This cast iron unit is intended for municipal and industrial wastewater applications where raw sewage containing solids must be moved reliably. It maintains operation in environments with liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe unit achieves a maximum flow rate of 9180 L\/min and a maximum head of 46 m using a 28 kW 4-pole motor. Operating on a three-phase 415 V supply with 60.5 Amps, the pump uses an internal cooling jacket for thermal safety. This integrated system ensures that temperature control remains stable during high-capacity transfer in municipal collection systems.\u003c\/p\u003e\u003cp\u003eHydraulic output is driven 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. With a 200 mm inlet and a 150 mm outlet, the configuration supports high-volume transfer while helping to reduce clogging in wastewater infrastructure discharge networks.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing, featuring a double mechanical shaft seal system. Integrated PTO sensors, moisture switches, and leakage sensors monitor internal motor health to prevent failure in centralized sumps. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and is rated IP68 for 30 metres depth.\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 untreated solids.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for structural integrity in utility networks.\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 supports thermal stability in both wet and dry installations.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in sumps.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres with a 10 bar pressure rating.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN150 auto-coupling system (97695489) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
