Additional pump in the water supply system of a private house. Which pump to choose to increase the water pressure in your apartment

Consumption ecology. Manor: The lack of sufficient water pressure in the system is, of course, not a disaster, but there is little pleasant in such a situation. If you wash dishes or take a shower somehow, then household appliances, such as a washing machine or dishwasher, may simply refuse to work. Luckily, water pressure pumps have been invented to solve these kinds of problems.

The lack of sufficient water pressure in the system is, of course, not a disaster, but there is little pleasant in such a situation. If you wash dishes or take a shower somehow, then household appliances, such as a washing machine or dishwasher, may simply refuse to work. Luckily, water pressure pumps have been invented to solve these kinds of problems.

How it works

problem low pressure in the water supply system is solved using two types of devices: circulation and self-priming pumps. The former are simpler and easier to install into the system. Ordinary circulation pump consists of a rotor, an impeller fixed to it and an engine that rotates it all. Usually, if there is water in the system, but its pressure is weak, one or two pumps are enough.

The task of increasing the pressure in the water supply system is solved in two ways: by installing a circulation or centrifugal self-priming pump

But if water does not flow to the upper floors at all, you will have to install a high-power pumping station with a hydraulic tank. Such a device is simply installed as part of a plumbing system in a suitable location. The impeller spins, giving the water flow additional acceleration.

As a result, the pipes fill with water faster, providing the necessary level of pressure in the water supply. These are compact devices. low power designed to solve local problems. Suction pumps are more high performance and more complex device.

In addition to a suction pump capable of pumping water to a considerable height, the system is also equipped with a hydraulic accumulator equipped with a special membrane. The operation of this technique is automated, a pressure switch is used. Water is first supplied to the storage tank, and then enters the water supply, providing the necessary characteristics within the system.

Thus, if centrifugal pump allows you to eliminate the problem in a separate area, then the suction equipment is used to regulate the entire water supply in a house or apartment. Self-priming booster pumps are capable of lifting liquid to a height of up to 12 m, while their power starts from 2 kW / h.

The booster pump works as follows. When the water flow reaches 1.5 cubic meters, the motion sensor petal changes position. It leads to automatic start pump. When the water flow stops, the pump turns off. This type of equipment is used both in private cottages and in apartment buildings.

It is especially relevant in high-rise residential buildings, where to ensure the normal delivery of water to the upper floors without a special pump through different reasons impossible. Installing a single pump or even a special station with increased power can be a real salvation for residents of the upper floors.

Sometimes you have to use not one booster pump, but two or more. Such a need is sometimes faced by owners of houses in which the plumbing system was originally designed with errors. In this case, you will have to calculate the cost of reworking the water supply (if such a possibility exists at all) and the cost of installing additional equipment.

A small pumping station installed in front of household appliances will ensure a normal supply of water

It should be remembered that in order to transfer hot water dedicated to specific types of technology. They are made of special heat-resistant materials, so they are more expensive than more simple models designed for contact only with cold water. There are also universal booster pumps that are suitable for both cold and hot water.

The power of a conventional circulation pump is small, it consumes less energy than some incandescent lamps. When it is included in the system, it is possible to achieve an increase in pressure by about 2-3 atmospheres. If more serious correction of characteristics is required, more powerful equipment should be preferred.

Circulation pumps tend to work "to a dead end", i.e. they do not need to be turned off even if all taps are closed and no water is taken from the system. Inlet pumps operate in approximately the same way to increase water pressure. These devices are similar in design to circulation models.

If such a pump is turned off, water will circulate freely through its housing. As soon as power is supplied to the motor, the pump turns on. The impeller begins to rotate and the water pressure in the system increases. When faced with a choice between automatic or manual systems, the former is usually preferred.

Comparison of the scheme of the plumbing system with and without a booster pump allows you to more accurately represent the installation procedure for such equipment

It is more convenient to use such equipment, and it lasts longer, because it does not work idle. It makes sense to take a manual pump only in cases where it will be used either for a very short time (temporary option) or extremely rarely (in summer, in the country, only on weekends).

The diagram clearly shows the device of a pump with a wet rotor. Water washes the moving parts of the pump and absorbs excess heat

The concept of dry and wet rotor refers to information about the cooling system of the device. In the first case, it is cooled by the air flow, and in the second - by the flow of pumped water. A wet rotor pump is cheaper, but has a shorter life due to the negative effects of sediment that accumulates on the working parts during pumping water. Models with a dry rotor cope with their tasks more efficiently, and their service life is longer.

Pump power and system requirements

The power of the device must be commensurate with the needs of the system. Lack of pressure is bad, but also too great pressure no need. If a too efficient pump is selected for the water supply, the pressure in the system will increase, and all its elements will be subjected to unnecessary additional load. This leads to rapid wear and frequent breakdowns.

The water pressure in the system must not be less than two atmospheres. This is enough for comfortable water procedures, as well as to start the automatic washing machine. Although some models are more demanding in terms of operating conditions. For example, if the house has a shower, hydromassage, jacuzzi or other similar devices, the pressure should be higher.

In this case, it is better to increase the pressure in the plumbing system to 5-6 atmospheres. Certain types of equipment require even higher performance. Therefore, the first step before installing a pump that increases pressure should be to study the documentation household appliances. If any devices are planned to be purchased in the future, their characteristics also need to be taken into account.

To create a permanent high pressure the system uses special pumping stations, including a pump and a hydraulic tank. Their work is controlled by a pressure switch.

Accurate calculations can be made by a specialist, but preliminary data made “by eye” are usually sufficient. To determine what pressure really exists in the system, you can use a regular liter jar. The water is opened and measured, how many liters of water poured out of the tap within a minute.

Then you need to deal with current needs. If the inconvenience is due to the fact that it is difficult to take a shower with an open tap in the kitchen due to low pressure, it is enough to use a conventional pump that will increase the pressure by a couple of atmospheres. But if the house has an automatic washing machine, shower cabin or other equipment of this kind, you should study the technical documentation.

Each such consumer requires a certain pressure of water. Lack of sufficient pressure can lead to costly equipment running idle. Household appliances, especially foreign-made ones, are not designed for such operating conditions. A failure caused by a lack of normal pressure can be considered as a case that does not comply with the warranty conditions.

You can focus on the maximum pressure in the plumbing system indicated in the device passports. In the presence of a large number of such equipment, it is worth contacting an engineer for advice. When choosing a model of a water pump suitable for increasing pressure, one should also take into account the needs of equipment, the purchase of which is planned in the future.

How to install a self-priming pump

Installing this type of pump is not difficult. This will require approximately the same skills and tools that are needed to install other types of pumping equipment. Schematically, the installation of a booster pump can be represented as the following steps:

• Choosing a location for the accumulator and pump.
• Installing a hydraulic accumulator.
• Installation of pipes for connecting equipment to the water supply.
• Hanging the pump on the wall.
• Tying the pump and accumulator.
• Checking the operation of equipment in automatic mode.

In fact, the pump and accumulator with a pressure switch is a variation pumping station. To implement the installation of such a system of devices, you first need to find a place to place the tank. Some craftsmen replace the accumulator with a membrane with a conventional large capacity, for example, a 200 liter plastic tank.

Instead of a pressure switch, the tank is equipped with a float sensor to ensure that it is automatically filled as needed. Such a tank is installed as high as possible: in the attic or on the top floor. Immediately you should think not only about the size, but also about the configuration of the container.

A flat and narrow tank will take less space than the traditional cylindrical model. Although there are no special requirements for the capacity configuration. When choosing a place for a container, access to the tank / accumulator or the possibility of easy dismantling of this element should be provided. This is necessary to complete Maintenance, repair or replace the device.

The photo shows the installation of check valves during installation plastic tank, as well as the procedure for connecting the inlet and outlet pipes to the water pipe

Hydraulic accumulators are supplied ready for installation, but the tank should be prepared. It has holes for water inlet and outlet. You can also make a separate shut-off valve to drain water into emergency. Branch pipes for supplying water to the tank and taking it into the water supply system are mounted to one water pipe.

IN modern conditions for the installation of a water supply system, it is more logical to use easy-to-install and reliable plastic pipes. To prevent air from being sucked into the tank from the pump, and also to prevent water from entering there when the equipment is turned off, both nozzles should be equipped with check valves. After that, pipes are mounted, with the help of which the tank is connected to the plumbing system.

Circulation pumps occupy a minimum of space, do not interfere with the maintenance of household appliances

After the tank or hydraulic accumulator is installed, and the laying of the necessary water pipes, you can start installing the suction pump. Usually such a device is delivered unassembled. It is first collected, and then proceed to installation.

If you decide to mount the pump on the wall, you should first make markings for fasteners. Then the pump is suspended and connected to the water supply pipes. In general, this is not a very difficult operation. Important point- the direction of the liquid in the pump. It is indicated on the case with special marks.

The pump should be installed in such a way that the movement of water is from the tank to the water points. Thus, the scheme for installing and connecting a pressure boosting pump is as follows: accumulator-pump-consumer. Then the pump is tied.

All connections must be carefully sealed. If a booster pump is connected threaded connections, you should use a suitable sealant: FUM tape, linen thread, etc. The amount of sealant should be sufficient, but not excessive. TO plastic pipes the device is connected by means of special fittings.

After that, you should check the operation of the entire system. If a tank with a float sensor was used, it is filled with water. Check not only the operation of the sensor. container that serves storage tank should be checked for leaks. If everything is in order, you can proceed to testing the operation of the pump itself.

The pump must be connected to electrical network. It is recommended that the pump switch lever be set to the automatic position. It remains to open the nearest water faucet and observe the operation of the device. If the installation is done correctly, the pump should automatically turn on, and the water pressure will increase noticeably.

Similarly, the installation of pressure boosting circulation pumps is carried out. For them choose appropriate place in the plumbing, and they cut it there. In this case, it is also extremely important to correctly connect the pump, taking into account the direction of fluid flow. If the position of the device is incorrect, the pump will still let the water flow through.

Scheme of connecting the circulation pump to the plumbing system. The installation of such a device is very simple, but it is important not to confuse the direction of water flow.

But his work will be extremely inefficient, since the device simply will not function. In the instructions and on the case it is indicated in detail correct position pump. After installation, the pump is turned on in the mains and its operation is checked. If the water pressure at the nearest water intake point has increased, then the installation is done correctly.

A small pressure booster pump is simply plugged into the system. Usually for this it is enough to remove a piece of pipe of the appropriate length at the beginning of the water pipe.

Installing a system with a hydraulic accumulator looks a little more complicated. First you need to deal with the device of the entire structure. The pump is connected to the accumulator using special hoses. Then a pressure switch is connected, with which the equipment will turn on and off.

This figure shows in detail the principle of operation of a pump with a hydraulic accumulator and how to connect it. The pump fills the tank and then turns off

The setting of such a relay deserves special attention. Before starting work, it is recommended to carefully study the instructions and recommendations of the manufacturer. If there is not enough knowledge and skills for high-quality installation and configuration of equipment, it is better to contact a specialist for advice or completely entrust him with all the work.

Not always a booster pump is needed to solve the problem with low water pressure in the system. To begin with, it does not hurt to diagnose the condition of the water pipes. Their cleaning or complete replacement can restore normal pressure without additional equipment.

To understand that the problem is in the poor condition of the water pipes, sometimes it is enough to ask neighbors who live in apartments on the same floor or higher. If they have normal pressure, you almost certainly need to clean the pipes. If the picture is the same for everyone, there may be more serious problems affecting the entire plumbing system of the house and even the area.

In high-rise buildings, water sometimes simply does not flow to the upper floors. This requires high-powered and rather expensive equipment. It makes sense to cooperate with other tenants to share the costs. It is a good idea to demand that the organization that receives the payment for the water supply solve the problem, since it is they who must ensure the supply of water to the consumer.

The lack of water on the upper floors is a violation of the requirements fire safety. When communicating with the water service provider, it is worth paying attention to this point and mention the possibility of litigation due to non-compliance with the law.

Installation of equipment in apartment building Best to get a professional plumber management company. He is with the system better familiar, and will be responsible in case of leaks or breakdowns caused by poor installation of equipment.

How to choose a pump to increase water pressure

When choosing water pressure pump, hot or cold, pay attention to the following specifications

• pump power - the more power, the more it consumes electricity.
• pressure indicator - each water supply system is not at the same level, pipes pass at different levels, so this indicator is very important.
• its performance is the volume of pumped water per minute.

Based on these parameters, you can easily choose a pump to increase the water pressure in the apartment or a similar pump for the house. The lineup pumps presented in our store, allows you to choose a device with exactly the technical characteristics that are suitable for your water supply system. Naturally, you need to know the parameters of your system - its volume, approximate water pressure, the maximum height between horizontal pipes.

Contemporary public utilities often does not provide the supply of water of the required parameters to the common highway. A pump to increase the water pressure in some cases would be useful. But the choice of device depends on many factors. Sometimes a complex solution can save the situation.

Technical parameters of water supply laid down in the regulations

Modern household appliances are designed for water supply with a pressure of 4 bar. If the pressure in the tubes is less, the devices turn off. You can check the pressure on the pressure gauge or using homemade device- a transparent tube 2 m long connected to a tap.

equivalent physical quantities pressures are recognized: 1 bar, 1at, 10 m of water. Art., 100 kPa. Such indicators can be found in the passports of the pumps.

The normal pressure is considered to be the pressure for which pipes, joints, gaskets are designed - 4 bar. At 6-7 bars, leaks appear in the line, at 10 the pipes can break. You need to know this when choosing a pump to increase water pressure.

Is it always possible to install booster pumps

In a private house, the lack of pressure in the line is stopped installed pumps. At the same time, their power supply through the battery tank allows you to have stable input parameters. Mount devices in areas where you need to increase the pressure after the pump. The pump for increasing the water pressure differs from the centrifugal one in that it turns on periodically, upon request. The centrifugal apparatus in the system is constantly running.

In an apartment building, there can be several problems:

• in the manifold on the distribution comb is not desired pressure for any reason;
• during peak loads, water flows to the upper floors intermittently;
• In the apartment at different points the pressure is different.

Examinations should show the reason for the lack of pressure. There are cases when the pressure in the line is normal, but the downstairs neighbor narrowed the conditional passage when replacing pipes. It happens that the pipes are completely clogged with rust. In such cases, it is useless to install a pump to increase the water pressure in an apartment with a common wiring. It is necessary to restore the conditional pass in the system.

A legitimate way out could be to install an accumulator tank in the basement, common to the riser, then all residents can use a pump that increases the pressure in the water supply on a common line.

With a general lack of water in the system, it is prohibited to install an additional pump to increase pressure, penalties are comparable to the cost of the equipment.

Pump Selection Criteria

First of all, a pump is selected based on the outlet pressure indicator, about 4 bar. It is important to know the dimensions, wet or dry rotor, noise. When choosing a high-pressure pump, the presence of automation or manual control can be decisive.

Used for hot and cold water supply different systems pumps. Cold water systems are equipped with pumps from well-known manufacturers:

1. WILO - the booster pump is recognized as the most purchased. Differ in simple device, reliability and long term guarantees.
2. – works silently, in demand, warranty is issued for 1 year
3. OASIS is a brand that strives to get into the TOP, and so far it succeeds due to simple device, reliability and low price.
4. Gileks is a recognized domestic leader in the production of pumps.

Their models are compact and quiet. Branch pipes for installation are unified for Russian water utility systems.

Pumps to increase water pressure are of two types, with a "wet" and "dry" rotor. Devices with a wet rotor are installed in a pipe. The power part is located outside the pipe, has air cooling, is attached to the wall as a cantilever - a pump with a dry rotor.

The high pressure water pumps on the manifolds run continuously. More often they are equipped with more than one, several wheels, the pressure increase occurs in steps. Such devices can create a pressure of several tens of atmospheres on the injection line. Industrial plants high-pressure models are only available with a free-standing air-cooled engine.

Installation of the pump in the apartment

First you need to carry out the distribution of water to devices that need a stable pressure. Installing the pump before wiring will make it possible to get by with one device, which is turned on manually or automatically.

Before starting work, make sure that the reinforcement does not let the agent through. To guarantee the common cold water riser must be blocked from the collector.

Steel pipes should be welded by a professional welder. Polypropylene conduits are connected with special fittings, a soldering iron is required. Be sure to install shut-off valves before and after the pump.

It is important to correctly position the high pressure water pump impeller in the direction of fluid flow, as indicated by the arrow. A common booster pump can be installed immediately after the root valve, then the pressure is maintained at all points of extraction. After checking the system for tight connections, the pump is plugged into the outlet.

Using the accumulator tank and high pressure pump

Such a scheme will be required if a multi-storey building chronically lacks pressure on the upper floors. Turning on the high pressure pump is due to an increase in the flow rate on the line to a certain value. Since pressure and flow are interdependent indicators, an increase in flow is a signal to turn on the high pressure pump.

Turning on, the pump will create the necessary pressure in the system on all floors. Thus, it is possible to solve the problem of water supply for residents in a cottage or multi-storey building.

booster pump cost

The market offers models of pumps for increasing water pressure at a price corresponding to the prestige of the brand, the degree of automation, and parameters. The minimum pump costs 2500 rubles. Brands that work on the principle: set it and forget it, can cost 30,000 rubles.

Industrial installations for highways are purchased by agreement. In any case, the installation of a high-pressure pump will require a survey of pipes and an installation project approved by the Housing Office.

Video about the operation of the booster pump in the water supply system

The water pressure booster pump is a very important part of the water supply system. They are mounted in individual and centralized systems, since the increase in pressure increases productivity. Also very often used in everyday life, because this problem can cause numerous problems with full functioning technical devices in the house, such as: washing machine, dishwasher, speakers, etc. In our article, we will discuss the features of its work, varieties and advantages.

To denote such a concept as pressure, two such quantities are used:

1. bars;
2. Atmospheres.

Important! The ratio of these two quantities is displayed in such a scheme: 1 bar \u003d 1.197 atmospheres \u003d 10.19.

There are norms for pressure in city water pipes, according to which it should be 4 atmospheres. Today, pressure drops can be frequent and high and can ruin your device, because 6-7 atmospheres have a devastating effect on the system. Especially in this situation, imported modern technology is sensitive. If the pressure, on the contrary, is low enough, then this may affect the operation of the washing and dishwasher.

Important! The lowest indicator for the work of elementary equipment should be at least 1.5 atmospheres, and for the work of firefighters - 3 atmospheres.

If you are going to buy a pump to control water pressure, then you need to decide on the problem. The most popular complaints about the operation of water supply systems are:

• Weak water pressure in the tap;
• Lack of water on the upper floors of the building.

The first problem can be solved by installing a pump, but for the second it will be useless. In such a situation, it is necessary to install a pumping station.

The concept of a pressure booster pump

Normalization of work autonomous system water supply takes a very long time. Although many people think that it is enough to make a well and install a pump in it, it is important to know that the water temperature is very low, so it has to be stored in a container, and because of this, the head pressure may drop. To get out of this situation, a flow mechanism was invented to increase pressure.

Their direct purpose is to fully optimize the pressure level in the water supply system in a house or apartment. They have the highest demand on individual plots. Sometimes these pumps are installed to maintain technical requirements appliances.

Design features

Design features are manifested in the hardware complex, which consists of several units - an electric motor and a pump. Features of the scope of application require the use optimal materials, such as:

• Ceramics;
• Brass;
• Steel that does not rust;
• Cast iron.

Attention! It should be noted that all of the above materials combine common feature is corrosion resistance.

The pump housing is almost completely immersed in water, therefore it has two sockets in its structure:

• Front type for suction;
• Radial feed type.

It is also worth noting that a wet-type rotor is installed here, which accompanies a decrease in the temperature of the installation elements. This part gives the device two such advantages:

• Almost silent operation;
• Extending the life of the device.

Attention! To date, there are equipment with vane coolers, which are much more efficient, but also have more noise during operation.

Advantages of the pressure booster

This type of device has a large number of pluses in their performance, which reflect the ease and comfort of their operation:

• They have the ability to increase and maintain the stability of the pressure level;
• small parameters;
• Optimum noise level;
• High resistance to corrosion;
• Installation variations on the pipeline;
• Ease of installation and removal of the structure;
• Automatic work;
• Low energy consumption;
• Ability to work with different temperature conditions of the liquid.

Areas and effectiveness of application

The following factors can influence the pressure drop:

• Filter clogging;
• Overgrowth of pipes;
• Plenty of water intake, etc.

For multi-apartment buildings, such situations are easily resolved, but for individual systems, a pressure booster will be the most optimal solution to the issue.

If the pump works in conjunction with the drive, then they can easily cope with water intake problems. Such a scheme has a huge number of advantages in operation, especially for a surface or submersible apparatus.

When installing a booster pump, not everyone produces correct calculations its performance, which is very important detail. Indeed, if the indicators of the device and the line do not match, then the effect may not appear. First of all, this is due to the fact that the installation of the device does not increase the pressure of the line, because it combines several points of water intake. The final result will be a decrease in fluid supply.

Attention! If your neighbors already have such a pump, then they reduce the level of your flow of cold and hot water. It is necessary to pay attention to this. Indeed, in this situation, the pressure booster starts to work as much as possible, which reduces its life cycle.

For best result efficiency of the device, it is necessary to mount it together with a special tank.

In the event that the room does not have the parameters for placing this installation, then you can install submersible pump which is placed in a container. Its main advantage is its compact size and silent system performance. In addition, it has a membrane storage area, which can be included in the central or main system.

It is also worth highlighting the disadvantages of functionality - this is a more complex installation. In addition to connecting to the highway, you also need to configure the automation of work.

Advice. To avoid mistakes, you need to use standard connection mechanisms or use the services of professionals. But, do not forget that if your pump fails due to improper installation, then the warranty ceases to apply and you will have to carry out repairs at your own expense.

Types of models

The problem of unstable pressure covers a large number of areas of human activity, so the market segment contains a large number of models for different purposes and a distinctive volume. As for the size, there are devices that are compact for domestic installation and overall for industrial areas.

Now we will get acquainted with these types in more detail.

Household pumps

These types have a number of such advantages:

1. Compact, handy size;
2. Low energy costs;
3. Low price;
4. Ease of operation.

Attention! Household devices function optimally in the temperature range from -15 to +100 degrees.

• steel;
• cast iron;
• metal-plastic;
• Polypropylene.

Pumps are also divided according to such a criterion as the type of control:

1. manual;
2. Automatic.

Manual pumps

What is this mechanism? This is the connection and shutdown of the system on its own, which provides some inconvenience for operation.

It is also worth highlighting the advantages of this type of equipment:

• Very high resistance to overheating of the device;
• Small cost;
• Durability. Very rarely there are system failures.

With automatic control

pump with automatic control starts working as soon as the fence opens, and its volume instantly collects data on the flow sensor. When closed, the faucet automatically shuts off. This mode prevents dry operation of the device, which increases its life cycle. It is worth highlighting the disadvantage of the system - this is its high price.

But this is not a huge minus for the performance of the device, as it has a huge number of significant advantages:

• Convenient operation of the device;
• Small installation dimensions:
• Low noise level during operation, which almost does not stand out from the general background;
• They have a hydraulic accumulator that can operate at zero pressure;
• High engine power.

Other types of pressure control pumps

There is also a classification according to such a criterion as the method of cooling the body, which can occur during the operation of the impeller or pumped water. There are such types:

• Cooling occurs during the operation of the blades, which are mounted on the shaft. The design is called a dry rotor. Characteristic features for them are: high efficiency, low noise level.
• Liquid cooling, or the so-called wet rotor. Signs of difference of this type is the silent operation of the device.

Attention! There are also universal models that are suitable for working with any water temperature.

The most famous brands of pumps

To date, there are a number of leaders in the production of water system pressure boosters. All of them have a common structure scheme, but are made of various materials. Let's take a look at them:

• WILO is a manufacturer of high quality pumps, reliable, easy to operate and with a long-term guarantee;
• Cl15grs 15 is a pressure booster pump, which is characterized by the presence of a flow sensor, which is included in the power supply circuit;
• Grundfos - the second in terms of demand in the country, differs from WILO in its lower price and silent operation;
• OASIS pumps - their biggest plus, which distinguishes them from other manufacturers - is the ease of installation and dismantling, the durability of the device;
• Aquaphor is a pressure booster that is characterized by ease of installation and high reliability.

Choosing the best pump

• Power and performance indicators;
• Noise level during operation;
• Authority and accreditation of the manufacturer;
• The maximum number of pressure that the device can produce.

Individual characteristics of models that you should pay attention to when buying a pump:

• Dimensions . It is worth choosing the dimensions that are suitable for installation in the place you have planned.
• Temperature range. This indicator depends on the nuances of your plumbing system.
• Connection options. For each pipe, you need to select the appropriate modification.

When choosing a pump, you must know the system pressure and performance. You can find out these values ​​\u200b\u200bin your own or hire a specialist. We will give you a small diagram so that you understand the deduction system. If the pressure in the system is 1.5 atmospheres, then a compact device that can be installed in the pipeline is also suitable for its maintenance.

Advice! Purchase pumps from licensed retailers.

We connect to a common highway

If your house consists of a highway system, then this must be taken into account when installing the pump. It’s just that not only you, but also all neighbors can have such equipment - this will lead to the fact that the mechanism will work at full strength, and the pressure will not increase. In addition, this situation can lead to a breakdown.

Advice! To avoid this situation, you need to install a storage tank in which reserve water will be stored. This liquid is very useful when reducing pressure.

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 pump for water, including a household one for an apartment, turns on automatically when it is fixed critically. low level pressure. 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 both cold water and hot water. 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.
