In the absence of central water supply, it is not as difficult to provide your private house or cottage with water as it might seem at first glance, especially if there is already a well or a well there. For this, special equipment is used - a submersible pump, with which you can raise water from the earth to the surface. This device is submerged below the level of pumped water. It has high power, good performance. In addition, the submersible pump has small overall dimensions, it is placed in a special housing that can excellently resist the occurrence of corrosion processes. Such products do not work very loudly. The most common designs today are well, well 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 present several key points that you should pay attention to when choosing this product. So let's get started.
Summary of the rating:
What characteristics are important when buying a submersible pump?
In order for the acquired design to be optimal, it is necessary to take into account the following factors: 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. It can be measured independently by tying a heavy load to the cord, or see the technical documentation. However, the fact that the depth of the well will become less and less due to the accumulated sludge plays a role here. It should be borne in mind that the pump should be positioned so that it does not approach a distance of less than one meter from the bottom filter. Despite the fact that many manufacturers claim that their products can work at a distance of only 40 cm, it is advisable to adhere to this rule.
The diameter of the well is also quite important, as 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 a well not only allows you to choose the most suitable pump in terms of water distribution, but also allows you to establish how much water can be safely pumped out per unit time. It is worth noting that the height of the water column can vary significantly depending on the time of year, the amount of water taken and some other factors.
In terms of the pump itself, it is necessary to choose equipment that allows even a high water flow rate to achieve a good pressure. To do this, take into account the parameters of the average daily water flow. For example, according to current regulations, about 200 liters are needed per person per day (in fact, this is about half as much).Accordingly, a family of 4 people can use 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 the vibration pump is not suitable for the well, since it will create a movement of water masses, it will start to lift sludge from the bottom, which will contribute to the rapid clogging of both the pump and the well. The design is quite simple and reliable, but quite noisy.
Centrifugal pumps are characterized by high performance and a long period of operation. Water is supplied through them quite smoothly and evenly. However, such devices are very sensitive to contaminated water; the outlet pressure is also not very strong.
Vortex pumps are more sensitive to the amount of impurities in the water compared to centrifugal structures, but they can provide a very high pressure. For this reason, they are regularly used to create an irrigation system in a summer cottage. Vortex models are not used too often, as they wear out very quickly, begin to require repair, and so on.
Developing our rating and deciding which models to include in it, we were guided, first of all, by user reviews, and also looked at the price-quality ratio of the product. The most expensive designs were not included in the review, since we hoped that each user could afford such equipment. Now is the time to move on to review the best submersible pumps this year, which can only be found on sale.
