Also known as cross-flow turbines, they consist of a drum type rotor with stamped blades. A flow regulator profile controls and directs the flow of water to the turbine rotor. This type of turbine is used in hydraulic potentials with smaller falls and larger water volume, characteristic of flatter regions.
Pelton-type turbines consist of a rotor formed of cast shells with one or more jets. The jet of water from the injector, when hitting the shells, moves the rotor. This type of turbine is used in hydraulic operations with higher falls and lower water volume, a situation that usually occurs in mountainous regions.
