Types of multistage centrifugal pumps are divided into: Self-balancing multi-stage pump, single suction multi-stage centrifugal pump, double inlet multi-stage centrifugal pump, double suction horizontal multi-stage centrifugal pump and multi-stage double-suction pump, each of which has its own unique advantages, in this article, multi-stage centrifugal pump manufacturer Changsha Zoomlian Pump industry will focus on introducing the product advantages of multi-stage double-suction pump designed and produced by our company, after reading this article, You will have a deeper understanding of the multi-stage medium-open double suction pump.
1. High efficiency and energy conservation: The utilization of an efficient hydraulic model and an optimized flow channel enables the hydraulic efficiency of the multistage open pump to reach the optimum. The double inlet parallel flow channel structure eliminates balanced water leakage, sealing water leakage, and volume loss caused by the axial force balancing device. Additionally, no additional axial force balancing device such as a balance drum is needed, and there is no axial channeling during operation.
2. Large flow capacity: The double suction pump is equivalent to two single suction impellers of the same diameter operating simultaneously. Under the same impeller diameter, the flow rate can be doubled. This structural design makes the double suction pump widely applicable in industrial scenarios that demand large flow rates.
3. Facilitated maintenance: The pump shell is horizontally opened, enabling easy inspection and maintenance. The inlet and outlet of the double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet water pipes. We should not underestimate this advantage. During long-term operation, convenient maintenance will be a very distinct advantage.
4. Symmetrical structure and smooth operation: The impeller structure of the double suction pump is symmetrical, eliminating axial force, and ensuring stable operation. The optimal design of the double suction impeller minimizes the axial force and features excellent hydraulic performance of the blade profile and has been optimized.
5. Wide application range: Suitable for industrial and urban water supply and drainage, agricultural drainage and irrigation, as well as water and other liquids with physical and chemical properties similar to water. The temperature range of the transported liquid is wide, ranging from -20°C to 80°C. Widely utilized in water conservancy projects, especially in high-altitude areas of water diversion projects, where combinations of single-suction multistage centrifugal pumps and multistage double-suction pumps are often employed to achieve the objective of large flow and high lift water transportation.
6. Excellent anti-cavitation performance: The horizontal open double suction volute and impeller structure enable the multistage open pump to have significantly superior anti-cavitation performance compared to the single suction multistage centrifugal pump, indicating that the pump can adapt to higher suction, and the installation conditions have greater tolerance.
