Booster pump for plumbing. Pump for increasing water pressure: an overview of models and main technical characteristics In-line pump for increasing water pressure

The purchase and installation of a booster pump for a water supply system will ensure the stabilization of the water pressure in the system. Old underwater highways (tie-ins) lose capacity over time, cease to provide residential buildings with acceptable water pressure.

This leads to the impossibility of using several points of its consumption at the same time. Installing the device will ensure the functioning of household water appliances, creating conditions for acceptable living.

Application and installation of a water pump for pumping water to a central water supply

A booster pump is used when it is necessary to increase the pressure in an existing water supply connected to a central water supply. It creates sufficient pressure in front of the points of water analysis.

Such devices are also used for industrial purposes in the form of large backup installations that work to extinguish 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 you to operate the entire plumbing system. European standards prescribe its value at 4-4.5 atmospheres. Less pressure will not ensure the operation of the washing machine and dishwasher, hydromassage shower cabin, jacuzzi, geyser.

For a stable water pressure, structures are used that operate in two modes:

manual mode, which involves the operation of a constantly on pump;
automatic mode, which ensures the operation of the pump using a water flow sensor. Such products are preferred. They are protected in the lack of water mode.

Pumps for pumping water are installed in apartments, private houses, country houses, cottages. The main condition for their reliable and proper operation is the skillful connection of the electrical and water systems in accordance with the attached instructions.

The principle of operation of the pump for pumping water

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.

The advantage of an individual heating system in a private house or apartment lies in the short distance the coolant passes from the heating source to the battery. Forced circulation implies the presence of a pump that pumps water through the heating elements: batteries, registers, pipes.

The pump is installed on the return water supply pipe, draining the coolant beforehand or shutting off the available taps on the pipeline. The correct installation of the pump will be indicated by an arrow, the direction of which coincides with the direction of movement of the coolant. After installing the coarse filter and the pump itself, the system is filled with water, removing air by opening the central screw. The unit is connected to the network with a conventional electrical plug.

The booster pump is installed strictly in a horizontal position. It will contribute not only to its quiet operation, but also to prevent damage to the rotor.

Pay attention to the installation of the pump terminal box to prevent water or condensation from entering it. It is strictly forbidden to operate the unit in the absence of a coolant in the system. The pump, equipped with a thermostat, is installed away from water heaters that can affect the operation of the thermostat.

With larger rooms, water consumption increases significantly. Installing one pump may not fully provide the desired pressure. In such cases, several pieces of equipment are installed.

How to choose a booster pump for a private house

When choosing a product, we evaluate the condition of the plumbing system. The choice of the unit of the required power depends on this.

When choosing and purchasing a pump for pumping water, it is necessary to take into account its main characteristics:

performance;
power;
performance;
the size;
guarantee period;
price.

The units differ in technical characteristics and in the method of cooling the engine and housing. Products with a "wet" and "dry" rotor are purchased.

The process of cooling devices of the first type is carried out by the liquid itself. They are silent in operation, but demanding on the quality of the pumped water, requiring constant and timely maintenance.

The motor housing of units with a "dry" rotor is cooled by means of an impeller. They are practical and reliable, although a bit noisy. This type of pumps is in high demand when buying.

Some booster pumps are made with a fixed pressure rise, other models can have several operating modes, are made with several sensors, control units, and can be connected to a control panel.

Stations for increasing pressure are purchased in the absence of water in the taps. The presence of good water pressure from the neighbors below indicates that it does not reach your riser.

You can find out how the installation is done by watching the video:

Installing a pump that increases the pressure in the water supply system ensures the uninterrupted operation of all gas and water appliances, 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.

A drop in water pressure in the pipeline inevitably leads to the fact that any instantaneous water heaters, including gas water heaters, stop working, as well as washing machines that do not have a storage tank. If there is no hot water in the apartment, even taking a shower can be difficult. Proper selection and installation of a special pump eliminates this problem.

What is a water pressure booster pump for?

The water supply system is represented by many pipes interconnected by a large number of taps, tees, elbows and other elements. The presence of a large number of pipe bends helps to reduce pressure, and with increased water consumption by the population and subject to the presence of outdated pumping equipment at stations supplying water, the situation can become catastrophic.

It is from these factors that often the upper floors of apartment buildings remain completely without water during hours when its consumption increases everywhere. If the pressure in the plumbing system drops to below 2 atmospheres, a special pump must be installed to correct the situation.

At the same time, it must be taken into account that in some cases such equipment can only partially improve the situation, and sometimes it is not able to eliminate the problem at all. For example, if low pressure is the result of a clogged or ruptured pipe, it is not possible to cope with this problem by installing a pump. In such cases, only cleaning the pipes and replacing them, if necessary, can correct the situation.

Since the water pump will be used in the future at home, many factors must be taken into account. The first thing you should pay attention to is the power of the device. This is the defining parameter. When choosing a pump, you need to take into account the number of taps and equipment that uses water during operation. Often only powerful devices can meet the needs of residents of an apartment or house.

Existing models of water pressure pumps also differ in the type of control. Some are manual while others are automatic. By increasing the water pressure, any electric pump will create a certain level of noise. This can create some discomfort for residents. When choosing a unit, this parameter must be paid attention to, since many modern models operate almost silently.

In addition, compact models can only be connected to pipes of a certain diameter. Some machines are designed exclusively for cold water supply, while others can be used to pressurize a hot water supply system.

When choosing a pump, you need to consider how much it can raise the water level. This parameter is especially important when choosing a pumping station designed to increase pressure in several apartments of a multi-storey building at once.

To buy a quality device, you need to pay attention to the performance of the device. This parameter determines how much liquid the pump can pump per unit of time. Performance values must necessarily exceed the average water flow.

Some water compressors have additional features, such as a built-in filter. In addition, you need to pay attention to the manufacturer, since devices from companies that have already earned a good reputation, in most cases, are durable.

Varieties of designs of household pumps

All pumps used to increase the pressure in the water supply system of houses, apartments and cottages can be divided into devices with a "wet" and "dry" rotor. Each option has its own characteristics. Pumps used to increase the pressure of water in pipes with a "wet" rotor are compact in size and make little noise during operation, since their internal parts are lubricated by the pumped liquid.

Such devices have a simple connection scheme. In most cases, they simply cut into the water pipe and work like a flow pump. Such pumps are installed in front of the water intake point or in front of household appliances.

Water compressors with a "dry" rotor are characterized by higher performance. Such devices are used in most cases to serve several points of water intake. A distinctive feature of all water pumps with a "dry" rotor is the location of the main electric pump-pump away from the main body and the presence of a separate air cooling system. The rotor does not interact with water.

The best wet rotor pumps

Since there are many varieties of pumps with a "wet" rotor on the market, the selection of such an apparatus can be a certain difficulty for people who are not versed in such a technique. The best models of water pumps with a "dry" rotor include Grundfos UPA 15-90 (N).

This device is equipped with a reinforced body made of cast iron, a terminal box and a flow sensor. Work can be carried out both in automatic and manual mode. The advantages of this device include:

high build quality;
overheat protection;
low noise figure;
resistance to corrosion and wear;
durability;
compactness.

The disadvantages of this model include high cost and expensive post-warranty repairs.

In addition, experts often recommend a pump with a "wet" rotor made in Germany - Wilo PB-201EA. This device has a reliable cast-iron body with a special coating, bronze nozzles, a plastic wheel and a stainless steel shaft. This pump has a mode switch. The advantages of such devices include:

use of materials resistant to corrosion;
low noise level;
the possibility of pumping hot water;
overheat protection;
simplicity in terms of installation;
long service life.

The disadvantages of this apparatus include relatively large dimensions. In addition, such a pump can only be mounted horizontally.

High-quality models of pumps with a "dry" rotor

In some cases, it is advisable to use pumps with a "dry" rotor. The best and at the same time inexpensive devices of this type include the Jemix W15GR-15 A.

This unit has a durable cast iron body, but the motor shell is made of aluminum, and the rotary wheel is made of durable plastic. Using the switch, you can configure such a pump to work in both manual and automatic modes. The advantages of this model include:

high performance characteristics;
ability to withstand high water temperatures;
overheat protection;
dry running fuse;
resistance to corrosion;
relatively low price.

The obvious disadvantages of this model include the possibility of heating during operation. In addition, this unit is very noisy. The service life of this unit is relatively short.

Among other things, noteworthy models of pumps for boosting pressure, characterized by a "dry" rotor, include the Comfort X15GR-15. This model is equipped with stainless steel housing, flow switch and vane cooler. This unit works in both manual and automatic mode. The advantages of this pump include:

small dimensions;
low power consumption;
the possibility of using for pumping water with high temperature;
ease of operation and installation;
resistance to corrosion;
relatively low price.

Please note that this unit makes a lot of noise during operation. In addition, many users note that the power cord of this pump is short, so it is often necessary to use a carrier.

Pumping stations for increasing water pressure

Pumping stations deserve special attention. The Grundfos MQ3-35 model has good reviews. This is one of the best pumping stations designed to increase water pressure. It has automatic control. This device is equipped with an electric motor, a self-priming pump, a hydraulic accumulator. Such a pumping station is controlled by an automatic system equipped with a pressure switch, a protective unit and a flow sensor. The advantages of this device include:

design reliability;
wear resistance;
built-in protection system;
ease of installation;
low noise levels;
durability.

It must be borne in mind that this unit is only suitable for pumping cold water. In addition, in this model the accumulator has a small size.

The Dzhileks "Jumbo" 70/50 N-50 N apparatus is distinguished by good performance. This model has a built-in asynchronous motor, an ejector, a centrifugal pump, a horizontal hydraulic accumulator, a pressure gauge, and a pressure switch. The device has good power and performance. The advantages of this model include.

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

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

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

You are unlikely to need to know the exact pressure in the water supply, so you can use the following ratio, with which it will be easier for you to evaluate the performance of the water supply in your private home:

1 bar ≈ 1 atm ≈ 10 m of water Art. ≈ 100 kPa ≈ 0.1 MPa.

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

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

The solution to the problem of insufficient or increased water pressure in a private house is to install a reducer that equalizes the pressure in the internal wiring of the water supply system, which eliminates the possibility of water hammer. If you do not make mistakes at the stage of selecting and installing the gearbox, then the pressure in the system will always be optimal.

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

Pressure can be measured with a manometer. It is inexpensive, so we recommend that you purchase it and install it on the introductory highway of your private house. It will be even better if you buy a coarse water strainer with a built-in pressure gauge. It is enough 3-4 times a day at certain hours (including peak hours) to record the readings of the device. Then it will be possible to analyze the water pressure indicators in your private house and draw preliminary conclusions.

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

In order to assemble the pressure gauge, you will need a plastic tube approximately 2000 mm long. The diameter of the tube should be such that a tight connection is obtained with a fitting screwed onto the spout of the faucet, replacing the splitter nozzle.

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

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

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

Now we can calculate the pressure:

R in = R o × (h o / h e)

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

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

It is possible that the filters used in the water supply of your private house are very dirty or too old. To troubleshoot, you must perform appropriate preventive maintenance.

Classification of pumps for increasing water pressure in a private house

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

pressure boosting circulation pumps;

self-priming pumping stations for pressure increase.

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

The developers of pumps for increasing water pressure in a private house pursued a specific goal - they wanted to come up with a device to improve the operation of systems with a hot coolant. This is understandable, since the heating circuits are of impressive length, and there is resistance at the nodal connections. Without the use of pumps, such systems will function inefficiently.

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

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

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

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

Pumps to increase water pressure in a private house work in systems:

with cold water;

with hot water.

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

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

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

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

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

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

manual- at which the equipment can work continuously. It will be necessary to monitor the temperature of the pump itself in order to avoid overheating and failure.

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

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

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

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

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

The advantage of a pump with a dry rotor is high efficiency, and with a wet one - noiselessness.

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

Pumping stations

After you check if the pipes of the water supply system are clogged, you can think about purchasing a powerful self-priming pumping station. Pumps for increasing water pressure in a private house can be equipped with a hydraulic accumulator. More often homeowners prefer without it. However, experts advise choosing pumping stations with hydraulic accumulators.

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

It is more profitable for the tank to be large, since the water in it will last for a longer time and, accordingly, the mechanism will be started and turned off less often, the equipment will wear out more slowly. A standard connection diagram for a pressure boosting pump and a diagram for installing a pumping station in a private house with a nearby well are shown below. Note that connection is possible to any available water source.

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

Consider the following when choosing a pump:

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

throughput of pumps and the pressure that it creates;

How reliable is the manufacturer?

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

how much money are you willing to spend to buy such a pump.

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

If you need to slightly increase the pressure (by 1.5 atm.), Then choose a compact pump to increase the water pressure in a private house. It is very easy to mount it.

It can be cut directly into the pipe. Scheme:

Circulation pump.

Stopcock.

Temperature controller.

Safety valve.

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

The very minimum pressure in the system is 2 atm. In such conditions, you can safely wash the dishes and start the washing machine without any problems (note that some models can be “capricious” and refuse to work in such conditions).

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

To get the exact numbers, you will need the help of a specialist. Most likely, it will be enough for him to carry out calculations of preliminary estimated data.

Now it is important to understand what problem you want to solve by installing a pump in a private house. If you can’t take a normal shower when someone is washing dishes in the kitchen, then an ordinary pump will be enough for you to increase the water pressure in a private house (provide an increase of 2 atm.). You probably have some kind of household appliances (the work of which is associated with the pressure of water), so study the instructions for it.

Devices normally work at a certain pressure of water in a private house. If the plumbing cannot provide your expensive equipment with the right amount of water, then it will have to run idle, which will most likely lead to a breakdown of the device that cannot be repaired under warranty.

When choosing a pump, take as a basis the maximum allowable pressure indicators for equipment (data from passports). If you have too many such household appliances, then consult an engineer.

There is an opinion that you should not buy an expensive and powerful pump to increase water pressure in a private house. Proponents of such a judgment argue that a less powerful device should be chosen, connected directly in front of the parsing points and household appliances, the operation of which must be optimized.

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

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

How to install a self-priming pump

Installation of this type of pump is quite simple. You do not need to purchase any complicated tools to install the hardware. You should do the following:

determine the place for the accumulator and pump;

install a hydraulic accumulator;

install pipes for connecting equipment to the water supply;

hang the pump to increase the water pressure to the wall;

tie the pump and accumulator;

check the operation of the pump in automatic mode.

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

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

To save space, you should choose a narrow flat tank, its shape can be arbitrary. Installation should be carried out so that access to it or to the accumulator is maintained (as an option, it can be made so that it can be easily removed if necessary). This is important, as otherwise it will be difficult to maintain, repair or replace the device.

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

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

Now you can start assembling and installing a suction pump to increase pressure in a private house, which, for sure, was bought disassembled.

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

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

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

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

It is important that the connections are tight. If the pump is “screwed” to increase the water pressure in a private house, then there must be a sealant in the required amount in the threaded connection (FUM tape, linen thread). Fittings are required to connect the instrument to plastic pipes.

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

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

Installing a circulation pump to increase water pressure

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

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

Installation of a pump with a hydraulic accumulator

Installing a system equipped with a hydraulic accumulator is somewhat more difficult. Before proceeding with the installation, it is necessary to carefully study the design of the pumping unit to increase the pressure in a private house. The connection of the pump with the accumulator is carried out by special hoses. The pressure switch is responsible for turning the device on and off, which is also connected to it.

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

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

Whichever pump you choose to increase the water pressure in a private house, you will have to additionally purchase pipes, fittings, connections, etc. Give preference only to high-quality products from reliable suppliers.

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

How to choose a pump?

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

If the water in the pipes has less than 2 atmospheres, then not a single device such as a washing machine or a hot tub will work. The minimum value of this parameter for the operation of the entire water supply system is chosen within 2.3 atmospheres. Some pressure boosting pumps have values in the passport expressed in meters of water column. When buying a unit, it must be taken into account that one atmosphere is equal to 10 meters of water column. For fire safety systems, 3 atmospheres are taken as the standard. According to all of the above, pressure boosting pumps should provide an outlet operating water pressure of 2 to 4 atmospheres with fluctuations in this parameter at the inlet from 1.5 to 2 bar.

Varieties of units for flow stabilization

Such a pump for increasing pressure is a flow apparatus, during which an additional force is created, which sharply increases the pressure of the liquid at the outlet. There are several types of a pump that increases the pressure of a liquid in a pipeline:

Household pumps to create a flow of water in a private house or increase the water pressure in an apartment on a high floor.
A garden pump that can raise water from a deep well and is used to water plants in a garden or vegetable garden.
It is possible to install a pump to increase the water pressure in the country, if the central water supply is suitable for this area.

All types of pumps have two modes of operation:

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

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

In order to obtain a high-pressure liquid with flow instability, a hydraulic accumulator is installed in the station, which increases the pressure in the water supply. From its tank, the consumer receives water when the pressure switch turns off the centrifugal pump, when the liquid supply from the central network stops.

What should the consumer consider when buying a pump?

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

The pressure created by the unit and its throughput.
Dimensions of the room or platform on which the pumping equipment should stand.
The reliability of the manufacturer's pump, the device of which the buyer wants to purchase.
The financial possibilities of the consumer himself.

Before you go to purchase the desired pump, you need to contact a specialist who will carry out the necessary calculations for the performance of the unit and the required pressure. By eye, such things are not solved. Most manufacturers of pumping equipment provide such services almost free of charge.

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

If possible, instead of one large pumping station, you can purchase several small units of lesser power, which are usually turned on right in front of the liquid entry points and various household appliances, their work should be optimized as much as possible.

You can buy pumping units at construction markets, in various stores. It is better to go to special branded centers. There the choice is much wider, and there is an opportunity to get a free consultation on the parameters of pumps and their installation, warranty service.

If the house has running water, it is logical to assume that it has water. But, unfortunately, this is not always the case. Sometimes the pressure is so weak that household appliances, unable to withstand such a test, simply refuse to work; in high-rise buildings, water often does not reach the upper floors at all, stopping at lower levels. It is in such situations that pumps will come in handy to increase the water pressure in the system.

How to achieve ideal pressure in water pipes?

Several values are used as units for measuring water pressure in pipes: 1 bar \u003d 1.0197 atmospheres \u003d 10.19 m of water column. According to the regulations, the pressure in urban water supply networks should be 4 atmospheres, but the reality is that the differences can be very significant. Pressure of more than 6-7 atmospheres has a detrimental effect on sensitive imported and domestic plumbing, destroys pipe connections, but even low pressure causes no less trouble. At a pressure of less than 2 atmospheres, neither a washing machine nor a dishwasher can work normally, not to mention a Jacuzzi.

The minimum pressure required for the operation of most household appliances ranges from 1.5 to 2.4 atmospheres; in fire extinguishing systems, the requirements are more serious - at least 3 atmospheres. If the indicators in the system are much lower, for example, because the apartment is located on the top floor of the building, or because of the large water intake, then it becomes necessary to use special means (boosting installations) that would maintain the required pressure level.

Before selecting a high pressure pump, it is necessary to specify the problem. The most frequent complaints are:

tap water flows, but the pressure is so weak that there is no question of any comfort;
There is no water only on the upper floors of the building, on the lower - everything is in order.

In the first case, a water pressure booster pump can serve as a solution to the problem. In the second, he will be powerless, he will have to fork out for the purchase of a self-priming unit.

A pumping station can solve pressure problems in most cases, but you need to know how to connect this equipment

The choice is very individual, depending on the need for water and several other important factors. Before that, you need to make sure that it is a matter of insufficient pressure, and not clogged pipes, because, due to lime deposits or mechanical particles, the diameter of the pipes can become much smaller over time, then the pump will not help, the water supply will need to be replaced. If the problem lies, indeed, in a weak pressure, then the equipment will be useful.

Model classification

So, when choosing, they take into account whether it is necessary to simply increase the weak pressure or to understand the water from the lower floors to the upper ones. In the first case, you will need a small device in terms of power and size, of an “in-line” design, which is simply mounted in a pipeline, in the second, a high-pressure centrifugal water unit with a hydraulic accumulator. They operate in one of two modes:

Manual mode - ensures continuous operation of the equipment. It is necessary to ensure that it does not overheat and does not fail, turn it off in time.
Auto mode. With it, the flow sensor regulates the work. As soon as the faucet is turned on and water begins to flow, the pump turns on. This mode is preferable to the first mode, in which the water pump for increasing pressure is protected from running in dry mode (in the absence of water), which means it will last longer. The automatic option is more economical.

There is also a classification of pumping equipment according to the method of cooling the casing. It can be carried out using the motor impeller or using the pumped liquid:

Cooling by shaft-mounted vanes, so-called dry rotor design. These motors are characterized by high efficiency and low noise during operation.
Cooling by pumped liquid, so-called wet rotor. The unit with such a cooling system operates almost silently.

For the user, the size of the pump is also of no small importance, because it is often necessary to install equipment in small rooms.

Dry rotor pump boasts high efficiency

In contrast to the previous one, the wet rotor pump runs silently

Usually carried out at the entrance to an apartment or house. It is important to take into account that there are universal pumps that can be used for cold and hot water supply systems without any hesitation. And there are those that are used only for either cold water or hot water.

"Heavy artillery": how to choose a household pumping station

If you are convinced that the pipes are not clogged, and the water simply does not reach your floor, then you will have to acquire a more powerful unit - a self-priming pumping station. The pump can be installed with or without a hydraulic accumulator. Many owners of small apartments choose the latter option, but experts strongly recommend choosing the former, even with the smallest tank.

The pumping station will allow you to "raise" water from the ground floor or from a well

The station itself is a surface centrifugal unit for increasing water pressure, which is connected to a hydraulic accumulator and a pressure switch that controls the entire system. With its help, water is taken from the system and supplied to the tank. Even after the pressure switch turns off the pump, the consumer can use the stored water, which is very convenient if the water is often turned off. In this case, the pressure will drop. As soon as it drops to a certain level, the relay will work again and the pump will turn on again. It is easy to guess that the larger the tank, the longer the equipment lasts, since it turns on and off less often.

What to consider when choosing a specific unit for a house or apartment

So, when choosing pumping equipment, it is necessary to take into account several important points:

the assigned task;
characteristics (capacity and generated pressure);
the authority of the manufacturer;
the dimensions of the room in which the equipment is planned to be installed;
the amount to be spent on its acquisition.

Without knowledge of the required performance and pressure, it is very difficult to make the right choice. It is better to entrust all the necessary calculations to a specialist. Many companies that sell such equipment provide such a service for free.

If you just need to slightly increase the pressure in the system, by about 1.5 atmospheres, then the compact pump, which can be easily and simply inserted directly into the pipe, is ideal. Scheme (to the photo): 1 - Circulation unit; 2 - Filter; 3 - Shut-off valve; 4 - Temperature controller; 5 - Safety valve.

Compact booster pump can be plugged directly into the pipe

Some experts consider the installation of an expensive and powerful pump unnecessary. In their opinion, a more rational option is several devices of lower power, which are connected directly in front of the points of analysis and household appliances, the operation of which must be optimized.

Buying pumping equipment to ensure good water pressure in an apartment or house is not a problem, it is widely represented in household appliances stores, online stores, and construction markets. But it’s better to go to a branded salon, where there is a wider choice, there is an opportunity to get expert advice, and there is a warranty service, which is especially important for those who purchase an expensive model.
