This cast iron model is intended for municipal and industrial wastewater applications, specifically managing untreated sewage containing solids. It provides consistent service in infrastructure sites where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum flow of 13200 L\/min and a maximum head of 26 m, powered by a 21 kW 4-pole motor. Drawing 52.5 Amps on a 415 V supply, the unit utilizes an internal cooling jacket for thermal safety. This setup ensures that hydraulic power remains stable in both wet and dry installation configurations within wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eFluid movement is managed by an Open S-tube impeller with a 308.6 mm actual diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 13.09 m. The design incorporates dual 200 mm inlet and outlet connections with DIN flanges, supporting high-capacity transfer while reducing clogging risks in municipal collection systems.\u003c\/p\u003e\u003cp\u003eStructural durability is provided 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 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 308.6 mm diameter and 71 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 facilitating thermal stability in submerged or dry pit environments.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in basins.\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.
