A self-contained device for pumping supersonic gas flows. The pumping device consists of a chemically activated material capable of chemical reaction with the gas mixture to be pumped, thermal ballast material, a hermetically sealable vessel for containing the chemically active material, and internal surfaces to provide gas flow passages. The internal gas flow passages are geometrically prescribed to accept a supersonic gas flow, to induce a stable normal shock, to diffuse the subsonic flow obtained after the normal shock, and to distribute the low velocity, subsonic gas flow to the reactive chemical pump material.
