This cast iron pump is intended for municipal and industrial wastewater applications, providing reliable transfer of untreated wastewater containing solids. It maintains operational safety in permanent infrastructure where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe unit achieves a maximum flow of 7860 L\/min and a maximum head of 40 m while drawing 52.5 Amps from a 415 V supply. Performance is driven by a 21 kW 4-pole motor running at 1490 rpm. An internal cooling jacket system facilitates thermal management, ensuring the motor operates effectively in both submerged and dry pit configurations within municipal collection systems.\u003c\/p\u003e\u003cp\u003eHydraulic dynamics are managed by an Open S-tube impeller with a 340.8 mm diameter and a 41 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 23.26 m. Featuring a 200 mm inlet and a 150 mm outlet with DIN flanges, this configuration supports high-volume transfer while reducing the risk of clogging in discharge networks.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by the EN-GJL-250 cast iron casing and double SiC\/SiC mechanical shaft seals. Safety systems include integrated PTO sensors, leakage sensors, and moisture switches for proactive motor protection and monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure for depths 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 340.8 mm diameter and 41 mm passage for managing 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 seal.\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 enabling 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 and 10 bar maximum pressure.\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.
