Product Overview
Municipal wastewater collection systems rely on the Grundfos SL1.80.80.40.4.50B.C for permanent submerged installation in lift stations. This cast iron pump holds CE EN12050-1 approval and is used for pumping untreated wastewater containing large solids. It is designed for handling raw effluents in civil utility networks.
The pump is powered by a 4 kW 4-pole motor operating at 1464 rpm on a 3 x 415V supply with a rated current of 9.6 Amps. It achieves a maximum head up to 16 m and maximum flow up to 2952 L/min. The unit is rated for continuous S1 submerged 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 is designed for untreated wastewater containing solids up to 80 mm while helping reduce the risk of clogging. Hydraulic connection sizes include a DN 100 inlet and a DN 80 (3") outlet with DIN flange standards. This single-vane design facilitates the conveying of untreated effluents through discharge piping.
Construction features an EN-GJL-250 cast iron pump housing and motor casing with double SIC/SIC mechanical shaft seals. Integrated PTC sensors and moisture sensors are used for seal and motor monitoring. Stator protection is provided by thermal switches in the windings, a 10-metre 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 processing contaminated fluids without clogging 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 80 (3") discharge connection for high-volume extraction in municipal wet wells.
- Double mechanical SIC/SIC shaft seals in an oil chamber providing a redundant moisture barrier for the shaft.
- Integrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.
- Built-in water-in-oil sensor providing early warning of potential fluid ingress into the internal oil chamber.
- 10-metre heavy-duty LYNIFLEX power cable and IP68 rated enclosure for deep submerged service in lift stations.
- CE EN12050-1 certified for use in municipal lift stations and centralized wastewater relocation sites.

What mounting base hardware facilitates guide rail positioning in municipal collection vaults?
Municipal collection vaults deploy Grundfos SL1.80.80.40.4.50B.C on guide rail auto-coupling bases that align the discharge port automatically.
In metropolitan collection chambers, what maximum volumetric flow does this heavy submersible unit discharge?
Metropolitan collection chambers deploy SL1.80.80.40.4.50B.C to discharge a peak volumetric flow of 2952 L/Min.
In municipal collection pits, what maximum hydraulic head is developed during high-volume drainage?
High-volume drainage in collection pits sees SL1-80-80-40-4-50B-C develop a maximum hydraulic head of 16 m.
Which motor output rating, supply line voltage, and operational current draw support this unit?
Supporting steady pumping, SL1 80 80 40 4 50B C incorporates a 4 kW motor fed by a three-phase 415 V supply drawing 9.6 Amps.
How does the contoured S-tube runner allow heavy solids to traverse the hydraulic chamber freely?
Heavy wastewater solids traverse the hydraulic chamber of SL1/80/80/40/4/50B/C freely via a contoured S-tube channel measuring 80 mm.
