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.
- 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.
