Abstract:
Radial pump (1) comprising a stator (3) comprising an external stator (30) and an internal stator (32) defining an annular cavity (11) therebetween, and an impeller (5) rotatably housed between said stators (30; 32). The suction (7) is fashioned at a central portion of the internal stator (32), whereas the delivery (9) is fashioned at a radially external peripheral portion of the external stator (30). The impeller (5) comprises a plurality of deformable vanes (50, 51, 52) movable inside the annular cavity (11) and in slidable contact with the internal surface of the external stator (30). In every position of the impeller (5) with respect to the stator (3) at least two deformable vanes (51) are sealed in the portion of the annular cavity (11) between the suction (7) and the delivery (9) to isolate the delivery (9) from the suction (7). The impeller (5) is rotatable about a central internal axis (Al) offset with respect to the central external axis (AE) of the external stator (30), where the rotational eccentricity of the impeller (5) with respect to the external stator (30) determines a deformation of the deformable vanes (50, 51, 52) that contributes to the generation of flow rate of said pump (1).
