Product Overview
Industrial transfer and deep sumps are the focus of the Grundfos SL1.80.100.30.4.50B.C, a submersible wastewater pump certified under CE EN12050-1. This cast iron model is intended for handling untreated wastewater containing large solids in permanent submerged installations. It is suitable for pumping applications requiring high-flow drainage and transfer.
Operating on a 3 x 415V supply with a rated current of 6.9 Amps, this model features a 3 kW 4-pole motor running at 1453 rpm. It delivers a maximum flow up to 2736 L/min and maximum head up to 12.7 m. The unit is rated for continuous S1 duty in untreated wastewater between 0°C and 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. Hydraulic connections include a DN 100 inlet and a DN 100 (4") outlet with DIN flanges. This single-vane configuration supports the transfer of raw effluents in industrial pumping systems.
Construction consists of an EN-GJL-250 cast iron pump housing and motor casing. Protection includes a double mechanical SIC/SIC shaft seal system and integrated moisture sensors for seal and motor monitoring. Motor safety is provided by thermal switches in the windings, a 10-metre 07RN8-F 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 handling solids-laden wastewater without clogging in industrial transfer.
- 3 kW 4-pole motor operating at 1453 rpm on a 3 x 415V three-phase supply with 6.9 Amps rated current.
- DN 100 inlet and DN 100 (4") discharge connection for efficient high-volume fluid trajectories in deep sumps.
- Double mechanical SIC/SIC seals in an oil chamber providing a redundant moisture barrier for the shaft.
- Integrated moisture sensors for monitoring of internal mechanical components during deep submersion.
- Built-in thermal switches within the motor winding for automatic electrical safety and heat regulation.
- 10-metre heavy-duty 07RN8-F power cable and IP68 enclosure for continuous operation in submerged basins.
- CE EN12050-1 certified for use in industrial transfer stations and deep sump wastewater collection.

Wet well guide rails connect cleanly to Grundfos SL1.80.100.30.4.50B.C via standard auto-coupling brackets that support rapid hoist lifting.
Within wastewater lift stations, what maximum fluid volume is displaced per minute across regional headers?
Regional transfer headers receive a maximum fluid volume of 2736 L/Min from SL1.80.100.30.4.50B.C.
Within regional wastewater collection vaults, what peak dynamic elevation is developed during heavy sewage transfer?
Regional collection vaults operate with SL1-80-100-30-4-50B-C developing a peak dynamic elevation of 12.7 m.
What are the motor kilowatt capacity, line voltage, and full-load current rating for this assembly?
Assembly ratings for SL1 80 100 30 4 50B C specify a 3 kW motor connected to a three-phase 415 V power feed drawing 6.9 Amps.
What internal passage dimension allows municipal solid waste to clear this heavy discharge casing?
Municipal solid waste up to 80 mm clears the heavy discharge casing of SL1/80/100/30/4/50B/C without impedance.
