Abstract: A valve assembly for an artificial lift system can include a cage defining a bore therethrough, a valve seat, and a ball disposed within the cage. In a closed position, the ball seals against the valve seat. Upon application of sufficient pressure, the ball lifts from the valve seat to open the valve and allow fluid to flow through the bore. An interior surface of the cage surrounding the bore includes a flow profile that improves fluid flow through the cage. The flow profile can include a plurality of flanges protruding inwardly into the bore from the interior surface and extending helically along a longitudinal length of the cage.

Abstract: Artificial lift pump components such as couplings are disclosed, all having a body formed from a selected material, the body having an inner diameter and an outer diameter, a first surface treatment introducing carbon, nitrogen, boron into the material to form a first and hard layer, and a second layer defined as an deposited coating to the first layer that is also made of a carbon, nitrogen, or boron and is further characterized as being ceramic like (hard) and having a low-friction.
