The constructive solution of a rotating volumetric pump with two profiled rotors is presented; each rotor is provided with two triangular-shaped rotating pistons. The calculation relation of the driving power of the volumetric pump is established and the graph P=f (nr) is drawn. Subsequently, the pump is placed in an “in situ” hydraulic network and the pump load and the water transport distance are specified; linear and local pressure losses are calculated, resulting in total pressure loss. The driving power of the pump is determined and V = f (nr) and P=f (nr) is plotted.
