    Recommended for high-volume drainage in mining facilities and construction sites where high-head dewatering is required. The spiral side discharge casing is designed for permanent or semi-permanent installations using fixed piping systems for site water management. This design provides the capacity for rapid water displacement over significant elevations to maintain site progress.

    Driven by a 37 kW 415v motor, the pump achieves a maximum flow of up to 8580 L/Min and a maximum head of up to 42 m through a 200 mm discharge. It handles drainage water containing up to 15% dry matter across a wide pH range. The 4-pole motor delivers the hydraulic torque required for consistent discharge in large-scale civil engineering projects.

    The hydraulic system utilizes a spiral side discharge casing that optimizes flow and maintains movement of solids up to 25 mm. This arrangement minimizes internal friction and prevents material accumulation within the housing, which is necessary for efficiency during long dewatering cycles. The streamlined path reduces localized wear from abrasive site debris.

    Durability is supported by a motor cooling jacket that maintains safe temperatures during shallow-sump or exposed operation. Seal pressure relief ports divert high internal pump pressure from the mechanical seal faces to prevent premature failure. The pump is constructed with a cast iron body and utilizes a Star-Delta starting method and Class F insulation.

    FEATURES

    • High-capacity hydraulic design delivers flow up to 8580 L/Min for site dewatering and water control.
    • Spiral side discharge casing facilitates the passage of 25 mm solids while reducing internal turbulence.
    • Seal pressure relief ports protect the mechanical seal from excessive high-pressure internal stress.
    • Integrated water jacket allows for motor cooling when the liquid level is below the motor housing.
    • Heavy-duty 4-pole motor provides the torque necessary for continuous high-volume site drainage.
    • Cast iron body and Class F insulation support reliable operation in rough construction environments.
    • Star-Delta starting method ensures controlled electrical startup for the 37 kW power system.
    • Side discharge outlet is compatible with large-bore 200 mm piping and guide rail fitting systems.
