Grundfos SEV.80.80.265.2.52H.N.51D.A (99774878)
Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage. The pump is designed for intermittent and continous operation. The cooling jacket ensures that the pump can operate submerged or dry installed. The efficient SuperVortex impeller provides passage of long fibres and solids up to 80 mm and is suitable for wastewater with a dry matter content of up to 5 %. The pump comes with a high efficient Grundfos motor built on IE3 mo

Applications
- Commercial wastewater — Commercial buildings have vastly different requirements for wastewater transfer. Grundfos supplies wastewater pumps and lift station pumps ensure superior reliability and safety, as well as high efficiency.
- Flood control — Grundfos supplies complete flood control systems to protect urban and rural areas, infrastructure and large cities from flooding. Our innovative solutions meet the high-flow and low-head requirements at the flood pumping station or pump gate.
- Industrial wastewater treatment & reuse — Grundfos offers solutions that add value to every step of wastewater treatment required for safe and compliant discharge or for water reuse in your facility. You get the most efficient treatment combined with intelligent measurement and control for maximum safety and minimum downtime.
- Wastewater transport — When continuously transporting wastewater, you need reliable and optimised solutions for wastewater pumping stations and networks. Better system design, for example by using CFD simulations, tackles hydraulic issues in advance, reduces downtime and minimises risk.
- Wastewater treatment — Treating wastewater is about maintaining optimal and effective processes at mechanical, biological and chemical treatment stages. A full-line supplier, Grundfos ensures that hydraulic stability is maintained and capacity not exceeded for all processes.
category
- Submersible wastewater pumpsGrundfos submersible wastewater pumps are designed as sealed units combining a pump and integrated motor that can operate below the surface of wastewater. Submersible wastewater pumps are perfect in permanent installations for efficient removal of wastewater from a property whether from washing machines, sinks and showers or drainage from the garden.
