Product Overview
Intended for permanent submerged installation, the Grundfos SL1.50.80.30.2.50B.C is designed to maintain wastewater levels and prevent overflows in civil basins. It holds CE EN12050-2 approval and is suitable for collection stations and municipal utility sites. The pump is engineered for handling untreated wastewater in submerged applications.
The pump is powered by a 3 kW 2-pole motor operating at 2909 rpm on a 3 x 415V supply with a rated current of 6.4 Amps. It achieves a maximum head up to 21.6 m and a maximum flow up to 1164 L/min. This model is rated for continuous S1 duty in untreated wastewater containing solids at temperatures up 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 is equipped with a DN 65 inlet and a DN 80 (3") outlet connection. This single-vane hydraulic design supports the discharge of raw effluents in municipal collection networks.
Construction features an EN-GJL-250 cast iron pump housing and motor casing. Shaft sealing is provided by a double mechanical SIC/SIC arrangement with integrated moisture sensors. The unit includes thermal switches in the windings, Class H insulation, a 10-metre 07RN8-F power cable, and an IP68 rated enclosure. The pump is suitable for installation depths up to 7 metres.
FEATURES
- S-tube impeller with 50 mm free passage for processing wastewater containing solids in collection networks.
- 3 kW 2-pole motor operating at 2909 rpm on a 3 x 415V three-phase supply with 6.4 Amps rated current.
- High-head performance up to 21.6 m for efficient wastewater relocation in municipal collection systems.
- DN 65 inlet and DN 80 (3") discharge connection with DIN flange standards for standard infrastructure piping.
- Double mechanical SIC/SIC shaft seals in an oil chamber providing redundant moisture defence for the motor.
- Winding-integrated thermal switches for automatic electrical safety and protection against overheating.
- Integrated moisture sensors for monitoring of seal integrity in deep wet well installations.
- 10-metre 07RN8-F power cable and IP68 enclosure for continuous submerged service in collection systems.

Which auto-coupling mounting base connects this pump unit to permanent discharge piping?
Permanent discharge piping interfaces cleanly with Grundfos SL1.50.80.30.2.50B.C via a dedicated auto-coupling mounting base for submersible sumps.
For regional sewage collection networks, what peak volumetric flow throughput is maintained per minute?
Across regional sewage networks, SL1.50.80.30.2.50B.C sustains an operational throughput reaching 1164 L/Min.
For demanding wastewater collection networks, what maximum hydraulic lift is developed during peak pumping?
Demanding collection networks rely on SL1-50-80-30-2-50B-C to develop a maximum hydraulic lift of 21.6 m.
What electrical power capacity, operating line voltage, and full-load current run this motor?
The motor in SL1 50 80 30 2 50B C produces a power capacity of 3 kW when connected to a three-phase 415 V grid line at 6.4 Amps.
How does the closed S-tube design facilitate smooth solids movement through municipal discharge lines?
Smooth solids movement is facilitated in SL1/50/80/30/2/50B/C by its closed S-tube runner, providing a generous 50 mm spherical clearance.
