Abstract
A sleeve filter centrifuge comprises between the closed end wall of a centrifugal drum and a base portion movable relative to this end wall a flexible, extendible dividing wall, for example in the form of a bellows or a folded membrane. This dividing wall provides a seal between a displacing shaft bearing the base portion and the inner chamber of the centrifugal drum accommodating the suspension and prevents any exchange of substances, which, for example, impairs sterilization, between the process area of the centrifugal drum and the machine frame side of the sleeve filter centrifuge.
