1. A fluid end of a pump comprising:
a power end bore formed in a portion of said fluid end, said power end bore having a long axis; a first transitional open area which opens into a cross-bore intersection from said power end bore, said transitional open area is axially opposite, relative to the power end bore long axis, an entry open end opening into the power end bore through a portion of an external surface of the fluid end, a first transitional surface delimits in the radial direction, relative to the power end bore long axis, said first transitional open area, said cross-bore intersection formed in a portion of said fluid end; a discharge bore formed in a portion of said fluid end, said discharge bore having a long axis; a second transitional open area which opens into the cross-bore intersection from said discharge bore, said second transitional open area is axially opposite, relative to the discharge bore long axis, an entry open end opening into the discharge bore through a portion of said external surface of the fluid end, a second transitional surface delimits, in the radial direction, relative to the discharge bore long axis, said second transitional open area; a suction bore formed in a portion of said fluid end, said suction bore having a long axis; a third transitional open area which opens into the cross-bore intersection from said suction bore, said transitional open area is axially opposite, relative to the suction bore long axis, an entry open end opening into the suction bore through a portion of said external surface of the fluid end, a third transitional surface delimits, in the radial direction, relative to the suction bore long axis, said third transitional open area; an access bore formed in a portion of said fluid end, said access bore having a long axis; a fourth transitional open area which opens into the cross-bore intersection from said access bore, said transitional open area is axially opposite, relative to the access bore long axis, an entry open end opening into the access bore through a portion of said external surface of the fluid end, a fourth transitional surface delimits, in the radial direction, relative to the access bore long axis, said fourth transitional open area; an internal surface delimiting an outer boundary of said cross-bore intersection, and an open space is formed within said outer boundary, said internal surface has a spherical geometry conforming to an outline of a sphere, said sphere having a center point in said cross-bore intersection; and wherein the long axis of the discharge bore extends through the transitional open area of said suction bore. |
