Abstract: A liquid ring pump is provided that includes an annular housing having an inner surface forming a housing cavity. The annular housing is filled with an operating fluid during operation of the pump. The operating fluid forms an eccentric liquid ring in the annular housing during operation of the pump. A rotor is disposed in the housing cavity and includes a plurality of rotor blades. A shaft extends into the annular housing into the housing cavity. The plurality of rotor blades extend radially outward from the shaft toward the inner surface of the annular housing. A liner formed from a corrosion resistant material is disposed substantially flush with at least a portion of the annular housing inner surface opposite a plurality of rotor blade ends.

Abstract: A first bore is formed in a liquid ring pump. A shaft is in the first bore. A second bore is formed in the pump and is axially inward of the first bore. A first and second seal are in the second bore and around the shaft. The second seal is axially outward of the first seal. The second seal is free of an abutment axially outward of it and abutting up against it.

Abstract: Textured surface that provides for drag reduction, and therefore efficiency improvements in a liquid ring pump. At least a portion of the surfaces of the pump that contact fluid therein the pump are textured to control boundary layer separation. The texture can be a plurality of dimples are defined therein the surface. The dimples have a predetermined shape, size, density and pattern.
