Water supply to industrial facilities often requires the connection of high-power pumping equipment. This is due to the need to use large volumes of water at several points. Domestic water supply can do without pressure stabilization due to additional stations, but this is not always the case. To compensate for the lack of pressure allow household pumping stations to increase the pressure of water, which are presented on the market in a wide range.
Features of pressure boosting pumps
The standard organization of domestic water supply systems involves the use of a pump, supplemented by a pressure sensor. The disadvantage of this solution is that the pressure increase indicator should work every time a pressure deficit is fixed. If the initial circulation of water meets the demands of consumption in terms of ensuring sufficient pressure and “dips” occur infrequently, then this option justifies itself. But if optimal pressure support is needed in the constant operation of plumbing equipment, then the best solution would be the station to increase the water pressure in the house or apartment. Such units are distinguished by the presence of a hydraulic accumulator and a pressure switch - these devices are designed to compensate for pressure indicators based on the characteristics of a particular water supply.
The main feature of such complexes is precisely the accumulator, which accumulates not only water, but also potential energy. During operation, the fluid first enters the accumulator, and then to the direct consumer. After the resource in the tank is exhausted, the station for increasing the water pressure gives a signal to the pump, which repeats the accumulation cycle. As a result, the same water supply function is provided, but adjusted for pressure stabilization at the optimum pressure level.
Main characteristics of the stations
The main indicator of the station's compliance with the specific needs of the water supply system is productivity. On average, household plumbing devices require from 0.09 to 0.13 l / s. This applies to the volumes of water with which the equipment will work, but the pressure itself is no less important. Typically, in standard household circulation systems, the pressure is half the atmosphere. In the presence of one crane, this indicator may be sufficient, and it may well be limited to installing a typical pump with the mentioned pressure sensor. In turn, the station for increasing water pressure for a private house ensures the reliable operation of several points of consumption. So, if several cranes are used, then an aggregate capable of operating at a pressure level of 1.5 Atm as a minimum is required. That is, additional support will raise the pressure by 1 Atm. As an alternative value of a suitable pressure level, the height of the water column can also be considered. The same 1.5 Atm will correspond to 10 m of ascent. By the way, standard systems for small private houses work on lifting up to 8 m.
Varieties of aggregates
There are two criteria for separating aggregates of this type. The first determines the way the system is controlled - manual or automatic. In the case of manual control, continuous operation of the installation is ensured, so the user must independently monitor the condition of the equipment. For example, it is necessary to ensure that the equipment is turned off on time and does not overheat. According to this principle, a mini-station for increasing water pressure operates, designed to service undemanding power networks. Automation is often used in production complexes, which should have an effective system of protection against "dry" work. The second principle of separation of equipment involves classification by type of cooling system. From the point of view of operating comfort, it is more advantageous to use rotor units cooled by blades. These are silent stations, which also feature high performance. An alternative to such systems is a “wet” pump, the cooling of which occurs due to the passing water flows.
Grundfos UPA 15-90 reviews
The system is a complex, which is based on a glandless pump, provided with a "wet" rotary mechanism. The products of a German company are often praised for a detailed and accurate design calculation in terms of reliability. The UPA 15-90 station was no exception. In its device, a stainless steel protective sleeve is provided that separates the electric motor and the stator. Owners note the convenience of controlling mechanisms. Already in the basic equipment, the station for increasing the water pressure of the UPA 15-90 modification is provided with an ergonomic terminal box, due to which the owner can adjust the operating modes. Users also include the small size of the pumping station as an advantage - this allows it to be used in various types of domestic water supply systems. But not only the structural possibilities of installation, the dimensions of this model are beneficial. Water supply, depending on the season or changing customer requirements, may involve operation with a minimum level of pressure. The Grundfos unit is also suitable in this case, since the pressure at the suction pipe can only be 0.2 bar.
Metabo HWWI 4500/25 reviews
Another representative of the advanced segment of pumping equipment. If the above model is more suitable for stabilizing the pressure in apartments and small houses, then the HWWI 4500/25 proves itself worthy in servicing suburban cottages. According to users, the complex's capacity of 1300 watts is enough to service entire households. That is, the potential covers the communal needs of water supply not only indoors, but also outside them. The case, made of stainless steel, coupled with a durable metal tank, allows you to install the structure directly on the street. As for the shortcomings, many note the cost at which this station for increasing water pressure is implemented. The average price is 14-15 thousand rubles, which is a lot for a representative of household pumping equipment.
Wilo PB-400EA pump feedback
The developers of this station balanced approach to design design. This is a small medium power unit equipped with a modern control system. At the same time, users point out the fact that the model is focused on working with cold water. The unit can be operated in standalone mode - the automation, supplemented by a water flow sensor, independently monitors the performance indicators. The list of advantages that a pump station for increasing water pressure from Wilo has is also included in the low noise level and protective systems that exclude overheating and dry running.
Pedrollo 4CPm 100-C-EP 1 Reviews
The 3-4 range represents multistage electric pumps provided with a horizontal shaft and a body made of cast iron. The device of such models is based on the principle of a variable number of impellers. That is, during operation, the pump wheels of the unit communicate the optimum pressure to the fluid, which equalizes the fluid circulation throughout the water supply system. According to users, the station for increasing water pressure of this type provides high-quality performance of a direct function, as well as being economical in maintenance and quiet operation.
How to choose the best option?
When buying a booster domestic pump, three main factors should be considered. First of all, it is the compliance of the operating characteristics with the requirements of the target water supply system. The best option would be a complex with the ability to automatically control the pressure, which will independently adapt to the features of the network. The second factor is related to reliability. Several reliability indicators are noted, which are used to evaluate the station for increasing water pressure for private houses and apartments. Among them, one can note the material of manufacture of the case, the presence of protective systems, as well as a thoughtful design that initially minimizes the wear of the element base. The third aspect of the choice of such stations is due to economic considerations. Systems focused on long-term operation should include balanced energy consumption.
Conclusion
Elevation stations should not be considered as a mandatory addition to any water supply pipeline. Moreover, not every system that requires maintaining high pressure needs stabilization due to auxiliary mechanisms. Conversely, simple networks with a small number of sampling points, even with minimal demands, may need a station to increase the water pressure. Household systems of this type equalize pressure indicators where circulation is initially unable to provide sufficient pressure. Again, in some cases, you can get by with typical pumping equipment with monitoring sensors. For example, standard circulation pumps can quite cope with the task of normalizing the pressure. The only problem is that their design, unlike booster pumps, is not specifically designed to compensate for pressure at a low water flow rate - as a result, there is a risk of premature failure of the working mechanisms.
