Kaplan turbines are reaction machines and are suitable for exploiting relatively low hydraulic heads and high flow rates.
The Kaplan turbine is a hydraulic propeller turbine with adjustable blades. It was invented in 1913 by the Austrian professor Viktor Kaplan.
The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient energy production in low-head applications that was not possible with Francis turbines.
Depending on the particular system, we can design and install Kaplan turbines of the following types:
The turbine is composed of:
