Product Overview
Subsurface structural protection in wastewater collection systems and municipal networks is provided by the cast iron housing of the SEV.80.80.22.4.50B. This submersible unit addresses requirements for the removal of contaminated liquids with a pH value between 4 and 10. The pump is intended for drainage stations and wastewater transfer duties where reliable solids passage and continuous operation are **required** for maintenance. The system maintains stable performance in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C.
Hydraulic capacity is provided by a 2.2 kW four-pole motor operating on a 415v three-phase supply with a rated current of 5.6 Amps. This assembly generates a maximum flow of 1398 L/Min and achieves a maximum head of 12.4 m to satisfy discharge requirements in municipal lift stations. The motor operates at 1445 rpm, ensuring consistent pressure behavior and circulation characteristics during the service cycle. Power is distributed through a 15-metre Lyniflex cable to support sub-surface wastewater handling and gravity drainage networks.
Internal fluid velocity paths utilize a SuperVortex impeller configuration to facilitate the passage of solids in suspension. This centrifugal design handles particles up to 80 mm in diameter, preventing internal clogging that could compromise volumetric efficiency over thousand of hours of operation. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to protect the rotating assembly during prolonged service. The impeller handles liquids containing organic materials to maintain operational flow behavior in wastewater collection pits.
Mechanical integrity is reinforced by a heavy-duty cast iron housing and motor shell with an IP68 enclosure rating for permanent dry or submerged installations. Motor protection is anchored by a double mechanical shaft seal in an oil bath featuring a SiC/SiC primary seal and CER/CARNBR secondary seal. This unit includes an integrated thermal sensor for operational monitoring and protection against electrical fluctuations. The architectural casting features a DN 80 inlet and DN 80 outlet for integration into standard wastewater infrastructure and treatment plants.

For heavy municipal lift vaults, what peak volumetric displacement is delivered?
Elevating raw municipal effluent, Grundfos SEV.80.80.22.4.50B achieves a peak volumetric flow of 1398 L/Min.
What vertical fluid lift is developed when operating this pump under heavy delivery load?
Hydraulic elevation capacity tops out at 12.4 m when operating SEV.80.80.22.4.50B.
From an electrical perspective, which motor kilowatt output, line voltage feed, and operational current draw support this pump?
Performance in SEV-80-80-22-4-50B is maintained via a 2.2 kW motor on a three-phase 415 V feed drawing 5.6 Amps.
In wastewater collection pits, how does the recessed runner profile maintain clear fluid transit across subterranean wet wells?
Volute passage clearances in SEV 80 80 22 4 50B measure 80 mm, allowing untreated sewage to exit through the SuperVortex corridor.
Docking onto wet well elbows, which auto-coupling arrangement facilitates secure submerged docking on guide rail pipes?
Heavy-duty auto-coupling duckfoot pedestals anchor SEV/80/80/22/4/50B at the pit base while dual guide pipes direct hoist travel.
