The configuration is intended for liquids within a 0 to 40°C temperature range, managing water carrying solid matters.\u003c\/p\u003e\u003cp\u003eDriven by a three-phase motor operating on a 415v supply, the unit reaches a maximum flow rate of 15000 L\/Min and a maximum total head of 31.0 m. It draws a rated current of 87 Amps at 50Hz.\u003c\/p\u003e\u003cp\u003eThe dry-type induction motor features a 4-pole design and maintains a synchronous speed of 1500 min?¹. Electrical activation is facilitated by an integrated Star-Delta starting method to manage the power application. The hydraulic design utilizes a shrouded two-channel impeller enabling an 80 mm solids passage.\u003c\/p\u003e\u003cp\u003eStandard installation for this 45 kW model is a free-standing configuration with a cast iron stand. A guide rail fitting version is available under model code TO250BZ445, allowing the pump to be connected to or disconnected from the discharge piping by lowering or hoisting the unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePermanently lubricated deep-groove double-shielded C3 ball bearings supporting the vertical rotating assembly for continuous duty.\u003c\/li\u003e\n\u003cli\u003eMiniature thermal protectors embedded in each motor winding which signal the control panel to shut off power if excessive heat builds up.\u003c\/li\u003e\n\u003cli\u003eWatertight cable entry with an anti-wicking block protects the motor from water incursion due to capillary action.\u003c\/li\u003e\n\u003cli\u003ePressure relief port protects the mechanical seal against excessive pressure by drawing abrasive particles away from the faces.\u003c\/li\u003e\n\u003cli\u003eShrouded two-channel impeller with a maximum solids passage of 80 mm.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seals with Silicon Carbide faces isolated in an oil chamber.\u003c\/li\u003e\n\u003cli\u003eTsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal even if lubricant falls below the rated volume.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
