This cast iron pump holds CE EN12050-1 certification with ROHS and WEEE approvals. It is suitable for handling raw effluents and untreated wastewater containing solids at temperatures between 0°C and 40°C.\u003c\/p\u003e\u003cp\u003eThe pump incorporates a 41 kW 4-pole motor running at 1485 rpm on a 3 x 415 V supply with a rated current of 78 Amps. It achieves a maximum head up to 37 m and a maximum flow up to 17340 L\/min. The motor is rated for continuous S1 duty and utilizes the surrounding pumped liquid for thermal cooling.\u003c\/p\u003e\u003cp\u003eThe hydraulic design uses an Open S-tube impeller with a 351 mm actual diameter for managing untreated wastewater. The nominal duty head is 20.03 m. The pump incorporates dual DN 200 connections with DIN flanges, supporting high-volume wastewater transfer while reducing the risk of clogging in commercial 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 a 351 mm actual diameter for handling untreated wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for permanent submerged wet well 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 within the windings for reliability.\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 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 duty.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos auto-coupling system (96641489) for maintenance access in deep basins.\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901325086967,"sku":"92850541","price":53973.81,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl-56m-410-4-50d-200-cast-iron-medium-head-wastewater-pump-open-s-tube-impeller.png?v=1782731457","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl-56m-410-4-50d-200-cast-iron-medium-head-wastewater-pump-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
