摘要： 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.

摘要： A fluid end for use with a power end. The fluid end comprises a plurality of fluid end sections positioned adjacent one another. Each section includes a single horizontally positioned bore. A plunger is installed within the bore and includes a fluid passageway. Low-pressure fluid enters the bore through the plunger and high-pressure fluid exits the fluid end through an outlet valve installed within the bore. The intake of low-pressure fluid within the fluid end section is regulated by an inlet valve installed within the plunger. Low-pressure fluid enters the plunger through an inlet component attached to both the plunger and an inlet manifold.

摘要： A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.
