Abstract
A double suction, high-speed centrifugal pump includes an impeller with shrouds formed integrally with opposite sides thereof. The impeller is splined on a rotatable shaft within a chamber in a housing. Sealing rings are fixed within the chamber and axially facing sealing surfaces and walls are formed in the shrouds and sealing rings respectively to help keep liquid from leaking from the impeller discharge and back to the inlet of the impeller. Means are provided for adjusting the axial distance between each of the sealing walls of the two shrouds and the center of the impeller chamber. Also, means are provided for locating the impeller axially within the impeller chamber to precisely position the sealing surfaces with respect to the sealing walls.
