Product Overview
High-volume transfer in civil infrastructure is the primary application for the Grundfos SL1.100.150.75.4.50B.C, a submersible wastewater pump intended for permanent installation. Holding CE EN12050-1 approval, this unit is built for municipal wet wells and basins prone to untreated wastewater containing large solids. It is developed for handling raw effluents in high-demand networks.
Operating on a 3 x 415V supply with a rated current of 14.4 Amps, this model features a 7.5 kW 4-pole motor operating at 1462 rpm. It achieves a maximum head up to 19.4 m and maximum flow up to 4998 L/min. The motor is designed for continuous S1 duty in untreated wastewater at temperatures between 0°C and 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 100 mm while helping reduce the risk of clogging. The hydraulic design features a DN 150 inlet and a 6" (150 mm) outlet with DIN flange standards. This configuration supports high-volume fluid transfer in municipal wastewater systems.
Construction features EN-GJL-250 cast iron for the pump housing and motor casing. Protection includes a double SIC/SIC mechanical shaft seal arrangement and integrated PTC thermal sensors for motor monitoring. Integrated moisture sensors are included for seal and motor monitoring, along with a 10-metre LYNIFLEX cable and IP68 enclosure rating. The pump is suitable for installation depths up to 7 metres.
FEATURES
- S-tube impeller with 100 mm free passage for processing large solids-laden wastewater without clogging.
- 7.5 kW 4-pole motor operating at 1462 rpm on a 3 x 415V three-phase supply with 14.4 Amps rated current.
- DN 150 inlet and 6" (150 mm) discharge connection for large-scale wastewater relocation.
- Double mechanical SIC/SIC shaft seals with an oil chamber for redundant moisture defence for the shaft.
- Integrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.
- Built-in thermal switches within the stator windings for automatic protection against electrical overheating.
- 10-metre rugged LYNIFLEX power cable and IP68 moisture protection for deep submerged operation.
- CE EN12050-1 certified for use in high-volume wastewater transfer and demanding relocation sites.

Can this pump clear unscreened raw sewage and fibrous waste?
Spherical solids and particulate up to 100 mm pass freely through the Grundfos SL1.100.150.75.4.50B.C, thanks to its debris-resistant runner.
What connection layout and port dimensions are featured on this unit?
Discharge pipework interfaces directly with the SL1.100.150.75.4.50B.C through a standard guide rail auto-coupling for quick field installation.
How much fluid can this pump evacuate during peak demand?
At full operating capacity, the SL1-100-150-75-4-50B-C moves up to 4998 L/Min to keep liquid levels controlled during peak inflow.
How many meters of dynamic lift does this pump provide?
Under rated operating head, the SL1 100 150 75 4 50B C can lift water to a maximum dynamic head of approximately 19.4 m through vertical risers.
How much electricity and current does this pump draw under load?
Running on 415 V three-phase power supplies, the SL1/100/150/75/4/50B/C is driven by a 7.5 kW motor rated at 14.4 Amps.
