Depth pumps for individual water supply

Water is the basis of life. Therefore, everyone wants to have water supply, sewerage, heating on his plot, in the house or on his own production. And it's good if the work of all these communications is constant and uninterrupted. Especially it concerns water supply. Fortunately, today there are practically no problems with drilling a well in your dacha or near a country house and pump water from it using a pump.

It is economically more feasible to organize water supply from wells, than to arrange a water supply in another way. And surface pumps can only be used with a sufficiently high water level. Therefore, deep pumps, despite their relatively high cost, are very popular. All of them are multistage, which helps them to raise water from a fairly large depth (sometimes up to 300 m). Thanks to this, they got their name. In addition, deep well pumps have a high head. But they can not be too deep into the water. The maximum permissible immersion depth for them is 20 m. If the pump is lowered deeper, the insulation can not withstand. Also, such pumps are easy to install, they are compact and quiet. Among the shortcomings can be called a high degree of complexity of maintenance.

Deep pumps are available in a wide range and are available under various brands, for example, Grundfos, Pedrollo, Needle, Sprut, ZDC, Pumps + etc. All of them can maintain their efficiency in difficult conditions and provide the house or site with water even from the deepest wells. There are vortex, centrifugal and screw pumps: vortex pumps are designed only for clean water, for a liquid with a high content of impurities it is worth using more expensive centrifugal or screw. Downhole pumps can be well type or directly deep. By appointment, deep pumps are for wells, wells, as well as drainage and fecal.

Well pumps are uniquely arranged. The water intake comes from the middle, the pumping part is at the top, and the engine, which operates constantly and under very severe conditions, is located at the bottom. Due to this, it is continuously and effectively cooled by the flow of water flowing between the well wall and the pump. And the smaller this distance, the greater the speed of water movement and, accordingly, the better cooling. Typically, the documentation indicates which maximum diameter a well can be (wells with a diameter of up to 3 inches are not available). If the actual diameter of the well exceeds the allowable value, the pump is fixed in the casing and is already lowered with it. The same principle applies to the use of deep-well pumps in wells and open reservoirs. Most of them can be installed in a horizontal position, but you need to make sure that the documentation indicates this possibility.

Recently, a widespread problem has been the presence in the water of abrasive inclusions, because of which deep pumps can quickly fail. Even if the well is equipped with a high-quality filter, a part of the sand still gets into the water, and because of this, the impellers wear out more quickly. Therefore, modern models of pumps have a wear-resistant coating on the wheels and a floating suspension.
