This cast iron model holds CE EN12050-1 certification with ROHS and WEEE environmental approvals. It is developed for handling raw effluents and untreated wastewater containing solids.\u003c\/p\u003e\u003cp\u003eA 21 kW 4-pole motor powers the pump at 1490 rpm on a 3 x 415 V supply. Operating with a rated current of 52.5 Amps, it achieves a maximum flow up to 13200 L\/min and a maximum head up to 26 m. The motor is rated for continuous S1 duty, using the surrounding media for cooling during submerged operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses an Open S-tube impeller with a 308.6 mm actual diameter for solids handling. The nominal duty head is 13.09 m. The hydraulic design features dual DN 200 inlet and outlet connections with DIN flanges, supporting high-volume wastewater transfer while reducing the risk of clogging in municipal infrastructure.\u003c\/p\u003e\u003cp\u003eConstruction features an EN-GJL-250 cast iron pump housing and motor casing with double mechanical shaft seals. Protection includes integrated PTO sensors for motor protection and monitoring. The unit 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 with a 308.6 mm actual diameter for handling untreated wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural integrity in submerged environments.\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 reliable performance and safety.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in sewage basins.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres and 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 submerged service.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos auto-coupling system (96641489) for simplified installation and maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901324693751,"sku":"92850504","price":29739.55,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56m-210-4-50d-200-cast-iron-medium-head-wastewater-pump-open-s-tube-impeller.png?v=1782731447","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56m-210-4-50d-200-cast-iron-medium-head-wastewater-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
