a body having a suction surface and an opposed discharge surface joined by an outer intermediate surface;
in which the body has a central longitudinal axis that extends through the suction and discharges surfaces;
in which the suction surface is configured to engage a suction valve supported by a suction valve guide; in which the suction surface comprises a central opening joined to an outer rim by a tapered surface; in which the tapered surface is configured to engage the suction valve;
in which the discharge surface is configured to engage a discharge valve;
a plurality of suction passages formed within the body, each suction passage having an opening on the intermediate surface of the body; and
a plurality of discharge passages formed within the body; in which each of the discharge passages has an opening on the outer rim of the suction surface;
in which the outer intermediate surface of the body comprises:
an annular shoulder positioned between the opening of each suction passage and the suction surface of the body;
in which the annular shoulder is configured to engage an annular insert such that the annular insert is in a spaced-relationship with the suction valve guide.
