摘要：
A vacuum pumping device of the invention comprises a motor (1) driving a multi-stage dry mechanical pump (2) in which the stages (5, 6, 7, 8) are connected successively in parallel and then in series in a plurality of successive configurations, each of which is selected to optimize the pumping speed in the current pressure range. This makes it possible to lower pressure inside an enclosure (100) quickly while reducing the volume of the pump and the energy consumed by the pump by about 40% compared with a traditional pump having a speed that is sufficient to obtain the same rapidity of pumping.
