Grundfos SEG grinder pumps are non-self-priming, single-stage, centrifugal pumps with horizontal discharge port, specifically designed for pumping wastewater containing discharge from toilets. The pump is equipped with a grinder system that grinds destructible solids into small pieces to lead them through pipes with a relatively small diameter. SEG grinder pumps are ideal for use in sparsely populated areas, where gravity sewage systems are not available. Examples include villages, farm are

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.
- Domestic wastewater — With a series of optimised drainage pump systems, lifting stations and sump pumps, you can gain full control of domestic wastewater.
- 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.
- 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.
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.
