This cast iron submersible pump is intended for municipal and industrial wastewater applications where raw sewage containing solids must be moved reliably. It maintains operational stability in environments where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe unit achieves a maximum head of 50 m and a maximum flow up to 12180 L\/min while powered by a 41 kW 4-pole motor. Operating on a 415 V supply with 78 Amps, the pump incorporates an internal cooling jacket for thermal management. This system ensures temperature stability for high-capacity performance in demanding municipal collection systems.\u003c\/p\u003e\u003cp\u003eHydraulic output is characterized by an Open S-tube impeller with a 392.4 mm actual diameter and a 44 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 30.4 m. The design features a 200 mm inlet and a 150 mm outlet with DIN flanges, supporting high-volume transfer through high-head wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron motor casing and pump housing with double mechanical SiC\/SiC shaft seals. Protection is provided by integrated PTO sensors, moisture switches, and leakage sensors for motor protection and monitoring in centralized stations. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 rated enclosure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen S-tube impeller with 392.4 mm diameter and 44 mm passage for managing solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural durability in networks.\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 supporting stable thermal control 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 stations.\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.
