Abstract
Piston-impeller pump, standing, essentially characterized by the fact that arranged between the second rotary shaft protection fairing and the static lower neck of the motor anchor plate, a radial bearing operatively arranged to prevent oscillations of the upper end of said rotary cowl originally coupled by a lower end to the drive shaft of the pump, and because the motor anchor plate has a rib located concentrically to the motor shaft, which acts as a means of plugging the neck on said plate and as a seat axial of one of the parts of the radial centering bearing of the upper end of the fairing.
