Turbopumps Pfeiffer Vacuum
The idea of turbomolecular pumps goes back to the Pfeiffer Vacuum engineer Dr Willi Becker, who invented the first turbomolecular pump in 1958 This is the ancestor of today’s turbopumps Technology Turbopumps belong to the category of kinetic vacuum pumps, which means that gases are moved from the inlet to the exhaust by momentum transferThe turbomolecular pump is a mechanical ultrahighvacuum pump Its design is explained and compared with the molecular pump of Gaede The equations of Gaede for the molecular pump are used in a modified form for the turbomolecular pump taking into consideration also the internal losses due to backdiffusion and leakageThe turbomolecular pump, its design, operation and theory;
