Optimisation service for pumping systems Energy optimisation for pumping groups comprising multiple parallel centrifugal pumps equipped with variable-frequency drives
This service covers the management of pumping systems comprising multiple parallel centrifugal pumps. The ultimate goal, on the one hand, consists in evaluating the degree of energy and economic savings that can be reached in a given pumping group according to the features of the equipment installed and historic operating data. And, on the other, in generating an optimum operation algorithm which, once incorporated to the pumping group’s control system, determines the optimum number of pumps and their operating frequency as a function of operating conditions.
Benefits Energy savings Extended equipment service life Reduced risk of cavitation (less NPSH required)

Technical specifications Application: pumping groups with multiple identical or different parallel pumps equipped with variable-frequency drives. Data required: flow, height and electrical consumption (one or two variables could suffice as a function of each case). Necessary analysis: interaction with the control loop of the pumping group.
