Zusammenfassung:	An apparatus and process for cooling down a liquid hydrogen or other cryogenic fluid comprising a pump (5) and configured to allow for a quick startup that also helps minimize hydrogen losses. Some embodiments can utilize a blow-by circuit configured and arranged to support the cryogenic cooldown operation for the pump that can minimize hydrogen loss while allowing substantially improved pump startup times. Some embodiments can utilize at least one temperature sensor to monitor temperature and an adjustable control valve that can facilitate the flow of the fluid utilized to perform the cooldown of the pump.
