Abstract
A support structure for the rotatable housing of a liquid ring pump includes a stationary structure disposed circumferentially around the housing, and a plurality of rollers rotatably and removably mounted on the stationary structure. The rollers support the housing for rotation, and they are distributed axially along and circumferentially about the housing so that any one roller can be removed (e.g., for repair or replacement) without disturbing operation of the pump.
