Abstract

An electrical submersible well pump assembly has an inducer and diffuser for applying a positive pressure to the first pump stage. The pump assembly includes a centrifugal pump with a housing having a well fluid inlet and a number of pump stages. Each pump stage has an impeller and a diffuser. An inducer is mounted in the housing upstream of the impeller of the first pump stage. The inducer has a helical flight that is rotatable in unison with the pump. A diffuser is positioned between the inducer and the impeller of the first stage.
