    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.
