Patent ID: 7513759

Claim:
A plunger pump housing comprising: a suction bore comprising a first portion with substantially circular cross-sections, a second portion comprising a cylindrical area followed by an outwardly flared transition area, a suction bore shoulder between said first and second portions, and a first centerline; a discharge bore comprising a first portion with substantially circular cross-sections, a second portion comprising a transition area, and a second centerline, said first and second centerlines being colinear; a plunger bore comprising a proximal packing area and a distal transition area, said packing area having substantially circular cross-sections and a third centerline, said third centerline being coplanar with said first and second centerlines; and an access bore comprising a distal retainer portion with circular cross-sections, a proximal transition area, an access bore shoulder between said proximal transition area and said distal retainer portion, and a fourth center line, said fourth centerline being colinear with said third center line; wherein said suction bore outwardly flared transition area and said suction bore cylindrical area each have at least one elongated cross-section substantially perpendicular to said first centerline and with a long axis substantially perpendicular to a plane containing said first, second, third and fourth centerlines; wherein said discharge bore transition area has at least one elongated cross-section substantially perpendicular to said second centerline and with a long axis substantially perpendicular to a plane containing said first, second, third and fourth centerlines; wherein said plunger bore transition area has at least one elongated cross-section substantially perpendicular to said third centerline and with a long axis substantially perpendicular to a plane containing said first, second, third and fourth centerlines; and wherein said access bore proximal transition area has at least one elongated cross-section substantially perpendicular to said fourth centerline and with a long axis substantially perpendicular to a plane containing said first, second, third and fourth centerlines.
