In the field of hydropower, which is one of the sources of renewable energy, there are many places where water pressure of 2-5 meters can be created in water sources. However, hydraulic turbines operating on such sources are not widely used due to insufficient efficiency. This paper describes a counter-rotor hydraulic unit developed by installing an additional active impeller to a reaction hydraulic turbine based on a Segner wheel. Based on experimental results and theoretical analysis, the energy efficiency of a counter-rotor hydraulic unit was studied. As a result of research, it was found that the efficiency of a counter-rotor hydraulic unit varies between 87.2-93.5% at a water pressure of 2-5 meters.
