Problems of energy efficiency of pumps and pumping systems

The total energy consumption of various types of pumps is significant and the energy saving potential in this area is also huge. The transition from consideration of the characteristics of a separate pump to the features of its operation with a drive, taking into account the operation in different modes in conditions of a specific hydraulic network, allows obtaining a much greater potential for reducing energy consumption, significantly increasing the efficiency and reliability of pumping equipment.
