The design focus is on providing continuous-duty operation in liquids from 0 to 40°C that carry substantial suspended solid matter.\u003c\/p\u003e\u003cp\u003ePerformance specifications reach a maximum total head of 57.5 m and a maximum flow rate of 9500 L\/Min at 50Hz. This model operates at 75 kW on a 415v three-phase supply, drawing a rated current of 144 Amps.\u003c\/p\u003e\u003cp\u003eA water jacket is equipped around the motor frame, allowing a portion of the pumped liquid to flow through the water jacket to cool the motor during continuous operation. The pump utilizes a 4-pole dry-type induction motor that reaches a synchronous speed of 1500 min?¹. Electrical activation is managed by a Star-Delta starting method.\u003c\/p\u003e\u003cp\u003eMechanical construction utilizes Gray Cast Iron JIS FC250 for the pump casing and 420 stainless steel for the motor shaft. Standard supply is a free-standing unit with a cast iron stand. A guide rail fitting version is available under model code TO250BZ475H, 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\u003eWater jacket around the motor frame where a portion of the pumped liquid flows through the jacket to cool the motor.\u003c\/li\u003e\n\u003cli\u003eDuplex angular contact ball bearing mounted back-to-back at the lower position.\u003c\/li\u003e\n\u003cli\u003eUpper permanently lubricated deep-groove double-shielded C3 ball bearing.\u003c\/li\u003e\n\u003cli\u003eShrouded two-channel impeller with a maximum solids passage of 76.2 mm.\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\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 prevents moisture migration through damaged power leads.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
