Product Overview
Wastewater collection pits and municipal networks require a specialized hydraulic solution capable of processing grey water with a pH between 4 and 10. The SEV.80.100.40.2.50B addresses these environmental demands by providing removal of contaminated liquids containing organic solids. This unit is intended for drainage stations and wastewater transfer duties where reliable solids passage and continuous operation are required. The system maintains stable performance in dry or submerged installations prone to varying fluid ingress and temperatures between 0 and 40°C.
Hydraulic behavior is driven by a 4 kW motor operating on a 415v three-phase supply with a rated current of 8.2 Amps. This assembly generates a maximum flow of 1332 L/Min and reaches a maximum head of 21.6 m to satisfy discharge requirements in municipal lift stations and pressurized sewer mains. The model operates at a synchronous speed of 2925 rpm, ensuring consistent pressure behavior and hydraulic stability during the service cycle. Power is distributed through a 15-metre Lyniflex cable to support sub-surface infrastructure and treatment plant transfer.
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 integrity is reinforced by a cast iron pump body and motor shell with an IP68 enclosure rating for protection against liquid ingress. The motor is shielded by a double mechanical shaft seal featuring a SiC/SiC primary 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 casting includes a DN 80 inlet and a DN 100 outlet for integration into standard wastewater infrastructure and pump stations.
Features
- SuperVortex impeller design handles solids up to 80 mm without risk of internal blockages during wastewater transfer.
- Cast iron housing and motor shell provide a stable and rigid foundation for dry or submerged pit installations.
- Maximum head performance of 21.6 m allows for wastewater discharge in municipal and drainage applications.
- Double mechanical shaft seal in an oil bath with silicon carbide faces ensures protection for the 4 kW motor.
- DN 80 inlet and DN 100 outlet connections are sized for wastewater transfer through standard plumbing networks.
- IP68 enclosure rating ensures the motor remains protected during permanent immersion in contaminated liquids.
- Lyniflex 15-metre power cable provides a secure, chemical-resistant electrical connection for wastewater handling service.
