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.

Airlift pumps have been used for sample collection of seawater (Tokar et al., 1981) as well as water circulation and aeration in aquaculture ponds (Parker and Suttle, 1987;Wurts et al, 1994).

Airlift pumps, 185 cm long, were made from PVC pipe of 7.6, 10.2 and 15.2 cm inner diameters. Air was injected through a 2.5-cm pipe at 50, 65, and 80 cm below the water discharge outlet. Water.
HOW AIR LIFT PUMPS WORK YouTube
Air lift pumps are finding increasing use where pump reliability and low maintenance are required, and where corrosive, abrasive, or radioactive fluids must be handled. Although air lifts are used in nuclear fuel reprocessing plants, no general, theoretically sound equation has been proposed in the literature for tall air lift design.

This paper aims in developing a new model, referred to as the integral model, which uses a combination of a first principal approach and experimental correlations. This model can address two basic airlift design problems: Calculation of the water pumping rate for a given air flow rate, and,

This airlift is pumping about 900 liter/hour from an IBC tank to a height of 1.8 meters to a clarifier. The vertical 3-inch PVC pipe is fed water by a 'T' connection to the IBC tank (Figure 3). This 3 inch pipe has a cap on the bottom and serves as a kind of 'sump well' for the actual 'pipe-in-a-pipe' pump.

DIY Airlift Pump Design Using Plastic Pipe and Air Compressor To start, you will need to remove the well cap. If damaged, build or buy a new one. Keep the well clean. Put four holes in the well cap. (Illustration 1.) Two holes for vents, one for the 1 ¼" discharge pipe, and one for the ½ air pipe. Screen the vents.

An air-lift pump is a device which is used to lift water from a well or a sump with the use of compressed air. The compressed air is made to mix with the water. It is well known that the density of water is more than the density of air.
FloMov Airlift Pumps FloNergia
Airlift pumps use compressed gas to verticall transport liquids and slurries. Due to the lack of theoretical equations for designing and predicting flow regimes, experimental investigations must be carried out to find the best condition to operate an airlift pump at high efficiency.

Several investigators have reported the flow rates of small-diameter airlift pumps used to lift water vertically. Spotte (1970) presented data on the vertical lift capacity of airlift "pumps 2.5-15 cm in diameter and 40-70% submerged. Spotte (1979) revised the water flow rates from his earlier edition and also included flow rates of air.

The air-lift pump is a well-established method for vertical transport of liquids and solid-liquid mixtures. The objectives of the present study are to evaluate the performance of a pump under predetermined operating conditions and to optimize the related parameters for the use of the pump for two-phase mixtures of air and water when a compressor is readily available.
