  2. 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 ...

  3. Maple syrup - Wikipedia

    en.wikipedia.org/wiki/Maple_syrup

    A sugar maple tree. Three species of maple trees are predominantly used to produce maple syrup: the sugar maple (Acer saccharum), [5] [6] the black maple (), [5] [7] and the red maple (), [5] [8] because of the high sugar content (roughly two to five per cent) in the sap of these species. [9]

  4. Sorption pump - Wikipedia

    en.wikipedia.org/wiki/Sorption_pump

    The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen. The ultimate pressure is about 10 −2 mbar. With special techniques this can be lowered till 10 −7 mbar.

  5. Vacuum filler - Wikipedia

    en.wikipedia.org/wiki/Vacuum_filler

    The vacuum system is enhanced with an additional vacuum pump, specially designed for the hopper. The hopper is closed and is connected to an upstream reservoir. The vacuum present in the hopper allows filling product to be drawn into the filling machine from the reservoir. The filling product is also intensively evacuated.

  6. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    A vacuum ejector, or simply ejector 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.

  7. Vacuum pump - Wikipedia

    en.wikipedia.org/wiki/Vacuum_pump

    In the field of oil regeneration and re-refining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification. [44] A vacuum may be used to power, or provide assistance to mechanical devices. In hybrid and diesel engine motor vehicles, a pump fitted on the engine (usually on the camshaft) is used to produce a vacuum.

  8. Peristaltic pump - Wikipedia

    en.wikipedia.org/wiki/Peristaltic_pump

    A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.

  9. Getter - Wikipedia

    en.wikipedia.org/wiki/Getter

    A vacuum is initially created by connecting a container to a vacuum pump. After achieving a sufficient vacuum, the container can be sealed, or the vacuum pump can be left running. Getters are especially important in sealed systems, such as vacuum tubes, including cathode-ray tubes (CRTs), vacuum insulating glass (or vacuum glass) [1] and vacuum ...
