Abstract
A centrifugal pump for handling abrasive-laden fluid is described. A centrifugal pump system for handling abrasive-laden fluid includes an impeller including an annular balance ring extending longitudinally on a top side of the impeller and an annular skirt extending longitudinally on a bottom side of the impeller, one of the annular balance ring, the annular skirt or a combination thereof having portions defining a plurality of apertures, wherein the plurality of apertures form an abrasive-media relief path that bypasses at least a portion of a clearance gap and merges with a primary working-fluid flow path. A centrifugal pump impeller includes a bottom shroud, an annular skirt extending longitudinally upstream from the bottom shroud, the annular skirt encircling a central hub, and the annular skirt having an aperture extending through a thickness of the annular skirt.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
