An electric pump (10, 110) for moving a liquid, comprising a containment jacket (11, 111) which encloses: - a mechanical section, which comprises an assembly for moving said liquid which comprises one or more impellers, interleaved by diffusers, keyed on a driving shaft, - an electromechanical section, comprising an electric motor, contained in a shell and comprising in turn a rotor and a stator that surrounds said rotor, said rotor being keyed on said driving shaft, said electric pump (10, 110) comprising, at the ends of said jacket (11, 111), a first cover (20, 120) and a second cover (21, 121), said second cover (21, 121) having an intake port and a delivery port which are fluidically connected to said mechanical section, said jacket (11, 111) being provided monolithically, characterized in that said jacket is provided with one or more through holes, the axis of extension of which is perpendicular to the axis of extension of said jacket, said one or more through holes being located at said electromechanical section, in a portion thereof, said portion being proximate to said mechanical section and being substantially comprised between said shell for the containment of said motor and the interface between said mechanical section and said electromechanical section, and in that the electric pump (10, 110) has a wet portion inside said electromechanical section, which is separated from said portion of said electromechanical section and surrounds said shell, said wet portion being shaped in order to provide for a circumferential partition wall between the shell and the jacket so as to create a path for the passage of said liquid between said intake port and said delivery port, said liquid skimming: - the outer lateral surface of said shell, moving from said intake port toward said first cover, - the inner lateral surface of said jacket, moving from said first cover toward said delivery port. - a mechanical section, which comprises an assembly for moving said liquid which comprises one or more impellers, interleaved by diffusers, keyed on a driving shaft, -
