Holding CE EN12050-1 approval, this cast iron submersible pump is built for permanent installation and handles untreated wastewater containing large solids in civil infrastructure.\u003c\/p\u003e\u003cp\u003eThe unit features a 4 kW 4-pole motor running at 1464 rpm. Operating on a 3 x 415V supply with a rated current of 9.6 Amps, it reaches a maximum flow up to 3066 L\/min and maximum head up to 15.7 m. The motor is designed for continuous S1 submerged service in liquids between 0°C and 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eHandling of untreated wastewater containing solids is managed by an S-tube impeller providing an 80 mm free passage while helping reduce the risk of clogging. Hydraulic design features include a DN 100 inlet and a DN 100 (4\") outlet with DIN flange standards. This configuration supports the pumping of raw effluents through municipal discharge systems.\u003c\/p\u003e\u003cp\u003eConstruction includes an EN-GJL-250 cast iron pump housing and motor casing with double SIC\/SIC mechanical seals. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Protection also includes 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 80 mm free passage for reliable transit of solids-laden wastewater in municipal networks.\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 100 inlet and DN 100 (4\") discharge connection for efficient fluid trajectories in municipal networks.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals with 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\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 municipal wastewater networks and collection systems.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901322203383,"sku":"98625969","price":9078.18,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-80-100-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller.png?v=1782731397","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-80-100-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
