This master’s thesis deals with changing the geometry of the output section of the impeller of the radial centrifugal pumps and its influence on the characteristics of the pump. In engineering practice for these radial centrifugal pumps it is possible to change the parameters based on the requirements. This adaptation of parameters is called impeller trimming. Impeller trimming means the reduction of the impeller diameter thereby decreasing the flow, head and efficiency. Existing equations for calculating the changes in the characteristics of the impeller trimming are inaccurate. In this thesis is describes a possible method of putting for the recalculation characteristics of a pump based on the impeller diameter on the available characteristics of pumps.
