It is engineered for environments requiring complete submersion and continuous-duty operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic design utilizes a shrouded two-channel impeller that enables a 76.2 mm solids passage. Performance characteristics reach a maximum total head of 23.5 m and a maximum flow rate of 10000 L\/Min. This configuration is specifically designed for 250mm discharge bore connections.\u003c\/p\u003e\u003cp\u003eA 6-pole dry-type induction motor provides steady hydraulic delivery at a synchronous speed of 1000 min?¹. This 22 kW three-phase unit operates on a 415v supply with a rated current of 47 Amps at 50Hz. Electrical activation is facilitated by an integrated Star-Delta starting method.\u003c\/p\u003e\u003cp\u003eStandard supply is a free-standing unit with a cast iron base stand. A guide rail fitting version is available under model code TO250BZ622H, 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\u003eShrouded two-channel impeller with a maximum solids passage of 76.2 mm.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seals with Silicon Carbide faces isolated in an oil chamber where both faces run in a clean environment.\u003c\/li\u003e\n\u003cli\u003eTsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal and continues supplying oil even if lubricant levels are low.\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\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 prevents moisture migration 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.
