The goal of a single (dry) pump capable of reaching high vacuum and itself exhausting to atmospheric pressure has long existed in the vacuum field. The recent development of a single shaft high speed pump mechanism has gone some considerable way to achieving this goal. The pump exploits molecular drag and fluid dynamic mechanisms. It will be discussed in terms of its science of operation, internal flow mechanisms and technology innovations enabling the mechanism to be produced in volume quantities. Further development and application examples will be discussed to illustrate system-simplification which the pump provides.
