Engineered with an 80mm discharge connection; it efficiently moves high-head flows containing small solid matters. Typical applications include treated water deforming; rainwater sumps; and deep dewatering operations.\u003c\/p\u003e\n\u003cp\u003eThe dry induction motor runs on a 415 V three-phase power source; delivering 11 kW of output while drawing a rated current of 22.8 Amps. Based on the manufacturer's official 50Hz performance curves; the pump achieves a maximum total head of approximately 45 m and a maximum flow rate of approximately 1878 L\/Min. This model utilizes star-delta starting for soft starting.\u003c\/p\u003e\n\u003cp\u003eThe pump features a dynamically balanced semi-open cast iron impeller allowing free passage of solids up to 22mm. The shaft is sealed by a double-face mechanical seal in an oil chamber with ceramic-to-carbon upper faces and silicon carbide-to-silicon carbide lower faces. A seal pressure relief system vents excessive static pressure away from the seal faces.\u003c\/p\u003e\n\u003cp\u003eMotor winding safety is provided by miniature thermal protectors embedded in each winding phase that shut down the power supply via a control panel. Power is supplied via heavy-duty chloroprene rubber cabtyre cables featuring an anti-wicking block at the entry. Sump maintenance and regular inspection are simplified by using the optional guide rail set TOS80SF211.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated seal pressure relief port designed to optimize mechanical seal life and reduce wear.\u003c\/li\u003e\n\u003cli\u003eCast iron semi-open multi-vane impeller enabling solid passage of up to 22mm without blockage risk.\u003c\/li\u003e\n\u003cli\u003eCentrifugal oil lifter ensuring complete lubrication to seal faces in low oil states or horizontal layouts.\u003c\/li\u003e\n\u003cli\u003eMiniature thermal protectors (MTP) embedded in each winding phase for proactive electrical safety.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty chloroprene rubber watertight cables incorporating an anti-wicking block that stops moisture.\u003c\/li\u003e\n\u003cli\u003eContinuous-duty dry-type squirrel-cage induction motor with IP68 protection and Class F thermal rating.\u003c\/li\u003e\n\u003cli\u003eStandard threaded JIS 10kg\/cm2 flange connection with an 80 mm discharge bore for heavy utility piping.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50944376635639,"sku":"80SF211","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80sf211-cast-iron-high-head-submersible-wastewater-pump-for-underground-drainage-with-semi-open-impeller.png?v=1784199927","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80sf211-cast-iron-high-head-submersible-wastewater-pump-for-underground-drainage-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
