Product Overview
Municipal wastewater networks rely on the Grundfos SL1.80.100.40.4.50B.C for handling raw effluents in wet wells and basins. Holding CE EN12050-1 approval, this cast iron submersible pump is built for permanent installation and handles untreated wastewater containing large solids in civil infrastructure.
The unit features a 4 kW 4-pole motor running at 1464 rpm. Operating on a 3 x 415V supply with a rated current of 9.6 Amps, it reaches a maximum flow up to 3066 L/min and maximum head up to 15.7 m. The motor is designed for continuous S1 submerged service in liquids between 0°C and 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.
Handling of untreated wastewater containing solids is managed by an S-tube impeller providing an 80 mm free passage while helping reduce the risk of clogging. Hydraulic design features include a DN 100 inlet and a DN 100 (4") outlet with DIN flange standards. This configuration supports the pumping of raw effluents through municipal discharge systems.
Construction includes an EN-GJL-250 cast iron pump housing and motor casing with double SIC/SIC mechanical seals. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Protection also includes 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 80 mm free passage for reliable transit of solids-laden wastewater in municipal networks.
- 4 kW 4-pole motor operating at 1464 rpm on a 3 x 415V three-phase supply with 9.6 Amps rated current.
- DN 100 inlet and DN 100 (4") discharge connection for efficient fluid trajectories in municipal networks.
- Double mechanical SIC/SIC shaft seals with an oil chamber for redundant moisture defence for the motor.
- 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 municipal wastewater networks and collection systems.

In deep collection basins, what peak volumetric throughput is maintained during heavy community usage?
Community peak usage hours see Grundfos SL1.80.100.40.4.50B.C maintain an operational throughput of 3066 L/Min.
In deep municipal effluent collection basins, what maximum discharge head does this heavy submersible unit attain?
Effluent collection basins deploy SL1.80.100.40.4.50B.C to attain an operational discharge head of 15.7 m.
Which electrical power draw, operating line voltage, and running current support this pump?
Supporting this pump, SL1-80-100-40-4-50B-C utilizes a 4 kW motor that connects to a three-phase 415 V line at 9.6 Amps.
How does the S-tube geometry sustain hydraulic flow without snagging heavy sanitary solids?
Hydraulic flow is sustained in SL1 80 100 40 4 50B C without snagging heavy sanitary solids through a wide 80 mm S-tube path.
What mounting system establishes a rigid discharge seal in municipal lift stations?
A rigid discharge seal in municipal lift stations is established by SL1/80/100/40/4/50B/C docking firmly onto auto-coupling pedestals.
