Product Overview
Wastewater handled in large municipal complexes and sewage collection systems requires an efficient solution for effluent management like the SEV.80.80.40.4.50B. This submersible pump is intended for the pumping of contaminated liquids in collection pits where a stable pH between 4 and 10 and temperatures up to 40°C are maintained. The system is configured for reliable transfer in drainage stations, preventing structural damage from fluid accumulation. Its architectural build supports permanent dry or submerged installations prone to varying fluid ingress rates.
Powered by a 4 kW four-pole motor on a 415v three-phase supply, this model delivers 1500 L/Min flow and a maximum head of 17.1 m. The electrical configuration maintains a steady 9.6 Amps rated current at a synchronous speed of 1460 rpm for consistent torque. This performance profile ensures the rapid evacuation of wastewater through the 80 mm discharge port to protect critical infrastructure and pump stations. The system is designed for stable operation through a 15-metre Lyniflex power cable that supports integration into wastewater collection systems.
Hydraulic behavior is centered on a cast iron SuperVortex impeller designed for the passage of solids up to 80 mm in diameter. This configuration prevents internal clogging by allowing particles to pass through the pump housing without direct contact with the impeller vanes. By utilizing a vortex flow path, the unit minimizes internal friction and wear, extending the functional life of the rotating assembly during wastewater handling. The impeller setup is intended for grey water and effluent transfer in municipal and industrial wastewater handling.
Mechanical integrity is reinforced by a heavy-duty cast iron pump body and motor shell with an IP68 enclosure rating. Motor protection is anchored by a double mechanical shaft seal in an oil bath featuring a SiC/SiC primary seal for maximum abrasive resistance and a CER/CARNBR secondary seal. This unit includes a DN 80 inlet size for integration into standard wastewater infrastructure and treatment plant transfer duties. The architectural casting features a stable base for firm positioning in subsurface collection pits.
Features
- SuperVortex impeller configuration facilitates the passage of solids up to 80 mm without internal clogging.
- Heavy-duty cast iron housing and motor shell provide a durable foundation for dry and submerged site installations.
- Four-pole motor operating at 1460 rpm provides torque for processing wastewater containing dense organic materials.

Calculating peak drainage throughput, what maximum fluid volume passes through this casing?
Rated for intensive drainage cycles, Grundfos SEV.80.80.40.4.50B maintains a discharge of 1500 L/Min.
In municipal sewage lift stations, what peak dynamic lift does this heavy pump maintain?
Deep-well sewage extraction benefits from SEV.80.80.40.4.50B, which achieves a head of 17.1 m.
Providing motor torque, which electrical power parameters, operating voltage feed, and running current power this submerged pump?
Station electrical infrastructure powers SEV-80-80-40-4-50B with a 4 kW motor on a three-phase 415 V connection at 9.6 Amps.
Passing municipal effluent, how does the vortex hydraulic geometry allow raw wastewater solids to clear cleanly?
Solid waste clearance reaches 80 mm in SEV 80 80 40 4 50B, driven by its precision-cast SuperVortex channel.
When mounted on guide pipes, which guide rail mounting configuration supports submerged installation in collection sumps?
A self-sealing auto-coupling connection joins SEV/80/80/40/4/50B to station discharge pipework without manual bolt tightening.
