 abstract={The article presents criterion of evaluating energy consumption of water pumping. The lower slope of pump efficiency characteristic curve was plotted for the case of: constant gain of rotational speed and variable gain of rotational speed. The unified form of the lower slope of pump efficiency characteristic curve was defined for variable head. The right-side coefficient of pump efficiency correction was defined.},
