The scoop is connected to and extends radially from the annular body. The scoop defines a lip and an annulus surrounding the shaft and is disposed on a first axial end of the annular body. The sealing surface is disposed on a second axial end of the annular body opposite from the scoop. The plurality of teeth are disposed into and along an outer perimeter of a portion of the annular body. The channel extends through a portion of the annular body and is fluidly connected to the scoop and to the sealing surface.
