It is designed for deep-well sumps where the pump is subject to complete submersion while handling raw sewage carrying significant suspended solids. The configuration manages liquids from 0 to 40°C requiring continuous-duty service.\u003c\/p\u003e\u003cp\u003eHydraulic performance reaches a maximum total head of 35 m and a maximum flow rate of 18000 L\/Min at 50Hz. Drawing a rated current of 144 Amps on a 415V supply, the 75 kW three-phase motor provides the hydraulic output for 350 mm discharge bores. Motor activation is managed by an integrated Star-Delta starting configuration during activation.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a 4-pole dry-type induction motor at a synchronous speed of 1500 min?¹. A portion of the pumped liquid flows through a water jacket around the motor frame to cool the motor during operation. The hydraulic design features a shrouded two-channel impeller for solid-handling design enabling a 90 mm solids passage.\u003c\/p\u003e\u003cp\u003eStructural hardware consists of a Gray Cast Iron JIS FC250 pump casing and 420 stainless steel motor shaft. Standard supply is a free-standing unit with an integrated base stand. A guide rail fitting version is available under model code TO350BZ475H, allowing easy maintenance and inspection without entering the collection sump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegrated water jacket around the motor frame where a portion of the pumped liquid cools the motor during continuous duty.\u003c\/li\u003e\n\u003cli\u003eShrouded two-channel impeller for solid-handling design, dynamically balanced.\u003c\/li\u003e\n\u003cli\u003e90 mm solids passage for moving suspended solid matters.\u003c\/li\u003e\n\u003cli\u003eDouble-face Silicon Carbide mechanical seals 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 to supply the oil to the upper seal faces even if lubricant levels are low.\u003c\/li\u003e\n\u003cli\u003eUpper permanently lubricated deep-groove double-shielded C3 ball bearing for motor shaft stability.\u003c\/li\u003e\n\u003cli\u003eLower duplex angular contact ball bearing mounted back-to-back to manage high mechanical loads.\u003c\/li\u003e\n\u003cli\u003eWatertight cable entry featuring a molded anti-wicking block to stop water incursion due to capillary action.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50946659451127,"sku":"350BZ475H","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-350bz475h-cast-iron-water-jacket-submersible-sewage-pump-wastewater-two-channel.png?v=1784259452","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-350bz475h-cast-iron-water-jacket-submersible-sewage-pump-wastewater-two-channel","provider":"Foundation Pumps","version":"1.0","type":"link"}
