Pump selection using dynamic priority numbers

A control system includes a processor with pump data for a parallel connected plurality of pumps in a database of an associated memory for implementing a dynamic priority number (DPN)-based pump selection algorithm for a method of pump selection for the plurality of pumps. The method includes calculating a DPN using pump data regarding a plurality of pump parameters for each of the plurality of pumps. The DPNs are dynamically updated when at least one of the pump parameters changes. The DPNs are used together with a current pump demand to dynamically select which of the pumps are to be turned on or off, and the dynamic selection is implemented. The DPNs can be calculated using a DPN equation.
