It operates effectively in deep sumps where the pump is subject to complete submersion in liquid temperatures between 0 and 40°C. The design focuses on providing reliable continuous-duty service in large-scale wastewater treatment plants.\u003c\/p\u003e\u003cp\u003eThe performance curve for this 37 kW model indicates a maximum total head of 20 m and a maximum flow rate of 18000 L\/Min. Drawing a rated current of 79 Amps on a 415V three-phase supply, the motor provides the hydraulic output for its 350 mm discharge bore. Activation is managed by an integrated Star-Delta starting method.\u003c\/p\u003e\u003cp\u003eOperating at a synchronous speed of 1000 min?¹, the 6-pole dry-type induction motor provides power to the hydraulic assembly. A shrouded two-channel impeller for solid-handling design is utilized, enabling a 90 mm solids passage size at 50Hz. This design ensures functional fluid movement through the large-bore discharge piping.\u003c\/p\u003e\u003cp\u003eMechanical hardware consists of a Gray Cast Iron JIS FC250 pump casing and 420 stainless steel shafting for long-term submerged stability. Standard supply is a free-standing unit with a cast iron stand. A guide rail fitting version is available under model code TO350BZ637H, which identifies the variant suitable for remote hoisting and inspection without entering the pit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eShrouded two-channel impeller for solid-handling design, dynamically balanced.\u003c\/li\u003e\n\u003cli\u003eMaximum solids passage of 90 mm for moving raw sewage and suspended matters.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seal located in oil chamber where both upper and lower seal faces run in a clean environment.\u003c\/li\u003e\n\u003cli\u003eTsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal and continues to supply the oil to the upper seal faces even if lubricant falls below the rated volume.\u003c\/li\u003e\n\u003cli\u003eIntegrated pressure relief port protects the mechanical seal from excessive pressure and draws abrasive grit away.\u003c\/li\u003e\n\u003cli\u003eMiniature thermal protectors embedded in motor windings signal the control panel to shut off power if excessive heat builds up.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable entry block prevents water incursion due to capillary action should the power cable be damaged.\u003c\/li\u003e\n\u003cli\u003eDegree of protection rated at IP68 for complete submersion in heavy-duty high-head industrial applications.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50946659352823,"sku":"350BZ637H","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-350bz637h-cast-iron-high-head-submersible-sewage-pump-municipal-sewage-two-channel.png?v=1784259447","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-350bz637h-cast-iron-high-head-submersible-sewage-pump-municipal-sewage-two-channel","provider":"Foundation Pumps","version":"1.0","type":"link"}
