How does a booster pump work? Recommendations for the selection and installation of pumps to increase water pressure. Boost pump E.SYBOX

A pump to increase water pressure is needed when there is low pressure in the water supply networks in order to make the liquid supply stable. The water pressure booster pump is produced by many manufacturers, so the consumer is often faced with the task of choosing such a unit according to certain criteria that correspond to the specific conditions of the water supply network.

What indicators should be used to select a pump?

A pump that increases pressure, like any other technical device, has certain characteristics. The main ones are the minimum inlet pressure and the maximum value that the booster pump provides for the water supply. The standard pressure that water should have in household pipeline networks is 4 atmospheres. But in real conditions, this figure can reach 7 atmospheres, which has a very bad effect on any plumbing and pipelines.

If the water in the pipes has less than 2 atmospheres, then no device such as a washing machine or jacuzzi will work. The minimum value of this parameter for the operation of the entire water supply system is chosen within 2.3 atmospheres. Some pressure boosting pumps have values ​​expressed in meters of water column in their data sheets. When purchasing a unit, you must take into account that one atmosphere is equal to 10 meters of water column. For systems fire safety 3 atmospheres are taken as the standard. According to all of the above, pumps for increasing pressure must provide a working water pressure of 2 to 4 atmospheres at the outlet with fluctuations in this parameter at the inlet from 1.5 to 2 bar.

Types of units for flow stabilization

Such a pressure boosting pump is a flow-through apparatus, the operation of which creates additional force, sharply increasing the fluid pressure at the outlet.

1. There are several types of pumps that increase fluid pressure in a pipeline:
2. Household pumps for creating water flow in a private house or increasing water pressure in an apartment on a high floor.
3. A garden pump capable of lifting water from a deep well and used for watering plants in a garden or vegetable garden.

All types of pumps have two operating modes:

1. Manual control that allows you to implement the mode continuous operation. At the same time, the person himself ensures that the unit does not overheat, and, if necessary, turns it off.
2. Automatic control is based on the use of a flow sensor, which turns on the pump only when the consumer's tap is opened. This mode is more economical and the equipment lasts much longer.
3. The units are cooled by a fan impeller or a flow of pumped liquid.

The pumping station includes a centrifugal unit capable of increasing the flow of water so much that the module can pump it out of itself. deep well or increase the fluid flow rate so that it reaches the top floor of a high-rise building with the required parameters.

To obtain high-pressure liquid when the flow is unstable, a hydraulic accumulator is installed in the station, increasing the pressure in the water supply. The consumer receives water from its tank when the pressure switch turns off the centrifugal pump when the supply of liquid from the central network stops.

What should a consumer consider when purchasing a pump?

When selecting, you need to focus on the following parameters:

1. The pressure created by the unit and its throughput.
2. Dimensions of the room or site on which the pumping equipment should be located.
3. Reliability of the pump from the manufacturer whose device the buyer wants to purchase.
4. Financial capabilities of the consumer himself.

Before you go to purchase the desired pump, you need to contact a specialist who will carry out necessary calculations according to the performance of the unit and the required pressure. Such things cannot be decided by eye. Most pumping equipment manufacturers provide such services almost free of charge.

If a person only needs to increase the pressure in the pipeline by 1.5-2 bar, then many companies for this purpose produce compact pumping devices that fit directly into the water supply pipe.

If possible, then instead of one big pumping station You can purchase several small units of lower power, which are usually turned on right before the liquid entry points and various household appliances; their operation should be optimized as much as possible.

You can purchase pumping units at construction markets and in various stores. It is better to go to special branded centers. There the choice is much wider, and it is possible to get free advice on pump parameters and their installation, as well as warranty service.

Boosting pumps water in the water supply system refers to household pumps. They are in great demand nowadays. Often, due to low water pressure, various household appliances may not work, or it is simply difficult to take a shower or run a bath. What can we say about such an important matter as washing dishes?
This device is a real solution to the problem of water pressure in a city apartment or in a private house - it increases the water pressure in the system to the required level and stabilizes it.

The presence of a pump that increases the water pressure in the apartment is a great advantage, because such household appliances as geyser, dishwasher, washing machine work without failures or breakdowns only if there is stable water pressure.

Quite often, residents of high-rise buildings and private houses are faced with the problem of insufficient pressure in the water supply. For this reason, work becomes difficult, and. To ensure normal pressure, it is necessary to install a pump to increase the water pressure in the apartment. Together with the experts of the online magazine site, we will consider the varieties, features of choice and self-installation equipment that increases water pressure.

It is known that water main systems contain a large number of branches and bends. This results in a pressure drop that is significantly lower than the values ​​set in regulatory documentation for urban networks. Low water pressure in most cases can also be due to wear and tear on the pumping equipment.

So, the pressure power must be at least 4 atmospheres. In practice, this figure is much lower. The table shows some values ​​of the pressure standards of the water supply system for the operation of household appliances and other equipment.

Table 1. Minimum operating water pressure indicators for household appliances

Boosting water pressure equipment is also installed in cases where the pressure at different points of consumption within the same apartment differs, or there are completely no comfortable living conditions (water flows in a thin stream constantly, there is no way to turn on the heating, etc.).

Advice! Not in all cases, the problem with the pressure of cold and hot water can be solved using pumping equipment. Very often it is too low due to a clogged water supply system or a breakdown. Before buying a pump to increase water pressure, you need to make sure that there is no emergency situation, and, if necessary, eliminate it or replace the damaged section of the highway.

Classification of high pressure water pumps

By type of control

Many people do not know how to increase water pressure in an apartment and choose the right booster equipment for these purposes. First of all, you should know that devices for providing the necessary pressure differ in the type of control.

They can work in automatic and manual mode. In the first case, a water flow pressure sensor is installed in the pump, which regulates its operation. As soon as the tap opens, the pumping unit turns on. You should know that such equipment is much more reliable than manual analogues, since it has protection against switching on in dry mode (in the absence of water pressure).

As for manual installations, they operate in continuous mode. This requires periodically monitoring the equipment and, if necessary, turning it off to avoid overheating. A significant disadvantage of such stations is the short service life of the mechanisms.

Hand pumps usually cut into the pipeline and. If you open the valve, the contacts will operate, which turn on the power to the pumping device. In turn, this leads to an increase in pressure in the main line. There is also flow units, which are mounted directly to the point of water intake or in front of various types techniques to enhance their work.

According to the permissible water temperature in the pipes

Almost every pumping station for increasing pressure in the main line is designed for a certain operating water temperature. It cannot exceed 60°C. The pump is connected to the apartment wiring, increases the pressure in the system, after which the water is heated, if necessary, using, and other settings. Among the pump models, there is equipment that operates from a cold or hot water supply line. There are also universal station designs that operate regardless of the type of connection and liquid temperature.

By type of engine cooling

Since electric motors are used to change the force of water pressure in the lines, this requires the use of cooling systems. Pumping devices are available with a “wet” as well as a “dry” armature. In the first case, the equipment is small in size and is installed directly on the main pipe.

“Wet” pumps, unlike their “dry” counterparts, operate almost silently, since during pumping water the rotating parts of the mechanism are lubricated. If the injection compressor has a “dry” armature, its shaft is equipped with an impeller, thanks to which the housing is cooled by air. Such pumps are characterized by increased productivity, and they are used if it is necessary to provide normal pressure simultaneously for several water intake points (consumers). It is important to know that the design of “dry” pumps is fundamentally different from other types. The rotor of the device is located outside the structure of the unit, and it also has a separate air cooling system. In this case, the interaction of the electric motor armature with the aquatic environment is completely eliminated.

What technical characteristics should you pay attention to when choosing a high pressure water pump?

Power

To correctly buy a pump that increases the pressure in the water supply, you should pay attention to its power. It is this indicator that determines the device’s performance and capabilities. When choosing models, you also need to know that high-power equipment in apartments is not always justified.

If you need to install auxiliary equipment for an apartment, it will be enough to purchase a pump with a power of up to 0.25 kW. This technique uses energy sparingly and copes with the assigned tasks perfectly. If the home is large and it is necessary to provide water supply to several points simultaneously, you can use installations with a power of up to 0.5 kW. In private homes, as a rule, they use 1 kW and above.

Water rise height

Each pressure booster installation is designed to supply water to a certain height. This point should definitely be taken into account when choosing a model, especially if it is to be installed on the upper floors of a high-rise building. This indicator can be obtained from product sellers, which is indicated in the technical data sheet of the equipment.

Size

The dimensions of the pumping equipment also play an important role when choosing a model. Many people, in order to save space, prefer to install compact devices. If there is no pipeline and there is no accident in the line, but there is no pressure, you should think about purchasing a self-priming pumping station with.

Noise

When choosing a pump model, you should pay attention to the noise level of the equipment. For apartments, you can purchase an installation with a “wet” rotor, which will operate almost silently. If you manage to install the pumping station in the attic, then you won’t be able to hear the unit turning on and off in the rooms.

How to increase water pressure in an apartment

When to choose a water pressure booster pumping station

A pumping station may be required if water does not flow to the top floors of high-rise buildings. This equipment is also used for installation. The station is a centrifugal equipment designed to increase and stabilize water pressure in pipelines. The tank has a reservoir of a certain volume, which is filled by means of a pump. As soon as the water supply in it runs out, the relay is activated and the liquid enters the accumulator. In practice, it has been established that the larger the volume of the tank, the more reliable the equipment operates, since the installation is turned on and off infrequently.

Why should you choose a water-cooled pump for your apartment?

Many people prefer to install water-type cooling units in their apartment. This is due to the fact that pumps that increase water pressure in a water supply system with a “wet” anchor have compact dimensions, have a low noise level and are easy to maintain.

In addition, connecting this equipment is not particularly difficult. First, a piece of pipe of a certain length is cut out of the supply line, after which a unit is installed, which operates on the principle of flow-through pumping equipment. The installation is carried out directly in front of the point of water intake or equipment (, etc.) to ensure the required pressure for its operation.

Video “Features of installing a circulation pump with your own hands”:

Let's consider the features of conducting installation work using the example of a circulation pump. Connecting the unit is not particularly difficult, so you can do this work yourself. First of all, it is necessary to insert the unit at the inlet of the water supply system.

After measuring, it is necessary to cut a piece of pipe of the required length from the water supply. Before proceeding with installation, turn off the water supply.

Advice! The unit must be inserted in the position recommended by the manufacturer.

The pump must be installed on a prepared section of the water supply system, for which water shut-off valves, fittings and other connecting elements should be used, which are selected depending on the selected scheme. It is recommended to treat the threaded connections with sealant.

Upon completion of installation, you need to connect the pump to the electrical network in accordance with the recommendations described in the manufacturer's instructions. It is extremely important to follow safety regulations to avoid injury.

After installation work, it is necessary to test the operation of the unit and evaluate the quality of water pressure. If necessary, eliminate assembly deficiencies and repeat the test.

Perhaps the main parameter in modern life is the level of pressure. A comfortable level of water pressure in the pipes allows us to operate the entire system without any problems. If there are problems with this in the water supply system, then they automatically affect its performance characteristics.

But what to do if there is not enough water pressure in the water supply? The answer is very simple. Install pumps to increase pressure.

1 Features and purpose

As we all know, modern plumbing in an apartment or country house consists of several main structures or elements. Perhaps the most important of them is the pipeline itself.

Water streams flow through the pipeline to taps, which can then be obtained from any suitable location. The pressure in the system is responsible for the free flow of water through the pipes. According to European standards, the pressure in the water supply system should be at least 4-5 atmospheres.

This is explained by the necessary requirements that are provided by various additional plumbing fixtures. So, washing machine will not be able to function if the water pressure in the system is not equal to 2 atmospheres. It just won't start.

Pressure showers and a variety of Jacuzzi bathtubs require even more serious conditions. They can already operate normally if the water pressure in the water supply system is at least 4 atmospheres. Various devices for hydromassage are not limited to the stated characteristics.

As you can see, the conditions in a modern water supply system impose serious requirements. Moreover, they do not always answer them. So, in an average apartment, the water pressure in the water supply can be only 2.5-3 atmospheres. Good pressure also happens, but here everything rather depends on the quality of the equipment that serves the apartment building.

IN country houses, cottages and mansions, the situation is complicated by the fact that people have to create water supply systems there on their own. And not always one single pump is able to provide normal conditions in the water supply. Especially if the pipe laying scheme was planned incorrectly or in violation of certain standards.

There are also extreme cases when the pressure level in the water supply has not just dropped. It is simply not there, since the water does not reach the consumer. For example, if the riser is too long and the booster pumps at the inlet are not able to raise the water to a sufficient level.

2 Types and characteristics

As you can see, pressure booster pumps have different designs and in this parameter they differ very seriously from each other. First, let's look at their main division by type of design and purpose. According to these parameters they are divided into:

• increased blood pressure;
• Self-priming booster pumping stations for water supply systems.

The first type is a standard booster pump. It is called circulating because it promotes the circulation of liquid in the pipes. The device is usually small in size and very compact. It is cut into a certain section of the pipeline, which increases the pressure level and the speed of fluid circulation.

Initially, these pumps were conceived for arranging hot water and heating systems. This is explained by the serious length of the heating circuits, as well as their resistance at the junction points.

Under natural conditions, the carrier simply cannot circulate normally in the water supply system, so a special pump is used to increase the pressure.

In a standard water supply the situation is similar. It’s just that here the device is used not so much for pumping hot liquid, but to stimulate the general level of water movement.

The circulator consists of a small motor that rotates the rotor part with the impeller. It is this small mechanism that is capable of pumping water into the chamber and significantly improving the performance of the entire pipeline.

The most popular pressure booster pumps are produced by Wilo. In particular, the Wilo TOP, Wilo Star-RS, Wilo Star, etc. lines.

Now let's turn to the second type of booster pumps. This is a much more serious unit that cuts off the water supply system from external replenishment.

2.1 How to choose booster pumps?

If you need to choose a household pump to increase pressure in a pipeline, you should be guided by dry calculations and specific characteristics of the equipment. To begin with, it is recommended that you contact a specialist to assess the condition of your system.

As a last resort, measure the pressure yourself. This will help you choose water pumps with optimal power. After all, there is no point in overpaying for overly powerful equipment, which in your case simply will not be able to reveal its potential.

A circulating sample for increasing pressure is worth buying if you have water, but its pressure is too weak. Moreover, to level out a deficiency of 2-3 atmospheres, one sample is enough. In some cases it is necessary to install two pumps. But this happens quite rarely.

Pumping booster stations are worth choosing if you don’t have water in your tap at all, but at a lower level in the system (for example, with neighbors downstairs, if you are a tenant apartment building) it is available.

In this case, the self-priming pump will pump liquid to your level, and the hydraulic accumulator will completely close the system and give you the opportunity to control its condition yourself.

From popular manufacturers it is better to buy pumps or Grundfos. Since Wilo companies have proven themselves in the market with the best side and time-tested.

2.2 Features and connection technology

Pumps for increasing pressure in water supply systems are quite easy to install. As a rule, they are inserted at the entrance to the system so that the stimulation of fluid movement is as convenient and efficient as possible.

Thus, circulation models are cut into pipes in a certain area. All you need is to connect the device to the pipes, seal the connections and connect the electricity. Then it remains to test the operation of the device in practice.

It is worth remembering that circulation models must be mounted in a single position. The correct position will be indicated by the manufacturer on the packaging. If you install the device by mistake, it will either work poorly or refuse to start at all.

2.3 How to install the pump? (video)

Perhaps you have ever encountered a situation where water flows from a tap in a very weak stream. At the same time, it’s inconvenient to wash dishes, and there’s no need to even talk about taking a shower. But the inconvenience, unfortunately, does not end there. If the water pressure in the tap is low, it is impossible to start gas water heater, washing and dishwasher may also “refuse” to work in such conditions. As sad as it may be, this situation is quite common. Very often, residents of the upper floors of high buildings suffer due to insufficient water pressure. apartment buildings during peak hours. Owners of private houses also often face this problem, which is explained by shortcomings in the work of public utilities. If you are familiar with the problem described, then know that it has a fairly simple solution: they will help you out in a private house.

What you need to do before choosing a pump to increase water pressure in a private home

Pressure can be indicated in different units of measurement. That is, for example, in technical documentation pump pressure can be indicated in MPa, in articles - in kPA, and on instrument panels - in mm of water. Art.

You probably won't need to know exact value pressure in the water supply system, so you can use the following ratio, which will make it easier for you to evaluate the operation of the water supply system in your private home:

1 bar ≈ 1 at ≈ 10 m aq. Art. ≈ 100 kPa ≈ 0.1 MPa.

The standards set the requirement for tap water pressure for residents of a private house or apartment - 4 bar. With this value, all household appliances in private or apartment building will be able to work well.

Unfortunately, few residents of private houses have pressure in their taps at exactly this level. Most often the deviations are significant. Any deviations from the norm are harmful to the water supply system. Thus, a pressure of more than 6-7 bar can lead to depressurization at pipe joints. A jump to 10 bar is fraught with an emergency situation.

The solution to the problem of insufficient or increased water pressure in a private house is to install a reducer that equalizes the pressure in the internal water supply, which eliminates the possibility of water hammer. If you avoid mistakes at the stage of selecting and installing the gearbox, the pressure in the system will always be optimal.

A more complex situation is a systematic lack of pressure in the water supply of a private home. It is necessary to identify the cause of this problem. Conduct a simple study to find out what pressure in the water supply of your private home is normal and how it changes during the day. After research, the situation will become clearer.

You can measure pressure with a pressure gauge. It is inexpensive, so we recommend that you purchase it and install it on the inlet main of your private home. It will be even better if you buy a mesh wash filter for coarse water purification with a built-in pressure gauge. It is enough to record the device readings 3-4 times a day at certain hours (including peak hours). Then it will be possible to analyze the water pressure in your private home and draw preliminary conclusions.

You can ask someone you know or buy your own portable pressure gauge. Connecting it is not difficult: you can do this using a flexible connection to the water sockets of faucets or to spouts, if the threaded connection is suitable. In fact, you can even assemble a simple, but quite accurate pressure gauge with your own hands.

In order to assemble the pressure gauge, you will need a plastic tube approximately 2000 mm long. The diameter of the tube must be such that it forms a tight connection with a fitting that screws onto the faucet spout, replacing the divider nozzle.

You can accurately determine the water pressure in a private house in the following simple way:

The first step is to connect the tube (vertically) to the faucet (or other water outlet). Then turn on the water and level the liquid level: there should be one horizontal line with a connection point (without an air gap at the tap - see the left figure). Now you can measure the height of the air section of the tube ( h o).

The next step is to close the top hole of the tube with a stopper (so that air does not escape) and open the tap completely. The water will rise. After stabilizing the position, you need to measure the experimental value of the air column ( h e).

Now you can calculate the pressure:

P in = R o × (h o /h e)

Where R in– pressure in the water supply at a given point; R o– initial pressure in the tube. It is acceptable to take it as atmospheric, that is - 1.0332 at; h o And h e – experimentally obtained value of the height of the air column.

It may be that the pressure at several different points in the pipeline of a private house varies. This is evidence of the formation of rust or limescale on the pipes. In this case, it is necessary to replace the piping.

It is possible that the filters used in the water supply of your private home are very dirty or too old. To troubleshoot problems, it is necessary to perform appropriate preventative measures.

Classification of pumps for increasing water pressure in a private home

On sale you will find different variants pump designs for increasing water pressure in a private house:

circulation pumps for increasing pressure;

self-priming pumping stations to increase pressure.

They are standard devices for increasing water pressure in a private home. They received this name because they accelerate the movement of water in the pipes. Circulating ones are most often small in size, they are very compact. They are installed in sections of pipelines with insufficient pressure.

The developers of pumps for increasing water pressure in a private home had a specific goal - they wanted to come up with a device to improve the operation of systems with hot coolant. This is understandable, since the heating circuits have an impressive length, and there is resistance at the node connections. Without the use of pumps, such systems will not function effectively.

If we talk about water supply, then the essence is the same, with the only difference being that the pump accelerates the movement of water, and does not pump up hot coolant.

A circulation pump for increasing water pressure in a private home consists of a motor that drives a rotor part with an impeller. Thanks to these elements, the pump accelerates the movement of water in the chamber and significantly improves the characteristics of the pipeline as a whole.

The installation consists of a surface pump and a hydraulic accumulator. A surface pump pumps water into a hydraulic accumulator, which has an air membrane and check valves, with the help of which the pressure in the water supply system of a private house is regulated and maintained at the required level.

The pressure switch allows you to adjust the value of this indicator and automates processes.

Pumps for increasing water pressure in a private house operate in the following systems:

with cold water;

with hot water.

To increase the pressure of cold water in a private home, simple plastic pumps are used. They work with liquid whose temperature does not exceed +40 °C and do not tolerate prolonged contact with hot water.

Pumps for increasing the pressure of hot water in a private home are more expensive, but can be used in heating and hot water supply systems. They are made from expensive polymers, stainless steel and high-quality rubber.

The circulation pump for increasing water pressure is not very powerful, but it also consumes very little energy.

It increases the water pressure in a private house by 2-3 atmospheres. There are more powerful analogues that pump up to 2-3 m 3 of water per hour.

Significantly more powerful are water stations for increasing water pressure, the self-priming pumps of which consume 2 kW of electricity when operating. They "attract" water from long distance(up to 12 meters).

So, when planning to purchase a pump to increase water pressure in a private house, it is important to determine why it is needed: simply to improve pressure or to raise water to the upper floors. To increase the pressure, a small, low-power pump of an “in-line” design, embedded in the pipeline, is suitable. But if you need to raise the water level, you need a centrifugal water pump high pressure with hydraulic accumulator. The operating mode of such pumps is:

Manual– in which the equipment can operate continuously. It will be necessary to monitor the temperature of the pump itself in order to avoid overheating and failure.

Automatic– in which the pump operation is controlled by a flow sensor. The pump will start the moment water flows from the tap. This ideal scheme operation, as it eliminates the need to start the pump to increase pressure in dry mode. Such a pump is more profitable because its service life is longer.

Pumps for increasing water pressure in a private home can be cooled thanks to the motor impeller or the pumped liquid. Here is a classification of pumps depending on the method of their cooling, namely:

Blades mounted on a shaft(dry rotor design). Such engines have little efficiency value, they create little noise during operation.

Liquid(wet rotor). The operation of such pumps is almost silent.

For the homeowner, the size of the pump to increase water pressure is important, since it is necessary to allocate space for its installation.

The advantage of a pump with a dry rotor is high efficiency, and with a wet rotor it is quiet.

As a rule, pumps are installed at the inlet a private house. Note that there are models that can be installed on both cold and hot water supply systems (universal pumps) or for a certain water temperature.

Pumping stations

After you check whether the water supply pipes are clogged, you can think about purchasing a powerful self-priming pumping station. Pumps for increasing water pressure in a private home can be equipped with a hydraulic accumulator. More often than not, homeowners prefer without it. However, experts advise choosing pumping stations with hydraulic accumulators.

Station is a surface centrifugal pump for increasing water pressure in a private home. It is connected to a hydraulic accumulator and a pressure switch, which controls the entire system. Using the station, water from the system is supplied to the tank. Thanks to the tank, the consumer always has a supply of water, even if it is turned off, which is very convenient. Gradually the pressure drops, and at a certain point the relay will automatically turn on the pump.

It is more profitable for the tank to be large, since there will be enough water in it for a longer time and, accordingly, starting and shutting down the mechanism will be carried out less frequently, and the equipment will wear out more slowly. A standard connection diagram for a pressure booster pump and a diagram for installing a pumping station in a private house with a nearby well are shown below. Please note that connection is possible to any available water source.

What to consider when choosing a pump to increase water pressure in a private home

When selecting a pump, consider the following:

what problem should a pump for increasing water pressure in a private house solve;

throughput pumps and the pressure it creates;

How reliable is the manufacturer;

the dimensions of the room where the pump will be installed to increase water pressure in a private house;

how much money are you willing to spend on purchasing such a pump?

If you do not know the required performance and pressure, it will be very difficult to choose the most suitable pump for your water supply system. It would be right if you entrust the calculations to a specialist, especially since it is not difficult to find one: many companies involved in the sale of such devices offer this service completely free of charge.

If you need to slightly increase the pressure (by 1.5 atm), then choose a compact pump to increase water pressure in a private home. It is very easy to install.

It can be cut directly into the pipe. Scheme:

Circulation pump.

1. Stopcock.

   Thermostat.

   Safety valve.

It is necessary to choose such a pump to increase water pressure in a private home so that its power meets the needs of the system. When the pressure is insufficient, this is bad, but excess pressure should not be allowed, since the system elements will function under conditions of unreasonably high load, which is fraught with rapid wear.

The minimum pressure in the system is 2 atm. In such conditions, you can safely wash the dishes and start the washing machine(note that some models may be “capricious” and refuse to work in such conditions).

However, if you are used to using hydromassage in the bathroom and lying in a jacuzzi, then the pressure in the system should be higher - 5-6 atm. Some techniques only work at even higher values. Thus, when thinking about buying a pump to increase water pressure in a private home, re-read the instructions for the household appliances you have (and those you plan to purchase in the future).

To obtain accurate numbers, you will need the help of a specialist. Most likely, he will have enough preliminary estimated data to carry out calculations.

Now it is important to understand what problem you want to solve by installing a pump in a private home. If you cannot take a normal shower when someone is washing dishes in the kitchen, then a regular pump will be enough for you to increase the water pressure in a private house (it will provide an increase of 2 atm.). You probably have some Appliances(the operation of which is related to water pressure), so study the instructions for it.

The devices operate normally at a certain water pressure in a private home. If the water supply system cannot provide your expensive equipment with the required amount of water, then it will have to run idle, which will most likely lead to a breakdown of the device that cannot be repaired under warranty.

When choosing a pump, take as a basis the maximum permissible pressure indicators for the equipment (data from data sheets). If you have too many of these household appliances, consult an engineer.

There is an opinion that you should not buy an expensive and powerful pump to increase water pressure in a private home. Proponents of this judgment claim that you should choose a less powerful device that is connected directly before the parsing points and household appliances, whose operation needs to be optimized.

Buying a pump today is easy, since their range is quite wide. We recommend purchasing the device not on the market, but in a company store, where there is plenty to choose from, and, which is important when purchasing expensive models, there is warranty service.

How to install a pump to increase water pressure in a private house

How to install a self-priming pump

Installation of this type of pump is quite simple. You don't need to purchase any complicated tools to install the equipment. You should follow these steps:

decide on a location for the accumulator and pump;

install a hydraulic accumulator;

install pipes to connect equipment to the water supply;

hang a pump to increase water pressure from the wall;

tie the pump and accumulator;

check the operation of the pump in automatic mode.

A pump and hydraulic accumulator with a pressure switch are a variation of a pumping station for increasing pressure in a private house. In order to install it, you will have to think about where exactly the tank can be placed. Some owners of private houses, instead of a hydraulic accumulator with a membrane, install ordinary large plastic tanks (volume 200 l).

In such cases, the pressure switch replaces the float sensor, due to which the tank is filled with water when necessary. Such a tank should be located as high as possible (attic, top floor). It is necessary to think about its most suitable configuration in a timely manner.

To save space, you should choose a narrow flat tank; its shape can be arbitrary. The installation should be carried out in such a way that access to it or to the hydraulic accumulator is maintained (alternatively, it can be made so that it can be easily removed if necessary). This is important, as otherwise difficulties will arise during maintenance, repair or replacement of the device.

A store-bought hydraulic accumulator does not require any preparation for installation, but you will have to create holes in the tank through which water will flow in and out. It would be a good idea to install an additional shut-off valve, with which you can quickly drain the water in the event of an accident. The pipes that take and supply liquid to the water supply system are mounted to one water pipe.

Nowadays, it is most convenient to use plastic pipes for assembling a water supply system: they are easy to install and, what is very important, they are reliable. It makes sense to install check valves on the pipes: they will prevent air from the pump and water from entering the container when the equipment is turned off.

Now you can begin assembling and installing a suction pump to increase pressure in a private house, which was probably purchased disassembled.

If you decide to mount the pump to the wall, then do not forget about the markings for fasteners. After the device is installed, it is connected to the water supply. This is not difficult, but it is important to carefully monitor the direction of water movement in the device (there should be special marks on the body).

The liquid in the pump to increase water in a private house must move from the tank to the water collection points. In other words, the installation must be connected according to the following scheme: hydraulic accumulator - pump - consumer. The next stage is piping the pump.

Below is a diagram of connecting a pump to increase water pressure in a private house to the water supply system.

Installation is usually carried out as follows: the pipes at the beginning of the system are disconnected and a pump is connected to them (fittings are used for this).

It is important that the connections are tight. If a pump is “screwed on” to increase water pressure in a private house, then the threaded connection must have a seal in required quantity(FUM tape, linen thread). To connect the device to plastic pipes fittings will be required.

It is important to check the operation of the system; to do this, fill the tank with the float with water. It is necessary to make sure that the container does not leak, and also check the operation of the sensor. In the absence of these problems, you can test the work yourself.

To do this, connect the device to the network (automatic mode), open the tap and observe its operation. If everything is correct, then the pump to increase water pressure in a private house should automatically turn on, and the liquid pressure should increase significantly.

Installing a circulation pump to increase water pressure

Installation is carried out in the same way circulation pumps increased pressure in a private home. They are cut into the water supply in a certain place. It is important to consider the direction of fluid movement. If the device is not positioned correctly, water will pass through the pump.

But you will not notice an increase in pressure, since the device will not perform its task. Therefore, carefully study the instructions; they describe in detail the correct position of the pump to increase water pressure in a private home. If the pump connected to the network affected the water pressure, then it means that no errors were made during installation.

Installation of a pump with a hydraulic accumulator

Installing a system equipped with a hydraulic accumulator is somewhat more difficult. Before proceeding with installation, you must carefully study the design pumping unit to increase pressure in a private home. The pump is connected to the hydraulic accumulator using special hoses. A pressure switch, which is also connected to it, is responsible for turning the device on and off.

The figure below shows in detail the principle of operation of a pump with a hydraulic accumulator and the sequence of its connection. The pump turns off after the tank is full.

It is quite difficult to configure the relay. Therefore, carefully read the instructions and recommendations of the manufacturer. If you have never done anything like this, we recommend that you consult with a specialist or entrust him with all the work.
