This cast iron model is intended for municipal and industrial wastewater applications, specifically managing raw sewage containing solids. It maintains operational safety in utility networks where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum head of 45 m and a maximum flow of 9180 L\/min when powered by a 32 kW 4-pole motor. Drawing 65.5 Amps on a 415 V supply, the unit utilizes an internal cooling jacket for temperature management. This setup ensures that hydraulic output remains stable during prolonged pumping cycles in high-head collection sumps.\u003c\/p\u003e\u003cp\u003eFluid movement is managed by an Open S-tube impeller with a 371.2 mm diameter and a 44 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 27.64 m. Featuring a 200 mm inlet and a 150 mm outlet with DIN flanges, this configuration 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 pump housing and motor casing protected by double SiC\/SiC mechanical shaft seals. Safety is monitored by integrated PTO sensors, moisture switches, and leakage sensors for comprehensive motor health monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure for depths up 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 371.2 mm diameter and 44 mm passage for managing untreated wastewater.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for structural durability in permanent stations.\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 facilitates stable thermal management in both submerged and dry pits.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable connection in grid systems.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 30 metres and 10 bar operating 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.
