This cast iron pump holds CE EN12050-1 approval and is used for pumping untreated wastewater containing large solids. It is designed for handling raw effluents in civil utility networks.\u003c\/p\u003e\u003cp\u003eThe pump is powered 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 16 m and maximum flow up to 2952 L\/min. The unit is rated for continuous S1 submerged duty in untreated wastewater 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 80 mm while helping reduce the risk of clogging. Hydraulic connection sizes include a DN 100 inlet and a DN 80 (3\") outlet with DIN flange standards. This single-vane design facilitates the conveying of untreated effluents through discharge piping.\u003c\/p\u003e\u003cp\u003eConstruction features an EN-GJL-250 cast iron pump housing and motor casing with double SIC\/SIC mechanical shaft seals. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Stator protection is provided by thermal switches in the windings, a 10-metre 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 processing contaminated fluids without clogging 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 80 (3\") discharge connection for high-volume extraction in municipal wet wells.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals in an oil chamber providing a redundant moisture barrier 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 water-in-oil sensor providing early warning of potential fluid ingress into the internal oil chamber.\u003c\/li\u003e\n\u003cli\u003e10-metre heavy-duty LYNIFLEX power cable and IP68 rated enclosure for deep submerged service in lift stations.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in municipal lift stations and centralized wastewater relocation sites.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901321810167,"sku":"98625968","price":8798.35,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-80-80-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller.png?v=1782731381","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-80-80-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
