Abstract: In a system for dispensing a cryogenic fluid, a bulk tank is configured to contain a supply of a cryogenic liquid. A sump is configured to receive cryogenic liquid from the bulk tank. A first positive-displacement pump is positioned within the sump and is configured to be submerged within and pump cryogenic liquid stored within the sump. A second positive-displacement pump is positioned within the sump and is configured to be submerged within and pump cryogenic liquid stored within the sump. A vaporizing heat exchanger is configured to receive and vaporize cryogenic liquid pumped from the first pump and/or the second pump.
