It features a high-head hydraulic profile that efficiently lifts water from deep underground sumps or transfers it over long distances. Suitable applications include treated water deforming; rainwater dewatering; and general sump drainage.\u003c\/p\u003e\u003cp\u003eThe motor operates on a 415 V three-phase power supply; delivering 1.5 kW of power and drawing a rated running current of 3.5 Amps. Traced from the 50Hz manufacturer performance curve; it achieves a maximum head of approximately 22 m and a maximum flow rate of approximately 540 L\/Min. This 2-pole induction motor starts direct on line and runs at 3000 min-1.\u003c\/p\u003e\u003cp\u003eIts hydraulic casing features a cast iron semi-open multi-vane impeller that allows a free passage of solids up to 11mm in diameter. The shaft is sealed with a double mechanical seal in an oil chamber with ceramic-to-carbon upper faces and silicon carbide-to-silicon carbide lower faces. A built-in oil lifter supplies lubricant to the seal faces even under low oil volumes.\u003c\/p\u003e\u003cp\u003eMotor protection is maintained by a circle thermal protector built into the watertight housing that shuts the circuit if overcurrent or heat builds up. The power cable is a 6-meter PVC sheath cable featuring an anti-wicking block at the entry section. Sump installation and maintenance can be simplified by utilizing the optional guide rail set model TOS3-50.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCast iron semi-open impeller designed for efficient high-head drainage of light solids and defoaming.\u003c\/li\u003e\n\u003cli\u003eTsurumi's patented centrifugal oil lifter that continuously cools mechanical seal faces and ensures sealing.\u003c\/li\u003e\n\u003cli\u003eWater-tight cable entry incorporating a vulcanized rubber anti-wicking block that stops moisture wicking.\u003c\/li\u003e\n\u003cli\u003ePermanently lubricated; deep-groove; double-shielded C3 ball bearings supporting smooth rotational speeds.\u003c\/li\u003e\n\u003cli\u003e420 stainless steel motor shaft for optimal structural durability and protection against shaft distortion.\u003c\/li\u003e\n\u003cli\u003eContinuous-duty dry induction motor rated with IP68 protection and Class F insulation for hostile sumps.\u003c\/li\u003e\n\u003cli\u003eThreaded JIS 10kg\/cm2 flange connection with a 50 mm discharge bore for secure connection fittings.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50944376471799,"sku":"50SF21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-50sf21-5-cast-iron-guide-rail-compatible-drainage-pump-for-wastewater-treatment-with-semi-open-impeller.png?v=1784199915","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-50sf21-5-cast-iron-guide-rail-compatible-drainage-pump-for-wastewater-treatment-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
