Product Overview
Effluent transfer sumps in municipal grids utilize the Grundfos S1.100.125.500.4.62M.S.367.G.N.D.513 for centralized submerged installations and reliable sewage handling. This cast iron pump manages untreated wastewater and sewage containing solids in permanent stations. The unit is engineered for service in infrastructure environments with liquid temperatures from 0°C to +40°C.
The pump achieves a maximum head of 55 m and a maximum flow up to 8100 L/min while powered by a 50 kW 4-pole motor. Drawing 98 Amps on a 415 V supply, stable motor operation is maintained during high-capacity transfer. A Y/D starting method provides consistent pumping performance for large-scale wastewater infrastructure networks.
A 1-channel impeller provides the hydraulic force, featuring a 367 mm actual diameter and a 100 mm free passage for handling sewage containing solids. The DN 125 outlet incorporates DIN flanges and a PN 10 rating to support high-efficiency transfer. This configuration focuses on maintaining consistent discharge pressure while reducing clogging risks in municipal collection systems.
Structural durability is ensured by the EN-GJL-250 cast iron motor casing and pump housing protected by double mechanical SIC shaft seals. Protection is managed by integrated moisture sensors and leakage detection for proactive motor protection and monitoring. The unit is supplied with a 15-metre H07RN-F power cable and is compatible with the Grundfos DN125 auto-coupling system (96782145).
