This cast iron model is certified under CE EN12050-1 with ROHS and WEEE approvals. It is intended for permanent submerged installation in transfer stations requiring raw effluent handling between 0°C and 40°C.\u003c\/p\u003e\u003cp\u003ePerformance is delivered by a 24.5 kW 6-pole motor operating at 990 rpm on a 3 x 415 V supply with a rated current of 55 Amps. The pump achieves a maximum head up to 17 m and a maximum flow up to 23820 L\/min. The motor is designed for continuous S1 duty, utilizing the surrounding liquid for cooling during submerged operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses an Open S-tube impeller with a 400.5 mm actual diameter for managing untreated wastewater containing solids. The nominal duty head is 9.69 m. The design features DN 300 inlet and outlet connections for high-capacity wastewater transfer while reducing the risk of clogging in civil collection networks.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the pump features a double mechanical shaft seal arrangement 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 with a 400.5 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 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 operational reliability and safety.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in transfer stations.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres and 5 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\u003eDN 300 inlet and outlet connections optimized for high-capacity wastewater handling in municipal networks.\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901324529911,"sku":"92955434","price":39852.51,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56h-360-4-50d-150-cast-iron-high-head-wastewater-pump-open-s-tube-impeller.png?v=1782731443","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56h-360-4-50d-150-cast-iron-high-head-wastewater-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
