A washpipe assembly is configured to form a fluid tight seal between a rotating and non-rotating component. The washpipe assembly has a washpipe, a static seal assembly coupled to one end of the washpipe, and a dynamic seal assembly coupled to an opposite end of the washpipe. The dynamic seal has a seal disposed within an outer housing. The seal is contained within a seal cavity formed by the outer housing and an outer diameter of the washpipe. The dynamic seal assembly is rotatable relative to the washpipe while the seal maintains sealing contact with the outer diameter of the washpipe.

Aspects of the present disclosure relate to reciprocating pumps, and specifically to power end rod assemblies, for pumping operations such as wellbore fracturing or drilling operations. The power end rod assembly comprises a power end rod comprising a body, a flanged end portion, and a shank portion. A wear plate is removably coupled to the shank portion by a securing member.

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

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.

A screw gland assembly that comprises a body having threads formed on an outer surface of the body. A piston retainer coupled to the body, and a piston disposed within the body. A biasing member disposed between the piston retainer and the piston such that the piston is moveable relative to the body against a bias force of the biasing member.

Energized screw gland

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.
