Household pump to increase the water pressure in the apartment. How to choose a booster pump

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

Features of booster pumps

The standard household organization scheme involves the use of a pump supplemented with a pressure sensor. The disadvantage of this solution is that the pressure increase indicator must be triggered each time a pressure deficit is detected. If initially the circulation of water meets the requirements of consumption in terms of providing sufficient pressure and "failures" occur infrequently, then this option justifies itself. But if support optimal pressure needed in the constant operation of plumbing equipment, then best solution there will be a station for increasing water pressure in a 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 system.

The main feature of such complexes is precisely the hydraulic accumulator, which accumulates not only water, but also potential energy. During operation, the liquid first enters the accumulator, and then to the direct consumer. After the resource in the tank is exhausted, the boost station gives a signal to the pump, which repeats the accumulation cycle. As a result, the same function of water supply is provided, but adjusted for pressure stabilization at an optimal pressure level.

Main characteristics of the stations

The main indicator of the station's compliance with the specific requirements of the water supply system is performance. On average, household plumbing fixtures require 0.09 to 0.13 l/s. This applies to the volumes of water with which the equipment will work, but the pressure itself, determined by pressure, is no less important. As a rule, in standard household pressure is half an atmosphere. If there is one tap, this indicator may be enough, and it is quite possible to confine ourselves to installing a typical pump with the mentioned pressure sensor. In turn, a water pressure boosting station for a private house ensures the reliable operation of several points of consumption. So, if several taps are used, then you will need a unit capable of operating at a pressure level of 1.5 atm at least. That is, additional support will raise the pressure by 1 atm. The height of the water column can also be considered as an alternative value for a suitable pressure level. The same 1.5 atm will correspond to 10 m of lifting. 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 state of the equipment. For example, it is necessary to ensure that the equipment is turned off in time and does not overheat. According to this principle, a mini-station for increasing water pressure operates, designed to service networks that are undemanding to power. Automation is more often used in productive complexes, which must have an effective system of protection against "dry" operation. The second principle of separation of equipment involves classification according to the type of cooling system. From the point of view of operating comfort, it is more profitable to use rotary units cooled by blades. These are silent stations, which also differ high performance. An alternative to such systems is a "wet" pump, in which cooling occurs due to passing water flows.

Reviews of the UPA 15-90 model from Grundfos

The system is a complex, which is based on a glandless pump, provided with a "wet" rotary mechanism. The products of the German company are often praised for their detailed and verified design calculation in terms of reliability. Station UPA 15-90 was no exception. Its device provides for the presence of a stainless steel protective sleeve separating the electric motor and the stator. The owners also note the convenience of controlling the mechanisms. Already in the basic equipment, the water pressure booster station of the UPA 15-90 modification is provided with an ergonomic terminal box, through which the owner can adjust the operating modes. Among the advantages, users include small size pumping station - this allows it to be used in household water pipes of various types. But not only the design possibilities of installation are beneficial dimensions of this model. Water supply, depending on the season or changing consumer requirements, may involve operation with a minimum level of pressure. The unit from Grundfos is also suitable in this case, since the pressure at the suction pipe 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 model described above is more suitable for stabilizing pressure in apartments and small houses, then the HWWI 4500/25 adequately proves itself in servicing country cottages. According to users, the complex's power of 1300 W is enough to service entire 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 durable metal tank, allows you to install the structure directly on the street. As for the shortcomings, many note the cost at which this water pressure boosting station is sold. The average price is 14-15 thousand rubles, which is a lot for a representative of household pumping equipment.

Feedback on the PB-400EA pump from Wilo

The developers of this station approached the design of the structure in a balanced way. This is a small unit of medium power, equipped with modern system management. At the same time, users point to the fact that the model is focused on working with cold water. The unit can be operated offline - automation, supplemented by a water flow sensor, independently controls performance. The list of advantages that a pumping station for increasing water pressure from the manufacturer Wilo also includes a low noise level and protective systems that prevent overheating and dry running.

An indicator of the quality of the water supply system, both centralized and autonomous, is the pressure indicator. To measure it, specialized pressure is used (mainly to adjust the pressure when connecting household appliances - a washing machine or dishwasher, boiler, gas hot water supply or as part of a heating system).

Sometimes the pressure is so weak that even without the use of instruments everything is clear. To correct the situation will help increase the pressure in the system when connected.

1 Features of use

Pumps for increasing water pressure in an apartment or a private house are a special category of pumping equipment. Cold water and hot water systems consist of a network of pipelines, the free movement of water through which is determined by the level of pressure in the system.

According to the standards adopted in Europe, this indicator should be from 2.5 to 4 atmospheres, depending on the length of the system and the average daily load on it. The intensity of the pressure also affects the number and type of equipment used. For example, a pressure of 2.5 atmospheres is sufficient to connect. And to connect a shower cabin, jacuzzi or heating systems - 3.5-4 atmospheres.

The water pressure in the apartment, as a rule, is 3.5-4 atmospheres. But this does not mean that more comfortable living conditions will have to be abandoned. efficient and inexpensive solution are pressure boosting pumps for water in apartments. With the development of multi-storey construction, cases have become more frequent when water does not flow to the consumer due to the length of the riser being too long and the pumping station used in the pipeline configuration is not able to raise the water to the required level. In this case, an alternative for the pump to the apartment will be.

The same situation is in suburban and cottage buildings. In them, the water supply system is often autonomous, and one, even characterized by increased power, the pump does not always provide the proper flow rate. It will not pump water with due efficiency even if mistakes were made during the design or installation of the system.

A water pump that increases pressure is also used in industry. These are large-sized models of a backup type that allow you not to stop production processes in the event of an emergency shutdown of the system or a decrease in the water level in the water supply.

2 Device, principle of operation

As a rule, a pressure-boosting water pump, including a household one for an apartment, turns on automatically when a critically low pressure level is fixed. They differ in type of construction and purpose.

2.1 Types and differences

According to key operational and production parameters, the water pressure booster pump is divided into 2 main categories:

circulation pumps to increase the water pressure in the apartment;
self-priming pumping stations.

Due to the universal simple design, the circulation pump for increasing water pressure is considered the most popular, the pump for increasing water pressure of this type is easy to install and provides optimal performance traffic intensity within the system. It is compact and intended mainly for adjusting the performance of heating systems and.

The unit consists of a compact motor that drives an equipped rotor. By forcing the water circulation rate, the pressure rises in the entire system. There are models on the market for cold water, and for hot. Pumps of the first type are cheap due to the use of durable but inexpensive plastic in the production process. They can work in a temperature environment not exceeding +40 ° C.

The second type of pumping equipment - stations - is more complex and productive. The key difference from the circulation equipment, which crashes into any fragment of the network and does not affect its autonomy, the pumping station completely cuts off the system from external source make-up. However, it is this installation that allows you to increase the water pressure to the required level.

The design consists of a surface pump powered by a hydraulic accumulator, equipped with a self-priming mechanism. Such a unit is guaranteed to improve the quality of water supply even if, by definition, water is not available on the upper floors of the building for technical reasons. The pressure level is regulated and maintained at the level set by the adjustment parameters of the relay using a membrane-valve system.

2.2 Key features

When choosing a model, we recommend paying attention to the information provided by the manufacturer, since not all units are universal. In general, to select a pump or pumping station, it is enough to pay attention to the following characteristics:

type of aircraft system - hot or cold;
the power of the device, determined by the water intake capacity, the height of the water rise and the maximum value of the pressure increase;
pressure and flow;
temperature Range;
energy consumption parameters;
productivity (amount of pumped mass per unit of time);
the direction of the axis along which the working bodies move;
start type (mechanical or automatic);
motor cooling method;
generated noise level;
material for the production of the body and nodal connections.

3 Notable manufacturers

The corresponding market segment is extensive - it presents equipment from both domestic and foreign manufacturers.

The leader is products, in particular, 15-90 / UPA15-90N. The advantages include low weight and size, ease of connection to the pipeline. With relatively low power, they increase the pressure level by 1.5-2 atmospheres, are made from high-quality durable materials (cast iron and stainless steel, respectively) and practically do not create noise. Both units are equipped with a switch that allows you to adjust the operating parameters using manual or automatic settings.

The German brand Wilo produces pumps equipped with a flow sensor, mainly with a wet type of rotor cooling. Popular models are PB 088-EA, PB-H 089 EA, PB 201-EA and PB 400-EA in cast iron. The benefits of this brand include:

easy installation due to fastening with nuts;
thermal protection of the motor;
small power consumption;
compactness;
low noise level;
corrosion resistance.

Chinese pumps WESTER WPA 15-90/20-120 have proven themselves reliable technology in the available segment. You can use them in equipping apartments, country houses and cottages. Each of the models operates in one of the three provided modes in the temperature range of +6 ... +60 ° C, has a small consumption and raises water to a height of up to 9 m.

4 Connection rules

Installing a pressure booster pump is simple - you can handle it without the involvement of specialists. It is most effective to perform a cut at the entrance.

Circular pump installation:

the product crashes in a single position according to information from the manufacturer;
when starting work, make sure that the water supply system is turned off, there is no water in it;
cut the pipes, connect and fix the pump, treat the joints with a moisture-resistant and heat-resistant sealant;
connect the unit to the mains;
test the installed pump.

Pumping stations also crash into the system, but this process is best left to specialists. The complexity of the installation lies in the fact that in addition to tapping and connecting the pump, it must be correctly assembled and the inlet / outlet hoses connected. Labor intensive and demanding practical experience is the process of setting up a pumping station.

4.1 Installation in the apartment of a pump that increases the water pressure GPD 15-9A (video)

When you open a tap in your home to simply drink water, and a sluggish trickle flows from it, then the idea immediately comes to your mind to install in the water supply line.

The sufficiency of water pressure in the pipes is the key to the normal life of a person living in a private cottage, in a country house or in a high-rise apartment. This is very important for the trouble-free operation of domestic hydraulic machines and plumbing fixtures. This is one of the very important conditions your comfortable living and the durability of expensive water equipment in your home.

For the normal operation of the main models of household hydraulic machines and plumbing units, the water pressure in pipelines from 2 to 4 bar is sufficient. If at the outlet of the intake taps you periodically or constantly lack these indicators, then you should understand the reasons for this shortage and, if necessary, install booster pumps in your individual or collective use.

Below we will describe the basic requirements for checking the performance of your water supply, the criteria for choosing the appropriate equipment, consider Various types pumps for increasing the pressure of water in the mains from different manufacturers.

Key questions covered in this article

We read the instructions and install the pump.

Comparative scale of technical characteristics of water pressure in pumps of various types

World pump manufacturers use for pump head characteristics different types the following water pressure units:

For quick approximate household calculations, the approximate ratios of these quantities are suitable:

In practice, for the normal operation of household hydraulic equipment with automation, the use of flow taps and the operation of bathrooms, work geysers and boilers, it is enough to maintain water pressure in pipelines within 2-4 bar for all major models of domestic water devices.

Possible reasons for the lack of water pressure in the mains

The lack of water pressure in your pipelines for high-rise apartments can be due to several reasons:

Daily fluctuation of water pressure in the water supply due to the frequency of use of the resource by the residents of the house;
Lack of design capacity of general user pumping equipment from the service organization;
Temporary deposits of rust and salts inside the pipeline, clogging the body of the water riser:

Clogged water cleaning filters in the water supply connection system:

In such cases, neighbors on the floor and residents of the upper and lower floors should be interviewed. apartment building to find out what water pressure is usually in their apartments. In this way, you can identify the local cause of low pressure in your particular case. It will already be possible to make the right decision to fix these problems or stop at the option of buying a high pressure water pump individually or common use, having coordinated this issue with other residents of the entrance (riser) of the high-rise building.

In a private house, these causes are of a similar type. But there may be various additional reasons for the low water pressure in your pipeline:

Long distance from the main water supply pump;
Excessive elevation of the structure and location of the flow valves above the level of the pump installation;
Discrepancy between the pressure data of the power plant, with a specific layout of power and consumable units, and so on.

Types of pumps for increasing water pressure in pipelines

In practice, it is possible to increase the pressure in the water artery using 2 well-known types of pumps:

Insertion into the water supply line of a circulation pump with a wet or dry rotor;
Installation in the line of an additional self-priming power unit or an automatic pumping station based on this type of pump.

Approximate connection diagrams for various types of pressure booster pumps:

Circulating electric pumps help in cases where it is required to increase the water pressure in the pipeline with a stable supply, but a low pressure, reaching no more than 1 - 1.5 bar. In multi-storey buildings, using this type of pump, it is unlikely that it will be possible to create a sufficiently stable pressure for all residents of the riser, even if you install 2 or more pumps. This option is more suitable for an individual increase in water pressure in a separate apartment. This is, so to speak, a "home" version of pressure stabilization.

For this reason, in apartment buildings high-rise, it is better to use self-priming pump more productivity or a pumping station with appropriate automation for water pressure with its own hydraulic accumulator.

With this option, you will not bother with the problems of turning the pump on and off, automation will do it for you.

When installing any type of pump, it should be borne in mind that if there is temporarily no even the smallest water pressure in the taps of a high-rise building on the upper floors, then installing a booster pump will not correct this situation. The pump needs at least a minimum water pressure that meets the technical limits to raise it to the desired level.

If you have installed any booster pump only in your apartment, then keep in mind that it will create a discharge effect in the common pipeline before it. And air will be sucked into this rarefied space. It is good if the pump is automatically protected from dry running and its engine does not burn out, but it will constantly turn off. In doing so, you create an even greater pressure drop in the common water supply pipe. If other residents of your entrance or riser follow your example, then this will lead to even more disastrous results with water and real “sanctions” from the water supply organization.

Self-priming pumps are limited by the amount of water rise along the height of the installation from the water table to 7-8 meters (maximum 12). A large tank for a circulation pump with a supply of water, you also cannot install in a medium-sized apartment. We will have to negotiate and cooperate with neighbors in order to install such a container in the attic of the house.

The most competent and comprehensive solution to these problems can be the installation of a full-fledged automatic station with a self-priming centrifugal pump. The power device must be of high performance. Keep your own accumulator of the maximum possible volume and full automation water supply process. You can connect this station to the basement collector of the common riser of the general water supply or to offline source. This is the only way to create the required water pressure at the outlet of all taps and not aggravate the situation for the neighbors.

Choosing a water pressure booster pump

Circular pumps are divided into 2 groups:

We are used to considering circular pumps only as elements of heating systems. But they have a wider application.

Household pumps wet rotor. They are more compact and silent in operation. They do not require preventive maintenance to lubricate moving parts, as this is done by washing the rotor shaft with water. They are easy and simpler to mount directly into the water supply pipe using a tie-in and do not require additional fasteners. But this group of pumps has low productivity and low head performance. In addition, these units are installed with a horizontal axis of the motor rotor.
Circular pumps with a dry rotor have an asymmetric housing shape towards the electric motor. They are cooled by a jet of external air from a special impeller. Requires additional wall mounting. They have better technical capabilities in terms of pressure and performance. They require regular lubrication of rubbing parts. They make quite a lot of noise while working.

Both groups are suitable for cold and hot water but require constant manual control on/off mode.

To save yourself from this, you need to pick up a circular pump equipped with a water flow sensor. Then the pump will start only when the flow valve is opened and there is water in the line.

The same effect can be achieved by installing a separate flow sensor on any group of circular pumps. And if the pressure in the system is unstable and there is insufficient water in the water supply, an additional pressure switch will need to be installed.

Some popular models of circular pumps from global manufacturers: Grundfos (Grundfos):

Jemix circular pumps W15GR and WP series:

Pressure booster pumps from the Wilo brand of the PB and PW series

Self-priming centrifugal pumps can work with increasing water pressure, both independently and as part of automatic pumping stations.

Specialized stations for boosting water pressure from main water pipelines brand Dzhileks VODOMET M are used for tie-in into the underwater part of individual sources. They have an additional flow-through filter unit for supplying already purified drinking water:

Specially created pumping units water pressure booster from Grundfos: CMBE 3-62, 5-62, 1-44, 1-75, 3-30, 3-93 and others:

Read the instructions and install the pump

To solve the problem with the water supply, you should not chase after some exorbitant indicators in terms of pressure and pump performance. You just need to add some 1.0 - 1.5 atm to the existing pressure (10 - 15 meters above the outlet tap).

So you should not have questions about how to choose a pump, what characteristics it should have. It is enough to look at the instructions for this product or listen to the recommendations of the technical manager of the store where you decided to buy the unit. The descriptions of the pumps contain all the data on their connection to the water system (connection diagram), there are rules for installing a specific product and it is described what and how to connect in the desired sequence.

IN last resort, we turn to qualified specialists for practical help for installing and configuring a pump at your dacha, cottage or high-rise building.

You can learn more about the principle of operation of the listed pumps, how their automation works, from the articles on our website in the heading: or by calling our consultant.

Quite often, the subject of complaints from residents of any private house or multi-storey building is low water pressure in the network or simply its absence. The optimal solution to this common problem is a booster pump.

This device stabilizes the pressure in the system and will make it possible to provide acceptable living conditions, because without it it is impossible to imagine the functioning of either the shower or the shower.

1 Basic information

Over time, the old standard underwater lines lose their capacity, as a result of which they cease to provide residential buildings with the necessary level of water pressure. A booster pump or a pump to increase water pressure will, by the way, be in such a situation; they are suitable for both cold and hot water supply systems.

The technique compensates for the lack of pressure so that household appliances can work normally. For example, a dishwasher / washing machine “pulls” at least 2 atm., A shower stall requires at least 4 atm. Household plumbing does not give the required value, often you will not get even 1.5 atm. (minimum pressure).

Most often, designs are used, the operation of which occurs in manual mode (manual pumping pump) or automatic. The manual pumping pump provides for the operation of constantly on pumping equipment. Automatic is preferable and more economical, because it protects the mechanism from working in the absence of water, increases the service life. He is responsible for operating the pump using a water flow sensor.

Pumping units are installed in private houses, apartments, haciendas, cottages. The main condition for their smooth operation and reliability of operation is correct connection water and electrical systems.

1.1 The principle of operation of pumping devices, basic parameters

The main parameters to pay attention to:

switching mode - automatic / manual;
degree of pressure;
size. As a rule, all units are compact, which simplifies their connection to the main pipeline;
noise level. Due to the principle of operation, booster pumps operate almost silently, which allows them to be installed in apartments;
case material is an important parameter, which determines the level of noise emitted during operation, and Maximum temperature water. Stainless steel- material of execution, providing resistance to corrosion, strength.

The principle of operation of booster pumps for water is to increase the pressure in the water supply network by the equipment system, depending on the pressure in the water circuit. The mechanism takes liquid from a low-pressure pipe, then raises it to the required value, and then delivers it to the flow point.

If you are a tenant of an apartment located on the upper floors, and the centralized water supply is "suffering", better advantage give the device with a hydraulic accumulator (storage tank) - a pumping station. This is a unit that creates pressure in front of the points of water analysis, equipped with control devices and shutoff valves. The devices are used as large standby installations in industrial purposes, life. Mounted between the water source and the water supply.

2 Advantages and purpose of booster pumps

Pumps that pump water are used to increase the water pressure in front of the points at which the water is parsed. In other words, a booster pump is used in cases where the water pressure in a residential area is lower than desired. To do this, the device is connected to the central water supply system.

In the industrial field, booster pumps are also used, but the dimensions of such installations at enterprises far exceed the dimensions of products designed to increase pressure in living conditions. At the same time, the booster pump in industry is often operated only in cases of emergencies, for example, when there is a need for fire fighting.

The advantages of such units include:

compactness;
low noise level during operation;
the ability to pump water with high power;
relatively cheap cost;
reliability.

2.1 Characteristics and types

This type of equipment is divided according to the type of design, and therefore, devices that have different designs may differ significantly from each other. In particular, according to the type of device, pumps that increase the pressure can be in the form of self-priming pumping stations, or they can be made in the form of circulating products that increase the pressure level in the pipeline.

Self-priming units consist of a hydraulic accumulator and a surface pump, which has the function of liquid suction. Such equipment is capable of lifting liquid, including in cases where it does not reach the floor on which you live at all. The water accumulator performs the function of adjusting the level of pressure in the plumbing system. This is achieved by the check valves and the air membrane that the device is equipped with. Pressure adjustment is carried out by means of a relay installed in the accumulator, which, in particular, is responsible for automating the entire process.

3 Selecting a booster device and installing it

When choosing pumping equipment for your apartment, it is recommended to proceed from the specific parameters and characteristics that a pump must have that can meet your needs. It does not hurt to consult with professionals before buying a device, as well as consult with those who already use such equipment.

The first thing to do is measure existing level pressure, which will help you with an understanding of how much power a future purchase should have. This is important because you can buy, for example, the most powerful pump, and it will naturally increase the pressure in your pipes, however, it may be enough to purchase a product with less power, which will also cope with its task, but at the same time you will not overpay for either the device itself or the electricity that it will consume.

Installing and connecting booster equipment is not a very complicated process that requires special knowledge, skills or tools. In most cases, the pump just needs to be inserted into the pipe, which is located at the entrance to the water supply system. Circulation products cut into a certain section of the pipe, then they are sealed with high quality and tightly twisted. When installing circulation modifications, it is important to install the pump in correct position, which must be indicated by the manufacturer on the packaging, or in the instructions for the device.

Suction pumps are more difficult to connect, since for installation you must first assemble the device itself, as well as run the inlet and outlet hoses to it, and then connect the hydraulic accumulator to the unit. At the same time, pumping stations, as well as circulation pumps, crash into the water supply system. All these procedures require high-quality adjustment, which can only be guaranteed by experienced people. However, some self-confident users connect the pumping station on their own.

3.1 Installation in the apartment of a pump that increases water pressure GPD 15-9A (video)

Plumbing - part engineering networks private houses and apartments. Because of low pressure in pipes, residents often receive insufficient water. This situation limits the possibility of using two plumbing points at the same time, and washing and Dishwasher just don't turn on. The only way to make a difference is with a pumping station designed to increase water pressure. The power and performance of the installation is selected individually. The compact device is able to normalize the level of pressure and maintain an optimal indicator.

For urban water supply network accepted GOST standards assume a pressure of 4 atmospheres. Such an indicator is rare, seasonal changes in water consumption make it fluctuate in the range of 2.5-7 atmospheres. Normal work of the soul, washing machine and sinks will provide a parameter of 2 atmospheres, a jacuzzi or watering the garden will require raising it to 4. In reality, the pressure is often 1-1.5 atmospheres, excluding the stable operation of plumbing equipment. High pressure is also a negative factor, it negatively affects the network elements, leading to their rapid wear.

The problem of insufficient water supply is faced by residents of apartments on the upper floors and owners of private houses in the summer. First of all, it is necessary to exclude the possibility of clogging of pipes or their overgrowth. lime deposits. If the problem is not in the diameter of the pipes, then the installation of pumping equipment will radically solve the issue. Pumping station raise and stabilize the pressure in the system.

Classification of pumping equipment

A budgetary way to increase the pressure in the water supply system of an apartment or a private house - installation pressure pump. Devices can be divided into main groups:

manual - after being connected to the power supply, they are constantly in working order. 24/7 operation leads to rapid wear. If there is no water in the system, the device may burn out;
automatic - the design provides for a sensor that turns on the unit when the fluid moves. This option will cost more, but will last longer. The equipment is designed to pump clean water, so it is better to equip the system with a coarse filter. The low weight and dimensions of the pump allow it to be installed directly on the pipeline.

The pump motor is cooled in two ways:

the flow of passing fluid;
fan mounted on the motor shaft.

On the basis of water-lifting pumps, stations for increasing water pressure are produced.

If the liquid in the pipes is often completely absent, it will be necessary to upgrade the system and install a self-priming mini pump station. This compact device is able to increase the pressure and keep it at a given level.

Equipment design includes:

storage tank of membrane type (hydraulic accumulator);
centrifugal pump;
system control relay.

The system automatically supplies water to fill the tank. The consumer uses the liquid accumulated in the accumulator. The main advantage of such a system is the prevention of pressure surges in pipes. In addition, the mini station provides a supply of fluid in the accumulator, which can be used at any time.

With a drop in the water level, the pressure in the system decreases; at a given indicator, the relay turns on the pump again. The number of inclusions and the life of the pump depends on the volume of the tank, the larger it is, the less often the electronics that bring the unit into working condition are triggered. The area of the apartment is limited, so it is problematic to find a place for a volumetric tank, in addition, the absorption of water by the equipment leads to airing the system. Installing a pressure boosting station without the permission of the public utility is illegal, and it will not be easy to get approval, so installing a booster pump is preferable.

How to choose the right unit

Among the main criteria for choosing a mini station to increase the pressure in the system:

Productivity - the amount of water that the installation pumps per unit of time (minute, hour).
Power - is selected based on the number of consumers. A high score is not always a plus. The station sucks water from a source (well, pipeline), if the pump runs faster than it is being filled, then the unit may be left without liquid and overheat.
Compliance of the model with the cross section of pipes in an apartment or a private house.
Maximum lifting height. This indicator is important for the use of equipment for autonomous water intake of a private house and for pumping water to the upper floors of an apartment building.
Unit size. The dimensions of the station, including the accumulator, must correspond to the area of \u200b\u200bthe room where it will be installed.
Noise level. This criterion depends on the cooling method, the "wet rotor" works silently, and the "dry rotor" is noisy due to the fan blades.
Range allowable temperatures. Devices can be for hot, cold water or universal.
Installation type - vertical or horizontal, the choice depends on the characteristics of the room.
Manufacturer's reputation. Products of unknown companies are distinguished by an attractive price, but their quality is doubtful, and there are no service centers. It is better to buy high-quality and reliable equipment from a manufacturer with positive reviews.

Notable hardware manufacturers

DAB offers a compact station for installation in an apartment or house with electronic control E.sybox mini. It is distinguished by the absence of noise and vibration, provides a constant pressure in the pipes, and is easy to install. Lifting height - 8m, productivity - 80 l / min, membrane tank per 1 liter The mini unit is easily placed under the sink.

The model of the German company Wilo PV-088 EA is mounted on metal pipes hot and cold water supply. The maximum head lift is up to 8 m, it works in manual and automatic mode. The mechanism is cooled by fluid flow. Low noise level allows you to avoid discomfort when placed in an apartment.

The Grundfos UPA 15-90 pump operates in three modes: Automatic, Manual, Off. The automatic mode is controlled by a built-in sensor. Manual mode involves constant operation, so you need to monitor the presence of water in the system. The unit is characterized low level noise and light weight. Its capacity is up to 1.5 cu. m / h, working temperature– 60º C.

Unlike the listed models, the Jemix W15GR booster pump operates on the “dry rotor” principle. The mechanism is cooled by a built-in fan. This design is more productive, but creates noise during operation. It has three operating modes: "MANUAL" - manual, "AUTO" - automatic, "OFF" - off. Provides head lift up to 10 m, productivity - 1.5 cubic meters. m/h

Mounting the booster pump

The installation of pressurization equipment begins with shutting off the water. The work includes the following steps:

The length of the pump is measured along with the fitting.
At the installation site, the length of the section is marked and the pipe is cut out.
From the outside of the resulting ends, a thread is cut.
Adapters of the required diameter are installed, a fitting supplied with the pump is screwed to them. On the body of the equipment, the arrow indicates the movement of the flow, it is important to install it according to the given direction.
To install a separate outlet, a three-core cable is pulled. Grounding is mandatory, and the connection is made through the RCD.
The water opens and the pump is tested to see if it works. If the connection of the fittings is not tight enough, wind up the FUM tape.

DIY station

If there was no device with the necessary parameters on the counter, you can make it yourself from components with the desired characteristics. The pressure boosting station consists of a small number of components and parts, it is enough to purchase a pump, a hydraulic accumulator of the required volume, and an automation unit. A 50-liter storage tank is suitable for a family of three; stagnant water is also undesirable.

The control system should include:

smooth start of the pump;
dry running protection;
overload protection.

During installation, all elements of the water pressure increase station are installed in one place.

Tips for choosing and installing a mini pumping station

Give preference to the model check valve, this design increases the safety of the equipment.
Choose a station with a built-in filter, it will protect parts from foreign particles. When clogged, the element is removed and washed.
To place the equipment you need warm room, otherwise when negative temperature the water in the accumulator will freeze.
To carry out preventive maintenance without problems, install a shut-off valve before the pump.
