Abstract
A flow-through centrifuge free of rotating seals. The centrifuge includes a frame having three spaced apart horizontal plates which carry a central bowl, a countershaft and a tube-supporting hollow shaft. A motor is arranged to drive the frame at an angular velocity of .omega.. The countershaft is driven by a stationary pulley on the motor and drives the bowl at an angular velocity of 2.omega.. The motion of the countershaft is also transferred to the tube-supporting hollow shaft by a pulley coupling having a ratio which effects rotation of the hollow shaft, with respect to the frame, at an angular velocity of -.omega..
