Product Overview
Industrial effluent transfer and municipal wastewater collection systems are the focus of the Grundfos SL1.50.80.40.2.50B.C. This cast iron submersible pump holds CE EN12050-2 approval and is built for treatment plants and centralized sumps. It is suitable for conveying untreated wastewater through discharge piping in civil environments.
This model features a 4 kW 2-pole motor running at 2930 rpm. Operating on a 3 x 415V supply with a rated current of 8.2 Amps, it provides a maximum head up to 26 m and a maximum flow up to 1164 L/min. The motor is rated 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 is designed for untreated wastewater containing solids up to 50 mm while helping reduce the risk of clogging. The unit includes a DN 65 inlet and a DN 80 (3") outlet with DIN flanges. This configuration supports the transfer of untreated effluents in industrial transfer sequences.
Built with an EN-GJL-250 cast iron pump housing and motor casing, the unit features a double SIC/SIC mechanical shaft seal arrangement. Integrated moisture sensors are used for seal and motor monitoring. Protection includes PTC sensors, winding-embedded thermal switches, 10 metres of LYNIFLEX power cable, and an IP68 enclosure rating. The pump is suitable for installation depths up to 7 metres.
FEATURES
- S-tube impeller with 50 mm free passage for reliable transit of solids-laden water in industrial applications.
- 4 kW 2-pole motor operating at 2930 rpm on a 3 x 415V three-phase supply with 8.2 Amps rated current.
- High-head performance up to 26 m for high-pressure wastewater relocation in treatment plants and sumps.
- DN 65 inlet and DN 80 (3") discharge connection with DIN flange standards for industrial piping infrastructure.
- Double mechanical SIC/SIC shaft seals with an oil chamber for redundant moisture defence against fluid infiltration.
- Integrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.
- Class H stator insulation and IP68 protection classification for safe, deep-well submerged operation.
- 10-metre heavy-duty LYNIFLEX power cable for flexible installation in deep wastewater sumps and wet wells.
