    Product information

    What is a Multi-Stage Pump?

    • Definition: A centrifugal pump with multiple impellers mounted on a common shaft, each stage adding incremental pressure to the fluid.
    • Key Principle: The total head = sum of heads from each stage.
    • Typical Stages: 2–10 (special designs up to 30).
    • Pressure Range: 150 psi – 5,000 psi (1–35 MPa).

    Types of Multi-Stage Pumps

    Type Characteristics Typical Applications
    Horizontal Split Multistage Centrifugal Radial flow, double-suction first stage, easy maintenance Municipal water, industrial plants
    Vertical Turbine Multistage Compact footprint, high efficiency, suited for deep wells Water supply, irrigation
    Barrel Casing Multistage High-pressure, robust casing, API 610 compliant Oil & gas pipelines, boiler feed
    Ring Section Multistage Modular design, economical, compact HVAC, fire-fighting systems
    Axial/Mixed Flow Multistage High flow, lower head per stage Cooling water circulation, desalination

     Technical Specifications

    • Head per Stage: 30–250 ft (9–76 m).
    • Total Head: Up to 2,000+ m for boiler feed pumps.
    • Efficiency: 60–85%.
    • Motor Power: Up to ~20,000 hp (15 MW).
    • Speed Range: 1,500–3,600 rpm.
    • Materials: Cast iron, stainless steel, duplex alloys.
    • Temperature Range: –20 °C to 250 °C.

     Applications

    • Water Supply & Treatment: High-rise buildings, municipal water distribution.
    • Boiler Feed: Power plants requiring high-pressure feedwater.
    • Oil & Gas Pipelines: Transporting fluids over long distances.
    • Chemical Processing: Handling corrosive or high-pressure fluids.
    • Fire-Fighting Systems: Reliable high-pressure water delivery.
