Product Overview
Municipal transfer stations requiring massive volume displacement for raw effluent rely on the high-torque performance of the Grundfos S2.145.300.280.8.62E.S.421.G.N.D.513. 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.
A 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.
Pumping 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.
Structural 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).
