This cast iron unit is intended for permanent installation in civil wet wells and is developed for handling raw effluents containing large solids in high-demand municipal networks.\u003c\/p\u003e\u003cp\u003eThe unit features a 7.5 kW 4-pole motor operating at 1462 rpm on a 3 x 415V supply with a rated current of 14.4 Amps. It achieves a maximum head up to 19.5 m and maximum flow up to 4866 L\/min. The motor is designed for continuous S1 duty in untreated wastewater with temperatures 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 a 100 mm free passage for untreated wastewater containing solids while helping reduce the risk of clogging. Hydraulic connections include a DN 150 inlet and a 4\" (100 mm) outlet with DIN flanges. This single-vane hydraulic path facilitates the conveying of raw effluents through municipal discharge piping.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the unit includes a double mechanical SIC\/SIC seal system. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Motor safety is provided by 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 100 mm free passage for processing wastewater with high solids content.\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 4\" (100 mm) discharge connection for high-volume fluid trajectories in municipal networks.\u003c\/li\u003e\n\u003cli\u003eDouble SIC\/SIC mechanical shaft seals with an oil chamber for redundant moisture defence for the stator.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and thermal monitoring.\u003c\/li\u003e\n\u003cli\u003eBuilt-in thermal switches within the stator windings for automatic protection against electrical damage.\u003c\/li\u003e\n\u003cli\u003e10-metre rugged LYNIFLEX power cable and IP68 enclosure for continuous operation in deep wet wells.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in municipal wastewater systems and centralized lift stations.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901323153655,"sku":"98625987","price":12850.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-100-100-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-systems-with-s-tube-impeller.png?v=1782731410","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-100-100-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-systems-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
