Abstract
A centrifuge includes a rotatably mounted drum, a drive motor, a drum shell made of metal and a vertical axis of rotation. The drum has a feed tube, a paring chamber with a paring disk for leading away clarified or separated liquid, and a solids discharge. The drum has, above the paring chamber, at least two sealing chambers, which lie one axially above the other and which each have a sealing disk protruding into the respective sealing chamber. The centrifuge includes at least one supply channel for supplying a sealing medium to one of the sealing chambers or includes, for each sealing chamber, at least one supply channel for supplying a sealing medium to the respective sealing chamber.

1-20. (canceled)
A centrifuge configured to separate or clarify a flowable product or a flowable suspension into at least two phases in a centrifugal field in continuous operation, wherein the centrifuge comprises:
- a rotatably mounted drum drivable by a drive motor to rotate about a vertical axis of rotation;
- and
- a drum shell made of metal,
- wherein the rotatably mounted drum comprises
- a feed pipe and at least one gripper chamber with a gripper configured to discharge separated or clarified liquid;
- and
- at least two axially superimposed sealing chambers arranged above the gripper chamber, wherein each of the at least two axially superimposed sealing chambers has a sealing disk projecting into the respective one of the at least two axially superimposed sealing chambers,
- wherein the rotatably mounted drum further comprises
- at least one feed channel configured to feed a sealing medium into one of the at least two axially superimposed sealing chambers, or
- at least one feed channel configured to feed the sealing medium into the respective one of the at least two axially superimposed sealing chambers sealing chambers.

A method, comprising:
- providing a centrifuge configured to separate or clarify a flowable product or a flowable suspension into at least two phases in a centrifugal field in continuous operation, wherein the centrifuge comprises:
- a rotatably mounted drum drivable by a drive motor to rotate about a vertical axis of rotation;
- and
- a drum shell made of metal,
- wherein the rotatably mounted drum comprises
- a feed pipe and at least one gripper chamber with a gripper configured to discharge separated or clarified liquid;
- and
- at least two axially superimposed sealing chambers arranged above the gripper chamber, wherein each of the at least two axially superimposed sealing chambers has a sealing disk projecting into the respective one of the at least two axially superimposed sealing chambers,
- wherein the rotatably mounted drum further comprises
- at least one feed channel configured to feed a sealing medium into one of the at least two axially superimposed sealing chambers, or
- at least one feed channel configured to feed the sealing medium into the respective one of the at least two axially superimposed sealing chambers sealing chambers;
- supplying the flowable product or flowable suspension to the feed pipe to separate or clarify the flowable product into at least two phases;
- filling one of the at least two axially superimposed sealing chambers with sealing liquid via the feed channel leading into the at least two axially superimposed sealing chambers without additional counterpressure, so that an outlet opening from the at least one feed channel is not immersed in the sealing liquid in the respective one of the at least two axially superimposed sealing chambers until the sealing disk in the respective one of the at least two axially superimposed sealing chambers is immersed in the sealing liquid and overflows into the other one of the at least two axially superimposed sealing chambers, and continue filling until the other one of the at least two axially superimposed sealing chambers fills so that the sealing disk of the other one of the at least two axially superimposed sealing chambers is immersed in the sealing liquid.
