What it is
How it works
General reference — not yet source-verifiedA rotary vacuum pump removes gas by trapping it inside a rotating pumping mechanism and moving it toward the exhaust side. A two-stage arrangement uses two pumping stages in series to improve vacuum performance compared with a single-stage design.
Where it fits in the process flow
General reference — not yet source-verifiedA rotary vacuum pump supports equipment that requires reduced pressure rather than atmospheric operation. A pump of this class commonly serves as a backing pump for vacuum systems and as an auxiliary pump for process tools and support hardware.
Applications
General reference — not yet source-verifiedA rotary vacuum pump is used in vacuum generation for laboratory and industrial equipment. A pump of this class is commonly used on systems that need rough vacuum for pump-down and gas removal.
