Abstract

A rotation-sensitive pumping device for pumping liquid from one part of a centrifuge to another during rotation thereof comprises a diaphragm mounted on the centrifuge rotor and moveable from one position to another as a function of rotor speed to pump the liquid. The diaphragm is disposed at an angle between two rotating chambers of the centrifuge and, at a given angular velocity of the rotor, the diaphragm is moved by centrifugal force from one position to the other to pump the liquid from one chamber to the other. The diaphragm may include two flexible diaphragms separated by a cavity filled with a fluid. A partition wall may be located in the space between the diaphragms forming cavities between the partition wall and each diaphragm. An aperture is provided in the partition wall for the passage of fluid between the two cavities on motion of the diaphragms.
