    Suitable for heavy-duty wastewater handling and municipal applications, this high-head unit manages raw sewage and industrial effluents. It operates effectively in deep processing tanks where the pump is subject to complete submersion and continuous-duty service. The design is intended for liquids between 0 and 40°C containing substantial suspended matters.

    The performance curve indicates a maximum total head of 31 m and a maximum flow rate of 15000 L/Min at 50Hz. This 45 kW model operates on a 415V three-phase supply with a rated current of 87 Amps. Electrical control of the motor is managed by a Star-Delta starting configuration.

    The unit utilizes a 4-pole dry-type induction motor reaching a synchronous speed of 1500 min?¹. An integrated water jacket surrounds the motor frame where a portion of the pumped liquid cools the motor during operation. The hydraulic design utilizes a shrouded two-channel impeller for solid-handling design with an 80 mm solids passage.

    Structural construction consists of a Gray Cast Iron JIS FC250 pump body and 420 stainless steel motor shaft. Standard supply for this model is free-standing. A guide rail fitting version is available under model code TO300BZ445H, which allows easy maintenance and inspection without the requirement of entering the sump.

    FEATURES

    • Integrated water jacket around the motor frame where a portion of the pumped liquid flows through the jacket for cooling.
    • Shrouded two-channel impeller for solid-handling design, dynamically balanced.
    • Maximum solids passage of 80 mm for wastewater carrying solid matters.
    • Double-face mechanical seal located in oil chamber where both upper and lower seal faces run in a clean environment.
    • Tsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal even if lubricant levels are low.
    • Upper permanently lubricated deep-groove double-shielded C3 ball bearing for motor shaft stability.
    • Lower duplex angular contact ball bearing mounted back-to-back for mechanical stability during high-torque processing.
    • Watertight cable entry with an anti-wicking block protects internal motor components from water incursion via damaged power leads.
