The paper considers the influence of the size of the front end gap between the impeller and the housing on the energy performance of the pump, selects the parameters, compiles a mathematical model used in hydrodynamic modeling, presents the results of the study, draws conclusions about the influence of the size of the front gap between impeller and housing on efficiency and pump head. A comparison is made of the dimensionless pump characteristics obtained by the methods of hydrodynamic modeling with experimental dependences.
