Product Overview
Municipal utility stations requiring reliable wastewater transfer utilize the Grundfos S1.100.125.400.4.62M.S.345.G.N.D.513 for heavy-duty submerged service. This cast iron pump is built for permanent installation in municipal collection networks where untreated wastewater contains solids. It is designed to maintain hydraulic efficiency in infrastructure environments with liquid temperatures from 0°C to +40°C.
Performance is driven by a 41 kW 4-pole motor running at 1464 rpm with a rated current of 82 Amps on a three-phase 415 V supply. The pump achieves a maximum head of 48.1 m and a maximum flow of 8100 L/min. Stable motor operation is maintained during heavy-volume transfer cycles, providing the required hydraulic power for municipal sewage handling.
Wastewater is transferred through a 1-channel cast iron impeller with a 345 mm actual diameter and a 100 mm free passage for managing untreated wastewater containing solids. Featuring a DN 125 outlet connection with DIN flanges, this design facilitates high-efficiency wastewater transfer through municipal grids. The hydraulic setup reduces the risk of clogging while maintaining consistent discharge pressure.
Structural integrity is provided by the EN-GJL-250 cast iron casing and double mechanical shaft seals with SIC/SIC-CARBON faces. Protection monitoring is provided by integrated moisture sensors and thermal switches to ensure motor safety in submerged conditions. The unit includes a 15-metre H07RN-F power cable and is compatible with the Grundfos DN125 auto-coupling system (96782145).
