   Around 1908, the first mechanical aquarium air pump was invented, powered by running water, instead of electricity. [30] The introduction of the air pump into the hobby is considered by several historians of the hobby to be a pivotal moment in its development.

   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 ...

4. Protein skimmer - Wikipedia

   en.wikipedia.org/wiki/Protein_skimmer

   Air stone protein skimmers require powerful air pumps which are often power hungry, loud, and hot, leading to an increase in the aquarium water temperatures. While this method has been around for many years, due to more efficient technologies emerging, many regard it as inefficient current uses in larger systems or systems with large bio-loads.

5. Airlift pump - Wikipedia

   9. air liquid mixture 10. pump outlet L: liquid, usually wastewater LL: liquid level V: Vessel G: Gravel or solids. An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at the bottom of the discharge pipe which is immersed in the liquid.

6. Aquarium filter - Wikipedia

   en.wikipedia.org/wiki/Aquarium_filter

   The pump should only be powerful enough to push the water through the filtering material as well as overcome the drag in the intake and return pipes. This makes canister filter pumps virtually insensitive to the height difference between the aquarium and the filter (although exceeding the manufacturer-specified height limit can lead to leaks).

7. Pump - Wikipedia

   Typically run on electricity compressed air, diaphragm pumps are relatively inexpensive and can perform a wide variety of duties, from pumping air into an aquarium, to liquids through a filter press. Double-diaphragm pumps can handle viscous fluids and abrasive materials with a gentle pumping process ideal for transporting shear-sensitive media.
