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.

A cryogenic pump configured for pressurizing a cryogenic fluid, the cryogenic pump comprising:
- a warm end portion adapted to not contact cryogenic fluid during operation of the pump and including one or more driving components;
- a cold end portion adapted to contact cryogenic fluid during operation of the pump and including a pump inlet and a pump outlet;
- and
- an insulating arrangement including an insulator plate arranged between the warm end portion and the cold end portion and defining a first air gap between the cold end portion and the insulator plate.
A cryogenic pump configured for pressurizing a cryogenic fluid, the cryogenic pump comprising:
- a warm end portion adapted to not contact cryogenic fluid during operation of the pump, the warm end portion including a shaft and a load plate for driving movement of a plurality of pushrods, at least a portion of the plurality of pushrods being contained in a pushrod housing;
- a cold end portion adapted to contact cryogenic fluid during operation of the pump and including a pump inlet and a manifold defining a pump outlet;
- and
- an insulating arrangement including an insulator plate arranged between the pushrod housing and the manifold and defining a first air gap between the cold end portion and the insulator plate and a second air gap between the insulator plate and the warm end portion.
An insulating arrangement for a cryogenic pump configured for pressurizing a cryogenic fluid, the cryogenic pump including a warm end portion adapted to not contact cryogenic fluid during operation of the pump and including one or more driving components and a cold end portion adapted to contact cryogenic fluid during operation of the pump and including a pump inlet and a pump outlet, the insulating arrangement comprising:
- an insulator plate arrangeable between the warm end portion and the cold end portion so as to define a first air gap between the cold end portion and the insulator plate and a second air gap between the insulator plate and the warm end portion.
