The paper presents the results of an experimental investigation on the three-dimensional relative flow at the exit of the backward bladed centrifugal impeller of the high pressure stage of a two stage biregulating pump-turbine model, operating at the pump nominal point. Mean velocity, Reynolds stress tensor and total pressure of the relative flow have been measured with stationary hot wire probes and fast response miniature pressure transducers, by means of a
