Abstract
A sealing system for a high pressure pump operable above 15,000 psi includes a first engagement face formed as part of the vessel and defining an opening into the vessel bore, the first engagement face having a concave cross-section. A seal member is at least partially received within the bore and defines a second engagement face, the second engagement face having a convex cross-section. A retaining member is coupled to the seal member and is operable to move the seal member from an initial contact position with the vessel to a sealing contact position, wherein the first engagement face and the second engagement face define a first contact angle with respect to the axis in the initial contact position and a second contact angle that is greater than the first contact angle in the sealing position.
