Hydraulic pump (2) that is internally provided with a centrifugal rotor (3) connected to one of the ends of the shaft (4) and a fan (5) placed on the other end of the shaft (4), also having an open motor (6) placed between the rear flange (7) and the front flange (8), all of them passed over by the said shaft (4). The front shaft (8) is comprised of a cylindrical disk (9) which has in its central portion a projection (10) presenting an anterior counterbore (11) and a posterior counterbore (12) of smaller dimension and, between them, an open hole (13) from which projection (10) a lateral opening (13a) is derived. The rear flange (7) is comprised of a disk (19) that presents a central projection (20), and which counterbore (21) has an open hole (22); the upper portion of the flange (7) has an internal lateral contour (23) forming a diametral edge (24); and the lower portion of the flange (7), in its external lateral contour (25), presenting diametral rims (26) comprised of open holes (27).
