Abstract: A pumping mechanism is disclosed. The pumping mechanism may include a barrel formed of a barrel substrate and including a first end surface, a second end surface opposite the first end surface, and a bore between the first and second end surfaces. Each of the first and second end surfaces and the bore is coated with a metal plating. The pumping mechanism may further include a plunger formed of a plunger substrate and configured to be slidably disposed in the bore in barrel, the plunger substrate having a tribological coating.

Abstract: A cryogenic pump configured for pressurizing a cryogenic fluid is provided. The cryogenic pump includes a warm end portion adapted to not contact cryogenic fluid during operation of the pump and including one or more driving components. The cryogenic pump includes a cold end portion adapted to contact cryogenic fluid during operation of the pump and including a pump inlet and a pump outlet. An insulating arrangement including an insulator plate is arranged between the warm end portion and the cold end portion and defines a first air gap between the cold end portion and the insulator plate.
