Product Overview
Industrial effluent management relies on the Grundfos SL1.80.100.55.4.50B.C for permanent submerged installation in collection reservoirs and sumps. This cast iron model holds CE EN12050-1 approval and is designed for untreated wastewater transfer in heavy-duty utility sites. It is suitable for handling contaminated liquids in demanding processing environments.
A 5.5 kW 4-pole motor operating on a 3 x 415V supply with a rated current of 10.9 Amps powers the unit at 1463 rpm. It achieves a maximum head up to 19.1 m and a maximum flow up to 3414 L/min. The motor is designed for continuous S1 duty in untreated wastewater with a temperature range of 0°C to 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.
The S-tube impeller provides an 80 mm free passage for untreated wastewater containing solids while helping reduce the risk of clogging. The hydraulic design features a DN 100 inlet and a 4" (100 mm) outlet with DIN flange standards. This configuration supports consistent fluid discharge in industrial networks.
Construction includes an EN-GJL-250 cast iron pump housing and motor casing. Protection features a double SIC/SIC mechanical shaft seal and integrated PTC sensors for motor protection. Integrated moisture sensors are used for seal and motor monitoring, along with 10 metres of LYNIFLEX power cable and an IP68 enclosure rating. The pump is suitable for installation depths up to 7 metres.
