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.
