A method and apparatus for separating cell suspension into centrate and concentrate includes a solid wall rotatable centrifuge bowl (82). A single use rotatable core (88) is positioned in the bowl and bounds a cavity (90) which serves as a separation chamber. The bowl rotates about an axis (84). An inlet tube (92) and an outlet tube (102) extend along the axis in the bowl cavity. The centripetal pump (98) in the cavity is in connection with the outlet tube. The centrate discharge pump (120) is in connection with the outlet tube. A pressure damping reservoir (122) is fluidly connected between the outlet tube and the discharge pump. At least one control circuit (142) is operative to control the apparatus to maintain a positive pressure above atmospheric pressure within the cavity, so as to maintain the cell suspension away from at least one seal (106) that bounds the interior of the cavity.

A method for lowering the pressure inside the hood interior of a separator arrangement with a separator with a rotatable drum includes rotating the rotatable drum about a vertical rotation axis. Before processing a product that is to be processed, a liquid is first directed through the drum and the pressure inside the hood interior is lowered, by a device, as a result of rotations of the drum in the manner of a jet pump. After the pressure inside the hood interior has been lowered sufficiently, then the actual processing of the product that is to be processed is performed.

A centrifuge able to discharge moisture through a separate moisture outlet by separating moisture from oil when spraying oil through a nozzle of a rotor, thereby removing moisture from oil without using a separate skimmer, and a purifier system including the same. The centrifuge includes a casing, a shat, a stand tube and a rotor. The casing has an oil inlet, an oil outlet, a moisture outlet and an air inlet. Moisture separated from oil sprayed through a nozzle of the rotor is discharged along with air out of the casing through the moisture outlet. An amount of air identical to the amount of the air discharged through the moisture outlet is introduced into the casing through the air inlet.
