How to choose a pump for a well?

It is almost impossible to organize the provision of water for a country house without using a pump. Today, there are various models and types of devices for pumping and collecting fluid.

First of all, when choosing a product, it is necessary to pay attention to a centrifugal pump for giving.

There are surface varieties that are installed on the surface of the water and thus draw fluid from wells and boreholes. These devices are very common, they are also called vortex. A similar well pump has a simple principle of operation.

The electric motor located inside the casing rotates the impeller, which creates a rarefied environment, which ensures the absorption of fluid and its movement to the output of the device. Use of an epiploon allows to prevent water leakage between the engine and an impeller.

A centrifugal pump for a well is produced in various capacities, and hence productivity. This characteristic is very important and is determined by the amount of fluid transported depending on the suction depth per unit time, for example, liter per hour, liter per minute. It turns out that the deeper the water mirror is located in the well, the more difficult the pump is to operate, the lower its productivity.

When buying a centrifugal pump for a well, it must be borne in mind that it is able to lift fluid from a depth of at least 8 meters.

Otherwise, a screw-type immersion device will come to the rescue. This option is more expensive, but also reliable. You can buy a cheap model - a submersible pump for vibrating type irrigation, for example, "Trickle". This device allows you to raise water from 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, which is additionally equipped with a hose and a check valve. This design should be lowered down into the well. After she collects the liquid, it is connected to the input of the device. The well pump must also be filled with water to prevent water hammer and damage to the tool. After that, it is included in the network.

Distribution also received automatic water supply stations, which are called hydrophores. The devices are connected to a well or a well and supply and raise water in automatic mode, while the water mirror should not be lower than 8 meters. Such a well pump works in a sealed closed system.

In other words, with a difference in pressure at the inlet and outlet, the device automatically turns on and water is pushed out of the outlet fitting to the place of fluid intake. It turns out that when the tap in the house is closed, the pump is resting and is in standby mode. If the faucet comes off, then water immediately starts flowing out of it, and the device turns on and pumps liquid into a special expansion tank. Thus, it is believed that the house is connected to a water supply system, as in a city.
