Grundfos SEV.80.100.92.2.50B Cast Iron 2-Pole Submersible Pump for Pump Stations with SuperVortex Impeller

Wastewater collection systems and municipal networks require the removal of contaminated grey water with a pH value between 4 and 10. The SEV.80.100.92.2.50B addresses these requirements by providing a solution for high-volume wastewater transfer and effluent management. This unit is intended for drainage stations and treatment plant duties where reliable solids passage and continuous operation are necessary for maintenance. The system maintains stable performance in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C.

Hydraulic behavior is driven by a 9.2 kW motor operating on a 415v three-phase supply with a rated current of 17.3 Amps. This assembly generates a maximum flow of 1998 L/Min and achieves a maximum head of 35.2 m for discharge in pressurized sewer mains and pump stations. The model operates at a synchronous speed of 2935 rpm, ensuring consistent pressure behavior and hydraulic stability during the service cycle. Power is distributed through a 15-metre Lyniflex cable to support infrastructure in municipal wastewater networks and lift stations.

Internal fluid velocity paths utilize a SuperVortex centrifugal impeller designed for the passage of solids up to 80 mm in diameter. This configuration facilitates the movement of particles in suspension, preventing internal clogging that could compromise volumetric efficiency over long-term service. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to protect the rotating assembly during grey water handling. The impeller configuration is intended for liquids containing organic materials in municipal and industrial wastewater handling.

Mechanical construction features a cast iron pump housing and motor shell with an IP68 enclosure rating for protection against liquid ingress. The motor is shielded by a SiC/SiC primary shaft seal and CER/CARNBR secondary seal in an oil bath for insulation and durability. This unit includes an internal thermal sensor for motor monitoring and protection in submerged conditions. The architectural casting includes a DN 80 inlet and DN 100 outlet connection for integration into standard wastewater infrastructure and treatment plant transfer.
