Well pump: selection and installation

In many remote villages or settlements, the well is the main source of water. However, constantly extracting liquid manually is quite problematic, and when using a large depth structure it can be physically difficult. That is why professionals advise to install a well pump that can turn this construction into a real well and supply pressurized water directly to the home pipeline system.

Types and scope

First we need to say that there are many varieties of such products, which differ from each other in power, design and purpose. Moreover, all of them can be divided into two categories. The first involves the installation of the pump on the surface, and the second type should be immersed in water.

Basic concepts and common features

• First of all, it is necessary to understand that after installation, the well will begin to function as a well, and its walls will actually become a casing.
• Install a water supply system leading to the house you need under the ground, below the level of soil freezing. So the water in it will flow normally even in cold winters.

• It is necessary to select a well pump in accordance with the technical characteristics of the installation site and depth. At the same time, it is at this stage that the division into types and certain structural features occurs.
• It should be said that to install such devices only in order to raise water from the well is quite wasteful. It is necessary to immediately organize the connection to the water supply system at home and install all the necessary additions.

• When purchasing pumps of various types, you should immediately select the appropriate check valves, hydraulic accumulators and filters for them. In this case, special attention should be paid to the combined systems, which immediately combine all the necessary elements in themselves and are in fact ready-made nodes.
• The connection of these products is best done through a separate machine and equip the electric circuit of the AMS.

Tip! There are a number of specific requirements and regulations, the implementation of which will increase the life of the pumps. That is why it is necessary to study in detail the technical characteristics and instructions for each individual model.

Surface pumps

• These types of products are used in wells of shallow depth. Usually it does not exceed 15 meters, but some masters recommend installing such pumps only up to 10 meters. This is done in order not to overload the system and increase the service life.
• Most manufacturers supply surface well pump with a special plate on which they indicate the working depth. At the same time, it is worth purchasing units with slightly overestimated readings in order not to overload the device and prevent it from operating at full capacity.

• It is worth noting that many surface pumps are immediately equipped with hydroaccumulators. They are needed in order to maintain the pressure in the system even after a power outage. This significantly reduces the number of short-term start-ups, which are accompanied by the supply of high currents to the primary winding of the engine, and therefore, prolong the service life of the device.
• Special attention is also paid to check valves. Their purpose is to prevent water hammer. However, not all pumping units are completed with such parts, and they have to be purchased separately.

• Install these units is in the immediate vicinity of the well. For them create separate extensions that can protect from cold weather or precipitation.
• In the well itself immerse the hose, which at the end is equipped with a special filter. In addition, for some models such a system is supplied, and for others it is necessary to create it yourself.

• It is necessary to mention portable surface pumps. They work as autonomous stations and can be connected to any sources, including wells. However, the instruction manual for such devices has certain limitations, which means that they should be purchased for specific conditions.
• Portable pumping units are most often used by summer residents, arriving only for the summer period of time. After that, the structure is simply dismantled and transferred to the house. It should be said that the connection of such devices does not take much time and in almost half an hour you can get a working plumbing system.

Tip! If the house is located near the well, the surface pump can be installed indoors. However, its power should be selected along the length of the water hose.

Submersible pumps

• Devices of this type are great for deep wells. It should be noted that the submersible well pumps by their principle of operation is very similar to the products that are used for wells.
• Such constructions can be immediately equipped with a filter or have fastenings for its installation. They also need to install a check valve and only after that they are fixed on the water hose or pipe.

• Special attention should be paid to the fact that these systems are equipped with a special seat for fastening the cable. It is necessary in order to lower and reach the pump. Given this, this element must be selected very carefully, based on the conditions of its operation.
• The choice of power of the unit is determined in accordance with the depth of the well and the required pressure in the system. Also professional masters recommend using products of this type together with a pressure switch and a hydraulic accumulator. At the same time, these devices are already installed in the house.

• It is necessary to say that the price of such devices for water supply consists of the totality of the cost of all elements of the system. The fact is that without additional elements the pump itself cannot fully function. That is why, when planning what type of unit is best used, it is worthwhile to realistically assess the expediency of using deep types and take into account all additional costs.
• It is worth mentioning that there are pumps of this type for shallow wells. They have a low cost, but have low productivity. However, most of these models are not designed for continuous use and have a small lifespan.

• Among the products of this type there are such models that are immersed to a depth, and water is taken from the surface. For these purposes, they use special floats, which are fixed at the end of a flexible pipe connected to the water intake part. Such structures are used in cases where the bottom of the source is heavily silted and it is best to take liquid from the surface.

Tip! Submersible systems should be chosen only during continuous operation. Otherwise, they quickly become unusable.

Recommendations of the masters

• If the work is done by hand, then professional craftsmen recommend that you first thoroughly familiarize yourself with the technical characteristics of the selected device and clarify the methods of its installation. Otherwise, you can damage the pump or get a large energy overrun that could have been avoided.
• Do not lower the water inlet or submersible unit to the very bottom of the structure. So the product will tighten the silt and sand, which very quickly clog the filter. It is necessary to immerse the device on the bottom, and then raise it by one meter.

• It must be remembered that devices with a float usually operate in a completely autonomous mode and are intended for pumping water into a specific reservoir. If the liquid level drops, such a pump will not work, which means that such an option must be considered when choosing a design oriented to a specific source.
• The most important aspect in determining the required type of product is the degree of filling of the well. It is necessary to determine the level of water from the bottom to its beginning and try to scoop it all up. If this fails, then you can use almost any unit, but otherwise you should choose a specific device with a controller.

• If a new well is being produced, then it is worthwhile to immediately think up an automated system for the extraction of water from it. Otherwise, you will have to return to earthworks again.
• When all work is done independently, and there is no experience in selecting the required device and its installation, then you should consult a specialist who can advise a specific product and give useful recommendations on its installation.
• Not all well pumps are suitable for well operation and can break the system.

Conclusion

Watching the video in this article, you can get detailed information about the various types of data devices and their application. Also based on the text presented above, it should be concluded that there are a number of different pumps that are used to work with wells. They are designed for certain technical conditions, the main of which is considered to be the depth of the structure (see also the article Independent design of a well on a country site).

Given this, the well pump should be selected only after all the initial parameters have become known. They also include the number of residents in the house, the approximate water consumption and the frequency of use of large volumes, which is very important when choosing a hydroaccumulator.
