This paper presents some phenomena concerning the stability problem of the basic flow direction observed within the CFD analyses of an unconventional radial pump stage (RPS). In order to preclude defining the flow direction as aboundary condition, a closed hydraulic system was modelled to investigate theoperating behaviour of the RPS and its energy characteristics. It was shownthat the basic flow direction through the RPS is determined by the level of hydraulic losses within the closed hydraulic system. Combining the closed and open hydraulic system calculations, all possible operating regimes of the analysed RPS are presented by means of 4-quadrant chart.
