The most versatile water turbines around

The versatile Francis turbine is a medium-pressure turbine. Due to its method of operation, this water turbine is ideally suited for power plants with a low to medium head (5-300 m) and corresponding flow rates.



  • Versatile for up to 30 MW of electricity
  • Hydropower from 5-300 m head
  • Guaranteed hydraulic characteristics with highest efficiency
  • Compact turbine in the form of shaft or spiral turbines
  • Minimal to no wear of wear parts

Customized designs for greater cost efficiency

Depending on the height, Geppert offers them in the form of open-flume turbines or spiral turbines with vertical or horizontal shafts. The turbines are manufactured to the highest quality standards at the Geppert plant in Hall, Tirol, from where they are delivered to countries all over the world. The products undergo continuous development through model tests, which ensures the turbines maintain their hydraulic performance.

The spiral turbine is usually designed as a compact turbine with the impeller mounted on the generator shaft, which allows the size of the turbine room to be reduced to a minimum. This 2-bearing arrangement avoids the use of a coupling or other wear parts. In addition to the ecological advantage, this is also an economic plus as it keeps running costs to a minimum. Each Geppert Hydropower plant can be configured to client specifications, fully automated and remotely monitored on request. Each turbine is individually designed and built on the basis of the design data, net head and volumetric flow rate.

Geppert is able to manufacture Francis runners in various designs. This concerns, for example, the production of a one-piece, two-piece or three-piece Francis runner. The production of two- or three-piece Francis runner requires a lot of manual work. These are welded together by hand from several components, which allows us to respond flexibly to every customer request in order to be able to execute the best possible solution.
