The API 610-11th standard is strictly followed by the JHDK/JHDK-D series, which consists of multi-stage, axially split centrifugal pumps supported at both ends. Lower NPSH characteristics are achieved in the JHDK-D model through the implementation of a double-suction first-stage impeller. ANSI or ISO standards dictate the sizing of the discharge and suction flanges. A sealing chamber designed to ISO21049/API682 standards is incorporated, and all connections for buffer, flushing, cooling, heating, and emergency cooling pipelines comply with API schemes. Broad industrial adoption includes environmental protection engineering, refined oil and boiler feedwater transport, metallurgy, mining, petroleum pipelines, petrochemicals, and oil refining. Additionally, the chemical industry utilizes these units as high-pressure hydraulic energy recovery turbines, while the fertilizer and synthetic ammonia sectors employ them as rich liquid and lean solution pumps.
