This cast iron unit holds CE EN12050-1 certification with ROHS and WEEE approvals. It is developed for handling untreated wastewater containing solids in civil drainage networks.\u003c\/p\u003e\u003cp\u003eAn 18.5 kW 6-pole motor running at 990 rpm powers the pump on a 3 x 415 V supply with a rated current of 48 Amps. It achieves a maximum flow up to 20940 L\/min and a maximum head up to 15 m. The unit is rated for continuous S1 duty in untreated wastewater at temperatures between 0°C and 40°C.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses an Open S-tube impeller with a 379.4 mm actual diameter to manage solids in untreated wastewater. The nominal duty head is 8.28 m. The pump features DN 300 inlet and outlet connections, supporting high-volume wastewater transfer while reducing the risk of clogging in high-capacity drainage networks.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the unit includes 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 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 design with 379.4 mm diameter for handling untreated wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for durability in permanent submerged basins.\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 within the stator for operational safety.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in municipal basins.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres with a 5 bar operating pressure limit.\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\u003eDN 300 inlet and outlet connections optimized for high-volume wastewater transfer in drainage networks.\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901325152503,"sku":"92850522","price":34465.04,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56l-185-6-50d-300-cast-iron-low-head-stormwater-pump-open-s-tube-impeller.png?v=1782731459","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56l-185-6-50d-300-cast-iron-low-head-stormwater-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
