parts like the valve control and connecting rods, unlike other types of pumps where performance gradually diminishes due to wear on components such as rotors, pistons, gears, and blades.

9. Capable of transporting more viscous liquids (viscosity under 10,000 centistokes):

10. The QBK third-generation pneumatic diaphragm pump requires no oil lubrication, even when running empty, which has no impact on the pump at all. This is the pump's major feature.
