Water pumps that increase pressure are an integral part of almost any hot water system. This equipment is necessary in those moments when pressure in the water supply network does not allow the full use of household appliances (dishwashers and washing machines, gas water heaters) in places where centralized water supply is not possible.
Features
Almost all pressurizing water pumps are small-sized, so they can be placed directly on the pipeline without much difficulty. They can be easily used not only in private households, but also in apartments.
It is also important to note that this equipment provides only a slight increase in the pressure indicator in the water supply or heating system. But even its minimum increase is considered sufficient to ensure the normal operation of household appliances and improve the circulation of the coolant in heating appliances.
A water pump that increases water pressure works with liquid temperatures from 10 to 100°C, while the ambient temperature should not exceed 40°C.
Varieties
This equipment can be classified according to the control method into the following categories:
- Manual.
- Automatic.
With manual control, uninterrupted operation of the pump unit is ensured, shutdown is forced at the initiative of the operator.
Automatic water pumps that increase pressure are equipped with a flow sensor that is activated when the tap is opened and ensures that the unit starts. After the valve is closed, the flow stops, and the pumping equipment is turned 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 primary attention to the following technical characteristics:
- Noise level.
- Power.
- Maximum possible pressure.
- Performance.
To reduce the noise level in many domestic pumping installations, the rotating rotor is located directly in the pumped liquid. This design is called "wet rotor".
Benefits
Water pumps that increase pressure have manypositive qualities determined by ease of use and efficiency in use:
- Operating over a wide temperature range with a variety of fluids.
- Low power consumption.
- A flow sensor ensures automated operation.
- Ease of dismantling and installation work.
- Possibility of mounting directly on the pipeline.
- High resistance to corrosion processes.
- Noise level acceptable during operation.
- Small overall dimensions.
- The ability to increase and maintain stable pressure in water supply and heating systems.
Using pumps in apartments
Residents of apartment buildings are often faced with a situation where additional water pressure 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, 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 help, which increases the pressure in the apartment. Based on the degree of efficiency, it is desirable to pay attention first of all to the power consumption.
According to experts, dry rotor pumps are the most reliable equipment. Glandless installations are demanding on the volume of pumped liquid. And also theyneed periodic service.
Wash equipment
When choosing a water pump that increases pressure for a dosatron, it is necessary to give preference to models whose manufacturers have proven themselves from the best side and have been working in this field for many years. Only in this case you will be able to purchase a reliable, high-quality and durable unit that will last for quite a long time.
When choosing equipment of this type, first of all, you need 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 purchase 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 quite a few manufacturers of these devices, so the most popular models and their characteristics are summarized in the following table:
| Model | Performance | Power | Max head |
| UPA 15-90 | 1, 8m2/h | 118 Tues | 9 m |
| CL15GRS-15 | 1.5m2/h | 120 W | 15 m |
| CL15GRS-10 TAIFU | 1, 1m2/h | 90 W | 10 m |
As mentioned above, in manual mode, the equipment is constantly on. ATIn automatic mode, the pump unit is controlled by a flow sensor, which starts the unit when a small water flow is created (about 90-120 l / h) and turns it off when the drawing stops.
The type of equipment also depends on the option of cooling its case. For example, TAIFU provides cooling by pumping a liquid or an electric motor impeller. In Grundfos models, cooling occurs only with the pumped liquid. In this case, the water pump that increases the pressure (the average price is from 6,000 rubles) works almost silently. Manufacturers of this type of installation 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.
