Pressure boosting water pumps arean integral part of almost any hot water system. This equipment is necessary in those moments when the pressure in the water supply network does not allow to fully use household appliances (dishwashers and washing machines, gas water heaters) in those places where centralized water supply is impossible.
Virtually all water pumps that increasepressure are small, so they can be placed directly on the pipeline without any special difficulties. They can easily be operated not only in private households, but also in apartments.
It is also important to note that this equipmentprovides only a slight increase in pressure in the water supply or heating system. But even its minimum increase is considered sufficient to ensure the normal operation of household appliances and to improve the circulation of coolant in heating appliances.
A water pump that increases the pressure of the water works with a liquid at a temperature of 10 to 100 ° C, while the environmental index should not be more than 40 ° C.
Depending on the control method, this equipment can be classified into the following categories:
With manual control, uninterrupted operation of the pumping unit is ensured; shutdown is forced by the operator.
Automatic water boosting pumpspressure, equipped with a flow sensor, which is triggered when the valve is opened and ensures the start of the unit. After closing the valve, the flow stops and the pumping equipment is switched off by means of a sensor.
To date, the construction marketprovides many devices of this type. Therefore, when choosing the most optimal model, it is necessary to be guided by specific tasks and primary attention should be paid to the following technical characteristics:
To reduce the noise level in many household pumping units, the rotating rotor is located directly in the pumped liquid. This design has the name "with a wet rotor."
Pressure-boosting water pumps have many positive qualities, determined by ease of use and efficiency in use:
Жители многоквартирных домов нередко сталкиваются with a situation when additional pressure of water is required, which flows weakly or only drips at all. As a result, there may be interruptions in the functioning of household appliances: showers, water heaters, dishwashers and washing machines. And, of course, it is not necessary to say that with a large number of family members water is vital.
In this case, can only help the water pump, which increases the pressure in the apartment. Based on the degree of efficiency, it is desirable first of all to pay attention to the power consumption.
According to experts, the most reliableequipment are dry rotor pumps. Installations with a wet rotor are demanding on the volume of the pumped liquid. And they also need periodic maintenance.
Choosing a water pump that boosts pressure fordozatrona, it is necessary to give preference to models, manufacturers of which have proven themselves from the best side and have been working in this field for many years. Only in this case, you can get a reliable, high-quality and durable unit that will last for a long time.
Choosing this type of equipment, firstqueue should be familiar with its performance. For example, the recommended pressure in the network should be at least 20 bar. From the acquisition of low-power installations for washing the car, it is desirable to refuse. Despite their affordable cost, they are not able to provide the necessary and high-quality water pressure, which will not allow to wash the car.
There are a lot of manufacturers of these devices, so the most popular models and their characteristics are summarized in the following table:
| Model | Performance | Power | Maximum head |
| UPA 15-90 | 1.8 m2/ h | 118 W | 9 m |
| CL15GRS-15 | 1.5 m2/ h | 120 W | 15 m |
| CL15GRS-10 TAIFU | 1.1 m2/ h | 90 W | 10 m |
As mentioned above, in manual modeequipment is constantly on. In automatic mode, the pump unit is controlled by a flow sensor that starts the installation when creating a small flow of water (about 90-120 l / h) and turns off when dismantling stops.
The type of equipment also depends on the optioncooling his body. For example, TAIFU provides cooling by pumping a fluid or an electric motor impeller. In Grundfos models, cooling takes place only with the help of a pumped liquid. In this case, the water pump, which increases the pressure (the average price is from 6,000 rubles), works almost silently. Manufacturers engaged in the production of installations of this type offer consumers pumps that not only meet European standards, but also operate with the lowest possible noise level or silently.
In any case, it will be very useful to consult with a qualified specialist before purchasing pumping equipment.
