Francis turbines


Thanks to continuous optimization over the years based on the latest hydrodynamic research, well over half the turbines manufactured by Voith Siemens Hydro Power Generation are of the Francis type.
Our Francis turbines, including the world’s largest and most powerful, are in service around the globe in numerous hydropower plants. What better testimony to our more than 130 years of water turbine know-how?

Characteristics:

Francis turbines are used primarily for medium heads and large flows. Their special hydraulic characteristics enable relatively high-speed compact units, right up to the highest power outputs.
Voith Siemens Hydro Power Generation also supplies cost-effective Francis units in standardized designs and packages for small hydro plants.
