ActiveCentrifugal liquid hydrogen pumps—Technical specification
离心式液氢泵 技术规范
Application Summary AI generated
This standard specifies the technical requirements for the design, materials, performance testing, and safety features of centrifugal pumps used to transfer liquid hydrogen. It is applied in the aerospace, hydrogen energy, and cryogenic industrial sectors, specifically for pumps handling liquid hydrogen at extremely low temperatures (around -253°C) in fueling stations, rocket propellant systems, and hydrogen liquefaction plants. The standard ensures operational reliability, leak prevention, and thermal insulation performance under cryogenic conditions.
