  2. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.

    A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a ... Steam ejector (vacuum depends on the number of ...

  4. Vacuum brake - Wikipedia

    en.wikipedia.org/wiki/Vacuum_brake

    Vacuum brakes were initially favoured over air brakes because of the ease of producing the vacuum. A vacuum ejector was a simpler and more reliable device, compared to the reciprocating pump. [3] Typically two ejectors are fitted, large and small. The large ejector is used to 'blow off' the brakes, by producing the vacuum, and is then shut off.

  5. Diffusion pump - Wikipedia

    en.wikipedia.org/wiki/Diffusion_pump

    The steam ejector is a popular form of pump for vacuum distillation and freeze-drying. A jet of steam entrains the vapour that must be removed from the vacuum chamber. Steam ejectors can have single or multiple stages, with and without condensers in between the stages. While both steam ejectors and diffusion pumps use jets of vapor to entrain ...

  6. Injector - Wikipedia

    en.wikipedia.org/wiki/Injector

    It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow. Depending on the application, an injector can also take the form of an eductor-jet pump, a water eductor or an aspirator. An ejector operates on similar principles to create a vacuum feed connection for braking systems etc.

  7. Liquid-ring pump - Wikipedia

    en.wikipedia.org/wiki/Liquid-ring_pump

    Single-stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 47 millibars (4.7 kPa), and two-stage pumps can produce vacuum to 25 torr, assuming air is being pumped and the ring-liquid is water at 15 °C (59 °F) or less. Dry air and 15 °C sealant-water temperature is the standard performance basis, which most manufacturers use for ...
