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 .
Conventional airlift pumps have a flow rate that is very limited. The pump is either on or off. It is very difficult to get a wide range of proportional flow control by varying the volume of compressed air. This is a dramatic disadvantage in some parts of a small wastewater treatment plant, such as the aerator. [5] the suction is limited.
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.

Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air ...
Fine bubble aeration is an efficient technique of aeration in terms of oxygen transfer due to the large collective surface area of its bubbles. Fine bubble aeration is an efficient way to transfer oxygen to a water body. [8] A compressor on shore pumps air through a hose, which is connected to an underwater aeration unit.
In aeration air is pumped through an air stone or similar device that creates small bubbles in the water column, this results in a high surface area where oxygen can dissolve into the water. In general due to slow gas dissolution rates and the high air pressure needed to create small bubbles this method is considered inefficient and the water ...
