It operates in environments requiring complete submersion and continuous-duty operation in deep processing sumps. The unit manages liquids between 0 and 40°C carrying substantial solid matters.\u003c\/p\u003e\u003cp\u003eOperating characteristics include a maximum total head of 34.5 m and a maximum flow rate of 15000 L\/Min at 50Hz. Drawing a rated current of 110 Amps on a 415V three-phase supply, the 55 kW motor provides the hydraulic output for 300 mm discharge bore systems. Motor activation is managed by the Star-Delta starting method.\u003c\/p\u003e\u003cp\u003eA portion of the pumped liquid flows through a water jacket around the motor frame to cool the motor during operation. The unit features a 4-pole dry-type induction motor with a synchronous speed of 1500 min?¹ and a shrouded two-channel impeller for solid-handling design. This hydraulic assembly facilitates a maximum solids passage of 90 mm.\u003c\/p\u003e\u003cp\u003eConstruction features a Gray Cast Iron JIS FC250 pump casing and 420 stainless steel motor shaft. Standard supply is a free-standing unit with a cast iron stand. A guide rail fitting version is available under model code TO300BZ455H, which connects the pump to and from the piping easily by lowering or hoisting the pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEquipped with a water jacket around the motor frame where a portion of the pumped liquid cools the motor during operation.\u003c\/li\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 always run in a clean environment.\u003c\/li\u003e\n\u003cli\u003eTsurumi Oil Lifter forcibly supplies lubricating oil to the mechanical seal even when the lubricant level falls below the rated volume.\u003c\/li\u003e\n\u003cli\u003eUpper permanently lubricated deep-groove double-shielded C3 ball bearing for motor shaft support.\u003c\/li\u003e\n\u003cli\u003eLower duplex angular contact ball bearing mounted back-to-back to manage heavy high-torque 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":50946659221751,"sku":"300BZ455H","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-300bz455h-cast-iron-water-jacket-submersible-sewage-pump-raw-wastewater-two-channel.png?v=1784259440","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-300bz455h-cast-iron-water-jacket-submersible-sewage-pump-raw-wastewater-two-channel","provider":"Foundation Pumps","version":"1.0","type":"link"}
