Francis turbine：

The Francis turbine is a type of water turbine that was developed by James B. Francis. It is an inward flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today.

The Francis type turbines are mostly suitable for hydro-power stations with medium or high head. The Francis type turbines manufactured by us are compact in structure, reasonable in design, convenient in operation and maintenance and excellent in efficiency. They are in both vertical and horizontal shaft arrangement and can be vastly selected by the hydraulic power stations. With many years of our own experience and absorbing advanced technology from domestic and abroad sources, and in meeting ever growing requirements of stations for various hydraulic power resources.
