In the absence of a central water supply, providing your private house or summer cottage with water is not as difficult as it might seem at first glance, especially if there is already a well or a well. For this, special equipment is used — a submersible pump, with which you can raise water from the earth to the surface. This device is immersed below the level of the pumped water. It has high power and good performance. In addition, the submersible pump has small overall dimensions, it is placed in a special casing that can perfectly resist the occurrence of corrosion processes. These products are not very loud. The most common designs today are well, borehole and drainage pumps.
In specialized stores, the choice of this equipment is quite large. So that you do not get confused in the variety of the presented assortment, we decided to write our review regarding submersible pumps. However, before proceeding to a direct analysis of the useful characteristics of the models, we will give a few key points that you should pay attention to when choosing this product. So let’s get started.
What characteristics are important when buying a submersible pump?
In order for the acquired design to be optimal, the following factors must be taken into account: the quality of the well or well, as well as the requirements for the volume of water.
In the first case, one of the most important points is the depth from the surface of the earth to the bottom of the well or well. You can measure it yourself by tying a heavy load to the cord, or look at the technical documentation. However, the fact plays a role here that over time, the depth of the well will become less and less due to the silt accumulating there. It should be borne in mind that the pump must be located in such a way that it does not come closer than one meter to the bottom filter. Despite the fact that many manufacturers claim that their products can work even at a distance of only 40 cm, it is advisable to adhere to this rule.
The diameter of the well is also quite important, since it will directly affect the overall dimensions of the pump. The fact is that individual devices will fit in a well, the diameter of which will be 150 mm, others are designed for 130 mm. The productivity of a well or well allows not only to choose the most suitable pump in terms of water distribution, but also to determine how much water can be safely pumped out per unit of time. It is worth noting that the height of the water column can vary significantly depending on the season, the amount of water taken, and some other factors.
In terms of the pump itself, it is necessary to choose equipment that allows you to achieve good pressure even at the highest water flow. For this, the parameters of the average daily water consumption are taken into account. For example, according to current regulations, one person needs about 200 liters per day (in fact, this is about half as much). Accordingly, a family of 4 can spend about 0.8 cubic meters per day.
On sale you can find several types of pumps — vibration, centrifugal, vortex and screw. Most often, the first two varieties are used. However, it should be borne in mind that a vibration pump is not suitable for a well, as it will create a movement of water masses, begin to lift silt from the bottom, which will contribute to the rapid clogging of both the pump itself and the well. The design is quite simple and reliable, but quite noisy.
Centrifugal pumps are characterized by high performance and long service life. Water flows through them quite smoothly and evenly. However, such devices are very sensitive to contaminated water, and the pressure at the outlet is also not very strong.
Vortex pumps are more sensitive to the amount of impurities contained in the water compared to centrifugal designs, but at the same time they are able to provide a very strong pressure. For this reason, they are regularly used to create an irrigation system in their summer cottage. Vortex models are not used very often, as they wear out very quickly, begin to require repair, and so on.
When developing our 2020 rating and deciding which models to include in it, we were guided primarily by user reviews, and also looked at the value for money of the product. The most expensive designs were not included in the review, since we expected that such equipment would be affordable for each user. Now is the time to move on to reviewing the best submersible pumps of this year that can only be found on sale.

2. JILEX Water cannon PROF 55/50 A
Equipped with a mechanical float switch. This model is characterized by high productivity, which can reach almost 3.5 cubic meters of water per hour, while creating a head of up to 50 meters. The body diameter is only 98 mm, so the structure can also be installed in wells. The pump can be used to create automatic water supply systems. The impeller is floating, so the product can pump even rather dirty water, in which the sand content reaches 2 kg per cubic meter. The kit comes with a capacitor and a cable. A thermal relay is connected directly to the engine, capable of turning off the device if there is a lack or complete absence of water in the well. There are special drainage channels that will reduce the load on the electric motor during start and stop.
The manufacturer says that a check valve should be installed directly on the pump. If this possibility is not provided, then this should be done at a distance of no more than 7 meters from the device. In order for the float switch to function correctly, a certain amount of free space is required — 50×50 cm. In addition, the pump should not be immersed too deep in the water column — no more than 30 meters from its surface, nor should it be too close to the bottom: you need to keep a distance though by 20 cm. If power surges are observed in the power supply system, then it is necessary to connect to the network through a stabilizer.
Advantages:
- Differs in the lowest cost;
- Works effectively;
- Long period of operation;

It does not weigh much — the mass of the product is only a little more than 5 kg. The power cord has a length of 10 m, it has a Velcro ring, which increases ease of use. The connecting hose has a high level of strength, besides it is reinforced. If necessary, it can be removed from the pump and rinsed from accumulated contaminants. The clip that connects it to the body of the device is very massive and looks reliable. It is worth noting that the pump is able to function both in manual and automatic mode. The float cord is fixed on the body with a special slot. Its length is fixed so that when the water level in the well or container decreases, the float is at an angle of 45 to 0 degrees relative to its plane. This will allow the automation to work and stop the motor from working.
When using the manual mode, the float is placed in a special nest in the above-water part of the product, and is also closed with a special cover. The device is IPX8 rated, which allows the device to withstand complete and prolonged immersion in water to a depth of one and a half meters. The pressure is about 8 meters, the performance is also quite high, although lower compared to some other models — about 0.5 cubic meters, and this parameter can be adjusted if necessary. The bottom part of the motor is equipped with a special foam rubber filter, due to which all kinds of contaminants will linger on it and not penetrate under the body. If necessary, this filter can be removed and washed.
Advantages:
- Universal drainage design;
