This cast iron unit is intended for permanent installation in civil infrastructure and is suitable for wet wells where untreated wastewater containing large solids must be conveyed effectively.\u003c\/p\u003e\u003cp\u003eThe pump features a 7.5 kW 4-pole motor running at 1462 rpm on a 3 x 415V supply with a rated current of 14.4 Amps. It achieves a maximum flow up to 3300 L\/min and maximum head up to 23.2 m. The motor is designed for continuous S1 submerged service 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\u003eAn S-tube impeller provides an 80 mm free passage for untreated wastewater containing solids while helping reduce the risk of clogging. It utilises a DN 100 inlet and a 4\" (100 mm) outlet with DIN flange connections. This single-vane hydraulic path facilitates the transfer of raw effluents in high-volume municipal networks.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the unit includes a double SIC\/SIC mechanical shaft seal arrangement. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Stator protection includes winding-embedded thermal switches, 10 metres of LYNIFLEX 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 80 mm free passage for reliable transit of large solids-laden wastewater.\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 100 inlet and 4\" (100 mm) discharge connection for high-volume extraction in municipal networks.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC 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 moisture sensors providing proactive early warning of fluid ingress during deep submersion.\u003c\/li\u003e\n\u003cli\u003e10-metre rugged LYNIFLEX power cable and IP68 enclosure for reliable operation in wastewater wet wells.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in municipal wastewater transfer networks and centralized utility sites.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901322399991,"sku":"98625986","price":12005.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-80-100-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-transfer-with-s-tube-impeller.png?v=1782731402","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-80-100-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
