Self-priming single-stage double-suction centrifugal pump: fast start-up, efficient drainage and irrigation

Self-priming single-stage double-suction centrifugal pump Product Overview
Welcome to the self-priming single-stage, double-suction centrifugal pump recommended by Yixuan Platform—a highly efficient fluid transfer solution designed for complex applications such as modern agricultural irrigation, urban drainage, industrial water use, and emergency flood control. This product combines rapid self-priming, high-flow delivery, and stable operation, making it a reliable and powerful partner for various drainage and irrigation scenarios.

Self-priming single-stage double-suction centrifugal pump Core Advantages

✅ Quick Start, No Priming Required

Utilizing advanced self-priming technology, the pump automatically primes within 60 seconds after startup, eliminating the need for pre-priming. This significantly reduces operating time and improves efficiency. It is particularly suitable for applications with frequent starts and stops or installation locations above the liquid level.

✅ Double-suction impeller design for high flow and efficiency

The innovative single-stage, double-suction structure draws liquid simultaneously from both sides of the impeller, effectively balancing axial forces, reducing vibration and wear, and achieving higher flow rates with lower energy consumption. Compared to traditional single-suction pumps, this pump delivers over 30% higher flow rates and smoother operation.

✅ Widely Applicable to a Wide Range of Media
Can transport clear water or liquids with similar physical and chemical properties. Suitable for a variety of applications, including farmland irrigation, fish pond pumping, municipal drainage, construction site drainage, and factory circulating water systems, it offers strong adaptability.

✅ Durable, Reliable, and Easy to Maintain
The pump body is constructed of high-strength cast iron or stainless steel, resisting corrosion and wear. The mechanical seal design prevents leaks and offers a long service life. The modular structure allows for easy assembly and disassembly, making daily maintenance simple and efficient.
