In a centrifuge rotor having intermittently opening peripheral outlets for discharging separated solids and having a paring chamber with stationary paring means for discharging separated liquid, an arrangement is provided to prevent air from passing into the paring channel when opening of the peripheral outlets causes the liquid level to move radially outward in the rotor. The arrangement includes an annular partition of the rotor which allows liquid flow from its separating chamber to its paring chamber during normal operation but which prevents some liquid in the paring chamber from returning to the separating chamber due to opening of the peripheral outlets, and first and second stationary annular discs coaxial with the rotor and operable while the peripheral outlets are opened to maintain, respectively, a first liquid seal between the separating chamber and the paring channel and a second liquid seal between the paring channel and the atmosphere surrounding the rotor.
