Holding CE EN12050-1 approval, this unit is built for municipal wet wells and basins prone to untreated wastewater containing large solids. It is developed for handling raw effluents in high-demand networks.\u003c\/p\u003e\u003cp\u003eOperating on a 3 x 415V supply with a rated current of 14.4 Amps, this model features a 7.5 kW 4-pole motor operating at 1462 rpm. It achieves a maximum head up to 19.4 m and maximum flow up to 4998 L\/min. The motor is designed for continuous S1 duty in untreated wastewater at temperatures between 0°C and 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 100 mm while helping reduce the risk of clogging. The hydraulic design features a DN 150 inlet and a 6\" (150 mm) outlet with DIN flange standards. This configuration supports high-volume fluid transfer in municipal wastewater systems.\u003c\/p\u003e\u003cp\u003eConstruction features EN-GJL-250 cast iron for the pump housing and motor casing. Protection includes a double SIC\/SIC mechanical shaft seal arrangement and integrated PTC thermal sensors for motor monitoring. Integrated moisture sensors are included for seal and motor monitoring, along with a 10-metre LYNIFLEX cable and 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 100 mm free passage for processing large solids-laden wastewater without clogging.\u003c\/li\u003e\n\u003cli\u003e7.5 kW 4-pole motor operating at 1462 rpm on a 3 x 415V three-phase supply with 14.4 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and 6\" (150 mm) discharge connection for large-scale wastewater relocation.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals with an oil chamber for redundant moisture defence for the shaft.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.\u003c\/li\u003e\n\u003cli\u003eBuilt-in thermal switches within the stator windings for automatic protection against electrical overheating.\u003c\/li\u003e\n\u003cli\u003e10-metre rugged LYNIFLEX power cable and IP68 moisture protection for deep submerged operation.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in high-volume wastewater transfer and demanding relocation sites.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901323481335,"sku":"98625988","price":13009.79,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-100-150-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-high-volume-transfer-with-s-tube-impeller.png?v=1782731420","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-100-150-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-high-volume-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
