Product Overview
Industrial sewage handling and municipal collection requiring centralized submerged installations rely on the S1.80.125.500.4.62H.S.398.G.N.D.513 for consistent performance. This cast iron pump manages untreated wastewater and contaminated media containing solids, ensuring reliable high-pressure wastewater transfer. The unit is intended for permanent service in infrastructure with liquid temperatures from 0°C to +40°C.
Driven by a 50 kW 4-pole motor at 1470 rpm, the pump achieves a maximum head of 67.1 m and a maximum flow of 6000 L/min. Operating on a three-phase 415 V supply with 98 Amps, stable motor operation is maintained during high-capacity transfer. A Y/D starting method provides reliable pumping performance for high-pressure discharge requirements.
A 1-channel impeller provides the hydraulic force, featuring a 398 mm actual diameter and an 80 mm free passage for handling solids. The DN 125 outlet incorporates DIN flanges and a PN 10 pressure rating to support high-efficiency wastewater transfer. This design is optimized for municipal collection and transfer applications where clogging prevention is a critical operational priority.
Structural durability is provided by the EN-GJL-250 cast iron casing and double SIC/SIC-CARBON mechanical shaft seals. Safety is monitored by integrated moisture sensors and leakage detection to ensure motor protection in submerged environments. The unit includes a 15-metre H07RN-F power cable and is compatible with the Grundfos DN125 auto-coupling system (96782145).
