摘要： A multi-piece fluid end that can be produced with fewer raw materials and at a lower cost. In one embodiment, a fluid end is formed from a first body attached to a separate second body. Their respective external surfaces may be engaged flushly, partially, or via one or more spacer elements. In some embodiments, the body pieces are flangeless to reduce stress on the fluid end. The second body may have a plurality of bores that are alignable with a plurality of corresponding bores formed in the first body. The second body may be connected to a power end using a plurality of stay rods. In other implementations, more than two body pieces may be utilized.

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.
