A air lift pump comes in different makes and sizes, and you buy the tool depending on the application. The pump used by a filling station is not the one you use to fill up your tanks. There are high flow rate low pressure systems used to transfer fluids axially. On the other hand, you can go with radial ones dealing with a low flow rate and high-pressure fluid. The mixed flow pump variety combines radial and axial transfer mechanisms and works with medium flow and pressure fluids. Depending on what it will be pumping, you can then choose the air lift pump of choice from the collection at Alibaba.com.

The pumps PM are made of corrosion-proof materials conforming to conditions for conveying potable water (GENOVA system). During air flow cut-off the pump’s construction provides separation of the supply system from the media pumping zone by means of a diaphgram perforated valve, closed by hydrostatic pressure.

The pumps are highly reliable and easy to assemble owing to the use of PVC hose as an intake end. The hose can be formed depending on the shape of the tank.

The capasities of the pumps (specyfied in laboratory conditions for clean water and constant depth Hz=1,5 m) are presented in the diagram showing the dependance of air demand supplied to the pump on the lifting height “H” of the medium being pumped (see data sent by fax).

The capasity of PM 110, at immersion depth Hz= 4m, is 15-20m3 (at H=0,5 m). The pumps can operate in a complex system allowing for multiplication of capasity. The lenghts of ends, intake L2 and exhaust L1, and air supply hose are specyfied by the buyer. We suggest the purchase of the very “heart” for individual assembly.

By Clifford E. Jones – There is no reason to pay a lot of money for a water pump when this DIY airlift pump design will do all you want. The cost is very low. The materials list is for a 100-foot well; adjust this to meet your well depth.

Now put the 1-1/4” clamp on top of the well cap. This will eventually keep the pump from dropping down the well, so make it tight and be sure it won’t slip down the hole in the well cap. Next, make the ½” line. Starting at the bottom, put on two 90 degree elbows and a 30” piece of pipe and insert it up into the 1-1-4” pipe and clamp both pipes together (Illustration 3).

What is happening here is air is pumped down the small pipe and released into the larger pipe forming bubbles which rise and capture the water and bring it to the top.

This article wouldn’t be complete without something on the air compressor. The main effort is to put some air down the small line that is only blocked by water. Any compressor capable of pumping up an auto tire will do. Air volume is more important than great pressure. I used an automobile air conditioner pump with great success but it did pump oil, and that isn’t good. Get yourself a good air compressor.

This airlift pump design may seem like a poor man’s pump, but there are some advantages over other pumps. It won’t freeze; you can do it yourself; any servicing is done at the compressor and not down the well; and if you just happen to live past the power company, you can still have the water and not cost you an arm and a leg.

According to relevant research, it is clear that for a traditional mud pump, there will be blockage and wear during the dredging process because the flow cross-section of the blade is so large that its concentration is limited. Compressed air serves as the power source for air transportation, which can pump and transport liquid or mud through the combination of buoyancy, friction, and vacuum effects (Fu and Yan, 2004; Pei and Liao, 2010). To the best of our knowledge, the airlift system has many advantages, such as low cost, easy operation, simple configuration, no pollution to the environment, and less blockage (Chen et al., 2009; Pei and Tang, 2015). Therefore, it can be considered that the air transportation system has great potential for river and lake dredging.

Many scholars have carried out research, such as numerical simulation of the mixed fluid in the airlift system and analysis of the relationship between the injection parameter and the performance so that it has a higher matching, and thus, the performance of mud airlift is improved. Huang et al. (2017) performed a numerical simulation to study the effect of the nozzle type, injection depth, and injection hole diameter on the airlift pump, thereby improving the performance of the airlift pump. Alasadi and Habeeb (2017) then performed a numerical simulation study on the airlift pump with traditional and improved air injection devices under different intake flow rates, and the results show that the airlift pump with an improved air injection device can improve performance at higher intake flow rates. In actual operation, sufficient attention should be paid to the critical point of the solid particles carried in the bottom layer. If this is not given, it will cause blockage in the pump which will affect the performance and cause safety accidents in severe cases. When researchers study critical characteristics, they are mainly conducted from the perspective of experiments and rarely involve theoretical models. Taleb and Al-Jarrah (2017) performed an experiment to study the effect of the submergence ratio and air injection hole diameter on the performance of the airlift pump. The results showed that the performance of the airlift pump increased as the submergence ratio increased, while an injection hole diameter of 4 mm gave the highest performance. Oueslati A performed an experiment under many operating conditions, and proposed a theoretical model taking into account the air humidification and liquid temperature. The results showed that the proposed model is in good agreement with the experimental results. Fujimoto and Murakami studied the critical conditions of a mud airlift pump and obtained a model of the critical water flow rate for lifting solid particles at the bottom of the pump. By using this model, results that are consistent with reality can be obtained (Fujimoto et al., 2004). On this basis, our research team expanded the suction distance and obtained the rule of critical particle detonation. It needs to be clear that the aforementioned studies are only for water–solid two-phase flow (Tang et al., 2012). Fujimoto and Nagatani then used the aforementioned working conditions to analyze the critical conditions of particles transported in the three-phase flow. The research results show that in the three-phase flow, the starting of particles is easier, but the corresponding theoretical model is not proved (Fujimoto et al., 2005). In application, because of the constraint pressure (Pei et al., 2010; Hu et al., 2013), the particles are often compressed when they are deposited at the bottom, which makes it difficult to start the particles. At the same time, the airlift is caused to fail, but scholars rarely conduct research on this aspect.

In this study, the research is carried out. The interface selects the inlet of the airlift pump to divide the mixed water into two fluid phases, one is a water–solid two-phase flow, and the other is a gas–water–solid three-phase flow. To satisfy the actual dredging, the medium used in this study is round river sand. Based on this, the critical conditions of the three-phase flow and two-phase flow are analyzed, and the relationship between the key condition and chip compaction is analyzed. For discussion, the research result of this study can provide a reference for other researchers to study related theories.

Analyzing Figure 3, it is clear that when JG,cri is increased, JL,3,cri will be reduced. After reaching the inflection point, JL,3,cri will decrease as JG,cri decreases. Therefore, by increasing JG,cri, the density of the mixed fluid can be reduced, so that the start of the particles becomes easier. Near the inflection point, because the gas value is large, the movement of the particles is mainly controlled by the water phase. From this, it can be clear that the performance of the airlift will be affected by working conditions, and it is necessary to reduce the air mass and then change the flow pattern in the tube, so that it can change from circular flow to elastic flow. It needs to be clear that this change is irreversible, that is, after reaching the inflection point, JL,3,cri will decrease with the decrease of JG,cri. According to the related research results (Hanafizadeh et al., 2011; Tang et al., 2016), the critical airlift of mud is opposite to the existence of the inflection point. In engineering applications, the inflection point needs to be moved down as much as possible. Comparing and analyzing the critical strength of particles with different diameters can be clear (Figure 3A). When the particle diameter is increased, JL,LS,cri and JL,3,cri will rise accordingly. The reason for this phenomenon is that increasing the particle diameter will increase the solid phase slip. In Figure 3B, it is clear that when the particle density increases, JL,LS,cri and JL,3,cri will rise accordingly. The reason for this phenomenon is that increasing the average density of the mixed water will reduce buoyancy. In addition, when increasing the particle density and diameter, the inflection point will move to the right (Kassab et al., 2007).

In the aforementioned model, particles need to be placed in the tube. However, in practical application, the particles will first deposit at the bottom of the water, and then they will be affected by the static chip retention effect. Obviously, the working conditions are different from those assumed by previous research. To be consistent with the practical situation, the research object selected in this study is particle B which is closest to the bottom of the pump. Figure 4 shows the force acting on particle B.

Compared with the critical water flow model[30] we constructed, it is clear that in this model, we only consider the static chip retention force (static chip retention effect) of the particles, which is in line with the actual engineering. Using the relevant parameters shown in Table 2 to calculate, the results of the model can be clarified (Figure 5). It is clear that with the increase of particle diameter dS and density ρS, the JL,LS,cri only shows a slight upward. On the contrary, when the immersion rate γ is continuously increased, JL,LS,cri will be significantly increased. If the particle density and size are smaller, then the immersion rate γ will control the start of the particle. Analyzing Figure 5, it can be clear that if the static chip retention effect is maintained, JL,LS,cri will be increased quickly. It is concluded that for small and medium particles, the airlift performance will be affected by the static chip retention effect.

It can be considered that in areas such as oceans and lakes, because of their greater depth, the particles have a larger static chip retention force, which causes the start to fail. If the particles are compacted, then it will prevent airlift dredging. Therefore, it is necessary to impact the sand layer before airlift, so that the static chip retention effect can be reduced.

Comparing the experimental results and the calculated results, it is clear (as shown in Figure 7) that the experimental value of the critical water flow rate for lifting the solid is lower than that of the calculation result when only lifting the particles. This situation occurs because the tube and the pump will coalesce, expand, rupture, and re-aggregate. The bubbles will move periodically, causing mixed fluid instability along the axial direction when it rises. Ascending, its oscillation characteristic is ascending-descending-ascending, and compared with descending motion, the ascending motion is more intense. According to the results of other researchers and ours, it can be inferred (Hu et al., 2012; Hu et al., 2015) that the basic feature of a slurry airlift is the oscillating upward motion of the mixed fluid, which will cause a transient vacuum, so there will be resistance. If the particle’s fluctuation reaches its peak, then the particle’s activation state can be advanced. Figure 7 also shows that if the immersion rate is lower, the mixed fluid will have more prominent oscillation characteristics, which will result in a higher instantaneous vacuum. To confirm these phenomena, high-speed cameras can be used.

Due to the effect of gravity, the particles will be affected by the static chip retention effect when they are deposited at the bottom of the water. When we are conducting research, we put sand particles on the bottom of the pump in advance (Figure 4). At this time, the sand will be closely arranged and in a double-stacked state. To maintain the static chip retention effect, the particles need to be placed in the water continuously for 7 days. Then we adjusted the water tank and preset the immersion rate. The particles in the center of the upper layer are the object, and the key experimental steps are repeated. Based on this, we can get JG, L, LS, Cri, JG, S, LS, Cri, and JL, LS, Cri. The research results show that the particles cannot start when the air compressor valve is adjusted from close to the maximum gas flow. Therefore, it can be considered that the static chip retention effect is obvious at the bottom. Even if the pump has a large water value and the resistance imposed on the particles is small, the static chip retention force cannot be overcome, thus making it impossible to carry out an airlift. To clarify the experimental results of JL,LS,Cri, we connected the outlet of the airlift pump to a high-power centrifugal pump. Table 4 shows the comparison results of theoretical and experimental critical values. Research on the table can be clear, and the calculation results show that the experimental results of JL,LS,Cri are low. Therefore, it can be considered that the fluctuation of water flow and surface defects between adjacent particles (Figure 4) will reduce the compactness, which finally weakens the static retention effect of the chips. Therefore, it can be considered that as long as the static chip retention effect exists, it will affect air transportation, so it is necessary to take measures to eliminate it.

2) In a water-solid two-phase flow, the physical properties of the water and particles will affect the critical water rate. However, in the gas–water–solid three-phase flow, not only will the physical properties of water and particles affect the critical water rate but so will the air rate. Before the inflection point, as the air critical flow increases, the water flow will decrease. After the inflection point, as the air critical flow increases, the water flow will increase. In addition, the existence of the inflection point is not conducive to airlift.

4) When there is a static chip retention effect under water, it is necessary to use auxiliary methods to impact the particle layer or to increase the resistance of the particles, otherwise, it will not be conducive to airlift.

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 compressed air mixes with the liquid causing the air-water mixture to be less dense than the rest of the liquid around it and therefore is displaced upwards through the discharge pipe by the surrounding liquid of higher density. Solids may be entrained in the flow and if small enough to fit through the pipe, will be discharged with the rest of the flow at a shallower depth or above the surface. Airlift pumps are widely used in aquaculture to pump, circulate and aerate water in closed, recirculating systems and ponds. Other applications include dredging, underwater archaeology, salvage operations and collection of scientific specimens.

Airlift pumps are often used in deep dirty wells where sand would quickly abrade mechanical parts. (The compressor is on the surface and no mechanical parts are needed in the well). However airlift wells must be much deeper than the water table to allow for submergence. Air is generally pumped at least as deep under the water as the water is to be lifted. (If the water table is 50 ft below, the air should be pumped 100 feet deep). It is also sometimes used in part of the process on a wastewater treatment plant if a small head is required (typically around 1 foot head).

The liquid is not in contact with any mechanical elements. Therefore, neither the pump can be abraded (which is important for sandwater wells), nor the contents in the pipe (which is important for archeological research in the sea).

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.

this pumping system is suitable only if the head is relatively low. If one wants to obtain a high head, one has to choose a conventional pumping system.

A recent (2007) variant called the "geyser pump" can pump with greater suction and less air. It also pumps proportionally to the air flow, permitting use in processes that require varying controlled flows. It arranges to store up the air, and release it in large bubbles that seal to the lift pipe, raising slugs of fluid.

FloNergia"s FloMov family of pumps are designed specifically for Aquaculture, Aquaponics and Hydroponics applications. They offer a well-engineered dual injector airlift pump solution that uses significantly less energy than conventional centrifugal pumps.

With a wide range of ready available sizes, these pumps serve the need of producers large and small.  Custom design solutions are available for an even wider variety of applications and sizes.

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 density of the mix of air and water is lower as from water around therefore there is upstream flow. In this flow all the water from the bottom of the pipe is pumped to the top with a slightly suction power. Airlift pumps can be used for high flowrates on a less head. The head and the flowrate are depending on the flowrate of the compressed air, the tube diameter, the tube length. Typical application are sandy water lifting, abrasive materials. Also they are often  from wwtp- producers used in order to produce a robust pump for longer lasting guarantees
