Holding CE EN12050-1 approval, this cast iron unit is built for submerged installation in storm basins and wet wells. It is designed for high-volume environments requiring reliable wastewater transfer.\u003c\/p\u003e\u003cp\u003ePerformance is driven by a 4 kW 4-pole motor operating at 1464 rpm on a 3 x 415V supply with a rated current of 9.6 Amps. It achieves a maximum head up to 11.2 m and flow up to 3864 L\/min. The unit is rated for continuous S1 submerged service in untreated wastewater at temperatures up to 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic design incorporates an S-tube impeller providing a 100 mm free passage for untreated wastewater while helping reduce the risk of clogging. The pump utilises a DN 150 inlet and a 6\" (150 mm) outlet with DIN flange standards. This configuration supports the transfer of raw effluents in municipal collection networks.\u003c\/p\u003e\u003cp\u003eConstruction consists of an EN-GJL-250 cast iron pump housing and motor casing. Shaft protection is provided by a double mechanical SIC\/SIC arrangement and integrated PTC thermal sensors for motor monitoring. Integrated moisture sensors are used for seal and motor monitoring, along with 10 metres of LYNIFLEX power cable and an IP68 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 handling large solids-laden wastewater without clogging.\u003c\/li\u003e\n\u003cli\u003e4 kW 4-pole motor operating at 1464 rpm on a 3 x 415V three-phase supply with 9.6 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and 6\" (150 mm) discharge connection for rapid high-volume fluid relocation.\u003c\/li\u003e\n\u003cli\u003eDouble SIC\/SIC mechanical shaft seals in an oil chamber for redundant moisture defence for the motor.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.\u003c\/li\u003e\n\u003cli\u003eWinding-integrated thermal switches for automatic motor safety and overheating protection in wet wells.\u003c\/li\u003e\n\u003cli\u003e10-metre heavy-duty LYNIFLEX power cable and IP68 protection classification for deep-well operation.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in large-scale pumping stations and volume-intensive wastewater networks.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901323219191,"sku":"98625971","price":10678.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-100-150-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-pumping-stations-with-s-tube-impeller.png?v=1782731413","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-100-150-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-pumping-stations-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
