This cast iron submersible pump is intended for municipal and industrial wastewater applications, specifically managing raw sewage and untreated effluents containing solids. It provides reliable performance in permanent installations with liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum head of 46 m and a maximum flow of 9180 L\/min when powered by a 28 kW 4-pole motor. Drawing 60.5 Amps on a 415 V supply, the unit utilizes an internal cooling jacket for temperature control. This setup facilitates stable hydraulic output for wastewater infrastructure requiring consistent transfer between stations.\u003c\/p\u003e\u003cp\u003eHydraulic handling is characterized by an Open S-tube impeller with a 363.2 mm diameter and a 41 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 26.85 m. Equipped with a 200 mm inlet and a 100 mm outlet, the design supports high-volume transfer through high-pressure discharge piping in municipal collection systems.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing, using a double SiC\/SiC mechanical shaft seal for redundant motor protection. Operational safety is ensured by integrated PTO sensors, moisture switches, and leakage sensors for comprehensive monitoring. The unit includes a 10-metre S1BC4N8-F EMC power cable and an IP68 rated enclosure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen S-tube impeller with 363.2 mm diameter and 41 mm passage for managing solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for durability in permanent service.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SiC\/SiC primary faces and Silicon Carbide\/Carbon secondary barrier.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTO sensors, moisture switches, and leakage sensors for motor protection and monitoring.\u003c\/li\u003e\n\u003cli\u003eInternal cooling jacket system for thermal management in both submerged and dry pit environments.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable connection in transfer stations.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres and 10 bar operating pressure.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN100 auto-coupling system (96090994) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
