ABSTRACT:
A centrifugal pump is provided including a first stationary seal ring mounted from the pump housing for slight axial and radial shifting relative thereto. The stationary seal ring includes inner and outer large and small diameter axially facing seal faces and the impeller of the pump supports a pair of inner and outer seal rings each supported from the impeller for limited radial and axial shifting relative thereto. The inner and outer seal rings axially oppose and are disposed in sliding contact with the inner and outer seal faces of the stationary ring. Also, the impeller of the pump and the tangential outlet thereof include structural features which greatly facilitate usage of the pump in pumping thick fluids.
