Abstract
A simple graphical tool was developed, that finds optimal combination of pumps and their rotational speeds for all possible working points for the given set of pumps. The tool allows analyzing and optimizing non-identical parallel pump with different minimum and maximum frequencies. Characteristic and efficiency curves can be given in tabular format in addition to analytical functions of flow. Degradation of pumps’ efficiency at lower rotational speed is taken into account, as is motor and variable speed drive efficiencies at partial loads. The optimal solution provided by the tool was compared to actual measurements in a case study.
