Abstract
It is shown by results of a number of numerical calculations that a pump, optimized with respect to efficiency, does not, in the general case, have a maximum in efficiency at the rated point p=p_n, Q=Q_n of the pQ plane. Conventionally we call a pump for which η = η_max in the m-dimensional space of variable parameters (independent variables) ± î&u5Cé¶b>α₂,... ,α_m for a given p = p_n, Q = Q _#
