SZL-Type Vertical Single-Stage Double-Suction Center-Opening Centrifugal Pump
The SZL vertical single-stage double-suction split-case centrifugal pump, with its unique vertical design and high-efficiency performance, has become the preferred equipment for conveying clean water and water-like media in industries, municipal applications, agriculture, and other sectors. Specifically designed to handle clean water free of solid particles—or liquids whose physical and chemical properties closely resemble those of pure water—the pump is ideally suited for medium temperatures ranging from 0°C to 80°C. Its vertical installation feature is particularly advantageous in scenarios where pump room space is limited, significantly reducing the footprint of the pump room and lowering infrastructure costs. Widely used in critical areas such as industrial water supply and drainage, urban water distribution and treatment, and agricultural irrigation and drainage systems, this pump provides a stable and reliable fluid-handling solution for users—including small rural pumping stations and municipal water plants.
ISG Series Single-Stage Vertical Pipeline Pump
The ISG-type vertical single-stage pipeline centrifugal pump is jointly developed by engineers from Changsha Zoomlion Pump Industry Technology and leading domestic pump experts, who selected an outstanding domestic hydraulic model and adopted the performance parameters of the IS-type centrifugal pump. Built upon the foundation of conventional vertical pumps, this innovative design achieves a clever integration of components. Additionally, based on the specific application—such as varying operating temperatures or media types—this series of pumps has been further refined into specialized models tailored for hot water, high-temperature, corrosive chemical, and oil applications.
This product line boasts numerous advantages, including high efficiency, energy savings, low noise levels, and reliable performance, making it fully compliant with the standards set forth in the national Ministry of Machinery’s JB/T53058-93 specification. Moreover, the pumps are designed and manufactured according to the international ISO 2858 standard.
In 1993, these pumps successfully passed the unified quality inspection conducted by China’s Ministry of Machine Industry for pipeline pump products.
They are ideally suited for conveying clean water free of solid particles, as well as other liquids whose physical and chemical properties closely resemble those of water. (The ISG-type pump is also known by various names, including pipeline centrifugal pump, single-stage centrifugal pump, clear water centrifugal pipeline pump, vertical centrifugal pump, booster pump, hot-water pump, and circulation pump.)
