Abstract
A fluid end made of a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section is made of a housing having a discharge bore and an intake bore formed therein. A fluid routing plug is installed within each housing and is configured to route fluid throughout the housing and between the discharge and intake bores. The fluid routing plug carries seals that engage sealing surfaces formed within the housing. A number of features, including the location of seals within bore walls and carbide inserts within valve guides, aid in reducing or transferring wear within each housing.

A fluid end section, comprising:
- a housing having a longitudinal axis and a first bore extending along the longitudinal axis;
- a fluid routing plug situated within the first bore, the fluid routing plug comprising a body having opposed first and second surfaces interconnected by an intermediate outer surface;
- a first valve configured to engage the first surface of the fluid routing plug;
- a second valve configured to engage the second surface of the fluid routing plug;
- and
- a valve guide configured to prevent axial movement of the first valve, the valve guide comprising:
