A pump includes a shaft that is rotatable about a central axis. An inducer is mounted on the shaft and has an inducer blade and inducer shroud attached at an outer end of the inducer blade. An impeller is mounted on the shaft downstream of the inducer and has an impeller blade and an impeller shroud attached at an outer end of the impeller blade. There is an axially-elongated annular seal element disposed at an axial end of the inducer shroud that provides sealing between the inducer shroud and the impeller shroud.
