The target of this research is the derivation of evaluation method for variable speed centrifugal pumps in water supply systems. For this reason a great number of analyses have been realized for different pumps and regression equations have been derived. The trend of reduction of energy consumption has been determined, if the proportional pressure control is used in comparison with constant pressure control. It’s been found that the reduction of annual energy consumption can be achieved up to 35%, if the proportional pressure is applied and deviations from head value of duty point at zero flow rate declines up to 50%.
