How to choose a pump for a well?

It is practically impossible to organize water supply for a country house without using a pump. Today, there are various models and types of devices for pumping and sampling liquids.

First of all, when selecting a product, it is necessary to pay attention to a centrifugal pump for cottages. There are surface varieties that are installed on the surface of the water and thus produce fluid intake from wells and wells. These devices are very common, they are also called vortex. A similar pump for a well has a simple operating principle.

The motor located inside the casing produces the rotation of the impeller, which creates a rarefied environment, which ensures the absorption of the liquid and its movement to the output of the device. To prevent the flow of water between the engine and the impeller allows the use of an oil seal.

The centrifugal pump for the well is produced in various capacities, and hence in productivity. This characteristic is very important and is determined by the amount of fluid moved in dependence on the suction depth per unit time, for example, liter per hour, liter per minute. It turns out that the deeper the mirror of water in the well, the more difficult it is for the pump to work, the less its productivity.

Buying a centrifugal pump for a well, it must be taken into account that it is capable of lifting liquid from a depth of at least 8 meters.

Otherwise, a screw-type submersible device will come to the rescue. This option is more expensive, but also reliable. You can buy a cheap model - a submersible pump for watering a vibrating type, for example, "Brook". This device allows you to lift water from a 50 meter depth.

However, if a serious pressure of water is required for irrigation or water supply, it is better to use a surface centrifugal device that is additionally equipped with a hose and a check valve. This construction should be lowered into the well with the valve down. After she collects the liquid, it is connected to the input of the device. The pump for the well must also be filled with water to prevent water hammer and breakage of the device. After that, it is included in the network.

Distribution also received automatic water supply stations, which are called hydrophores. Devices are connected to a well or a well and the water is supplied and lifted automatically, while the water mirror should not be below 8 meters. Such a pump for the well operates in a sealed closed system.

In other words, with a difference in pressure at the inlet and outlet, the device switches on automatically and the water is pushed out of the outlet nozzle to the point of fluid intake. It turns out that when the tap in the house is closed, the pump rests and is in the standby mode. If the tap comes off, water immediately flows out of it, and the device turns on and pumps the liquid into a special expansion tank. Thus, there is an opinion that the house is connected to the water supply system, as in the city.
