It features a wide discharge bore and a high-flow hydraulic casing designed to transport rainwater and light sewage from deep collection sumps. The pump is suited for wastewater measuring tanks; municipal drainage; and rainwater collection systems.\u003c\/p\u003e\u003cp\u003eThe motor is a 5.5 kW three-phase 415 V dry-type induction motor drawing a rated current of 11.4 Amps. Traced from the official 50Hz manufacturer performance curves; this pump delivers a maximum head of approximately 33 m and a maximum capacity of approximately 1338 L\/Min. The starting method is direct on line; with star-delta starting available on request.\u003c\/p\u003e\u003cp\u003eIts mechanical build features a cast iron semi-open multi-vane impeller that allows free passage of solids up to 15mm in diameter. Sealing is managed by dual-face mechanical seals inside an oil chamber with ceramic-to-carbon upper faces and silicon carbide-to-silicon carbide lower faces. A seal pressure relief port protects the mechanical seal from high pressure.\u003c\/p\u003e\u003cp\u003eWindings are protected by a circle thermal protector inside the watertight housing that shuts the circuit when overcurrent or excess heat is detected. The power cable is an 8-meter chloroprene rubber cabtyre cable with Tsurumi's anti-wicking block. Sump installation and maintenance are made efficient using the optional guide rail set TOS80SF25.5.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSeal pressure relief system that protects mechanical seals from excessive static head at high depths.\u003c\/li\u003e\n\u003cli\u003eCast iron semi-open impeller allowing solids passage up to 15mm in diameter without clogging risk.\u003c\/li\u003e\n\u003cli\u003eCentered oil lifter that forcibly circulates lubricating oil to mechanical seal faces during run-dry cycles.\u003c\/li\u003e\n\u003cli\u003eDeep-groove; double-shielded C3 ball bearings designed for severe radial and axial load distribution.\u003c\/li\u003e\n\u003cli\u003eWaterproof chloroprene rubber cable entry with vulcanized anti-wicking potting inside the entry port.\u003c\/li\u003e\n\u003cli\u003eContinuous-duty dry induction motor with Class F insulation and IP68 protection for absolute submergence.\u003c\/li\u003e\n\u003cli\u003eStandard threaded JIS 10kg\/cm2 flange connection with an 80 mm outlet bore for high-volume piping lines.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50944376570103,"sku":"80SF25.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80sf25-5-cast-iron-high-head-submersible-drainage-pump-for-wastewater-transfer-with-semi-open-impeller.png?v=1784199922","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80sf25-5-cast-iron-high-head-submersible-drainage-pump-for-wastewater-transfer-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
