This cast iron pump is built for permanent submerged service where untreated sewage and wastewater contain large solids. It ensures consistent hydraulic transfer in utility infrastructure with liquid temperatures from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eA slow-speed 28 kW 8-pole motor running at 726 rpm provides the power to achieve a maximum flow rate of 24900 L\/min and 13.1 m head. Drawing 54 Amps from a 415 V supply, stable motor operation is maintained during massive volume transfer. The system supports consistent pumping performance for high-capacity municipal collection networks.\u003c\/p\u003e\u003cp\u003ePumping performance is achieved using a 2-channel ductile iron impeller with a 421 mm actual diameter and a 145 mm free passage for managing untreated wastewater containing solids. The DN 300 outlet features DIN flange standards and a PN 10 rating to support high-volume displacement. This design focuses on reducing clogging risks while moving raw sewage through municipal grids.\u003c\/p\u003e\u003cp\u003eStructural integrity is provided by the EN-GJL-250 cast iron casing and double mechanical SIC\/SIC-CARBON shaft seals. Safety monitoring is provided by integrated moisture sensors and leakage detection to ensure motor protection in submerged conditions. The unit includes a 15-metre S1BN8-F power cable and is compatible with the Grundfos DN300 auto-coupling system (96782484).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2-Channel ductile iron impeller with a 421 mm diameter and 145 mm passage for handling solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural integrity in infrastructure stations.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SIC primary faces and SIC-CARBON secondary barrier protection.\u003c\/li\u003e\n\u003cli\u003eIntegrated moisture switch and leakage sensors for proactive motor protection and monitoring.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 20 metres with a PN 10 rated DN300 outlet.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 15-metre S1BN8-F power cable for reliable electrical connection in wet wells.\u003c\/li\u003e\n\u003cli\u003eSlow-speed 8-pole motor design optimized for high-volume wastewater and stormwater transfer.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN300 auto-coupling system (96782484) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
