1. A method for improving energy efficiency of a pump system, wherein the pump system comprises one or more pumps, the method comprising:

  • measuring instantaneous power consumption of the pump system;

    measuring instantaneous fluid flow rate of the pump system;

    determining an instantaneous specific energy consumption (SEC) of the pump system based on the instantaneous power consumption of the pump system and the instantaneous fluid flow rate of the pump system; and

    adjusting speed of the one or more pumps in response to said determining;

    wherein said measuring instantaneous power consumption, said measuring instantaneous fluid flow rate, said determining and said adjusting are performed a plurality of times to seek a reduced value of the instantaneous SEC of the pump system.
