    Abstract: A fluid end assembly made of a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a plurality of individual components joined together in a row. Two sets of fasteners are used to secure various components of each fluid end section together. When the fluid end section is assembled, a first set of fasteners is in a spaced relationship with and faces a second set of fasteners. At least one component making up the multi-piece fluid end section is configured to have a plurality of stay rods attached thereto. The stay rods interconnect the fluid end assembly and a power end assembly.

    Abstract: A closure element for a fluid end assembly that has two or more recessed grooves formed in its outer surface. The grooves are axially offset. A seal is placed in one and only one of the grooves. As wear occurs, the seal is relocated to one of the other grooves. Instead of a series of axially offset grooves in a single closure element, a kit may be formed from two or more otherwise identical closure elements, each with a single recessed groove at a different axial position. Another closure element has a series of ledge-like surfaces defining spaces within which a seal may be received. One outer surface surrounds one or more of the other surfaces. A seal is placed in one and only one of the spaces. As wear occurs, the seal is relocated to one of the other spaces.
