Model GSO, classified as a single-stage end-top centrifugal pump, was developed as a core product for various industrial fields in the global market. This product ensures more versatility and reliability by complying with international standards including ISO 5199 and ISO 2858. Furthermore, for covering a wide range of services, it is designed to use a uniquely shaped impeller (reverse-open impeller. the impeller’s hub plate is open) to handle not only clean applications but also process liquids containing light slurries. High efficiency, high quality, and enhanced usability have been achieved using fluid, structural, vibration analysis and experiments as development and design techniques.
