2. Air pump - Wikipedia

   en.wikipedia.org/wiki/Air_pump

   Boyle's air pump. An air pump is a pump for pushing air. Examples include a bicycle pump, pumps that are used to aerate an aquarium or a pond via an airstone; a gas compressor used to power a pneumatic tool, air horn or pipe organ; a bellows used to encourage a fire; a vacuum cleaner and a vacuum pump. All air pumps contain a part that moves ...

3. Peristaltic pump - Wikipedia

   en.wikipedia.org/wiki/Peristaltic_pump

   This class of pump is often called a "hose pump". The biggest advantage with the hose pumps over the roller pumps is the high operating pressure of up to 16 bar. With rollers, max pressure can arrive up to 12 bar (170 psi) without any problem. If the high operating pressure is not required, a tubing pump is a better option than a hose pump if ...

4. Doing It Right (scuba diving) - Wikipedia

   en.wikipedia.org/wiki/Doing_It_Right_(scuba_diving)

   The corrugated hose of the inflator assembly should be long enough to easily dump air from the bladder and no longer, as unnecessary length makes it difficult to streamline. [48] The inflator mechanism must not be a high flow type as these use a non-standard connector, and can fill the wing dangerously quickly if the valve sticks open.

5. Diver's pump - Wikipedia

   en.wikipedia.org/wiki/Diver's_pump

   Pistons attached to the crankshaft draw in air through the inlet valves and then pump it through the outlet valves to an air hose which delivers the air to the helmet of the diver. Cylinders, valves and outlet fittings for air are generally made from brass for corrosion resistance in the marine environment. Rotary operated pumps were ...

6. Air line - Wikipedia

   en.wikipedia.org/wiki/Air_line

   An air line is a tube, or hose, that contains and carries a compressed air supply. In industrial usage, this may be used to inflate car or bicycle tyres or power tools worked by compressed air, for breathing apparatus in hazardous environments and to operate many other pneumatic systems.

7. Buoyancy compensator (diving) - Wikipedia

   en.wikipedia.org/wiki/Buoyancy_compensator_(diving)

   A means of adding gas to the bladder, generally a low pressure direct feed [notes 1] or power inflator [notes 2] that injects gas from a low pressure hose from a diving cylinder's first stage regulator to the bladder of the BC, and usually an oral inflation option. Gas flow is controlled by a spring loaded, normally closed, manual operated ...
