Submersible pumps for wells. Selection of a pump for a well: characteristics, prices
The well is a source of fresh, cold and clear water. But nowadays it hardly makes sense to carry water in buckets. The lesson is not the hardest thing, but when it comes to large volumes, it takes quite a lot of time. That is why it is advisable to use submersible pumps for wells. Such devices allow to avoid manual raising of water. In addition, the performance of the equipment is much higher.
The submersible pump is called so because it works under water. For example, there are surface pumps installed on a special platform or just on top of a well or well. But the essence of submersible pumps is that they can work all year round, as opposed to surface pumps. But about all this a little later.
I would like to note that you need to approach the choice of such equipment not in the store, but also at the dacha. In particular, at the first stage it is necessary to determine the following parameters:
- The depth of the well.How to check it out is hardly necessary to talk. If a well or well was made by experts, then you can just look at the passport.
- The static depth is the depth from the ground surface to the mirror. Measurement is preferably carried out when the well is full.
There are other parameters, such as the debit of the well, the diameter of the rings, etc. Well, now let's go further and dive further into this topic.
About submersible pumps
It is this type of pump that is used when the depth of the well is significant. A pump of this type is partially or completely immersed in water. As you understand, the case in this case will constantly be exposed to corrosion. Therefore, it is made of special materials or polymers.
In this case, it is extremely important to observe the power / performance ratio, because this is the only way to buy a good pump for a well. The submersible type of equipment is also good because it is possible to choose the depth of the dive - usually it is from 1 to 7 meters. But when choosing, be sure to pay attention to the presence of automation and protection against dry suction. By the way, if the well or well is too deep, then a well pump will do.It allows you to lift water from a greater depth. However, we will talk about how to choose submersible pumps for wells. Let's see what their key features are.
Submersible pumps for wells: the price and something else
The first thing you need to deal with the cost of equipment, and only then talk about the technical characteristics. Much depends on performance, power, immersion depth and device manufacturer. For example, the domestic company "Aquarius" produces relatively inexpensive equipment. Pumps from 1.8 to 3.8 m are commercially available.3/ hour cost from 3 to 7 thousand rubles. In this case, all models give a different pressure.
As for the European models, they are significantly more expensive. Usually we are talking about the cost of 10 000 rubles and above. So, the Sprut well pump will cost 12,000, but the cheapest option from Verk is only 2,500 rubles. In any case, you must first calculate your budget, and only then go buy. Well, in the next stage, submersible pumps for wells are selected on the basis of technical characteristics. Let's talk about it.
Technical characteristics of submersible pumps
As you understand, currently there is equipment for every taste. But as an example, let's consider a submersible pump for the Aquarius well. This manufacturer has different models, so let's take a look at them as a whole. The company offers screw submersible pumps (SPL) with a capacity from 0.3 to 5.2 liters per second. In this case, the pressure, depending on the model, can be from 30 to 90 meters.
In the range there are household submersible pumps. This is usually just the kind of equipment that is great for a shallow well. Here the performance is from 1.2 to 2.6 liters with a pressure of 12 to 20 meters. In any case, the range of prices is not so large, so it is better to buy a pump with a power reserve. But here it is necessary to understand that if his performance is too high, he will choose the water dry, which is not good.
Submersible well pump: consumer reviews
It is far from always that those who have unsuccessfully selected them speak of submersible pumps, and this is a fact. Although much depends on the manufacturer. For example, Chinese pumps are not famous for quality, because they often break down, but at the same time they are quickly and cheaply repaired.But European equipment from manufacturers such as PEDROLLO or CALPEDA, has excellent quality and good performance, on which satisfied consumers have repeatedly emphasized.
As for domestic companies, it is their pumps that are most often purchased by Russians. This is due to the fact that they have a relatively affordable price and it is quite easy to repair them in the event of a breakdown, since there are a lot of spare parts on the market. But the most important thing is enough quality equipment. Oddly enough, the domestic manufacturer offers a good price-quality ratio. Therefore, if there is no money for expensive European-made equipment, and China is not satisfied in quality, buy domestic submersible pumps.
The choice of such equipment must be approached seriously. Take into account the needs of your family, the possible performance of the pump and how much a well can give you water. Once you find a middle ground, then you need to make a purchase. In principle, submersible pumps for wells can be used for quite some time.But remember that the fluctuations of electricity, hose filled with debris - all this can cause imminent breakage. Therefore, it is recommended to purchase pumps that have as much automation as possible. Protection against dry suction, check valve, overheating sensor, etc. - all this will help in time to turn off the equipment. By the way, a submersible pump is just that technique that should work for a long time without shutting down. If you constantly turn it on and off, nothing good will happen.
