The QBK pneumatic diaphragm pump is a third-generation model powered by compressed air, featuring multiple advantages and a wide range of application scenarios.

Features and Advantages

No priming required: The QBK pneumatic diaphragm pump does not require priming, with a suction lift of up to 5 meters, a discharge head of up to 70 meters, and an outlet pressure of ≥6bar.

Excellent performance: The pump's flow is spacious, allowing for large particle diameters up to 10mm, suitable for pumping sludge, impurities, etc., with minimal wear on the pump.

Continuous Adjustment: Head and flow can be continuously adjusted through the valve opening, with pressure adjustment ranging from 1 to 7 bar.

Safety and Reliability: This pump features no rotating parts and no shaft seal, ensuring complete isolation of the medium from the pump's moving components. It prevents any outward leakage and is suitable for toxic, volatile, or corrosive media, thereby avoiding environmental pollution and potential harm to personal safety.

Wide Application Range: No power required, suitable for flammable and explosive areas, can operate submerged in media, easy to use, reliable in operation, and will not be damaged even after long-term operation without media or sudden shutdown.

Simple Structure: The pump has a straightforward design, making installation and maintenance easy, and it is unaffected even when running empty.

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 particulate matter in food.

Environmental Industry: Used for treating wastewater and sludge, etc.

Other Industries: Such as the ceramic industry, textile industry, etc., suitable for various applications requiring high reliability and safety.
