Product Description: Air Operated Double Diaphragm Pump

The Air Operated Double Diaphragm Pump (QBY Series) manufactured by our company represents an advanced fluid handling solution designed to meet a wide range of industrial needs. Powered entirely by compressed air, this pump eliminates the risk of electric spark generation, making it ideal for use in explosive or flammable environments. With its rugged construction, chemical resistance, and efficient operation, the QBY pump is a versatile tool for the safe and reliable transfer of challenging fluids.

This pump operates using two flexible diaphragms driven alternately by compressed air. As one diaphragm is pushed by the air, it displaces the fluid through the discharge valve, while the other diaphragm is drawn back, creating suction and pulling more fluid into the opposite chamber. This reciprocating action ensures a smooth, consistent flow of liquids, even in demanding working conditions.

One of the key strengths of the QBY Air Operated Double Diaphragm Pump is its ability to handle a diverse range of liquids. Whether you are transferring aggressive chemicals, abrasive slurries, viscous resins, or liquids laden with solids, this pump provides outstanding performance. It is especially well-suited for applications involving high-viscosity materials that traditional centrifugal or gear pumps struggle with. The QBY pump is built with durable materials that resist chemical corrosion, mechanical wear, and thermal degradation, ensuring long-term reliability in the harshest of environments.

Another major advantage of this pump is its dry-running capability. Unlike many other types of pumps, the QBY can run dry without causing damage, which is particularly beneficial in operations where flow interruptions may occur. Additionally, the pump’s self-priming feature allows it to draw fluid from below the level of the pump, making it choice for emptying tanks, drums, and sumps.

The QBY pump is designed for ease of maintenance. With a compact and modular design, it can be quickly disassembled for inspection or repairs. The simplicity of its mechanism also reduces the number of parts prone to wear and failure, thus downtime and maintenance costs.

Versatility is at the core of the QBY design. It can be used across a wide array of industries including chemical processing, pharmaceuticals, food and beverage, mining, petroleum, water treatment, and textiles. In food-grade applications, specific models are constructed from stainless steel and feature food-safe diaphragms, ensuring compliance with hygiene regulations. In chemical plants, models made with PTFE and other inert materials can withstand the corrosive effects of acids, alkalis, and solvents.

Environmental safety is another area where this pump excels. Since it uses air instead of electricity, it is inherently safer in hazardous locations. The air-powered mechanism also allows for variable speed and flow control simply by adjusting the air pressure or flow rate, offering precise control without the need for complex electronic systems.

Furthermore, the QBY Air Operated Double Diaphragm Pump is energy-efficient and environmentally friendly. It consumes compressed air only during active strokes, and some models are equipped with energy-saving air distribution systems that further reduce operational costs. Its leak-free construction and gentle pumping action also help preserve the integrity of sensitive fluids and reduce the risk of contamination or spills.

With a wide range of sizes and materials available—including aluminum alloy, cast iron, stainless steel, polypropylene, and fluoroplastics—the QBY pump can be tailored to meet the specific needs of virtually any fluid handling task. Each pump undergoes rigorous quality control to ensure consistent performance and durability.

In summary, the QBY Air Operated Double Diaphragm Pump offers solution for industries requiring a robust, adaptable, and efficient method of transferring liquids. With its ability to handle corrosive, viscous, abrasive, and hazardous fluids, it provides a safer and more effective alternative to conventional pumping technologies. Whether you are looking for a pump to support continuous operation in a manufacturing line or require reliable performance in intermittent service applications, the QBY series is a trusted choice for professionals across a wide range of sectors.
