This cast iron unit is intended for municipal and industrial wastewater applications specifically designed for managing raw sewage containing solids. It maintains operational safety in infrastructure environments where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe unit achieves a maximum flow rate of 17340 L\/min and a maximum head of 36 m using a 41 kW 4-pole motor. Operating on a 415 V supply with 78 Amps, the pump uses an internal cooling jacket for temperature control. This integrated system ensures that thermal stability remains high during high-capacity transfer in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eDynamics are controlled by an Open S-tube impeller with a 351 mm diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 20.03 m. With dual 200 mm inlet and outlet DIN flange connections, the configuration supports high-volume transfer while helping to reduce clogging in municipal collection systems.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron motor casing and pump housing with a double mechanical shaft seal system. Motor safety is monitored by integrated PTO sensors, moisture switches, and leakage sensors for operational reliability in grid systems. 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 351 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 durability in permanent service.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SiC\/SiC primary faces and Silicon Carbide\/Carbon barrier protection.\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 supports reliable temperature control in both submerged and 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 9 bar maximum pressure.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN200 auto-coupling system (96641489) for simplified submerged access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
