Pumping station — This is a device that can maintain the desired pressure in the system without human intervention, that is, automatically. The pumping station necessarily includes a pump, as well as additional equipment — a hydraulic accumulator and pressure sensors.
The choice of a pumping station is a very responsible task, the quality of water supply in a country house, in a country house or any other object depends on the correct solution of it.
To choose the equipment that will solve your problems, you need to pay attention to the following points:
-
Type of pumping station
-
Required water supply
-
tank capacity
-
Price
1. Type of pumping station
Pumping stations come with a built-in injector (suction depth 6-10 m, depending on the power of the pumping station) and with an external injector (suction depth from 10 m). Also, pumping stations can be used to increase the pressure in the water supply system.
Pumping stations are demanding on water quality, especially on the presence of solid suspensions in it. Therefore, if poor quality water comes from the source, a filter system should be installed.
Note: the most common pumping stations raise water from a depth of 8 meters, and pump it to different distances along the plane. If the pumping station stands next to the well and its suction hose is lowered to the maximum depth (8 meters), then it can only pump the number of meters on the plane that is stated in the technical data sheet. But the operator can lower the suction hose into the well not to the full depth, but, for example, by 6 meters. In this case, each meter «saved» in the rise of water increases the distance over which the pumping station can transfer water along the plane. If the pumping station is next to the well, then 1 meter vertically will be equal to 10 meters horizontally

2. Necessary water supply
Various models of pumping units offer an average water supply of 1.5-5 cubic meters per hour. The number of water intake points will help determine the required supply. For example, it is planned to bring water home: a bath, a toilet, a kitchen, a washing machine, and additionally to a bathhouse. The average water consumption per point is 0.35 cubic meters per hour. You just need to multiply it by the number of points (in this case, by five) and get the required water supply rate (in this example, 1.75 cubic meters per hour). Thus, you should take a pump, the flow of which is 2 cubic meters per hour (it is better to take the installation with a small margin).
3. Tank capacity
An important point is the selection of the tank capacity, which is also calculated by water supply points. The capacity of one point (faucet) averages 12 liters, respectively, in this example, a tank of 60 liters is required. Quite a few manufacturers, to facilitate the task of buyers, indicate on their pumping units the maximum number of water intake points for which a particular installation is designed.
4. Cost
Finally, the available financial possibilities should be considered. When using a pumping unit exclusively in the summer, you can limit yourself to an inexpensive domestic-made station. If it is planned that the system will work year-round, then it is better to take a more expensive imported installation.
In the case when the purchase of the installation raises additional questions, it is worth consulting with representatives of companies professionally dealing with water supply systems and having extensive experience in this field.
