    Frequently Asked Questions
    Q What is the key difference between S and SH series double-suction centrifugal pumps?
    The S series is a standard double-suction centrifugal pump suitable for general large-flow applications, while the SH series is an enhanced variant engineered for higher-temperature and higher-pressure environments, such as supercritical power plants and refinery cooling systems, with upgraded bearing housings rated to 150℃.
    Q How does the double-suction design eliminate axial thrust?
    The axial-split double-flow impeller draws fluid simultaneously from both sides, creating equal and opposing hydraulic forces that cancel each other out. This eliminates net axial thrust, reducing bearing load by up to 60% and extending bearing L10 life beyond 50,000 hours.
    Q What is the maximum fluid temperature the S/SH pump can handle?
    The S/SH series double-suction centrifugal pumps are rated for fluid temperatures up to 135℃. The bearing housing is independently rated to 150℃, and a seal chamber cooling jacket is included to maintain seal integrity at elevated operating temperatures.
    Q Can these pumps handle seawater or mildly contaminated fluids?
    Yes. The S800 model has been validated in oil tanker ballast applications with seawater containing up to 35,000ppm chloride (Cl⁻) concentration, achieving 5 years of leak-free operation. The pumps can also handle fluids with solid particles up to 1mm at concentrations below 3%, making them suitable for raw water pre-treatment.
    Q What bore sizes and flow capacities are available?
    The S/SH series covers a wide bore range from DN100 to DN1200mm, supporting flow rates up to 20,000m³/h for large-scale plant cooling applications. Maximum head reaches 135m, making them suitable for deep well direct supply and high-lift industrial systems.
    Q What after-sales support and warranty is provided?
    Every S/SH series pump includes hydraulic profile optimization support and a 3-year warranty covering all pressure-bearing components. With 35 branches and offices nationwide and exports to over 20 countries including Russia, Canada, Australia, India, and Africa, our global service network ensures responsive technical and maintenance support.
