Split-type Double-suction Chemical Pump

The double-suction pump is a single-stage, horizontally split, centrifugal pump designed for open-water applications. It delivers high flow rates, elevated head capabilities, and exceptional hydraulic efficiency-contributing to significant energy savings. This pump series operates within a head range of 10–150 m and a flow rate range of 112–6,250 m³/h. It is engineered for the conveyance of clean water and other liquids with physical and chemical properties comparable to water, at temperatures not exceeding 80 °C.
Typical applications include municipal water supply and wastewater management, district heating systems, thermal and nuclear power generation facilities, centralized HVAC systems, agricultural irrigation and drainage, flood control infrastructure, and comprehensive water resources development projects.

Key Features of Double-Suction Pumps

1.High-Capacity Performance​

The dual-inlet configuration enables the pump to deliver flow rates substantially exceeding those of comparable single-suction models. By integrating two opposing inlets, it effectively combines the output of two impellers, providing superior volumetric performance. The typically larger impeller diameter further enhances its ability to achieve higher heads, making it ideal for high-volume applications.

2.Reliable and Efficient Operation​

Advanced hydraulic design ensures smooth internal flow paths, reducing turbulence and energy loss. The pump casing and impeller are precision-cast to minimize surface resistance, which improves overall efficiency and reduces the risk of cavitation. Balanced axial forces contribute to stable, low-vibration operation and extended service life.

3.Easy Maintenance and Installation​

Featuring a horizontally split casing, the pump allows quick access to internal components for inspection or servicing without major disassembly. The suction and discharge flanges are usually aligned horizontally and positioned below the shaft centerline, simplifying piping connections and reducing installation time and complexity.

4.Versatile Application Adaptability​

Standard versions are designed for clean water and similar low-viscosity fluids operating below 80°C. Customized options are also available, including models built with corrosion-resistant alloys or engineered for elevated temperatures, ensuring suitability across a wide range of industrial, municipal, and commercial uses.
