This cast iron unit is intended for municipal and industrial wastewater applications where raw sewage containing solids must be moved reliably. It is engineered for service in infrastructure environments where liquid temperatures range from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum flow of 12300 L\/min and a maximum head of 46 m using a 36 kW 4-pole motor. Drawing 71 Amps on a three-phase 415 V supply, the unit incorporates an internal cooling jacket for thermal management. This integrated system provides reliable temperature control for high-capacity pumping in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eDynamics are controlled by an Open S-tube impeller with a 381.2 mm actual diameter and a 44 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 29.26 m. Featuring a 200 mm inlet and a 150 mm outlet, the hydraulic design supports high-volume transfer while helping to reduce the risk of clogging in discharge systems.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by the EN-GJL-250 cast iron casing and a double mechanical SiC\/SiC shaft seal. Protection features include integrated PTO sensors, moisture switches, and leakage sensors for proactive motor protection and monitoring in municipal collection systems. The unit includes 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 381.2 mm diameter and 44 mm passage for managing raw effluents.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for durability in permanent infrastructure.\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 enabling reliable temperature control in wet or dry installations.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10-metre S1BC4N8-F EMC power cable for reliable electrical connection in wet wells.\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.
