Product Overview
Wastewater transfer in municipal infrastructure requiring higher discharge pressure is the specialty of the Grundfos S1.80.125.400.4.62H.S.374.G.N.D.513. This cast iron pump is built for permanent submerged service in collection networks where raw sewage and untreated wastewater contain solids. It ensures consistent hydraulic transfer in utility environments with liquid temperatures from 0°C to +40°C.
A 41 kW 4-pole motor running at 1464 rpm provides the power to achieve a maximum flow of 6600 L/min and 57.5 m head. Drawing 82 Amps from a 415 V supply, stable motor operation is maintained during heavy-volume transfer cycles. The system supports consistent discharge pressure for high-lift requirements in wastewater infrastructure.
The hydraulic system uses a 1-channel cast iron impeller with a 374 mm actual diameter and an 80 mm free passage for managing untreated wastewater. Featuring a DN 125 outlet with DIN flanges, the design supports efficient wastewater transfer through high-head discharge systems. This setup helps prevent clogging while maintaining the hydraulic efficiency required for municipal grid systems.
Structural integrity is provided by an EN-GJL-250 cast iron motor casing and pump housing with a double mechanical shaft seal arrangement. Protection monitoring is managed by integrated moisture sensors and thermal switches to ensure motor safety in submerged conditions. The unit is supplied with a 15-metre H07RN-F power cable and is compatible with the Grundfos DN125 auto-coupling system (96782145).
