Pressure boosting water pumps are an integral part of almost any hot water system . This equipment is necessary at those times when the pressure in the water supply network does not allow the full use of household appliances (dishwashers and washing machines, gas water heaters) in those places where centralized water supply is not possible.
Features
Almost all water pumps that increase pressure are small-sized, so they can be located directly on the pipeline without any difficulties. They can be easily operated not only in private households, but also in apartments.
It is also important to note that this equipment provides only a slight increase in pressure in the water supply or heating system. But even its minimal increase is considered sufficient to ensure the normal operation of household appliances and improve the circulation of the coolant in heating devices.
A water pump that increases the pressure of water works with a liquid with a temperature of 10 to 100 ° C, while the environmental indicator should not be more than 40 ° C.
Varieties
This equipment can be classified according to the control method into the following categories:
With manual control, uninterrupted operation of the pumping unit is ensured, shutdown is performed at the initiative of the operator forcibly.
Automatic water pumps that increase the pressure are equipped with a flow sensor, which is triggered when the tap is opened and ensures the unit starts. After closing the valve, flow stops and the pumping equipment is switched off by means of a sensor.
main parameters
Today, the construction market provides many devices of this type. Therefore, when choosing the most optimal model, it is necessary to be guided by specific tasks and pay paramount attention to the following technical characteristics:
- Noise level.
- Power.
- The maximum possible pressure.
- Performance.
To reduce the noise level in many domestic pump installations, the rotor rotor is located directly in the pumped liquid. This design is called "wet rotor."
Benefits
Water pumps that increase pressure have many positive qualities determined by ease of use and efficiency when using:
- Operation over a wide temperature range with various liquids.
- Low consumption of electric energy.
- The presence of a flow sensor provides automated operation.
- Simplicity of dismantling and installation works.
- Possibility of mounting directly on the pipeline.
- High resistance to corrosion processes.
- An acceptable noise level during operation.
- Small overall dimensions.
- The ability to increase and maintain stable pressure in water supply and heating systems.
Use of pumps in apartments
Residents of apartment buildings often face a situation where an additional pressure of water is required, which flows weakly or even only drips. As a result, interruptions may occur with the functioning of household appliances: showers, water heaters, dishwashers and washing machines. And, of course, there is no need to say that with a large number of family members, water is vital.
In this case, only a water pump can increase the pressure in the apartment. Based on the degree of profitability, it is advisable first of all to pay attention to the power consumption.
According to experts, the most reliable equipment is dry rotor pumps. Wet rotor units are demanding on the pumped liquid volume. And also they need periodic maintenance.
Washing equipment
When choosing a water pump that increases the pressure for the dosatron, it is necessary to give preference to models whose manufacturers have proven their best side and have been working in this area for many years. Only in this case you can purchase a reliable, high-quality and durable unit that will last quite a long time.
When choosing equipment of this type, first of all, it is necessary to familiarize yourself with its performance characteristics. For example, the recommended pressure in the network should be at least 20 bar. It is advisable to refuse the acquisition of low-power car wash installations. Despite their affordable cost, they are not able to provide the necessary and high-quality water pressure, which will not allow washing the car.
Popular models
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 m 2 / h | 118 watts | 9 m |
| CL15GRS-15 | 1.5 m 2 / h | 120 watts | 15 m |
| CL15GRS-10 TAIFU | 1.1 m 2 / h | 90 watts | 10 m |
As mentioned above, in manual mode, the equipment is constantly on. In automatic mode, the pump unit is controlled by a flow sensor, which starts the installation when creating a small flow of water (about 90-120 l / h) and turns off when the analysis stops.
The cooling option of its case also depends on the type of equipment. For example, TAIFU provides cooling by pumping liquid or an electric motor impeller. On Grundfos models, cooling is only possible with the 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 plants of this type offer consumers pumps that not only meet European standards, but also operate with the lowest possible noise level or noiselessly.
In any case, it will be very useful to consult with a qualified specialist before purchasing pumping equipment.
