Abstract
Speed reducer for centrifugal pumps with vertical axis, characterized by being constituted by a box inside which are permanently geared two pinions of different number of teeth one by another; These pinions are mounted on four radial ball bearings with double row and the main pinion shaft is supported on an axial bearing also balls. The axes of the pinions come out of the box and are coupled; the greater to the axis of the pump and the smaller to the transmitting tree of the movement.
