A method is proposed for selecting the best values for the geometrical and working parameters of a spiral impeller with constant pitch, which gives the maximal cavitation performance in pumps in which it is used either as a preliminary pumping facility (centrifugal pump) or the inlet section of an axidiagonal pump
