摘要： A modularized integrated non-coaxial multiple chamber dry vacuum pump is formed by at least two modularized vacuum chambers that can be integrated into a solid multiple stage dry vacuum pump. These chambers are connected in serial to allow gas to pass through and be discharged directly to the atmosphere. Each chamber contains a pair of lobes of its own and at least one chamber does not share at least one coaxial axle with another chamber. At least two chambers do not share all co-axial(s) and can have their own power drive at different RPMs from either different motors or transmissions.
