I do not know how you, dear readers, but for me a trip to the country - a solid offering. And almost all have to sacrifice, what is so accustomed to his cozy apartment in Moscow. Here's the other day just plugged in the country of the microwave oven, as neighbors shouted obscenities good, they say, light them off ... Well, it's okay, it's all small stuff, you can finally, in the country and without miracles of electronics to do ... But the lack of water and sanitation has seriously poisoned existence. Water for watering the garden, and just for domestic use have to pull out of the public well. Benefit is still refreshing source of only five meters away from my site. In the end, the agenda stood the burning question: you need a water pump. The more that a standard 20-foot hose is quite enough to reach the well. "Such questions, my dear Ambassador, with kondachka not be solved" - I recalled the words of Georges Miloslavskogo, a great friend to us the notorious Ivan Vasilyevich. Simply put, you need to know which pump is better to buy. The pumps were found to be different. I would even say - totally different, for a variety of needs. We are with you, of course, interested in domestic pumps. They come in three varieties. Water pumps are suitable for pumping clean water, without any admixture of sand, grass, algae and frogs. By the way, just what I need: and garden watering, and the shower to rinse, wash dishes and drainage pumps are designed for dirty water, mixed with sand, silt, algae, wood chips and other small debris. In principle, also useful in the economy thing. If the nearest well with clean water an hour and a half away, so the pump can be used for watering the garden and the water can be taken from the nearest ditch or pond. But the main purpose of the drain pump - pumping contaminated water from basements, cellars and other places where she likes to collect spring. Fecal pumps designed for pumping waste of the human body, for sanitation, in one word ... This pump is easy to cope with highly contaminated water from the basement or drainage ditch. No, I just feel obligated to say this: drain pump may well replace the water and fecal generally can work for three - for himself, for water and a drainage pump. But! The more complicated the design of the pump, the higher the price. Therefore, from the whole family everyday suburban water pumps are the cheapest, drainage - one and a half times more expensive, and fecal most expensive. So before buying a pump to determine for what purpose you need it, not to spend the extra money. Submersible against surface All of the submersible pumps are divided into and superficial. Submersible pumps, as the name implies, fall directly into the water. A surface mounted on the shore and with a reservoir connected to an ordinary hose. Surface Pump PLUS: easy to assemble and dismantle, requiring only cleaning and lubrication of parts ejector. DISADVANTAGES: Can be used only where ground water come close to the surface. For deep wells and water wells unusable. And yet. Surface pumps can pump water to a height of 30-50 meters (some models - and above), but suck in water from 15 to 20 meters deep they can not - is simply impossible. Meanwhile, in the suburbs is not uncommon, when the water is located precisely at such a depth below ground. What should I do? If the water does not want sucked, because the pump from her too far, let's reduce this distance. Until when will diminish? A zero! That is, throw the pump into the water. For example, I have to testify artesian well - the depth of 18 meters. So, to get water, the surface pump is not suitable. This task is quite handle a submersible pump with a capacity of 200 watts. Two hundred watts - this is quite a bit, believe me. Submersible Pump PLUS: can be used in wells and boreholes to a depth of 40-50 meters. Requires no special installation, does not occupy much space in the water runs almost noiselessly. DISADVANTAGES: inconvenient to maintain, because you must remove it from the well or wells. Submersible pump hard parsed due sealed enclosure. But to do so will, if need lubrication and cleaning the moving parts. The main area of ??submersible pumps - in deep, narrow holes. Specifically for this purpose pumps are made of cylindrical shape and small - from 8 inches - diameter. But, again, a submersible pump is indispensable for deep wells. If the water meter to two, it makes sense to use a surface pump. It can be installed under a canopy, in a barn or anywhere else, tightly-screwed tightly bolted to the floor, but on the night locked room with a key. Otherwise, the pump simply be stolen. In this sense, a submersible pump will bring you some inconvenience. Of course, and well, and well, where the pump is submerged, you can close the lid, and again locked. But there remains another problem. That the pump could be at any time to get it, he is tied to an immovable object on the ground a nylon rope or thick fishing line. And she and the other does not rot from long contact with water, but can pereteretsya, break or simply slip out of hands. In this case the pump is completely immersed, and you will not get it ever. Pull it out of the hose or power cord is almost impossible: their position is not designed for this turn of events. And trying to pull for them will cause the pump just gets stuck in the borehole. In general, the submerged pump to gently but firmly. Specifications Another figure which characterizes domestic pumps - the amount of water that is pumped per unit time. If translated into normal language, the performance of the pump shows you how much it would take to fill, say, a 200-liter drums. For example, with capacity of 5 cubic meters per hour the pump will fill a barrel for 2.5 minutes. The higher the productivity, the process will go faster than the lower - the slower. Suppose it is well known domestic submersible pump is "The Kid" (incidentally, very good) has a capacity of 1.5 cubic meters per hour. Barrel will fill up to 8 minutes, not bad, considering that the process of filling the barrel by hand (with buckets) takes much more time and effort. In addition, the performance of the pump is directly related to height, which accounts for raising water. The same "kid" if you have to pump water from the 18-meter well, reducing productivity up to 0.85 cubic meters per hour - almost twice! On the other hand, do not worry, the barrel is 15 minutes - well tolerated. Model on the markets and shops of domestic producers are, unfortunately, is not so wide and beautiful as imports, but on some models, I would like to talk about. Above all, this submersible pump "Babe" (the price of 750-950 USD., Depending on the length of electrical cable) with protection against overheating (model without protection I never met) and its more powerful and "paunchy" brother, "Irrigation" (1200 rub .). From surface pumps are the most common model Kama 10 and Agidel "(and its counterpart" Palesse "from fellow Belarusians). Kama 10 "(1200 rub.) - Not a bad unit, but Agidel" in 1991 were going to phase out both technically and morally outdated model ... but still produce and sell to 1200-1250 rubles. (Palesse "costs about the same). Model BN-2-40 from Moscow pumping plant one in a "sketched" from the Italians, but gives them the appearance. Submersible Pump "Grundfos" dirty water But imported goods is mainly represented by the German trademark Grundfos («Grundfos"), a joint Italian-Japanese creature named Ebara («Ebara") and half-dozen Italian brands, like as two peas in a pod (company "Astra", "Nochchi" and others). They look about the same and the outside and the internal mechanics are no different and the principle of action. All of them are quite reliable and had a good idea to establish itself in the work. Still, German quality prevails. And the vendors, and neighbors on a summer residence, and even interrogated me with an addiction specialist Mosvodokanal who wished somehow to remain anonymous, in one voice urged to buy a pump made in Germany ... pump or "The Kid" with protection against overheating. Personally, I like a patriot is nice. To summarize. For clarity, propose to consider some of the most common problems of "mining water" in the country. And, accordingly, their decision. The problem of how to get water from the well or wells for domestic use and watering the garden? Need a solution of a water pump for shallow (up to 5 meters), wells and boreholes. For deep wells (more than 5 meters) needed a submersible pump. How to take the problem of dirty water from wells, ditches, basements, cellars, swimming pools? Need a solution drainage submersible or semi-submersible pump (the water falls only its lower part) with manual or automatic switching. When the automatic activation of the pump itself will be included every time the water level will rise up to the maximum mark. (The so-called float switch.) Problem Like divert sewage and dirty water? Need a solution fecal pump with automatic or manual switching. Automatic switch will provide the starting of pump when water reaches a certain level, or every time you pour water into the toilet or sink. Other variants of automatic switching, to be agreed with the seller and installer of pumping equipment. And the last. Make their own sewer strongly recommend - is complex, requires specialized knowledge and skills. Otherwise, sink ... Well, let's say in the issues. Expert opinion Gennadiy, the emergency services Mosvodokanal: I have 20 plus years I was dealing with pumps of different brands and sizes. I know from experience that the surface pumps are used not rational. According to the documents they need to pump water from depths up to 8 m, but in practice this figure is reduced to 6-7 m. At the depth of the submersible pumps, "capture" of water at least five times greater. Therefore, submersible pumps are more universal. Take, for example, the pump is "The Kid", which is widely used by gardeners. A good pump. Designed for wells with a diameter of 6 inches (just over 15 cm). "The Kid" requires virtually no maintenance, is not heated, since it serves as a natural cooling of the pumped water. A surface pump on a hot summer day can be heated so that the thermal protection device will automatically switch off the pump once every 30 seconds. And yet. I want to give good advice. In fact, what is well? This hole in the ground where pipe is inserted to the wall well did not crumble and not clogged hole. So, skvazhenny pump diameter, for example, 80 mm tube diameter of 85 mm and can not get through. Why? Because our pipes - the most bent pipe in the world. Therefore, the diameter of the pump must be chosen with a margin that was less than the diameter of the pipe at least 10-15 millimeters. With regard to production of the Moscow pumping plant, the model of the BN-2-40 (surface pump) is copied from the Italian pump. True, we Pump inferior Italian appearance and packaging. And so - no worse than imported. Yuri Kurt, engineer, head of the firm "Grundfos" in Moscow: What are the advantages of our products? First of all, our pumps - it's build quality and reliability. Of course, the seller of another company will tell you about my product is the same. But the "Grundfos" is quite specific accomplishments, which to date no one has. For example, skvazhennye (submersible) SQE pumps can provide a constant pressure of water at varying flow rates. This means that for these models, it does not matter whether the pump feeds a faucet or while supplies water intake of ten points, including the irrigation system - the water pressure in all cases is the same. Other well-known brands of household pumps is to ensure that they can not - their water pressure is determined by the amount of open water taps. The more points of withdrawal (shower, garden irrigation system, etc.), the thinner the trickle of water. Second moment. It is well known: the smaller the diameter of the submersible pump, the easier it put him into a narrow deep wells. So, the diameter pumps SQ mark "Grundfos" - from 3 inches (about 76 mm), and other well-known pump manufacturers produce models with a diameter at least 4 inches (slightly more than 100 mm). Hence the conclusion: this is not a massive pump in each well will go.
