This cast iron submersible pump holds CE EN12050-2 approval and is built for treatment plants and centralized sumps. It is suitable for conveying untreated wastewater through discharge piping in civil environments.\u003c\/p\u003e\u003cp\u003eThis model features a 4 kW 2-pole motor running at 2930 rpm. Operating on a 3 x 415V supply with a rated current of 8.2 Amps, it provides a maximum head up to 26 m and a maximum flow up to 1164 L\/min. The motor is rated for continuous S1 duty in untreated wastewater with a temperature range of 0°C to 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eThe S-tube impeller is designed for untreated wastewater containing solids up to 50 mm while helping reduce the risk of clogging. The unit includes a DN 65 inlet and a DN 80 (3\") outlet with DIN flanges. This configuration supports the transfer of untreated effluents in industrial transfer sequences.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the unit features a double SIC\/SIC mechanical shaft seal arrangement. Integrated moisture sensors are used for seal and motor monitoring. Protection includes PTC sensors, winding-embedded thermal switches, 10 metres of LYNIFLEX power cable, and an IP68 enclosure rating. The pump is suitable for installation depths up to 7 metres.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eS-tube impeller with 50 mm free passage for reliable transit of solids-laden water in industrial applications.\u003c\/li\u003e\n\u003cli\u003e4 kW 2-pole motor operating at 2930 rpm on a 3 x 415V three-phase supply with 8.2 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eHigh-head performance up to 26 m for high-pressure wastewater relocation in treatment plants and sumps.\u003c\/li\u003e\n\u003cli\u003eDN 65 inlet and DN 80 (3\") discharge connection with DIN flange standards for industrial piping infrastructure.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals with an oil chamber for redundant moisture defence against fluid infiltration.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.\u003c\/li\u003e\n\u003cli\u003eClass H stator insulation and IP68 protection classification for safe, deep-well submerged operation.\u003c\/li\u003e\n\u003cli\u003e10-metre heavy-duty LYNIFLEX power cable for flexible installation in deep wastewater sumps and wet wells.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901321482487,"sku":"98626077","price":6088.59,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-50-80-40-2-50b-c-cast-iron-2-pole-wastewater-pump-for-industrial-effluent-with-s-tube-impeller.png?v=1782731372","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-50-80-40-2-50b-c-cast-iron-2-pole-wastewater-pump-for-industrial-effluent-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
