Original abstract

Seal‑less e‑powered (canned‑motor) centrifugal pumps are attractive for rocket propellants, in this case liquid‑oxygen (LOX) transfer because they eliminate dynamic seals and potential leakage paths, but they impose tightly coupled constraints across hydraulics, rotordynamics, electromagnetics and thermal management. This contribution reports a design and validation methodology for a high‑speed pump targeted at LOX, together with lessons learned from an instrumented water‑surrogate test campaign.
