A pump for transferring fragile and aggressive fluids such as human blood and comprising a chamber along with one or more fluid inlet ports (16, 17) arranged in oppositely disposed relationship on the chamber, and at least one outlet port (18) arranged transversely and medially of the inlet ports. A rotor assembly (20) is positioned within the pumping chamber having a core (21) in the form of a first surface of revolution and having a dual-conical configuration converging toward opposed polar end regions and with an axis of rotation extending between the polar regions. At least one shroud (23) is provided spaced outwardly of the surface of the core. The rotor can include a plurality of radial vanes (127) mounted on the outer surface of the dual cones forming the dual-conical configuration.

L'invention concerne une pompe pour le transfert de fluides fragiles et agressifs comme le sang humain, qui comprend une chambre avec un ou plusieurs orifices d'entrée (16, 17) disposés en relation opposée sur la chambre, et au moins un orifice de sortie (18) en position transversale et médiane par rapport aux orifices d'entrée. Un assemblage rotor (20), placé dans la chambre de pompage, a une partie centrale (21) présentant une première surface de révolution et ayant une configuration en cône double à convergence vers des régions polaires terminales opposées, avec un axe de rotation qui s'étend entre les régions polaires. Il existe au moins une enveloppe (23) espacée vers l'extérieur par rapport à la surface de la partie centrale. Le rotor peut comporter plusieurs aubes radiales (127) montées sur la surface externe des deux cônes formant la configuration à double cône.
