The two main types of molecular pumps are the diffusion pump and the turbomolecular pump. Both types of pumps blow out gas molecules that diffuse into the pump by imparting momentum to the gas molecules. Diffusion pumps blow out gas molecules with jets of an oil or mercury vapor, while turbomolecular pumps use high speed fans to push the gas.
[2]: 80 The V-2 rocket design used hydrogen peroxide decomposed through a Walter steam generator to power the uncontrolled turbopump [2]: 81 produced at the Heinkel plant at Jenbach, [3] so V-2 turbopumps and combustion chamber were tested and matched to prevent the pump from overpressurizing the chamber. [2]: 172 The first engine fired ...
