  2. Foam pump - Wikipedia

    en.wikipedia.org/wiki/Foam_pump

    A foam pump. A foam pump, or squeeze foamer and dispensing device is a non-aerosol way of dispensing liquid materials. [1] The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The parts of the foam pump, mostly made from polypropylene (PP), are similar to those of other pump devices. The foaming pump often comes ...

  3. Pneumatic trough - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_trough

    Pneumatic trough, and other equipment, used by Joseph Priestley. The bottle is filled with water, inverted, and placed into the pneumatic trough already containing water. The outlet tube from the gas-generating apparatus is inserted into the opening of the bottle so that gas can bubble up through it, displacing the water within. [4]

  4. Pump dispenser - Wikipedia

    en.wikipedia.org/wiki/Pump_dispenser

    Refillable bottle with pump dispenser for liquid soap. A pump dispenser is used on containers of liquids to help dispensing. They might be used on bottles, jars, or tubes. Often the contents are viscous liquids such as creams and lotions. [1] Some are metered to provide uniform usage. Some mix contents from two or more sources prior to dispensing.

  5. Water dispenser - Wikipedia

    en.wikipedia.org/wiki/Water_dispenser

    A freestanding design generally involves bottles of water placed spout-down into the dispensing machine. Tabletop or kitchen worktop versions are available which utilize readily available five-liter water bottles from supermarkets. These coolers use air pumps to push the water into the cooling chamber and Peltier devices to chill the water.

  6. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    Hand-powered force pump, with an air chamber to smooth out variations in flow rate. Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities.

  7. Air-operated valve - Wikipedia

    en.wikipedia.org/wiki/Air-operated_valve

    An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate.

  8. Spray nozzle - Wikipedia

    en.wikipedia.org/wiki/Spray_nozzle

    This type of spray nozzle may require more atomizing air and a higher atomizing air pressure drop because the mixing and atomization of liquid takes place outside the nozzle. The liquid pressure drop is lower for this type of nozzle, sometimes drawing liquid into the nozzle due to the suction caused by the atomizing air nozzles (siphon nozzle).

  9. Pneumatic chemistry - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_chemistry

    Robert Boyle's air pump. In the history of science, pneumatic chemistry is an area of scientific research of the seventeenth, eighteenth, and early nineteenth centuries. . Important goals of this work were the understanding of the physical properties of gases and how they relate to chemical reactions and, ultimately, the composition of
