The rotary pump includes a rotor secured to the drive shaft for co-rotation therewith and a plurality of cells for feeding the liquid, each cell constituting a separator for gas -rich liquid upon rotation of the rotor. A stationary shaft extends in the axial bore between the rotary pump and the discharging chamber. A connecting arrangement is provided in the drive shaft and stationary shaft for selectively connecting each cell with the discharging chamber. Also provided is an ejector for ejecting into the discharging chamber the gas-rich liquid separated in the cells through the connecting arrangement. The gas-rich liquid gathers at inner portions of the cells due to a centrifugal force and is discharged by mesns of the ejector through the connecting arrangement.
