This cast iron submersible pump is intended for municipal and industrial wastewater applications where raw sewage contains solids. It provides consistent hydraulic service at liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum flow of 9600 L\/min and a maximum head of 43 m, powered by a 24 kW 4-pole motor drawing 56 Amps. Working on a three-phase 415 V supply, the motor utilizes an internal cooling jacket system for temperature control. This setup facilitates stable temperature management for reliable hydraulic power in high-head lift systems.\u003c\/p\u003e\u003cp\u003eManaging untreated wastewater containing solids is the primary function of the Open S-tube impeller, featuring a 351 mm diameter and a 41 mm free passage. The nominal duty head is 24.9 m. This hydraulic design incorporates a 200 mm inlet and a 150 mm outlet with DIN flanges, supporting high-volume transfer while reducing clogging risks in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing with double mechanical SiC\/SiC shaft seals. Integrated PTO sensors, moisture switches, and leakage sensors provide motor protection and monitoring to ensure operational safety. The unit includes a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure 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 351 mm diameter and 41 mm passage for managing untreated wastewater.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for durability in permanent installations.\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 facilitates 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 electrical connection in stations.\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 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.
