1. A fluid routing plug, comprising:
a body having a suction surface and an opposed discharge surface, in which the suction and discharge surfaces are joined by an outer intermediate surface; and in which the body has a central longitudinal axis that extends through the suction and discharge surfaces;
a plurality of suction fluid passages formed in the body, each of the plurality of suction fluid passages interconnecting the intermediate surface and the suction surface of the body;
a plurality of discharge fluid passages formed in the body, each of the plurality of discharge fluid passages interconnecting the suction surface and the discharge surface of the body;
a first recessed cavity formed in the suction surface;
a first annular insert disposed within the first recessed cavity and having a first tapered surface;
a second recessed cavity formed in the discharge surface and comprising a base surrounded by a side wall; and
a second annular insert disposed within the second recessed cavity and having a second tapered surface, at least a portion of the first annular insert engaging the base;
in which the plurality of discharge fluid passages open at the base; and
in which an outer diameter of the body surrounding the first recessed cavity and the first tapered surface is greater than an outer diameter of the body surrounding the second recessed cavity and the second tapered surface.
