Water supply is an important component of comfort. In a country house or at the dacha, you can use different water sources. One of the most ancient ways to get moisture is the arrangement of the well. This design is simple to perform and does not require special care. But in order to facilitate their work on the delivery of water from underground layers to the surface, it is desirable to install a pump. This unit will ensure the smooth operation of the water supply system. But which submersible pump is best suited for wells? This will be discussed in this article.

What is the difference between well and well pump?

For water supply of a private house, when it is necessary to raise water from the depths can be used different types of pumps. Having come to the store, you can choose the submersible or deep, semi-submersible or surface type of unit. But the first option is most popular. Such designs are easy to use and quite reliable.

But, besides the above, the seller will ask - what kind of submersible pump, well or well, do you need? In principle, there are no major differences between the two species. A well and well submersible pump may differ only in two parameters. Namely:

• By its size;
• According to the efficiency of engine cooling.

Most submersible well pumps fitted with a cooling jacket. As a result of this design feature, their diameter increases markedly. Devices for wells are cooled by pumping water. That is why there are certain minimum values ​​of the rate of flow of fluid through them.

Also, downhole units, according to manufacturers, should not work in a pipe whose diameter is too much larger than the cross section of the device itself. But most users do not hurt to trust the opinion of companies. Therefore, downhole submersible pump is considered quite suitable for use in the well. The only thing that can stop you is the price. As a rule, borehole pumps cost a little more than well-devices with similar performance.

For an autonomous water supply system, the water source of which is a well, various types of submersible pumps can be used. Having come to the store, you can buy:

• Centrifugal pumps;
• Vibration units;
• Whirling equipment;
• Screw machines.

The last two are extremely rare, so it makes no sense to consider them. Another thing is the device centrifugal and vibration type. That they can often be found at the cottages and country houses.

The most popular for water supply among the owners of private houses are centrifugal submersible pumps. In them, the movement of water occurs due to centrifugal force, which is created due to the rotation of the impeller. Centrifugal submersible pumps are distinguished by high productivity. But for “good work” it is necessary and worthy to pay, so these devices are expensive.

Vibration or vacuum pump works on a different principle. In them, suction occurs by creating a vacuum in the working chamber. The decrease in pressure occurs due to the movement of the armature, which rises and falls by switching on and off the electromagnet. There are a lot of such movements, so the water comes pretty quickly.

But still, the performance of vibration pumps is lower than that of their centrifugal counterparts. In addition, permanent anchor movements cause vibrationwhich is transmitted to the pipes. As a result, the well is gradually loosened. The advantage of this device is its low price and long service life.

What to look for when choosing?

A submersible pump for a well is an important component of your autonomous water supply system, so its choice must be made deliberately. And what should I pay attention in the first place? Here are some tips from experts:

• First of all, it is worth deciding in advance with the necessary power. This is done by experience. All water intake points located in the house and on the plot are taken. Further, it is analyzed how much water they consume at the same time. As a rule, for a small house equipped with all modern water-consuming devices, a submersible pump for wells with a capacity of 3-4 cubic meters per hour is enough. Do not save on power. By choosing a pump with a lower capacity, you will get less pressure at the most peak moment. A lack of water, for example, for a washing machine can cause it to break down;
• Another important parameter that influences the choice is the pressure head delivered by the deep well pump. This characteristic can be found in the passport of the product. The same washing machine may simply not work if the water pressure in the plumbing system is too low. Do not forget that the pressure generated by the device and the pressure in the valve (or other device) can be very different. Each bend of a water pipe reduces speed. And the lower the speed, the less pressure.
• The presence of an automatic shutdown system when the water level in the well drops. As a rule, submersible pumps are equipped with a float system. It works in the case of a water level below the critical level.

It is also worth noting that it is better to purchase devices from trusted manufacturers. So you reduce the risk of running into a defective pump.

But besides the submersible pump itself, it is worthwhile to take care of the purchase of some additional equipment. First, it is desirable install a hydroaccumulator in the house. Such a device will be able to collect water, as a result, your pump will turn on less frequently. The accumulator must be equipped with a special relay, which will control the start of the pump. Secondly, be sure to install a check valve in the outgoing hose. Such a device will save you from water hammer.

Of course, each unit for wells must be equipped with a filter. Such devices are designed for pumping clean water. Therefore, the unit itself and the filter must be periodically cleaned of deposits.

Pay attention to the power cable. He must be long enough. It is not advisable to connect several cables. It is always damp in the well, and it is rather difficult to make a sufficiently reliable isolation of the junction. As a result, there is a high risk of a short circuit, which can easily destroy the immersion device.

Some popular brands

Find a suitable and reliable submersible pump for your well, today there are no problems. Modern manufacturers offer a large selection of devices, differing both in their performance and price.

Among the most popular models Submersible pumps are the following:

• "Kid" - a small device with a democratic price. Such a pump easily provides water to a small country house. At the same time, the “baby” can be installed both in the well or the well, and in any reservoir;
• "Dzhileks Vodomet" - a more powerful device operating on the centrifugal principle. Such a pump can provide water from a well or well to a large country house, along with a garden plot. Depending on the power of "Dzhilix Vodomet" can be purchased in the range of 12 - 20 thousand rubles;
• Aquarius is another representative of the centrifugal family. Designed for use in decks or wells with a diameter of 110 mm. Such a device can be purchased in the range of 12 to 25 thousand rubles;
• Grundfos is a powerful and reliable unit used for pumping water from wells. Such a submersible pump is capable of delivering up to five cubic meters of water per hour. This amount is enough even for a small cottage village, not to mention one private house or summer cottage.

There are many other models from different manufacturers. Their cost, depending on the power, can vary. from 7-8 to 35 thousand rubles and more.

As a conclusion

Providing a country house with drinking water is one of the first tasks of the owner. A well can be used as a source of water. This simple and reliable structure perfectly copes with its task. But for uninterrupted water supply it is necessary to use pumps, and immersion devices are the best option. You can choose different types and models of similar units, but in any case they will work smooth and long.
