A fluid circulation device includes a circuit of the fluid to be pumped, with a rigid cavity closed off by a soft membrane that cooperates with drive members driven by a motor in to-and-fro movements. The face of the drive members intended to cooperate with membrane is connected via a conduit to a vacuum pump able to apply by suction the membrane against the face of the drive members, so as to create a rigid connection between the drive members and the membrane that then exactly follows the to-and-fro movements imposed by the drive members. |
