A centrifugal separator for separation of a cell culture mixture includes a stationary frame, a rotatable assembly and a drive unit for rotating the rotatable assembly relative the frame around a vertical axis of rotation. The rotatable assembly includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged to rotate around an axis of rotation. The rotor casing includes a mechanically hermetically sealed inlet and first and second mechanically hermetically sealed liquid outlets. The second mechanically hermetically sealed outlet is arranged at an axial end of the rotor casing opposite and arranged so that a separated cell phase is discharged at the rotational axis. The rotatable assembly includes an exchangeable separation insert and a rotatable member.

Centrifugation systems are provided that have a non-contact seal assemblies including an upper guard and a skirted pivot, as well as a pressure source that provides a gas flow between the upper guard and a surface of the skirted pivot. In some embodiments, the non-contact seal assembly further includes a lower guard having one or more capillary channels defined on an upper surface.

A separator for centrifugally processing a flowable product includes a rotating system with at least one rotatable drum delimiting a centrifugal chamber and at least one drive spindle for rotating or driving the drum. At least one non-rotating housing surrounds the drum. A mounting device for mounting the drive spindle in a mounting receiving housing is arranged or formed on the housing. A support arrangement is configured between the outer circumference of the bearing device and the inner circumference of the bearing receiving housing. The support arrangement is designed to provide on the whole an elastic radial support of the bearing device on the bearing receiving housing, and thus on the housing.

A machine is intended to separate the colloidal solids from a fluid by using centrifugal force. The machine has a vertical cylinder mounted at the end of a hollow shaft with sludge dispenser and clear water dispenser nozzles. The drum is rotated at high speed by a motor and pulley assembly fixed parallel. The effluent is fed to the separation chamber through the hollow shaft and the sludge is pushed out though the nozzles fixed at the periphery of the drum and clear water flows out through the nozzles fixed at the doubled chambered hollow shaft.
