This cast iron unit holds CE EN12050-1 certification and is suitable for treatment facilities and industrial sumps. It is developed for handling untreated wastewater containing solids at temperatures up to 40°C.\u003c\/p\u003e\u003cp\u003eThe pump features a 21 kW 4-pole motor operating at 1490 rpm on a 3 x 415 V supply. It achieves a maximum flow up to 7860 L\/min and a maximum head up to 40 m with a rated current of 52.5 Amps. The system is rated for continuous S1 duty, with thermal management provided by the surrounding liquid during operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses an Open S-tube impeller with a 340.8 mm actual diameter to handle solids-laden untreated wastewater. The nominal duty head is 23.26 m. The hydraulic design incorporates a DN 200 inlet and a DN 150 (6\") outlet, supporting high-volume wastewater transfer while reducing the risk of clogging in industrial collection systems.\u003c\/p\u003e\u003cp\u003eConstruction features an EN-GJL-250 cast iron pump housing and motor casing with double mechanical shaft seals. Protection is provided by 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 340.8 mm actual diameter for managing untreated wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural durability in industrial 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 operational reliability and safety.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection.\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 (97695489) for simplified maintenance and 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":50901323907319,"sku":"92955430","price":33139.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56h-210-4-50d-150-cast-iron-high-head-industrial-wastewater-pump-open-s-tube-impeller.png?v=1782731433","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56h-210-4-50d-150-cast-iron-high-head-industrial-wastewater-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
