Abstract

A centrifugal separator for separating at least one liquid phase from a liquid feed mixture includes a frame, a drive member and a rotating part. The drive member is configured to rotate the rotating part in relation to the frame around an axis of rotation, and the rotating part includes a centrifuge bowl enclosing a separation space. The centrifuge bowl includes an inlet for receiving the liquid feed mixture, and at least one liquid outlet for a separated liquid phase. The separation space includes a stack of separation discs arranged coaxially around the axis of rotation. The separation discs include distance members arranged so that interspaces are formed between adjacent separation discs in the disc stack. A plurality of said separation discs include a throttle member other than the distance members and arranged to cause a decrease in pressure to a liquid flowing through the disc stack in the interspaces. The plurality of separation discs are configured to allow for a radial flow of liquid in the direction from the outer periphery of the discs to the inner periphery of the discs throughout a major portion of the discs.
