This cast iron unit is intended for municipal and industrial wastewater applications where consistent transfer is required for raw sewage containing solids. It maintains operational stability in environments with liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum flow of 7860 L\/min and a maximum head of 40 m while powered by a 21 kW 4-pole motor. Operating on a three-phase 415 V supply with a 52.5 Amp rated current, the unit incorporates an internal cooling jacket for temperature management. This configuration ensures that hydraulic power remains stable in both wet and dry installation setups.\u003c\/p\u003e\u003cp\u003eFluid movement is managed by an Open S-tube impeller with a 340.8 mm actual 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 100 mm outlet with DIN flanges, the hydraulic design supports high-volume transfer while reducing the risk of clogging in discharge piping.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing paired with a double mechanical SiC\/SiC shaft seal. Protection is managed by integrated PTO sensors, moisture switches, and leakage sensors to monitor internal conditions within wastewater infrastructure. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and is compatible with the Grundfos DN100 auto-coupling system (96090994).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen S-tube impeller with 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 installations.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SiC\/SiC primary seal 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 submerged or dry pits.\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 10 bar operating limit.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN100 auto-coupling system (96090994) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
