Abstract

Centrifugal motor-driven pump provided with an impeller rotationally mounted with limited mobility on one end of the rotor shaft of an electric driving motor, which pump is characterized in that it is provided, between the shaft (20) of the rotor (15) the driving motor (3) of the impeller (27), with a motion transmission delay system (30) comprising a circular driving flywheel (31) fixed to one end (25) of said shaft (20) of the rotor (15) and an axial crank pin (36) integral with a hub (37) of said impeller (27), rotating over a large radius area of said flywheel (31) and experiencing a free travel before engaging with said flywheel (31).
