Embodiments disclosed herein describe systems and methods for a spring retainer configuration without suction bore grooves, wherein the spring retainer may be secured in place via a keeper. By eliminating the grooves, embodiments may reduce the surface area of the bore intersection, which may slow the rate of material erosion. Accordingly, embodiments may extend the life of a fluid end in high pressure environments.

1. A system for a fluid end block of a high pressure pumping system, the system comprising: a suction bore configured to house a valve, the suction bore including ridges positioned on an upper surface of the suction bore, wherein a first portion of the suction bore housing the valve has a first circumference and a second portion of the suction bore including the ridges has a second circumference, the first circumference being larger than the second circumference, the ridges including a top shelf and a depression;a spring retainer configured to be inserted into the suction bore and be positioned adjacent to the ridges;a stem positioned on the spring retainer, the stem projecting away from the spring retainer in a direction that is perpendicular to the spring retainer, the stem including a first side and a second side, the first side and the second side being planar surfaces extending from an upper surface of the spring retainer to an upper surface of the stem, the stem including a hollow channel extending through the first side of the stem to the second side of the stem, wherein the stem and the spring retainer are a unified piece;a keeper being configured to be positioned adjacent to a cylinder head and couple with the stem, the keeper including rounded ends and a projection, the projection being positioned more proximate to a base of the keeper than a top surface of the keeper, wherein the projection extends in a direction in parallel to the spring retainer and is configured to be inserted into the hollow channel extending through the stem, wherein an entirety of the base of the keeper is positioned with the depression associated with a first ridge of the ridges, wherein the projection on the keeper includes a first portion having a first circumference and a second portion having a second circumference, wherein the second circumference associated with the second portion is smaller than the first circumference associated with the first portion, the first portion having a length that is at least as long as the top shelf of the first ridge, a first axis of rotation associated with the keeper being different than a second axis of rotation of the cylinder head. 2. The system of claim 1, wherein the second portion of the keeper is configured to be inserted into the hollow channel of the stem. 3. The system of claim 2, wherein the first circumference associated with the first portion is larger than a circumference of the hollow channel of the stem. 4. The system of claim 1, wherein the ridges include tapered sidewalls. 5. The system of claim 4, wherein the spring retainer includes tapered sidewalls. 6. The system of claim 5, wherein the tapered sidewalls of the ridges correspond to the tapered sidewalls of the spring retainer. 7. The system of claim 1, wherein the top shelf of the ridges is vertically offset from an upper surface of the spring retainer. 8. The system of claim 1, wherein a sidewall of the keeper is perpendicular to an upper surface of the spring retainer and parallel to the stem. 9. The system of claim 1, wherein when the keeper is positioned adjacent to the cylinder head and the stem, the spring retainer is unable to rotate. 10. The system of claim 1, wherein the cylinder head and the keeper are independent and separable elements.
