The results of numerical investigations of flow through axial thrust balance holes in impeller of low specific speed pump were presented. The results were compared with available empirical investigations. It is a lack of numerical analyses in foregoing literature on flow through rotating holes. The issue is important for designing rotodynamic pumps. There are difficulties in solving the problem of precisely computing the flow in balance holes analytically.
