Overview: The GS series of single-stage double-suction centrifugal pumps represent the third generation of high-efficiency, energy-saving double-suction pumps developed by our company through innovative efforts, based on the extensive adoption of advanced technologies from similar products both at home and abroad. It features a wide range of models, excellent hydraulic performance, and a novel design; it boasts high efficiency and reliability, as well as the notable advantages of a low net positive suction head and low maintenance requirements. The design, manufacturing, and quality of this series of products comply with the G BIT5657 standard \"Technical Requirements for Centrifugal Pumps – Class III\", while their efficiency parameters meet the requirements of the G8197B2 standard \"Energy Efficiency Limits and Evaluation Criteria for Freshwater Centrifugal Pumps\". Application areas: This series of products is used for transporting clean water or other liquids with physical and chemical properties similar to those of clean water. Utilizing corrosion-resistant or wear-resistant materials, they can convey industrial wastewater, seawater, or turbid water containing a small amount of particles. It is widely used in the water supply and drainage systems or cooling circulating water systems of industrial enterprises such as those in the steel, petrochemical, thermal power generation, and mining sectors. It can also be applied to urban tap water systems, circulating water in heating systems, irrigation for farmland drainage, as well as various water conservancy projects. Performance range: Flow rate: 135–38,000 m3/h; Head: 12–225 m; Diameter: 150–1800 mm. Structural features: Schematic diagram of the structure
