Single-entry radial pump with a closed impeller with active blade surfaces or central stream lines of the flow passage between two consecutive blades similar to the camber line of the blades achieved by Kaplan's method of conformal representation or by means of Pfleiderer's point by point method is characterized by the fact that the impeller has discs (1, 2) and blades (3) shaped in such a way that the cross - sections (5) of its diffuser passages keep the shape of their cross - sections similar to each other, perpendicular to the central stream line of the passage between the blades over its entire length.

La pompe radiale à entrée unique est caractérisée en ce que la roue est dotée de disques (1, 2) et de pales (3) mis en forme de manière à ce que les coupes transversales (5) des passages de leur diffuseur aient des formes de coupes transversales similaires les unes par rapport aux autres, perpendiculaires à la ligne de courant centrale du passage entre les pales sur l'ensemble de sa longueur.
