A vane for a rotary positive displacement pump with a vane rotor has a body (122) in which an inertial damper is mounted. The damper includes at least one inertial dampening member (102) with a mass smaller than the mass of the vane (120) and radially movable within a seat (101) formed in the body, and a pair of resilient members (103a, 103b) opposing the radial movement of the dampening member (102). The invention also concerns a pump using the vane and a pumping method using such a pump. |
