2. 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.

3. Pneumatic tool - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_tool

   Drilling a blast hole with a pneumatic drill (jackhammer). A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2) stored in small cylinders allowing for portability. [1]

4. Air flow bench - Wikipedia

   en.wikipedia.org/wiki/Air_flow_bench

   The test piece is attached in series with the pump and measuring element and air is pumped through the whole system. Therefore, all the air passing through the metering element also passes through the test piece. Because the volumetric flow rate through the metering element is known and the flow through the test piece is the same, it is also known.

5. 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.

6. Actuator - Wikipedia

   en.wikipedia.org/wiki/Actuator

   Pneumatic actuator operating a valve through a rack-and-pinion mechanism. [7] A pneumatic actuator is similar to a hydraulic one but uses a gas (usually air) instead of a liquid. [8] [9] Compared to hydraulic actuators, pneumatic ones are less complicated because they do not need pipes for the return and recycling of the working fluid. On the ...

7. Metering pump - Wikipedia

   en.wikipedia.org/wiki/Metering_pump

   Although metering pumps can pump water, they are often used to pump chemicals, solutions, or other liquids. Many metering pumps are rated to be able to pump into a high discharge pressure. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of discharge (outlet) pressure.
