    Configured for municipal sewage and industrial wastewater management, this 37 kW model is suitable for continuous-duty operation in liquids with temperatures ranging from 0 to 40°C. The unit remains completely submerged during service, handling raw sewage and effluents.

    Performance specifications reach a maximum total head of 27.5 m and a maximum flow rate of 15000 L/Min at 50Hz. The 37 kW motor draws a rated current of 72 Amps.

    The 4-pole dry-type induction motor in this unit achieves a synchronous speed of 1500 min?¹ for its operating cycles. Motor activation is managed by a Star-Delta starting method, providing a controlled electrical application on a 415v three-phase supply. This configuration includes a shrouded two-channel impeller with an 80 mm solids passage for handling wastewater containing suspended solids.

    Free-standing installation is the standard configuration for this unit, provided with a cast iron base stand for stable placement. A guide rail fitting version is available under model code TO250BZ437, allowing the pump to be connected to or disconnected from the discharge piping by lowering or hoisting the unit.

    FEATURES

    • Tsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal and continues supplying oil even if lubricant falls below the rated volume.
    • Pressure relief port protects the mechanical seal against excessive pressure and draws abrasive particles away from the seal faces.
    • Shrouded two-channel impeller with a maximum solids passage of 80 mm.
    • Double-face Silicon Carbide mechanical seals isolated in an oil chamber providing a clean lubricating environment.
    • Miniature thermal protectors embedded in each motor winding which signal the control panel to shut off power if excessive heat builds up.
    • Watertight cable entry with an anti-wicking block preventing water incursion due to capillary action through damaged power leads.
    • Permanently lubricated deep-groove double-shielded C3 ball bearings support the rotating shaft.
