This cast iron submersible pump is intended for municipal and industrial wastewater applications where raw sewage containing solids must be moved reliably. It is engineered for service in infrastructure environments where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum head of 17 m and a maximum flow up to 23820 L\/min while drawing 55 Amps from a 415 V supply. Performance is driven by a 24.5 kW 6-pole motor running at 990 rpm. An internal cooling jacket system facilitates thermal safety, ensuring the motor operates effectively in both submerged and dry pit environments within wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eHydraulic handling is managed by an Open S-tube impeller with a 400.5 mm actual diameter and a 105 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 9.69 m. Featuring dual 300 mm inlet and outlet connections, the design supports high-capacity transfer while reducing the risk of clogging in municipal collection systems.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing paired with double SiC\/SiC mechanical shaft seals. Safety is monitored by integrated PTO sensors, moisture switches, and leakage sensors for proactive motor protection and monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure.\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 diameter and 105 mm passage for managing raw effluents.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for structural integrity in infrastructure.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SiC\/SiC primary faces and Silicon Carbide\/Carbon barrier protection.\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 facilitating thermal management 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 and 5 bar maximum pressure limit.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN300 auto-coupling system (96255839) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
