Grundfos SEV.80.80.15.4.50B Cast Iron 4-Pole Submersible Pump for Lift Stations with SuperVortex Impeller

Managing the operational load of municipal and industrial drainage systems requires a specialized hydraulic solution like the SEV.80.80.15.4.50B. This unit is intended for the handling of grey water and contaminated liquids with a pH value between 4 and 10 in collection pits. This submersible pump manages these requirements by providing reliable removal of wastewater containing organic solids. The system maintains stable performance in both submerged and dry installations where consistent water transfer is necessary for facility maintenance and infrastructure protection.

Hydraulic performance is driven by a 1.5 kW four-pole motor on a 415v three-phase supply, generating a maximum flow of 1200 L/Min. This model achieves a maximum total head of 9.8 m, making it suitable for low-head discharge in drainage stations and wastewater collection pits. Operating with a rated current of 4 Amps at 1435 rpm, the four-pole motor maintains consistent torque for processing fluids with temperatures up to 40°C. Rapid evacuation is achieved through the DN 80 discharge port using a 15-metre power cable for secure electrical connection.

Internal centrifugal design utilizes a SuperVortex impeller to facilitate the passage of solids in suspension without internal clogging. This configuration handles particles up to 80 mm in diameter, maintaining volumetric efficiency throughout prolonged service cycles in municipal and industrial environments. By utilizing a vortex flow path, the unit minimizes internal vibration and friction to protect the rotating assembly during grey water handling. The impeller configuration is intended for liquids containing organic materials in municipal wastewater handling.

Mechanical stability is achieved through a heavy-duty cast iron housing and motor shell with an IP68 protection rating for permanent immersion. The motor is shielded by a double mechanical shaft seal in an oil bath, utilizing a SiC/SiC primary seal for abrasive resistance and a CER/CARNBR secondary seal. This unit features an internal thermal sensor for motor protection and monitoring during continuous operation. The assembly includes a DN 80 inlet for integration into wastewater collection systems and infrastructure with a 20 m installation depth.
