This cast iron submersible pump is built for permanent installation in civil infrastructure wet wells. It is intended for handling raw wastewater containing large solids in municipal and industrial collection networks.\u003c\/p\u003e\u003cp\u003eA 5.5 kW 4-pole motor running at 1463 rpm on a 3 x 415V supply with a rated current of 10.9 Amps powers the pump. It achieves a maximum head up to 16.6 m and maximum flow up to 4332 L\/min. The motor is designed for continuous S1 duty in untreated wastewater containing solids at temperatures up to 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eHandling of untreated wastewater is facilitated by an S-tube impeller providing a 100 mm free passage while helping reduce the risk of clogging. The unit is equipped with a DN 150 inlet and a 6\" (150 mm) outlet with DIN flange connections. This single-vane hydraulic path supports the transfer of raw effluents in demanding collection systems.\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 system. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Protection also includes thermal switches in the windings, 10 metres of LYNIFLEX power cable, and an IP68 enclosure rating for submerged service. 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\u003e5.5 kW 4-pole motor operating at 1463 rpm on a 3 x 415V three-phase supply with 10.9 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and 6\" (150 mm) discharge connection for efficient large-scale fluid relocation.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC 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\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 reliable operation in deep wet wells.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in wastewater collection networks and civil infrastructure drainage systems.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901323383031,"sku":"98626064","price":11607.49,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-100-150-55-4-50b-c-cast-iron-4-pole-wastewater-pump-for-collection-networks-with-s-tube-impeller.png?v=1782731416","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-100-150-55-4-50b-c-cast-iron-4-pole-wastewater-pump-for-collection-networks-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
