It is designed for environments requiring complete submersion and continuous-duty service in collection sumps. The configuration manages raw sewage and water carrying solid matters.\u003c\/p\u003e\u003cp\u003eA maximum flow rate of 14000 L\/Min and a maximum total head of 23.0 m define the hydraulic output of this submersible unit. Operating on a 415v three-phase supply, the 30 kW motor draws a rated current of 59 Amps at 50Hz.\u003c\/p\u003e\u003cp\u003eThe motor is a 4-pole dry-type induction motor operating at a synchronous speed of 1500 min?¹. Activation is controlled through a Star-Delta starting configuration to manage the electrical load during the initial power application. The pump features a shrouded two-channel impeller which enables an 80 mm solids passage for handling wastewater containing suspended solids.\u003c\/p\u003e\u003cp\u003eStructural hardware consists of a Gray Cast Iron JIS FC250 pump casing and a 420 stainless steel shaft. This model is supplied as a free-standing unit with a cast iron stand. A guide rail fitting version is available under model code TO250BZ430, 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\u003eMiniature thermal protectors embedded in each 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 housing from water incursion due to capillary action.\u003c\/li\u003e\n\u003cli\u003ePermanently lubricated deep-groove double-shielded C3 ball bearings supporting the 420 stainless steel shaft for continuous duty.\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 volume falls below the rated level.\u003c\/li\u003e\n\u003cli\u003eIntegrated pressure relief port designed to protect the mechanical seal by drawing abrasive particles away from the faces.\u003c\/li\u003e\n\u003cli\u003eSecondary lip seal used as a dust seal to protect the primary sealing system from fine sand and abrasive particles.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
