Abstract (en)
[origin: WO2017012825A1] The invention relates to a centrifugal pump with a rotor having at least one blade (4), and to a method for configuring the profile of a blade (4). The blade (4) has a profile which is obtained by superposing a symmetric profile (10, 11) with at least one additional profile (12, 13) and a camber line whose blade inlet angle is smaller than 0°.
