Pump for water pressure. Pumps for increasing water pressure. Where to install a booster pump in the plumbing system

Main difference circulation pump from booster (supercharger) - function. Ensuring the movement of fluid through the water supply / heating system and creating increased pressure in certain areas are different tasks. These tasks are solved by different equipment. We deal with the principle of operation of devices and identify how exactly the circulation pump differs from the booster.

booster pumps

The task of the booster (pressure) pump is to increase pressure in a certain area. This is a narrow-profile equipment, which is why manufacturers cannot boast of a huge number of models. However, the range is sufficient, and there are even leaders:

• AC159-160A AQUARIO,
• PB WILO,
• UPA 15-90 GRUNDFOS.

The greatest demand is for equipment that can raise the pressure from 0.2 to 1 atm (that is, at least 0.8 atm). To raise up to 3.5 atm, booster stations are used that are larger than the pump and have a slightly different configuration (the storage tank is often included).

Principle of operation

The impeller, mounted on the shaft opposite the suction pipe located in the lower part of the body, sets the water in a radial movement (with a minimum of hydraulic losses) in the direction from the center. In the process of this movement, through the work of the internal radial blades of the impeller, the mechanical energy is converted into kinetic energy. The flow rate increases. At the outlet of the impeller, a spiral is installed that directs water into the diffuser. In it, part of the kinetic energy is converted into pressure, that is, the energy of pressure.

Inkjet devices

A special feature is the suction effect created by the ejector installed in the housing and connected to the suction chamber. One part of the pumped water passes to the discharge pipe, the second part is recirculated. Recirculation provides a vacuum in the suction chamber. Jet centrifugal devices are produced in two configurations: one-piece and with a separate unit, where the ejector and suction chamber are located. These models are used in the organization autonomous water supply from external source(well).

Vortex devices

Feature - the presence of many radial blades on the periphery of the impeller. The vanes transfer mechanical energy to the water while recirculating it radially between the vanes themselves and the double channels located on either side of the impeller. Each blade takes part in the transfer of energy - the pressure builds up gradually. Result: smooth and strong flow, high outlet pressure.

Circulation pumps

The task of the equipment is to ensure the continuous movement of water. Circulation pumps are used in heating systems and hot water systems (including underfloor heating). The device sets the water in motion, but the pressure in the system does not change. Devices are divided according to the type of rotor into wet and dry.

"Dry" circulation pumps

In "dry" type devices, the rotor does not come into direct contact with the liquid. Working surface rotor and motor are separated from each other by sealing rings (stainless steel). The water film located between these rings during the operation of the device seals the connection due to the difference in pressure (external and system). The rings are self-adjusting (adjustment is ensured by a clamping spring).

One of the advantages of "dry" pumps is high efficiency (up to 80%), the disadvantage is the equally high noise background created by the cooling fan.

"Wet" circulation pumps

In "wet" type devices, the rotor contacts the liquid directly. It consists of a housing (materials: aluminum, bronze, stainless steel, cast iron) with a ceramic or steel motor located inside and an impeller fixed on the shaft. The stator and rotor are separated by a special glass, which provides insulation for live elements. All parts of the device work in the pumped medium (except isolated ones).

Water plays the role of a coolant and lubricant. There is no fan, which reduces the noise background to zero, but at the same time the efficiency drops significantly - up to 55%.

"Wet" pumps are used in individual systems, dry - in industrial and others that require power, not silence.

What is the difference between a circulation pump and a booster pump

circulation and booster pump are fundamentally different. They have different tasks, different solutions to these problems: circulation - a device that ensures the movement of the coolant in the system, pressure - a pump that increases pressure in certain sections of it.

The circulation pump sets the liquid in motion by sucking it in on one side and ejecting it on the other due to centrifugal force. The same principle is the basis of work drainage pumps. The pressure remains static.

Circulation pump

The booster pump has an effect specifically on the pressure - it increases it.

Boost

Let's look at an example:

• water enters the plots along the highway from the water tower;
• in the line pressure 1 atm;
• during the period of active water consumption, the pressure drops to 0.2 atm, which is not enough to supply water to the second floors;
• a booster pump is connected to the line, and while maintaining active water consumption, the pressure in the system is kept at 2 atm.

Prior to connecting the booster pump, the system successfully functioned with the circulation pump, but could not cope with increased water consumption.

As for the choice of which pump to install - circulation or booster, the question is incorrect: the system may well include both devices - it depends on its complexity. Circulation will ensure the movement of the coolant, booster - pressure in the right areas, for example, at a gas boiler. The system can function successfully without a booster (relatively simple ones do not need them, which is why the device is considered narrow-profile), but not with it alone: ​​the device increases pressure, and does not ensure the movement of the coolant. That is, "vs" does not work here.

When calculations are made by specialists, such a question does not even arise: you need pressure pump- it is included in the system, it is not needed - it is not included. Given the importance of the location of the device in the system, we recommend contacting the masters, and not trying to assemble it yourself.

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- washing machine or dishwasher, boiler, gas hot water 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.

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, the 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.

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.

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;
• pumping stations self-priming type.

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 an external source of recharge. 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.

Main characteristics

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.

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 a relatively low power, they increase the pressure level by 1.5-2 atmospheres, are made from high-quality durable materials (cast iron and of stainless steel) and produce virtually no 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.

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.

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 the dishes or take a shower as little as possible, 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, they solve using two types of devices: circulation and self-priming pumps. The former are simpler and easier to install into the system. A conventional circulation pump consists of a rotor, an impeller mounted on 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 pressure boosting pump should be to study the documentation of 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 such a technique should be consulted with an engineer. 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, a pump and a hydraulic accumulator with a pressure switch is a variation of a 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. Good idea- demand a solution to the problem from the organization that receives payment for water supply, since it is it that 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.

Perhaps the main parameter in modern 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, then they automatically affect its performance.

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

1 Features and purpose

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

Through the pipeline, water flows to the taps, which can then be obtained in any place suitable for this. 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 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.

Pressurized showers and a variety of whirlpool baths require even more serious conditions. They can already be operated normally if the water pressure in the water supply system is at least 4 atmospheres. Various devices for hydromassage are not limited to the declared characteristics.

As you can see, serious requirements are imposed on the conditions in a modern water supply system. And they don't always answer them. So, in an average apartment, the water pressure in the water supply system can be only 2.5-3 atmospheres. Good pressure also happens, but here it 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 deal with the creation of local water supply systems 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 erroneously or in violation of certain standards.

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

2 Types and characteristics

As you can see, pressure boosting pumps have different designs and in this parameter they are very seriously different from each other. To begin with, consider their main division according to the type of design and purpose. According to these parameters, they are divided into:

• increase in pressure level;
• Self-priming booster pump stations for water supply systems.

The first variety is a standard booster pump. It is called circulation because of its contribution to the circulation of fluid in the pipes. The device has, as a rule, small dimensions and is very compact. It is cut into a certain section of the pipeline, which increases the pressure level and the fluid circulation rate on it.

Initially, these pumps were conceived for arranging hot water and heating systems. This is due to the significant length heating circuits, as well as their resistance at nodal junctions.

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 already used not so much for pumping hot liquid, but for stimulating the general level of water movement.

The circulator consists of a small motor that rotates the rotor part with an impeller. It is this small mechanism that is able to pump water into the chamber and significantly improve the performance of the entire pipeline.

The most popular pressure booster pumps are manufactured 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 recharge.

2.1 How to choose booster pumps?

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

IN last resort, measure the pressure yourself. This will help you select the optimum capacity water pumps. After all, there is no point in overpaying for too powerful equipment, which in your case simply cannot reach its potential.

A circulation sample to increase pressure is worth buying if you have water in you, but its pressure is too weak. Moreover, to level the lack of 2-3 atmospheres, one sample is enough. In some cases, it is necessary to install two pumps. But this happens quite rarely.

Pump booster stations should be chosen if you don’t have tap water at all, but lower in level in the system (for example, from neighbors below, if you are a tenant apartment building) it exists.

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

Of the popular manufacturers, it is better to buy pumps or Grundfos. Since the Wilo companies have established themselves on the market with better side and tested by time.

2.2 Features and connection technology

Pumps for increasing the pressure in the water supply are mounted quite easily. As a rule, they are embedded at the entrance to the system so that the stimulation of fluid movement takes place as conveniently and efficiently as possible.

So, 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 supply 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.
