Abstract
A centrifugal separator for separation of at least two components of a fluid mixture of different densities includes a centrifuge rotor with a sliding bowl bottom movable between a closed position, in which the peripheral ports are closed, and an open position, in which the peripheral ports are open, an inlet channel for supplying hydraulic fluid to a closing chamber between the sliding bowl bottom and the rotor casing in order to hold the sliding bowl bottom in the closed position. The centrifugal separator includes at least one hermetic seal at a second end, other than the first end, of a hollow spindle and the inlet channel for supplying hydraulic fluid to the closing chamber extends through the hollow spindle and is arranged such that the hydraulic fluid is in thermal contact with the at least one hermetic seal when the hydraulic fluid is supplied to the closing chamber.
