This paper deals with CFD incorporation in a process of designing inducer with variable pitch. The introductory part is devoted to the theory of centrifugal pumps, cavitation and inducer itself followed by a description of the mathematical models of turbulence, multiphase fluid and cavitation. The main part of this paper consists of CFD evaluation, first, of inducer itself, later in application with centrifugal pump with regards to cavitation properties with and without the aplication of inducer, for interest, the comparison with different type of inducer, with constatnt pitch, is also included. At the end of this paper the advantages and some disadvantages are given for CFD based design of the hydrodynamic machines.
