This cast iron unit is intended for municipal and industrial wastewater applications where raw sewage containing solids must be moved reliably. It maintains operational stability in infrastructure environments with liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe unit achieves a maximum head of 26 m and a maximum flow rate of 13980 L\/min using a 24 kW 4-pole motor. Drawing 56 Amps on a 415 V supply, the pump utilizes an internal cooling jacket for thermal safety. This integrated cooling allows for reliable operation during high-capacity transfer cycles in municipal collection systems.\u003c\/p\u003e\u003cp\u003eHydraulic output is driven by an Open S-tube impeller with a 316.5 mm diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 14.28 m. Featuring dual 200 mm inlet and outlet connections with DIN flanges, the design supports high-volume transfer while helping to reduce clogging in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron motor casing and pump housing, featuring a double mechanical SiC\/SiC shaft seal arrangement. Protection features include integrated PTO sensors, moisture switches, and leakage sensors for proactive motor protection and monitoring in utility networks. The unit includes 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 316.5 mm diameter and 71 mm passage for managing solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural durability in permanent service.\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 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 electrical connection in stations.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres and 9 bar operating pressure.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN200 auto-coupling system (96641489) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
