The present contribution deals with the development of a magneto-active pump devoted to ventricular assist device. The actuator studied is a cylindrical linear switched reluctance motor equipped with a unidirectional mechanical valve inside the tubular mover in order to allow a pulsatile flow. On the bases of theoretical results, a demonstrator has been designed and built in the laboratory. Finite element analysis of this demonstrator has performed and preliminary tests are detailed showing the flow and pressure characteristics.
