Abstract
"PERFECTED PUMP, FOR DRIVING LIQUIDS", characterized by the fact that the impeller blades or wings are housed in the rotor core, joined together, two by two, by means of two balancing needles, which couple the pair of blades arranged on the same diameter, which can be arranged in the axial direction, which allows the blade to enter the area occupied by the pressure chamber, significantly increasing its driving effect, and therefore, the performance of the pump.
