The aim of the thesis was to propose a pump impeller with higher effectiveness and verify the proposal with the calculation using programs Gambit and Fluent. Three designed impellers were afterwards made using 3D printer and its characteristics were measured in a hydraulic laboratory in Kaplan Department of hydraulic machines. The proposal of a so called wideband impeller of the centrifugal pump was made with chaotic ordering of blade cascades, in one impeller occur blades with various input and output angles and different shapes of blades but all blades have got similar shape in a meridian sectional view of impeller. The thesis was divided into three parts. In the first part, a conforming transformation was theoretically described which was in the thesis used for the shape proposal of impeller blades. In the second part of the thesis final proposals and calculations of pump impellers were made. The third part of the thesis focused on the processing and evaluation of experimental measurement in the hydraulic laboratory and finally the results of the thesis were summarized in the conclusion.
