Residents ordinary apartment multi-storey building may encounter a rather unpleasant situation: due to low pressure With running water it is impossible to take a quality shower, wash dishes or do laundry. Checking the pipes shows that they are in in perfect order and are not clogged with garbage, and the neighbors do not suffer at all from this problem, which confirms that insufficient pressure is present in only one room. The solution to this problem is to install a pump that will increase the pressure.
Peculiarities
Typically, a pump to increase water pressure is used in cases where water pipes relatively new, they are not clogged with anything, as well as the filter with aerators, and the liquid still flows slowly. This is usually explained by the fact that water initially enters the water supply system from the central riser under low pressure. In most cases, purchasing a pump completely solves this problem, bringing the pressure to normal.
According to European standards, the pressure in the pipeline should be approximately 4-5 bars or atmospheres, which is explained by the requirements for plumbing fixtures. For example, if the pressure corresponds to 2 atmospheres, then the washing machine may simply not start. If we talk about Jacuzzis or showers with special functions, then the situation becomes even stricter - an indicator of 4 bars will be the minimum acceptable for them.
Therefore, insufficient pressure can really lead to big problems.
Specifications
Raising and constantly maintaining pressure in the system is carried out using two types of pumps: circulation or self-priming. The first design is arranged as follows: there is a rotor, an impeller is attached to it, and there is also a motor that rotates the entire system. A circulation pump is called because it promotes the circulation of liquid in the pipes. Suction pumps offer higher performance and more complex device. They are equipped with a hydraulic accumulator with a special membrane. Water is first supplied to the storage tank and then enters the water supply. We can conclude that a circulation pump that raises pressure can solve the problem only in a separate area, while a suction pump can regulate the water supply in the entire apartment or even a house.
circulating
self-priming
Pumps that increase pressure in the water supply system are also divided into two large groups: with a so-called “dry” rotor and a “wet” rotor. “Wet” models are much more compact than “dry” ones. They do not make noise during operation and do not require special maintenance due to the fact that the parts are lubricated by themselves, by pumping liquid. Such a booster pump simply fits into the pipe and functions like a regular flow pump. Installation takes place in front of the water point or in front of household appliances, for example, a washing machine that requires water under a certain pressure.
These models are cooled due to the fact that water is pumped.
Among the disadvantages of a booster pump of this type highlight the fact that it is not characterized by high productivity and does not demonstrate a high pressure increase coefficient. In addition, the “wet” unit can only be installed in one position: the rotor axis electric drive can only be placed in a horizontal plane.
The second type are models with a “dry rotor”. They have better power and performance when compared with “wet” models. Such a pressure-increasing unit can be used simultaneously for several water intake points. Its power unit is equipped with an individual air cooling system and is located slightly to the side of the main body. As a result, the “dry” pump can only be attached to the wall surface as a cantilever. The internal parts of these models are periodically subject to friction, so it is necessary to ensure constant lubrication. It is also worth keeping in mind that it creates a significant amount of noise.
The device is cooled using blades located on the shaft.
In general, the water pump should only be started when the fluid pressure decreases. Control systems that offer both manual and automatic modes help ensure this. In the first case, the owner himself turns on the pump if he sees that there is a need to increase the pressure. Of course, he must control its use and avoid situations where the pump runs dry, without water.
In an automatic situation, the water flow sensor is responsible for the operation of the device. It turns on when liquid appears in the pipeline and turns off when it is empty. Thus, the pump is protected from running dry and, accordingly, from overheating and damage. Most often, the design is sold equipped with a sensor, but otherwise it can be purchased additionally.
When a part is purchased separately, it is installed after the pump itself.
If installation is carried out in household system water supply - that is, in a situation where the liquid pressure can be either normal or reduced, it is recommended to give preference to an automatic pump with a water pressure sensor. The device will turn on when the pressure is below normal, and turn off when everything is in order. When problems arise in large apartments or a house, you can purchase an entire pumping station. In addition to the pump, the kit includes a membrane-type hydraulic accumulator and a pressure sensor. They will not have to increase the water pressure, since they will create it themselves.
For hot and cold water supply use different systems pumps To interact with hot water structures are created from special materials that are heat resistant. Due to this, their price is much higher than for models in contact only with cold water.
There are also universal models, working in both cases.
The water pump, which is responsible for increased pressure in the system, also has the following technical characteristics: maximum flow, the amount of flow at which the equipment turns on automatically (ranges from 0.12 to 0.3 liters per minute), maximum and rated power, temperature of the working medium and dimensions of a suitable pipeline.
It is worth mentioning separately about automatic fire-fighting devices that increase pressure, because these pumps are used not only in everyday life, but also in industry. They are large backup units and are used in various water supply systems, as well as in fire extinguishing, irrigation and water cooling systems.
Their design is based on vertical and horizontal pumps, but the final design depends on the customer’s requirements.
Scope of application
As a rule, in a private house you can independently adjust the water pressure in the pipeline, but in an ordinary city apartment there are no such opportunities. The hardest thing is for the inhabitants of the upper floors. It is possible that the old pipes are completely overgrown with rust or limescale. A drop in pressure can also be caused by filters that have not been changed or cleaned for a long time. In addition, there is also human factor– utility services do not perform their duties efficiently, a neighbor narrowed the diameter of the pipe for one reason or another, and sometimes the required power of centralized equipment was initially incorrectly calculated. In such cases, all sorts of everyday problems begin to arise: you can take a shower only if the neighbors have gone to work, a malfunction occurs washing machine, turn off gas boilers And electric boilers. There are also situations when the pressure level in the water supply not only drops, but there is simply no pressure, and 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.
You can also find pumps that increase pressure among car wash owners, although in this case they differ from pipeline pumps.
The body is made of plastic, metal or high-quality alloy. Due to the movement of the pistons in the piston chambers, high pressure is created inside the system. Such designs also have a control system that prevents dry running. When the release valve in the gun is closed, the automation turns off the electric motor. This happens at the moment when the pressure inside the pump rises to operating pressure.
Manufacturers Undoubtedly, the best manufacturers
pumps that increase pressure are considered to be European companies. However, domestic companies also demonstrate decent results, especially in collaboration with Chinese ones. The German unit "Wilo PB-201EA" is considered the best water pump produced in this country.
It provides both manual and automatic control, has a capacity of 3.3 cubic meters per hour and a head of 15 meters. In addition, it functions smoothly in hot water and can withstand temperatures up to +80 degrees.
The Russian-Chinese booster pump “Jemix W15GR-15A” occupies a leading position in the “dry rotor” category.
It is inexpensive, reliable and can be used in both hot and cold water.
Wilo PB-201EA
The Danish device “Grundfos UPA 15-90 (N)” is equipped with a stainless steel housing and an asynchronous motor. It can operate either manually or automatically. The pressure corresponds to 8 meters, and the flow is 1.5 cubic meters per hour. It is very economical, because the power consumption reaches only 0.12 kilowatts. In addition, it does not make much noise, is very durable and has protection against overheating and dry running.
"Comfort X15GR-15" is one of the best budget water pumps. It is manufactured in Russian-Chinese production and has the following parameters: productivity - 1.8 cubic meters per hour, pressure - 15 meters. The device operates in both manual and automatic modes and is mounted horizontally with additional fixation to the wall. The maximum possible water temperature reaches 100 degrees, which means that it can be used in both hot and cold water supplies.
The pump consumes little energy, is not subject to corrosion and is inexpensive.

Comfort X15GR-15
Among the pumping stations, the Danish booster station “Grundfos MQ3-35” with automatic control. The suction depth reaches 8 meters, the pressure is 34 meters, and the flow rate is 3.9 cubic meters per hour. The station is equipped with a self-priming pump, electric motor and hydraulic accumulator.
It is reliable and has an anti-cycling function.
How to choose?
The more carefully the buyer approaches the pump selection process, the better effect he will receive as a result.
When purchasing a device, you need to take into account the following parameters:
- Device power. Knowing this indicator, you can determine how many water intake points the pump can serve. The required power depends on which cranes, which Appliances and how much pressure increase is required.
- Noise level. It is also recommended to find out this parameter in advance.
- Installation requirements. Some models can only function when paired with pipes of a certain diameter. Otherwise, the pump will not only not cope with the increase in water, but will also quickly fail if operated under overload.
- The height of water level rise created by the pump. This indicator is relevant in the case of pumping stations serving several apartments at once.
- The performance of the device or the amount of liquid that the pump is capable of pumping in order to create the required pressure within certain time. Please note that the value this indicator should be higher than the average water flow at the water intake point where the pump will be installed.
- Maximum permissible water temperature. Depending on this indicator, it is determined whether the pump will be installed for cold or hot water supply.
- Device dimensions. You need to know them in order to determine on which section of the water supply the pump will be installed.
- Manufacturer. It is recommended to give preference well-known companies, with due authority and numerous positive reviews.
In this case, you can count on guarantees, maintenance, and repairs.
First of all, a pump is selected based on the outlet pressure, which should reach 4 bars. When choosing a high-pressure pump, the determining factor may be the presence of automation or manual control.
Connection diagram
The connection diagram for the device that increases pressure is simple. The pump must be installed in front of the water intake points. Thus, as soon as it senses slight movement of water, the flow sensor will react and the pump will turn on. To create a system that will provide stable pressure to all the devices in need, you will also first have to consider the water distribution. Installing a pump at the right point will allow you to limit yourself to one device serving all water intakes.
If in a private house the necessary pressure is not available in the rooms on the upper floors, then you should think about using a hydraulic storage membrane tank of the maximum possible volume and a high-pressure pump. An increase in flow rate will lead to the activation of the pump, which, in turn, will service the system on all floors. This pumping station operates automatically. Its main element is centrifugal pump self-priming type. Even if the pressure in the pipes is at zero, it will lift water from the required depth, for example, from a basement sewer, and create the required pressure. The pressure switch will be responsible for turning on the electric motor only in a situation where the pressure is below the required level. The storage tank will create a certain supply of water. It will also be under pressure and will be wasted if the water supply in the main is interrupted. Following this scheme, the pumping station will raise the water to the top and provide the necessary pressure.
IN multi-storey building It is recommended to create a similar system, but with greater capacity, with a huge reservoir and with funds collected from residents for the entire riser. The basement contains a pressurized water supply, required amount which every resident will receive.
How to install?
It is very easy to install a pump to increase pressure with your own hands - installation is no different from inserting other devices into a pipeline. The first step is to shut off the water supply. If there are common valves that are located outside the apartment, then you should take care that they do not accidentally open. In the selected area, the pipe is cut and a pump is inserted into the freed space, which has two taps: at the inlet and at the outlet. If necessary, they will allow you to replace or repair the device. During installation, it is also important to consider which direction the water usually moves.
External threads are also created at both ends of the pipe, while adapters have internal threads. The adapters are also equipped with fittings.
Then, depending on the material from which the pipes and the booster itself are made, joining technologies are used. For example, to work with polymer pipes you will need a soldering iron. Then the integrity is checked, and control procedures are carried out under pressure and the motor is connected to the power supply. To do this, a three-core cable is installed connecting the pump to electrical panel. If possible, it is better to organize an additional outlet near the installation site and connect the device through a separate device protective shutdown. After the final check in operating mode, you can complete the procedure.
As a rule, the installation of the pump is carried out according to the instructions that were originally attached to it.
If a particular model can only be mounted in a certain position, this condition will be indicated.
The purchase and installation of a booster pump for the water supply system will ensure stabilization of the water pressure in the system. Old underwater pipelines (tie-ins) lose their throughput, cease to provide acceptable water pressure residential buildings.
This makes it impossible to use several points of consumption at the same time. Installation of the device will ensure the functioning of household water appliances, creating conditions for acceptable living.
Application
A booster pump is used when it is necessary to increase the pressure in an existing water supply connected to the central water supply. It creates sufficient pressure in front of the water collection points.
Such devices are also used for industrial purposes in the form of large backup installations that work to mitigate situations associated with accidents.
The main parameter of the water supply system is the degree of water pressure in the system. Acceptable pressure in the pipe will allow the entire water supply system to operate. European standards its value is prescribed to be 4-4.5 atmospheres. Less pressure will not ensure the operation of the washing machine and dishwasher, shower hydromassage cabin, jacuzzi, geyser.
For stable water pressure, designs operating in two modes are used:
- manual mode, which involves the operation of a constantly switched on pump;
- automatic mode, which ensures the operation of the pump using a water flow sensor. Such products are preferable. They are protected in the absence of water mode.
Water pumps are installed in apartments, private houses, country houses, cottages. The main condition for their reliable and proper operation – skillful connection electrical and water systems according to the attached instructions.

Old apartment buildings require pipe replacement. It would be the best option to increase pressure in apartments. But this process is long, labor-intensive, and therefore unpromising. Some residents solve the problem with water pressure by installing pipes of a smaller diameter, but this measure is expensive and not always effective. Installing a booster pump with a storage tank in the water supply system eliminates the problem.
There is a wide range of different devices available, according to design features water supply in apartments. The industry produces products installed on a hot water riser. Such designs allow you to change the pressure in the pump using adjusting screws.
Some types of devices increase pressure when the tap is opened directly hot water. They are applicable when using household devices: showers and water heaters.
This material will tell you in detail. and install .
If there is insufficient water pressure in the house, minimal diagnostics, including checking the serviceability of shut-off valves (taps, valves), the permeability of risers, and the presence of household contamination of pipes. Having confirmed that there is insufficient pressure in neighboring apartments, it becomes necessary to purchase pumping station for the whole house.
A pumping station is a type of water booster pump that has a hydraulic tank or accumulator. They are installed between the water supply and the water source, generating pressure in the water supply system. If one is installed in the house, but the water pressure in the apartments is not sufficient, it is replaced with a more powerful one. Sometimes it is enough to replace the accumulator or pump, or adjust the pressure using a pressure switch that monitors the operation of the accumulator and pump.
Principle of operation
The principle of operation of any booster pump for water supply is that the equipment system increases the pressure in the water supply network depending on the pressure available in the water circuit.
Advantage individual system heating in a private house or apartment lies in the short distance of passage of the coolant from the heating source to the battery. Forced circulation assumes the presence of a pump pumping water through heating elements: batteries, registers, pipes.
The pump is installed on a pipe reverse feed water, first drain the coolant or turn off the existing taps on the pipeline. Correct installation The pump will be indicated by an arrow, the direction of which coincides with the direction of movement of the coolant. After installing the filter rough cleaning and the pump itself, the system is filled with water, removing air by opening the central screw. The unit is connected to the network using a regular electrical plug.
The booster pump is installed strictly in horizontal position. It will not only contribute to his quiet operation, but will also prevent damage to the rotor.
Pay attention to the installation of the pump terminal box, preventing water or condensation from entering it. It is strictly prohibited to operate the unit in the absence of coolant in the system. The pump, equipped with a thermostat, is installed away from water heaters that can affect the operation of the thermostat.
At large sizes indoor water consumption increases significantly. Installing one pump may not fully provide the required pressure. In such cases, several pieces of equipment are installed.
How to choose a booster pump?
When choosing a product, we evaluate the condition of the plumbing system. The choice of unit of the required power depends on this.
When choosing and purchasing a booster pump, you need to take into account its main characteristics:
- performance;
- power;
- performance;
- size;
- guarantee period;
- price.
The units differ in technical characteristics and method of cooling the engine and housing. Products with “wet” and “dry” rotors are purchased.
The cooling process of devices of the first type is carried out by the liquid itself. They are silent in operation, but are demanding on the quality of pumped water, requiring constant and timely maintenance.
The motor housing of units with a dry rotor is cooled using an impeller. They are practical and reliable, although a little noisy. This type of pumps uses in great demand at the time of buying.
Some booster pumps are made with a fixed pressure rise value, other models may have several operating modes, are made with several sensors, control units, and have the ability to connect to a control panel.
Pressure boosting stations are purchased when there is no water in the taps. The presence of good water pressure from the neighbors below indicates that it is not reaching your riser.

You can find out how installation is done by watching the video:
Installing a pump that increases the pressure in the water supply ensures uninterrupted operation of all gas and water appliances and provides the opportunity to use water in bathrooms, Jacuzzis, and showers at any time of the day. The downside is the problem of space in the apartment when installing a hydraulic accumulator. You need to remember this nuance when installing a tank of 200-300 liters.
Plumbing - part utility networks private house and apartment. Due to low pressure in the pipes, residents often receive insufficient water. This situation limits the possibility of using two plumbing points at the same time, and the washing machine and dishwasher simply do not turn on. The only way to change the situation is a pumping station designed to increase water pressure. The power and productivity of the installation is selected individually. The compact device is able to normalize blood pressure and maintain an optimal level.
For the city water supply network, the accepted GOST standards assume a pressure of 4 atmospheres. This indicator is rare, seasonal changes water consumption causes it to fluctuate in the range of 2.5-7 atmospheres. Normal work a shower, washing machine and sink will provide the atmosphere parameter 2, a jacuzzi or watering a garden will require raising it to 4. In reality, the pressure is often 1-1.5 atmospheres, excluding stable work plumbing equipment. High pressure is also a negative factor, it negatively affects network elements, leading to their rapid wear.
Residents of apartments in upper floors and owners of private houses in summer period. First of all, it is necessary to exclude the possibility of pipes becoming clogged or overgrown. lime deposits. If the problem is not in the diameter of the pipes, then installing pumping equipment will radically solve the problem. The pumping station will raise and stabilize the pressure in the system.
Classification of pumping equipment
A budget-friendly way to increase pressure in the water supply of an apartment or private house - installation injection pump. Devices can be divided into main groups:
- manual - after being plugged into the power supply, they are constantly in working condition. 24/7 operation leads to rapid wear and tear. If there is no water in the system, the device may burn out;
- automatic - the design includes a sensor that turns on the unit when the liquid moves. This option will cost more, but will last longer. The equipment is designed to pump clean water, so it is better to equip the system with a coarse filter. The light weight and dimensions of the pump allow it to be installed directly on the pipeline.
Cooling of the pump motor is carried out in two ways:
- flow of passing liquid;
- fan mounted on the motor shaft.
Water pressure increasing stations are produced on the basis of water-lifting pumps.
If there is often no liquid in the pipes, it will be necessary to modernize the system and install a self-priming mini pumping station. This compact device is able to increase the pressure and maintain it at a given level.
The equipment design includes:
- membrane-type storage tank (hydraulic accumulator);
- centrifugal pump;
- system control relay.
The system automatically supplies water to fill the tank. The consumer uses the fluid accumulated by the accumulator. The main advantage of such a system is the prevention of pressure surges in pipes. In addition, the mini station provides a supply of fluid in the hydraulic accumulator, which can be used at any time.
As the water level drops, the pressure in the system decreases; at a given value, the relay turns on the pump again. The number of starts and service life of the pump depends on the volume of the tank; the larger it is, the less frequently the electronics operate, bringing the unit into working condition. The area of the apartment is limited, so it is problematic to find a place for a large tank; in addition, the absorption of water by the equipment leads to airing of the system. Installing a pressure booster station without permission from utilities is illegal, and getting approval will not be easy, so installing a booster pump is preferable.
How to choose the right unit
Among the main criteria for choosing a mini station to increase pressure in the system:
- Productivity – the amount of water that the installation pumps per unit of time (minute, hour).
- Power – selected based on the number of consumers. A high score is not always a plus. The station sucks water from a source (well, pipeline); if the pump operates faster than it is filled, the unit may be left without liquid and overheat.
- Correspondence of the model to the cross-section of pipes in an apartment or private house.
- Maximum height of water rise. This indicator is important for the use of equipment for autonomous water intake in a private house and when pumping water to the upper floors of an apartment building.
- Unit size. The dimensions of the station, including the hydraulic accumulator, must correspond to the area of the room where it will be installed.
- Noise level. This criterion depends on the cooling method; a “wet rotor” operates silently, while a “dry rotor” is noisy due to the fan blades.
- Range permissible temperatures. Devices can be for hot, cold water or universal.
- Installation type – vertical or horizontal, the choice depends on the characteristics of the room.
- Reputation of the manufacturer. Products from unknown companies have an attractive price, but their quality is questionable, and service centers none. It's better to buy quality and reliable equipment from a manufacturer with positive reviews.
Well-known equipment manufacturers
DAB offers a compact station with electronically controlled E.sybox mini. It is characterized by the absence of noise and vibration, provides constant pressure in pipes, easy to install. Lifting height – 8 m, capacity – 80 l/min, membrane tank 1 l. The mini unit can easily be placed under the sink.
The model of the German company Wilo PV-088 EA is mounted on metal pipes hot and cold water supply. The maximum pressure rise is up to 8 m, it works in manual and automatic mode. Cooling of the mechanism is carried out by a flow of liquid. Low noise level allows you to avoid discomfort when placed in an apartment.
The Grundfos UPA 15-90 pump operates in three modes: “Automatic”, “Manual”, “Off”. The automatic mode is controlled by a built-in sensor. Manual mode assumes permanent job, therefore it is necessary to monitor the presence of water in the system. The unit is characterized by low noise level and light weight. Its capacity is up to 1.5 cubic meters. m/h, working temperature– 60º C.
Unlike the listed models, the Jemix W15GR booster pump operates on the “dry rotor” principle. The mechanism is cooled by a built-in fan. This design is more productive, but creates noise during operation. It has three operating modes: “MANUAL” - manual, “AUTO” - automatic, “OFF” - turned off. Provides a pressure rise of up to 10 m, productivity – 1.5 cubic meters. m/h.
Installation of a pressure booster pump
Installation of equipment to increase pressure begins with shutting off the water. The work includes the following stages:
- The length of the pump along with the fitting is measured.
- At the installation site, the length of the section is marked and the pipe is cut out.
- WITH outside The resulting ends are threaded.
- Adapters are installed required diameter, the fitting included with the pump is screwed to them. An arrow on the equipment body indicates the flow movement; it is important to install it in accordance with the specified direction.
- To install a separate outlet, a three-core cable is pulled. Grounding must be carried out, and the connection is made through an RCD.
- The water is opened and the pump is checked for functionality. If the connection of the fittings is not tight enough, wrap up the FUM tape.
DIY station
If there is no device with the required parameters on the counter, you can make it yourself from components with the desired characteristics. A pressure boosting station consists of a small number of components and parts; it is enough to purchase a pump, a hydraulic accumulator of the required volume, and an automation unit. A 50-liter storage tank is suitable for a family of three; stagnation of water is also undesirable.
The control system should include:
- smooth pump start;
- dry running protection;
- overload protection.
During installation, all elements of the water pressure increase station are installed in one place.
Tips for choosing and installing a mini pumping station
- Give preference to a model with a check valve; this design increases the safety of the equipment.
- Choose a station with a built-in filter; it will protect parts from foreign particles. If clogged, the element is removed and washed.
- To place the equipment you need warm room, otherwise at negative temperatures the water in the accumulator will freeze.
- To carry out maintenance without problems, install a shut-off valve before the pump.
In contact with
Quite often, the subject of complaints from residents of any private or multi-storey building is low water pressure in the network or simply its absence. The optimal solution This common problem is the booster pump.
This device stabilizes the pressure in the system and makes it possible to provide acceptable living conditions, because without it it is impossible to imagine the functioning of either a shower cabin or a shower.
1 Basic information
Over time, the old standard underwater pipelines lose their capacity and, as a result, they no longer provide the required level of water pressure to residential buildings. By the way, a booster pump or a pump to increase water pressure will be necessary in such a situation; they are suitable for both cold and hot water supply systems.
The equipment compensates for the lack of pressure so that household appliances can work normally. For example, a dishwasher/washing machine “pulls” at least 2 atm; a shower stall requires at least 4 atm. Household water supply does not provide the required value; often you will not get even 1.5 atm. (minimum pressure).
Most often, they use designs that operate in manual (manual pumping pump) or automatic mode. The manual pump operates with a constantly switched on pumping equipment. Automatic is preferable and more economical, since it protects the mechanism from operating in the absence of water and increases service life. He is responsible for operating the pump using a water flow sensor.
Pumping units are installed in private houses, apartments, haciendas, and cottages. The main condition for their uninterrupted operation and reliable operation is correct connection water and electrical systems.
1.1 Operating principle of pumping devices, main parameters
Key parameters to pay attention to:
- switching mode – automatic/manual;
- degree of pressure;
- size. As a rule, all units are compact, which simplifies their connection to the main pipeline;
- noise level. Thanks to the principle of operation, booster pumps operate almost silently, which allows them to be installed in apartments;
- body material is an important parameter, which determines the level of noise emitted during operation, and Maximum temperature water. Stainless steel is a material that provides corrosion resistance and strength.
The principle of operation of water booster pumps is that the equipment system increases the pressure in the water supply network, depending on the pressure in the water circuit. The mechanism takes liquid from a pipe with low pressure, then increases it to the required value, and then delivers it to the flow point.
If you are a resident of an apartment located on the upper floors and centralized water supply"suffers" better advantage give it to a device with a hydraulic accumulator (storage tank) - a pumping station. This is a unit that creates pressure in front of water collection points, equipped with control devices And shut-off valves. The devices are used as large backup units for industrial and domestic purposes. Mounted between the water source and the water supply.
2 Advantages and purpose of booster pumps
Water pumps are used to increase the water pressure in front of the points where water is collected. In other words, a booster pump is used in cases where the water pressure in a residential area is lower than desired. To do this, the device is connected to central system water supply
In the industrial field, booster pumps are also used, but the dimensions of such installations at enterprises are much larger than the dimensions of products designed to increase pressure in living conditions. At the same time, the booster pump in industry is often used only in cases of emergency situations, for example, when there is a need for fire extinguishing.
On to the pros similar units relate:
- compactness;
- low noise level during operation;
- the ability to pump water with high power;
- relatively cheap cost;
- reliability.
2.1 Characteristics and types
This type of equipment is divided according to the type of design, and therefore, devices with different designs may differ significantly from each other. In particular, according to the type of device, pumps that increase pressure can be in the form of self-priming pumping stations, or made in the form of circulation products that increase the pressure level in the pipeline.
Self-priming units consist of a hydraulic accumulator and surface pump, which has the function of sucking liquid. Such equipment is capable of lifting liquid, including in cases where it does not reach the floor on which you live. The water accumulator performs the function of regulating the pressure level in the water supply system. This is achieved through check valves and the air membrane with which the device is equipped. Pressure regulation is carried out using a relay installed in the battery, which, in particular, is responsible for automating the entire process.
3 Selecting a pumping device and installing it
When choosing pumping equipment for your apartment, it is recommended to proceed from the specific parameters and characteristics that a pump must have that can meet your needs. Before purchasing a device, it wouldn’t hurt to seek advice from professionals, as well as consult with someone who already uses similar equipment.
The first thing to do is measure the existing pressure level, which will help you understand what power a future purchase should have. This is important, since you can buy, for example, the most powerful pump, and it will naturally increase the pressure in your pipes, but it may be enough to purchase a product with less power, which will also cope with its task, but at the same time you will not overpay for the device itself, not for the electricity it will consume.
Installing and connecting pumping equipment is not an overly complicated process that requires special knowledge, skills or tools. In most cases, it is enough just to embed the pump into a pipe that is located at the entrance to the water supply system. Circulation products are cut into a certain section of the pipe, then they are well sealed and tightly screwed. When installing circulation modifications, it is important to install the pump in correct position, which must be indicated by the manufacturer on the packaging or in the instructions for the device.
Suction pumps are more difficult to connect, since for installation you must first assemble the device itself, as well as run incoming and outgoing hoses to it, and then connect the hydraulic accumulator to the unit.

All these procedures require high-quality settings, which can only be guaranteed by experienced people. However, some confident users connect the pumping station themselves.
3.1 Installation of a pump in an apartment that increases water pressure GPD 15-9A (video)
Are you familiar with the situation when you open the tap, there seems to be water, but its pressure is so insignificant that you can’t even wash your face comfortably? What can we say about turning on the washing machine, dishwasher or gas water heater. This problem is often faced by both residents of modern high-rise buildings and old houses. The reason here is the low level of pressure in the pipes, and a pump is designed to cope with it, increasing the pressure in the water supply.
This device has small dimensions and can be installed both at the entrance to the apartment and in front of a specific household appliance. In addition, a pump to increase water pressure is used in heating systems to speed up warm-up, save coolant and resist air locks.
Water pump to increase water pressure in an apartment: classification
Depending on the control method, there are:
Manual pump. It has simplest design and a minimum of automation. Installed where continuous operation of the device is required, for example, in a heated floor system. But it requires attention and timely shutdown to avoid overheating.
Automatic water boost pump. Equipped with a flow sensor and starts working immediately after opening any tap. It is a more economical device than hand pump. And thanks to timely shutdown, such a device will last much longer. Therefore, despite the fact that the price of a pump to increase water pressure with automation is higher than that of a model with manual control, in the end it will cost less.
Based on the type of engine cooling, there are:
Pump high blood pressure water with dry rotor. Cooling is achieved without contact with water using impeller blades. This option has high efficiency, but at the same time it is quite noisy. It is better to install it in a separate room using inserts to dampen vibration.
Circulation pump for increasing water pressure with a wet rotor ( flow pump). The rotor has constant contact with water and is cooled by it. The device operates silently, it is economical, durable, and does not require lubrication. The only negative is low efficiency. Therefore, such a water pump that increases pressure is recommended for use in private houses up to three floors high.
According to the type of water passed through, they are distinguished:
The pump for increasing water pressure is universal. Suitable for both hot and cold water.
Pump for hot or cold water only.
