Water pressurization station in the house: overview, views, features, reviews

Water supply of 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 manage without stabilizing the pressure due to additional stations, but this is not always the case. Compensate for the lack of pressure allow household pumping stations to increase water pressure, which are on the market in a wide range.

Features of pressure boosting pumps

The standard scheme of 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 be activated every time the pressure deficit is fixed. If initially the circulation of water corresponds to the demands of consumption from the point of view of ensuring sufficient pressure and "failures" occur infrequently, this option justifies itself. But if the support of optimum pressure is needed in a constant mode of operation of plumbing equipment, then the best solution will be the station for increasing water pressure in the house or apartment. Such units are characterized by the presence of a hydraulic accumulator and a pressure switch - these devices are designed to compensate for head pressure with the calculation for the characteristics of a particular water pipe.

The main feature of such complexes is the hydroaccumulator, 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 exhaustion of the resource in the tank, the station for raising the water pressure signals the pump, which repeats the accumulation cycle. As a result, the same water supply function is provided, but with correction for stabilizing the head at the optimum pressure level.

Main characteristics of stations

The main indicator of the station's compliance with specific requests of the water supply system is productivity. On the average, household plumbing devices require from 0.09 to 0.13 l / s. This concerns the volume of water with which the equipment will operate, but the pressure itself, which is determined by pressure, is equally important. Typically, in standard domestic circulation systems, the pressure is half-atmosphere. In the presence of one tap, this indicator can be sufficient, and it is quite possible to confine ourselves to installing a typical pump with the said pressure sensor. In turn, the station for increasing the water pressure for a private house ensures the confident operation of several points of consumption. So, if several cranes are used, an aggregate will be required, capable of operating at a pressure level of 1.5 atm as a minimum. That is, additional support will raise the pressure by 1 Atm. As an alternative value for 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 the rise. By the way, the standard systems for small private houses are operating at an elevation of up to 8 m.

Types of aggregates

There are two criteria for separating aggregates of this type. The first determines the way the system is operated - manual or automatic. In the case of manual monitoring, continuous operation of the plant is ensured, therefore the user must independently monitor the state of the equipment. For example, you need to ensure that the equipment is switched off in time and does not overheat. On this principle, there is a mini-station for increasing water pressure, designed to service networks that are not demanding for power. Automation is more often used in productive complexes, which must have an effective system of protection from "dry" work. The second principle of equipment separation assumes a classification by type of cooling system. From the standpoint 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, cooling in which occurs due to the flow of water.

Reviews of model UPA 15-90 from Grundfos

The system is a complex based on a helical pump provided with a "wet" rotary mechanism. The products of the German company are often praised for detailed and verified design calculations in terms of reliability. Station UPA 15-90 was no exception. In its device, there is a protective sleeve made of stainless steel separating the electric motor and the stator. Mark owners and the convenience of management mechanisms. Already in the basic equipment, the UPA 15-90 water pressure increase station is provided with an ergonomic terminal box, due to which the owner can adjust the operating modes. To the pluses users also include small dimensions of the pumping station - this allows it to be used in domestic water pipes of various types. But not only the design possibilities of installation are advantageous in the dimensions of this model. Water supply, depending on the season or changing requirements of the consumer, can assume work with a minimum level of pressure. The Grundfos unit is suitable also in this case, since the pressure on the suction nozzle can be only 0.2 bar.

Reviews of the model HWWI 4500/25 from Metabo

Another representative of the advanced segment of pumping equipment. If the above-described model is more suitable for stabilizing the pressure in apartments and small houses, the HWWI 4500/25 adequately manifests itself in servicing country cottages. As the users note, the capacity of the complex in 1300 watts is enough for the maintenance of whole households. That is, the potential covers the communal needs of water supply not only inside the premises, but also outside them. The case, made of stainless steel, coupled with a metal solid tank, allows you to install the structure directly on the street. As for the shortcomings, many note the cost by which the given station of increasing water pressure. The average price is 14-15 thousand rubles, which is quite a lot for a representative of household pumping equipment.

Responses to the Wilo PB-400EA pump

The developers of this station have approached the design of the structure in a balanced way. It is a small unit of medium power, equipped with a modern control system. At the same time, users point to the fact that the model is aimed at working with cold water. The unit can be operated in an autonomous mode - the automation, supplemented with a water flow sensor, independently monitors performance. The list of advantages that the pumping station has for increasing the water pressure from the manufacturer Wilo, also low noise and protective systems, eliminating overheating and dry running.

Comments about 4CPm 100-C-EP 1 from Pedrollo

Ruler 3-4РР represents multistage electropumps provided with a horizontal shaft and the case executed from pig-iron. The design of such models is based on the principle of variable number of impellers. That is, in the process of operation, the pump wheels of the unit inform the fluid of the optimum pressure, which equalizes the circulation of the liquid throughout the entire water supply system. According to users, the water pressure boosting station of this type provides high-quality performance of direct function, and also differs economy in service and noiselessness of operation.

How to choose the best option?

When buying an upswing pump, three main factors should be considered. First of all, this is the correspondence of performance characteristics to the requirements of the target water supply system. The optimum option will be a complex with the possibility of automatic regulation of pressure, which will be independently adjusted to the features of the network. The second factor is related to reliability. There are several indicators of reliability, according to which the station for increasing water pressure for private houses and apartments is estimated. Among them, we can mention the material of the hull, the presence of protective systems, as well as a thoughtful design, which initially minimizes the wear of the element base. The third aspect of the choice of such stations is due to economic considerations. Systems designed for long-term operation should provide for balanced energy consumption.

Conclusion

Rising stations should not be considered as a mandatory addition to any water supply pipeline. Moreover, not every system requiring high-pressure maintenance needs stabilization due to auxiliary mechanisms. Conversely, the simplest networks with a small number of fence points, even with minimal requests, may need a station to increase water pressure. Household systems of this type equalize the pressure indicators where the circulation initially is not capable of providing sufficient head pressure. Again, in some cases, it is possible to dispense with typical pump equipment with monitoring sensors. For example, standard circulation pumps can easily cope with the task of normalizing the head. The problem is only that their design, unlike boost pumps, is not designed specifically to compensate for pressure at low water consumption - as a result, there is a risk of premature failure of the working mechanisms.
