A method and system for installing and maintaining submerged pumps is disclosed. The submerged pump may be positioned within a product storage vessel. Alternatively the submerged pump may be positioned within a product storage vessel with a sump that is integral with and not removable from the vessel. The pump may used for the movement of products, such as cryogenic liquids, including but not limited to, nitrogen, argon, ethylene, natural gas, nitrous-oxide, carbon-monoxide, hydrogen, helium, and carbon-dioxide. Superior results are obtained with respect to access, maintenance and handling of the pump within a product storing vessel.

In one aspect of the invention, the system may include a liquid hydrogen storage tank that is placed on a mobile carriage. From the liquid hydrogen storage tank, a submerged pump feeds low-pressure liquid hydrogen to a second pump that is external to the tank. This second pump then increases the pressure of the liquid hydrogen and feeds the liquid hydrogen to a vaporizer system. The vaporizer system includes coolant, a coolant tank, a load bank, a third pump, and a diffusion bonded compact heat exchanger (DCHE) to transfer heat from the coolant to the liquid hydrogen. To further help heat the coolant, heat exchangers may be included to cool systems of the vehicle and recover waste engine heat. After the vaporizer converts the liquid hydrogen to its gaseous form, the gaseous hydrogen is discharged to an external vehicle or tank.
