The QBK pneumatic diaphragm pump is a third-generation model powered by compressed air, offering numerous advantages and a wide range of applications.
Features and Advantages
No priming required: The QBK diaphragm pump does not require priming, with a suction lift of up to 5 meters and a discharge head of up to 70 meters, and an outlet pressure of ≥6 bar.
Excellent performance: The pump features ample flow, allowing passage of large particle diameters up to 10mm, suitable for pumping sludge, impurities, etc., with minimal wear on the pump.
Stepless adjustment: Head and flow can be infinitely adjusted via the opening of the gas valve, with a pressure adjustment range of 1-7bar.
Safe & Reliable: The pump has no rotating parts and no shaft seal, completely isolating the medium from the pump's moving parts, ensuring no outward leakage. Suitable for toxic, volatile, or corrosive media, it poses no risk of environmental pollution or harm to personal safety.
Wide Application Range: No power required, suitable for flammable and explosive environments, can be submerged in media for operation, easy to use, reliable performance, and will not be damaged even after long-term operation without media or sudden shutdown.
Simple Structure: The pump features a straightforward design, making installation and maintenance easy, and it is unaffected by operation without fluid.
Application Scenario
The QBK pneumatic diaphragm pump is widely used in various applications involving corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic substances. Specific applications include:
Chemical Industry: Used for pumping various corrosive liquids and impurities.
Food Industry: Used for conveying thick liquids and granular materials in food.
Environmental Industry: Used for treating wastewater and sludge, etc.
Other Industries: Such as the ceramics industry, textile industry, etc., suitable for various applications requiring high reliability and safety.
