There are many types of pumps on sale today. Devices of this type can have a different design and purpose. Domestic and foreign manufacturers produce pumps designed for water intake from natural or artificial reservoirs, narrow wells and, of course, wells. In the latter case, both surface and submersible models can be used. Deep well pumps, in comparison with conventional ones, have a lot of undeniable advantages.
Why choose a submersible model?
The advantages of pumps of this type can be attributed primarily:
Ease of use. In order for such an aggregate to start working, you just need to turn it on. Since it is located at a depth, filling it with water, unlike the surface, is not necessary.
Long service life. During operation, the engine of such a pump is constantly washed with cold water. Therefore, it never overheats.
Possibility of using the cleanest water in the house. On pumps of this type without fail special filters are installed that trap particles of dirt.
The disadvantages of equipment of this variety can be attributed only to some complexity of repair. Since it is impossible to prevent water from entering nodes that are energized, submersible pumps are produced in a sealed enclosure, which is rather difficult to disassemble. Also a minus of equipment of this type is the need for periodic replacement of cleaning filters.
Varieties
From the owners of suburban areas, one can often hear the question of which submersible pump is better for a well. At the moment, on sale you can find equipment of this type of several major groups:
vibrational;
centrifugal;
vortex;
screw.
The most popular are the first two varieties. It is vibrational and centrifugal submersible models that can most often be seen in the wells of domestic summer residents.
Vibration models
Well pumps of this type have been manufactured by industrial enterprises for quite some time. In Soviet times, the owners of summer cottages often used precisely such equipment for watering beds and garden trees. During operation, the vibration models hum and vibrate very much. Hence their name. The advantages of such equipment are primarily reliability. Also, the summer residents consider the plus of these models to be that they can be used even in long uncleaned wells. To the increased content of sand, clay, etc. particles in the water, they are completely insensitive.
A disadvantage of this type of equipment, in addition to noise in operation, is that when it is used, the source is very rapidly silted. When the pump vibrates, turbidity rises. A certain part of the unit can drive through itself. But very large particles are trapped by its filter and settle to the bottom. As a result, sludge is formed. Therefore, if you decide to purchase a vibration pump, be prepared for the fact that you will have to clean the well quite often.
Centrifugal pumps
This type of equipment is currently the most popular among summer residents and owners of country houses. Such pumps serve for a very long time and at the same time they have good performance. Unlike vibrational ones, they do not make noise during operation and do not raise turbidity. These models supply water very smoothly and evenly.
Some drawbacks of equipment such as a centrifugal submersible pump are that they cannot be used to pump contaminated water. Also, the minuses of such models include a not too strong pressure.
Vortex Submersible Pumps: Pros and Cons
Models of this group pump water due to the presence of a special wheel with blades in their design. Their main advantage is that they give a much greater pressure (three to nine times) in comparison with centrifugal ones. But unfortunately, according to many summer residents, they are very sensitive to the presence of pollution in the water. In this regard, vortex pumps are inferior even to centrifugal pumps. This explains their not very high popularity among the owners of suburban areas. If it is still possible to install such a pump in a drinking well, then it will not work for a long time in an artificial pond or ordinary digger. Do not use models of this type for pumping water from too deep sources.
Screw pumps
As already mentioned, these are not very popular pumps for wells. Submersible (which version of the equipment is best suited in a particular case, of course, to decide the owners of the suburban area) screw unit has one significant drawback, significantly reducing its popularity. The fact is that the moving elements of such pumps have a large number of points of contact. As a result, they wear out very quickly. And therefore, such a pump requires frequent repairs. Equipment of this type is usually used for pumping not any kind of water, but various kinds of viscous liquids.
Key selection criteria
Asking the question of which is the best submersible pump for a well, one should also decide on the specific parameters of this equipment. When choosing the most suitable model, among other things, you should pay attention to its characteristics such as:
Performance. Of course, any submersible pump must first of all fully provide a country house and green spaces with water. When choosing this equipment, it should be borne in mind that one person living in the house should have about 200 liters of water per day, and about five liters are needed to irrigate one square meter of beds.
The pressure. How to choose a pump for a well on this basis is not a very complicated question. The design head can be determined by the following formula: H calc = (B + K) x 1.15, where B is the height of the house, K is the minimum pressure characteristic (for buildings with a height of less than two floors it is six meters), 1.15 is the coefficient of possible losses. To calculate the actual pressure, the following formula is used: N working = N calculated + Z + L, where Z is the dynamic level of the well, L is the total length of the pipeline. The resulting figure should be rounded to a larger value.
Do I need automation for a submersible pump
For watering the garden, a conventional pump is also suitable, which you need to turn on and off manually. To provide water for a residential building, it is better to purchase a model with automatic equipment. Such equipment is capable of turning itself on and off when necessary. The main elements of the automation system are a relay and a manometer. The first monitors the level of water pressure in the lines. As soon as the owners of the house open the tap, it falls and the relay turns on the pump. Also, the relay can monitor the water level in the well itself. If it falls below a predetermined mark, the pump shuts down. This prevents equipment breakdown. A pressure gauge is necessary so that the owner of the unit can receive information about changes in the water supply system.
Thus, if anything can make the use of the pump as convenient as possible, this is precisely automation. For a well, as well as for a well, it is worth choosing exactly this type of equipment. But it should be borne in mind that units with such an addition are somewhat more expensive than conventional ones. If you wish, you can buy a pump, originally equipped with automation, or purchase the latter separately.
Most popular brands
Next, let's figure out what is the best submersible pump for a well in terms of the manufacturer. Such equipment of various brands is presented on the Russian market. Most of these models are reliable and have a long service life. However, the most popular brands for owners of suburban areas are pumps:
"Gileks Vodomet."
"Aquarius".
Grundfos.
Pedrollo
"Kid".
The trickle.
Reviews on models "Gileks Vodomet"
These are perhaps the most common pumps for wells at the moment. Submersible (which is better - "Vodomet" or some other brand - such a question does not even stand for many summer residents) the unit of this manufacturer is reliable and has a long service life. There are models produced by this company, much cheaper than imported counterparts. Judging by customer reviews, they are almost as good as European units in terms of productivity and service life. In addition, Vodomet pumps are less sensitive to voltage drops than imported models. Consumers consider their maintainability to be a plus for units of this brand. Some owners of suburban areas even repair them with their own hands.
Models "Aquarius": reviews
It is also a very popular well pump. Submersible (which is better, the reviews of many summer residents are unambiguous) the Aquarius aggregate of its owners fails extremely rarely. Models of this brand are produced in Ukraine. The owners of cottages and apartment houses consider their main advantages insensitivity to contaminated water and a long service life. There are models of "Aquarius" almost half the price of foreign counterparts and at the same time they do not break and are notable for good performance.
Consumers consider the main drawback of the equipment of this manufacturer to be quite a lot of weight (the units are not too convenient to install). At the same time, extremely unreliable cables come complete with Aquarius pumps. Many owners of this equipment wish the manufacturer to replace "this flimsy rope" with something more impressive.
Consumer opinion about the models "Kid"
Pumps from this manufacturer have earned good reviews primarily from summer residents engaged in the cultivation of vegetables and fruits. “Baby” models are therefore called so because they have small dimensions and power. The pressure they give is also not too strong. Many owners of suburban areas believe that they are ideally suited for irrigation, but it is better to choose more powerful equipment to equip the water supply system at home. To the undoubted advantages of the models of this brand, without exception, all summer residents attribute a low cost. The price of such products rarely exceeds 2500 p.
Grundfos Pumps
Of all the import brands represented on the Russian market, this is perhaps the most popular. The Grundfos pumps are manufactured by the eponymous corporation, whose plants operate in many countries of the world. The main advantages of these models are insensitivity to contaminated water, very light weight and the presence of a convenient carrying handle. Also, owners of suburban areas praise the pumps of this brand for the fact that they are equipped with a very long power cord (10 meters). A pump with automatic equipment for the Grundfos well, thus, judging by the reviews of the owners of suburban areas, can become simply irreplaceable equipment. Models from this manufacturer are more expensive than domestic, but are still considered to be of higher quality.
Rodnik pumps
Equipment of this brand also differs in not too large dimensions. Like the “Baby” units, these pumps have earned the greatest popularity among the owners of vegetable gardens and gardens. Summer residents speak of them as fairly reliable. Many people buy Rodnik pumps in addition to the main powerful equipment and only use them from time to time. For example, this submersible version of the well equipment, according to the owners of suburban areas, is excellent for pumping a new well, periodically cleaning the tank, etc.
Pedrollo Model Reviews
Pedrollo models are also a very good version of such equipment as pumps for wells (submersible). Which is better, determining the photo may not help, but nevertheless we present just below the image of this particular Italian model, since its popularity has really increased significantly lately. Pumps from this manufacturer are quite expensive. However, the models of this brand are considered among summer residents and better than domestic. Judging by the reviews of the owners of country houses and even specialists involved in the equipment and maintenance of wells and boreholes, this is almost the best brand to date. The advantages of Pedrollo pumps include, among other things, a very long service life and good performance. The only drawback of such models is the owners of country houses consider their high cost.
So, we hope we answered the main question of the article: what is the best submersible pump for a well? For contaminated water, you should buy a vibration model. In a very clean well, it is better to put a centrifugal one. The characteristics of the pump are determined by the needs of the family for water, and the brand is chosen at most in accordance with their own financial capabilities.
