The unit remains completely submerged during service, handling raw sewage and effluents.\u003c\/p\u003e\u003cp\u003ePerformance 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eFree-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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal and continues supplying oil even if lubricant falls below the rated volume.\u003c\/li\u003e\n\u003cli\u003ePressure relief port protects the mechanical seal against excessive pressure and draws abrasive particles away from the seal 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 Silicon Carbide mechanical seals isolated in an oil chamber providing a clean lubricating environment.\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 preventing water incursion due to capillary action through damaged power leads.\u003c\/li\u003e\n\u003cli\u003ePermanently lubricated deep-groove double-shielded C3 ball bearings support the rotating shaft.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
