Section 1: 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 handle both flowing liquids and some non-liquid media, incorporating many advantages of self-priming pumps, submersible pumps,屏蔽 pumps, sludge pumps, and impurity pumps.

QBK Third-Generation Pneumatic Diaphragm Pump Product Advantages

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. Spacious flow, excellent performance in passage. Allows passage of particles up to 10mm in diameter. Minimally wears down the pump when pumping sludge and impurities.

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

4. This pump has no rotating parts or shaft seals. The diaphragm separates the pumped medium from the pump's moving parts and work medium, ensuring no leakage of the medium. Therefore, when pumping toxic, volatile, or corrosive substances, it prevents environmental pollution and hazards to personal safety.

5. Non-electric operation. 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 easily started and stopped by simply opening and closing the gas valve. Even if it runs without medium for an extended period due to unforeseen circumstances 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 will automatically restart and resume operation.

8. The pump features a simple structure with minimal wearing parts, making it easy to install and maintain. The medium being pumped does not come into contact with moving parts like the valve actuator or rods, unlike other pump types where wear on components such as rotors, pistons, gears, or blades gradually reduces performance.

9. Capable of transporting liquids with high viscosity (viscosity below 10,000 centipoise).

10. The QBK third-generation pneumatic diaphragm pump does not require oil lubrication, and it operates smoothly even when running empty. This feature is the pump's most significant characteristic.
