This cast iron unit holds CE EN12050-1 certification and is engineered for handling untreated wastewater containing solids. It is suitable for use in civil collection systems with liquid temperatures up to 40°C.\u003c\/p\u003e\u003cp\u003eThe pump incorporates a 24 kW 4-pole motor running at 1490 rpm on a 3 x 415 V supply with a rated current of 56 Amps. It achieves a maximum head up to 26.5 m and a maximum flow up to 13980 L\/min. This model is rated for continuous S1 duty and uses the surrounding liquid for thermal management during operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic design uses an Open S-tube impeller with a 316.5 mm actual diameter. The nominal duty head is 14.28 m. The system features DN 200 inlet and outlet connections following DIN flange standards, supporting high-volume wastewater transfer while reducing the risk of clogging in municipal networks.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the pump features double mechanical shaft seals and integrated PTO sensors for motor protection and monitoring. It is supplied with a 10-metre S1BC4N8-F EMC power cable and features an IP68 enclosure suitable for installation depths up to 30 metres.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen S-tube impeller with a 316.5 mm actual diameter for managing untreated wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for durability in permanent submerged service.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal arrangement with SiC\/SiC primary seal and Silicon Carbide\/Carbon secondary seal.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTO sensors for motor protection and monitoring to ensure stator safety and operational reliability.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in municipal wet wells.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres with a 9 bar maximum operating pressure.\u003c\/li\u003e\n\u003cli\u003eClass H motor insulation with support for up to 30 starts per hour during continuous S1 duty cycles.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos auto-coupling system (96641489) for simplified submerged maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901324792055,"sku":"92850506","price":38248.05,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56m-240-4-50d-200-cast-iron-medium-head-wastewater-pump-open-s-tube-impeller.png?v=1782731450","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56m-240-4-50d-200-cast-iron-medium-head-wastewater-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
