Francis Turbine Runner and Generator Rotor


Francis turbines are the most common water turbine in use today.

They operate in a water head range of 10 to 300 meters and are primarily used for electrical power production. The power output generally ranges from 100KW to 750MW.

Normally, Medium size and larger Francis turbines are most often arranged with a vertical shaft, Small francis turbine always arranged with horizontal shaft, but it is not absolute.



Horizontal/vertical Francis turbine

Water head

 10m -- 300m.

Installation capacity

 0.1MW -- 20MW

Runner material

Stainless steel (0Cr13Ni4Mo)

Generator type

synchro generator

Auxiliary Equipment

Governor, Inlet Valve, unit side panel, excitation system


The Francis type turbine is mostly suitable for hydropower stations with medium or high head from 10m to 300m. They are in both vertical or horizontal shaft arrangement and could be vastly selected by the hydraulic power stations.

lts feature is that the water flow enters the runner inward in a radial direction , changes direction gradually and then passes out axially. Francis turbine is characterized by reliable operation, simple construction and high efficiency, etc. Hydoru manufacture Francis runner have a good efficiency and cavitation performance.

 Normally, we adopt the horizontal Francis with capacity below 5MW, runner diameter below 90cm. And the vertical Francis with capacity below 20MW.
