This cast iron model is intended for municipal and industrial wastewater applications, specifically managing raw sewage containing solids. It maintains operational safety in infrastructure environments with liquid temperatures ranging from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe unit achieves a maximum flow rate of 15720 L\/min and a maximum head of 32 m using a 32 kW 4-pole motor. Drawing 65.5 Amps on a 415 V supply, the pump utilizes an internal cooling jacket for thermal safety. This integrated cooling allows for reliable operation during high-capacity transfer cycles in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eHydraulic handling is characterized by an Open S-tube impeller with a 334.5 mm diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 17.17 m. Equipped with dual 200 mm inlet and outlet connections, the design supports high-volume transfer while reducing clogging risks in municipal collection systems.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by an EN-GJL-250 cast iron motor casing and pump housing protected by double SiC\/SiC mechanical shaft seals. Protection is provided by integrated PTO sensors, moisture switches, and leakage sensors for comprehensive motor health monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure suitable for depths up 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 334.5 mm diameter and 71 mm passage for managing untreated solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron 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 for thermal management in both submerged and dry pit environments.\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 9 bar operating pressure.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN200 auto-coupling system (96641489) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
