Publication number: 20230075447Abstract: 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.Type: ApplicationFiled: November 16, 2022Publication date: March 9, 2023Inventors: Mark S. Nowell, Kelcy Jake Foster, Micheal Cole Thomas, Christopher Todd Barnett, Guy J. Lapointe, Brandon Scott Ayres

Publication number: 20220412346Abstract: 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.Type: ApplicationFiled: September 2, 2022Publication date: December 29, 2022Inventors: Mark S. Nowell, Kelcy Jake Foster, Christopher Todd Barnett, Brandon Scott Ayres, Michael Eugene May, Guy J. Lapointe, Micheal Cole Thomas

Patent number: 11536267Abstract: A fluid end having its fluid flow bores sealed without threading a retaining nut into the walls of each bore. The fluid ends may be assembled using a plurality of different kits, each kit comprising a fluid end body, a component, a retainer element, and a fastening system. The retainer element holds the component within each of the bores formed in the fluid end body and the fastening system secures the retainer element to the body. The fastening system comprises a plurality of externally threaded studs, washers and nuts in some embodiments. In other embodiments, the fastening system comprises a plurality of screws.Type: GrantFiled: March 29, 2021Date of Patent: December 27, 2022Assignee: Kerr Machine Co.Inventors: Mark S.
