Aspects of the present disclosure relate to locking assembly apparatus for piston apparatus and pony rod apparatus of pump systems (such as mud or frac pump systems), and related methods. In one aspect, the locking assembly is a mechanical locking assembly used to quickly and simply lock and unlock (e.g., release) a piston apparatus to and from a pony rod apparatus.

Locking assembly apparatus for pump systems, and related methods

Aspects of the disclosure relate to locking assembly apparatus and methods for fluid ends, and associated components thereof. In one implementation, a locking assembly for fluid ends includes a first actuator and a second actuator disposed at least partially below the first actuator. The second actuator includes one or more coupling surfaces disposed in coupling engagement with one or more coupling surfaces of the first actuator. The locking assembly also includes a plurality of wedges disposed about the second actuator and movable between an unlocked position and a locked position.

Locking assembly apparatus and methods for fluid ends

A reciprocating piston of a positive displacement pump has a piston body with a plurality of cooling fins on one or more exterior surfaces of the piston body. A seal coupled to the piston body forms a seal with the walls of a cylinder in the positive displacement pump. A rod moves the piston within the cylinder to cause the displacement of fluid.

Reciprocating piston

A flow control assembly for subsea applications comprises a valve assembly and a damper assembly configured to control fluid flow between an external region and the valve assembly. The damper assembly comprises a damper housing, a damper flowpath extending between the inlet and the outlet of the damper housing, and a flow restrictor apparatus disposed in the damper flowpath to control a damper coefficient of the damper assembly.

Flow control assembly for subsea applications

Embodiments disclosed herein generally relate to a system and method for tensioning a bolt. The bolt tensioning system may be used with variable length connection members, for example studs, in any one or more of the drilling, subsea, and process industries to couple a first member to a second member. The bolt tensioning system may remain coupled to the first member and the second member, while applying tension to all of the bolts at the same time, rather than having to torque or tension each bolt individually. The bolt system may accurately and uniformly tension all bolts in a single operation to provide reliable connections.

Bolt tensioning system

A cartridge retention system includes a retention body, a cartridge assembly, and a retaining flange. The cartridge assembly has a housing coupled to the retention body, a biasing member disposed within the housing, and a piston biased by the biasing member toward the retention body. The retaining flange is coupled to the retention body by the cartridge assembly.
