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.
The airlift pump – also called mammoth pump – exploits the increase of the oxygen intake in water under pressure. At the same time, rising air is used to lift – and therefore circulate – water. This makes the mammoth pump suitable for aerating and circulating large volumes of water.
Air Lift Pump. The principle of an air lift pump is to pump water with solids which tend to block and wear out pump wheels of wastewater pumps. In a tube (which is also called riser) is compressed air released (airbubbles like in a whirlpool) on the bottom.
The ‘pipe-in-a-pipe’ airlift pump takes advantage of the fact that air injected underwater will expand as bubbles as it rises to the surface, with a 10% increase in volume from a depth of 1 meter.
Sep 1, 2015 · The present airlift pump utilizes various air injectors specially designed to enable air injection radially, axially, dual (radial and axial), or with a swirl effect at the air inlet ports.
Have you ever wondered how air can lift water and pump it from deep wells? How intermittent availability of electricity does not interfere with the operation of these air-lift pumps? Read here to learn about the air-lift pumps and their working principle. Know the advantages and disadvantages of air-lift pumps.
The foremost strength of an airlift pump is its simplicity. No moving parts imply no damage, no critical maintenance, no special inventory requirements and almost nil overhauling costs. Reliability is high and failure probability is low. Only driving 'force' required is compressed air.
