Utilizing a multi-vane hydraulic configuration; it easily transports clear or light effluent to distant locations or municipal lines. It is suitable for underground rainwater tanks; municipal treatment facilities; and measuring tanks.\u003c\/p\u003e\u003cp\u003eThe continuous-duty dry motor runs on a 415 V three-phase supply and outputs 0.75 kW while drawing a rated current of 2.0 Amps. Based on the manufacturer's performance curve; this pump achieves a maximum total head of approximately 15.2 m and a maximum capacity of approximately 330 L\/Min. The unit operates with direct on line starting at a speed of 3000 min-1.\u003c\/p\u003e\u003cp\u003eBuilt with a semi-open multi-vane impeller; the hydraulic design handles soft solids up to 11mm in diameter without clogging. The dual mechanical shaft seals are located within an oil chamber and incorporate ceramic-to-carbon upper and silicon carbide-to-ceramic lower seal faces. A patented centrifugal oil lifter forcibly circulates lubricant across the seal faces.\u003c\/p\u003e\u003cp\u003eMotor safety is provided by a circle thermal protector that directly opens the motor circuit during excessive heat or overcurrent events. Power is supplied through a 6-meter PVC cabtyre cable which features Tsurumi's anti-wicking entry block to prevent water migration. This free-standing model can be adapted to guide rails using the optional TOK4-A system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCast iron semi-open multi-vane impeller designed for reliable light solids passage up to 11mm size.\u003c\/li\u003e\n\u003cli\u003eTsurumi Tsurumi Oil Lifter device that stabilizes double mechanical seal cooling and prevents dry running.\u003c\/li\u003e\n\u003cli\u003eWaterproof cable connection incorporating an epoxy-resin anti-wicking block that halts capillary fluid transport.\u003c\/li\u003e\n\u003cli\u003ePermanently lubricated; double-shielded C3 ball bearings to support continuous operation and low noise.\u003c\/li\u003e\n\u003cli\u003eHigh-tensile 420 stainless steel motor shaft and gray cast iron motor frame for long-lasting alignment.\u003c\/li\u003e\n\u003cli\u003eDry-type subsea induction motor rated under IP68 protection class with high-grade winding insulation.\u003c\/li\u003e\n\u003cli\u003eThreaded oval flange discharge connection with 50 mm discharge bore size for direct piping attachment.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50944376406263,"sku":"50SF2.75","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-50sf2-75-cast-iron-high-head-submersible-drainage-pump-for-treated-water-transfer-with-semi-open-impeller.png?v=1784199912","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-50sf2-75-cast-iron-high-head-submersible-drainage-pump-for-treated-water-transfer-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
