Abstract
A stack of separation discs is adapted to be included inside a centrifugal rotor for separating a liquid including a plurality of axially aligned separation discs having a truncated conical shape with an inner surface and an outer surface and a plurality of spot-formed spacing members extending from a base from at least one of the inner surface and the outer surface for providing interspaces between mutually adjacent separation discs in the stack of separation discs. The plurality of separation discs having spot-formed spacing members are arranged so that a majority of said spot-formed spacing members of a disc are displaced compared to the spot-formed spacing members of an adjacent disc. A centrifugal separator including such a stack of separation discs is also disclosed.
