2. 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.

3. 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.

4. 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 ...

5. 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.

6. Maple syrup - Wikipedia

   en.wikipedia.org/wiki/Maple_syrup

   Producers developed reverse-osmosis machines to take a portion of water out of the sap before it was boiled, increasing processing efficiency. [21] Improvements in tubing and vacuum pumps, new filtering techniques, "supercharged" preheaters, and better storage containers have since been developed.

7. Sugar bush - Wikipedia

   Sugar bush refers to a forest stand of maple trees which is utilized for maple syrup. This was originally an Indigenous camp set up for several weeks each spring, beginning when the ice began to melt and ending when the tree buds began to open. [1] At a traditional sugarbush, all the trees were hand tapped and the sap was boiled over wood fires.
