Fundamentals/Wind-Driven Water
Air-Lift Pumps In a simple air-lift pumping system the wind-turbine drives an air
compressor which supplies an air-lift pump submerged in the well, or water
source. Since a simple air-lift pump does not contain any moving parts an
advantage is ...

Fundamentals of Aquacultural Engineering
An air lift pump uses a rising column of air to generate flow in a liquid system. The
most common type air lift consists of an open-ended tube or pipe that is partially
submerged in fluid into which air is injected (Figure 7-18). Air lift pumps operate ...

Handbook on Pressurized Irrigation Techniques
The main advantage of the air-lift pump is that there are no mechanical below-
ground components to wear out, so it is essentially simple, reliable, virtually
maintenance-free and can easily handle sandy or gritty water. The
disadvantages are ...

Biology and Culture of Channel Catfish
Paddlewheels, vertical pumps, and propeller-aspirator pumps can aerate a few
individual cages but usually do not work well in multiple-cage arrays. Air-lift pump
aeration works well for cages spaced along the sides of a pier. A regenerative ...

Environmental Engineering
Air-Lift Pump In an air-lift pump, compressed air is forced through a small air pipe
extending below the pumping water level in a well and discharged in a finely
diffused state in a larger (education) pipe. The air–water mixture in the eduction ...

Slurry Handling: Design of Solid-liquid Systems
4.4.4, Air-Lift Pump The air-lift pump (Fig. 1 3.9) is well-established for liquid
raising but only relatively recently has the pump principle been applied to
hoisting both settling and non- settling slurries. The pump is potentially useful for
the ...

Irrigation: Theory and Practice
The energy that is available to operate the air-lift pump is that which is contained
in the compressed air. The well casing itself can be used for the eductor pipe if
the diameter of the casing is not much larger than the air line. This provides a ...

So, air-lift pump is an ideal device to lift and transport the solid particles under
water for its simple structure, good wear resistance, reliable running, high safety
and high dredging depth. Air-lift pump has been utilized to transport slurries in ...

Practices of Irrigation & On-farm Water Management: Volume 2
The head which can be produced depends on the depth of submergence of the
air tube. Fig. 12.5 Schematic of air lift pump Discharge Pump Water level Air-lift
pumps are relatively inefficient. Typical efficiencies range between 30 and 50%.
