This cast iron submersible pump holds CE EN12050-1 certification with ROHS and WEEE environmental approvals. It is suitable for lift stations and collection systems handling raw effluents and untreated wastewater.\u003c\/p\u003e\u003cp\u003eA 24 kW 4-pole motor powers the unit at 1490 rpm on a 3 x 415 V supply with a rated current of 56 Amps. The pump achieves a maximum head up to 43 m and a maximum flow up to 9600 L\/min. This model is rated for continuous S1 submerged service in liquids between 0°C and 40°C, using the surrounding media for motor cooling.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses an Open S-tube impeller with a 351 mm actual diameter to manage untreated wastewater containing solids. The nominal duty head is 24.9 m. The hydraulic design features a DN 200 inlet and a DN 100 outlet, supporting high-volume wastewater transfer while reducing the risk of clogging in municipal discharge systems.\u003c\/p\u003e\u003cp\u003eConstruction features an EN-GJL-250 cast iron pump housing and motor casing with 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. The pump is compatible with the Grundfos auto-coupling system (96090994).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen S-tube impeller with a 351 mm actual diameter designed for managing untreated wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural integrity 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 prevent electrical overheating and failure.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in lift stations.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres and 10 bar maximum operating pressure.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos auto-coupling system (96090994) for simplified submerged installation.\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\u003c\/ul\u003e ","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901323743479,"sku":"92955428","price":33139.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56h-240-4-50d-100-cast-iron-high-head-sewage-pump-open-s-tube-impeller.png?v=1782731428","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56h-240-4-50d-100-cast-iron-high-head-sewage-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
