    • A hydraulic valve seat release system for a fluid end of a high pressure pump, comprised of method and apparatus for releasing a valve seat having a tapered outer diameter for sealingly mating when installed in the tapered interior of a fluid end suction or discharge bore via interference fit. The fluid end module of the invention includes internal high pressure porting between an exterior surface of the fluid end module and the interior surface of the bore, whereby high pressure fluid may be applied to the tapered surface of the bore and into a fluid channel around the circumference of the tapered outer diameter of the valve seat. The high pressure fluid compresses the outer diameter of the valve seat and expands the interior diameter of the bore in order to disrupt the interference fit between the valve seat and the bore thereby releasing the valve seat.

    • A sealing system for a high pressure pump, in which the pump includes a vessel defining a vessel bore and having an end portion, the vessel bore having a first engagement face and defining a central longitudinal axis, and in which the pump further includes a plunger cooperative with the vessel to increase the pressure of a fluid within the bore, includes a seal member at least partially received within the bore and defining a second engagement face. The sealing system further includes a retaining member in operative contact with the seal member to mate the first engagement face with the second engagement face to inhibit fluid leakage from the bore. The first engagement face includes a first contacting surface having a non-linear cross-section. The second engagement face includes a second contacting surface having a non-linear cross-section in contact with the first contacting surface.

    • A high-pressure fluid pump is operable to pressurize a fluid and includes a hollow stud including a first end, a second end, and a cylindrical space extending between the first end and the second end and a housing fixedly coupled to the first end of the hollow stud. A high pressure cylinder is disposed within the cylindrical space of the hollow stud. The high pressure cylinder includes a bore that extends from a first end to a second end of the high pressure cylinder. A seal head is engaged with the first end of the high pressure cylinder to define a seal therebetween and an end cap is coupled to the second end of the hollow stud and the seal head. The end cap is operable to apply a compressive force to the seal head to compress the seal head against the cylinder and to apply a tensile load to the hollow stud. A plunger is movable within the bore to pressurize the fluid in a space defined by the piston, the seal head, and the high pressure cylinder.
