high pressure vacuum gas pump

  • 2 Basic calculations - pfeiffer-vacuum

    With this process pump we reach fore-vacuum pressure of 3.0 Pa with a gas throughput of 0.24 hPa m 3 s-1. With a maximum turbopump fore- vacuum pressure of 3.3 hPa, this configuration is conservative despite the thermally demanding process gas argon. The process gas is admitted to the chamber (1) via a mass flow controller (5).

    This high vacuum pump uses a shaft rotating at high speed with a series of multibladed rotors on the shaft. The rotors alternate with multibladed stators (static rotors). The principle of operation is that as the shaft rotates, the gas molecules are hit by the angled blades of the rotor, knocking the gas molecules both forward and downward.
