It is often possible to encounter a problem when the pressure of the water supplied centrally is insufficient to satisfy all the needs of the consumer. This applies to both urban and rural water supply systems. In the city, this problem may be due to the fact that the apartment is located on the upper floors of an apartment building. This is especially true of the old housing stock, where the system is not designed for modern volumes of water consumption. In rural areas, pressure decreases, usually during the watering season, when a large amount of liquid is pumped out for agricultural needs. Many electronic devices require a certain minimum water pressure for normal operation. This also applies to automatic washing machines, as well as gas and electric heating systems. There are situations when some users may even be left without water.
To solve this problem, pumps are often used to increase the pressure in the system.
The choice of pump depends on the specific situation. If there is water in your faucet, but it flows too weakly, and the task is to slightly increase the outlet water pressure, then the problem can be solved with a conventional pressure increase pump. Such devices vary in power and pressure increase. Starting from the simplest (increase pressure by 1 atmosphere) and ending with heavy duty (increase to 6 - 7 atmospheres). It must be remembered that performance also affects the size of the pump, as well as the energy consumed. When choosing, it is necessary to check the availability of space in the bathroom to install a particular device. Install them by tapping into the pipe.
Two possible operating modes are manual and automatic. The second option is preferable, as it prevents the undesirable consequences of idling. In automatic mode, the motor only works when the water is on - this, among other things, allows you to save electricity.
It is worth paying attention to the method of cooling the motor. A modern pump that increases the pressure of water is cooled by a flowing fluid. The main advantages are the reliability of this method and the silent operation of the system. In addition, cooling is applied by means of an electric motor impeller. When choosing such a pump, it must be taken into account that it produces some noise during operation.
In addition, when buying, you need to pay attention to whether the pump for each system works separately (hot / cold water) or is it universal. The choice here depends on your needs.
Consider the second version of the problem - if there is no water in the tap, but you know for sure that it is in the system. In such a situation, only a self-priming pump station that can increase the water pressure can help you . Such devices are capable of raising water to a level of up to 8 meters. When choosing a pumping station, pay attention to the presence of a hydraulic accumulator.
So, in order to choose the right pump to increase the water pressure, you need to decide on the following points:
- need a conventional pump or self-priming station;
- what pressure must be obtained at the outlet (depends on the number and power of devices connected to the system);
- how much space are you ready to provide for the placement of the apparatus;
- how much money do you have to buy the device.
When studying the characteristics of a particular pump, pay attention to:
- motor power;
- maximum water consumption ;
- protection class;
- diameter of nozzles;
- maximum water temperature (can I use it for a hot system);
- dimensions and weight.
Before deciding whether to buy a pump or pumping station, you must make sure that the problem with the pressure of the water is caused precisely by an insufficient pressure level, and not by other factors, for example, clogged pipes, etc.
