Abstract: The pumping systems energy efficiency improvement represents an important tool for energy savings and greenhouse gases (GHGs) emission mitigation. The paper presents some modern solutions for energy consumption minimization of the main types of pumps and pumping systems (energetic and thermal equipments, clear and waste water systems so.). Also, it is proposed an assessment and optimization method of the energy efficiency solutions, considering relevant and measurable economic and ecologic characteristics. The effects are compared with a references solution, based on an energy savings maximization function, with practical operation restrictions. The method highlights both the best rehabilitation solutions and operation optimization for existing installations and the optimal solutions for the new installations design.
