Abstract

Electromagnetic pump with oscillating core, connected to a hydraulic device, to transfer a fluid into the hydraulic device. The pump includes a containing body, a tubular element of amagnetic material, a core of ferromagnetic material sliding coaxially to the tubular element, an electromagnetic unit arranged around the core and coaxial to the tubular element to generate an alternating magnetic field and cause the core to slide axially and alternately with respect to the tubular element. The tubular element includes, in one piece, a first part, projecting outside both the containing body and the electromagnetic unit and having an attachment configured to be selectively associated, directly or indirectly, with mating attachment elements of the hydraulic device, and a second part disposed inside both the containing body and the electromagnetic unit and having an axial cavity in which the core slides. The tubular element further includes, in one piece, a flange between the first part and the second part and configured to allow the direct mounting of the tubular element to the containing body and the electromagnetic unit.
