With an 80mm discharge bore and semi-open impeller; it is designed for rapid discharge under high-head conditions. It is suitable for rainwater pumping; stormwater basins; and treated water discharge.\u003c\/p\u003e\u003cp\u003eThe heavy-duty motor operates on a three-phase 415 V power supply; delivering 7.5 kW of power and drawing a rated current of 14.6 Amps. According to the manufacturer's 50Hz performance curve; the pump achieves a maximum total head of approximately 38 m and a maximum flow rate of approximately 1800 L\/Min. Direct on line starting is standard; with star-delta starting optional.\u003c\/p\u003e\u003cp\u003eConstructed with a dynamically balanced semi-open cast iron impeller; it allows free passage of solid matters up to 19mm in diameter. Sealing is managed by a double mechanical seal in an oil chamber featuring ceramic-to-carbon upper faces and silicon carbide-to-silicon carbide lower faces. A seal pressure relief port isolates the seals from pump discharge pressures.\u003c\/p\u003e\u003cp\u003eMotor winding safety is ensured by a circle thermal protector built into the watertight housing that shuts the circuit during overcurrent or excess heat. The electrical connection is an 8m chloroprene rubber cable featuring Tsurumi's anti-wicking block. Sump maintenance and retrieval can be simplified with the optional guide rail set model TOS80SF27.5.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIndependent seal pressure relief port protecting mechanical seals from discharge pressure at deep depths.\u003c\/li\u003e\n\u003cli\u003eCast iron semi-open impeller allowing free passage of solid matters up to 19mm under continuous load.\u003c\/li\u003e\n\u003cli\u003eWater-tight chloroprene rubber cable entry incorporating a molded anti-wicking block for cable safety.\u003c\/li\u003e\n\u003cli\u003eCentrifugal oil lifter forcibly lubricating upper seal faces in run-dry states to extend operation periods.\u003c\/li\u003e\n\u003cli\u003eDouble-shielded deep-groove C3 ball bearings rated for heavy-duty industrial runtimes under stress.\u003c\/li\u003e\n\u003cli\u003eContinuous-duty squirrel-cage induction motor rated with IP68 protection class and premium F-class windings.\u003c\/li\u003e\n\u003cli\u003eStandard threaded JIS 10kg\/cm2 flange connection with an 80 mm discharge bore for large diameter fittings.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50944376602871,"sku":"80SF27.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80sf27-5-cast-iron-high-head-submersible-drainage-pump-for-treated-water-transfer-with-semi-open-impeller.png?v=1784199925","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80sf27-5-cast-iron-high-head-submersible-drainage-pump-for-treated-water-transfer-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
