ABSTRACT:
A gas removable pump for liquid comprising a housing having an inlet for introducing the liquid thereinto and an outlet for feeding the liquid therefrom, a drive shaft extending into the housing and having formed therein an axial bore, a rotary pump disposed within the housing, and a discharging chamber defined within the housing and separated from the rotary pump in a liquid-tight manner. 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 injector for ejecting into the discharging chamber the gas-rich liquid separated in the cells through the connecting arrangement.
