Product Overview
Structural foundation in municipal wastewater systems is provided by the heavy-duty cast iron housing and motor shell of the SEV.80.80.75.2.50B. This submersible pump addresses requirements for the removal of contaminated grey water with a pH value between 4 and 10 and temperatures up to 40°C. This unit is intended for sewage collection systems and municipal networks where reliable solids passage and continuous operation are necessary for maintenance. The system maintains stable performance in both submerged and dry installation environments prone to varying fluid ingress.
Hydraulic capacity is provided by a 7.5 kW motor operating on a 415v three-phase supply with a rated current of 15 Amps. This model achieves a maximum flow of 1500 L/Min and reaches a maximum head of 34.3 m to overcome elevation requirements in pressurized sewer mains. The motor operates at 2940 rpm, maintaining torque and circulation characteristics throughout the service cycle in treatment plant transfer duties. Electrical connection is established via a 15-metre Lyniflex power cable, facilitating distribution for sub-surface wastewater handling and pump stations.
Internal centrifugal design utilizes a SuperVortex impeller configuration to facilitate the passage of solids up to 80 mm in diameter. This configuration handles sewage and wastewater in suspension, maintaining volumetric throughput and preventing the internal clogging that could compromise the rotating assembly. By creating a vortex flow within the pump housing, the design reduces internal wear and vibration for the rotating assembly during prolonged discharge. The hydraulic setup is intended for the movement of contaminated liquids through drainage stations and municipal lift stations.
Mechanical stability is achieved through an IP68 enclosure rating and a double mechanical shaft seal arrangement in an oil bath. The primary SiC/SiC seal and secondary CER/CARNBR seal protect the electrical heart from liquid ingress in submerged conditions. This unit includes moisture and water-in-oil sensors for early fault detection and protection against overheating. The casting includes a DN 80 inlet and a DN 80 outlet, ensuring structural integrity for permanent wastewater infrastructure and treatment plant transfer duties.
