This cast iron model is intended for municipal and industrial wastewater applications where raw sewage contains solids. It is engineered to maintain performance in utility networks with liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum flow of 14880 L\/min and a maximum head of 30 m while powered by a 28 kW 4-pole motor. Operating on a 415 V supply with 60.5 Amps, the unit incorporates an internal cooling jacket for temperature control. This setup facilitates stable thermal management for high-capacity pumping in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eCentral to its hydraulic performance is the Open S-tube impeller with a 326 mm diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 15.77 m. Featuring dual 200 mm inlet and outlet connections with DIN flanges, this hydraulic configuration supports high-volume transfer while helping to reduce the risk of clogging in municipal collection systems.\u003c\/p\u003e\u003cp\u003eStructural integrity is maintained by the EN-GJL-250 cast iron casing and 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 suitable for installation 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 326 mm diameter and 71 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 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 enables stable 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 with a 9 bar operating limit.\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.
