This type of turbine is used in low pressure plants that use large quantities of water with heads less than 40 meters.
Kaplan Turbines are impeller-turbines, where the runner turns in the water flow like a ship´s propeller. Runner blades and wicket gate are designed adjustable, to ensure an adaption to an unsteady water level and a changing head. These turbines are mostly used in run-of-river power stations.
