Abstract
Liquid ring pumps with rotating liners supported by a bearing fluid (pressurized liquid or compressed gas) have a bearing fluid distribution system that compensates for the radially unsymmetric load on the rotating liner. If the liner bearing fluid is compressed gas, the axial ends of the liner may be either open and unsealed so that expended bearing gas escapes into the liquid ring in the pump, or the axial ends of the Liner may be partly closed by radially inwardly extending end plates. Various mechanical and/or liquid seal structures may be used in conjunction with the end plates to seal the axial ends of the liner and/or to flush the clearances adjacent the axial ends of the liner.
