    Frequently Asked Questions
    Q What is the key advantage of a double-suction centrifugal pump over a single-suction model?
    Double-suction pumps feature axial-split double-flow impellers that completely eliminate axial thrust, reducing bearing load by up to 60% and extending bearing L10 life beyond 50,000 hours. They also deliver 40% higher flow capacity compared to single-suction models of the same size.
    Q What is the maximum bore size and temperature rating of the S/SH series pumps?
    The S/SH series supports bore sizes ranging from DN100 up to DN1200mm, with a maximum fluid temperature tolerance of 135℃. The bearing housing itself is rated for up to 150℃, making it suitable for demanding thermal system applications.
    Q Can the S/SH series handle seawater or corrosive fluids?
    Yes. The S800 model has been validated in oil tanker ballast applications handling seawater with chloride concentrations up to 35,000 ppm Cl⁻, achieving five years of leak-free operation. Material and seal configurations can be specified for corrosive environments.
    Q What solid particle sizes and concentrations can these pumps handle?
    The S/SH series can handle solid particles up to 1mm in size at concentrations below 3%, making them well-suited for raw water pre-treatment and similar applications involving lightly contaminated fluids.
    Q What warranty and after-sales support is provided?
    All S/SH series pumps come with a 3-year warranty on pressure parts. The company also provides hydraulic profile optimization services and has a network of 35 branches and offices to ensure responsive technical and service support across major regions.
    Q In which industries are S/SH series double-suction pumps most commonly used?
    These pumps are widely deployed in power generation (including supercritical power plants), marine and offshore (oil tanker ballast systems), petrochemical refinery cooling, municipal water supply, and large-scale industrial plant cooling systems requiring flows up to 20,000 m³/h.
