Household pump to increase the water pressure in the apartment. The best pumps for increasing water pressure according to customer reviews. Pump Selection Criteria

The plumbing system at home is a rather complex structure designed to provide high-quality water supply. The indicator of the quality of operation of the entire water supply system is characterized by a single indicator - water pressure. Pumps to increase water pressure in a private house help you set the pressure indicators that are necessary for the convenient use of household appliances.

Why pumps are needed to increase pressure

According to the normative documentation, the pressure in water supply communications should correspond to the parameters of 3-6 atm. As practice shows, with a pressure of less than 2 atm., The operation of equipment (dishwasher, washing machine and water heaters) stops.

High-quality operation of various household appliances, as well as fire hydrants, is possible only if there is a water pressure level of at least 2 atm. In cases where this indicator does not correspond to the norm, special devices will come to the rescue, designed to provide the necessary pressure in the pipes.

These technical devices include:
1. Pressure booster pump.
2. Pump station.

Let us consider in more detail the principle of operation of the pump to increase the pressure of water. This device is used when there is water in the plumbing system, but the pressure level is so low that the quality of the plumbing is simply impossible. In practice, this problem is quite common in multi-storey buildings, where residents of the upper floors often sit without water due to the very low pressure in the plumbing system. A good way out of such an unpleasant situation would be to install a pump to increase the pressure level.

Before installing this device, you should carefully study the problem and identify the causes of low pressure. These include corrosive damage to the inner surface of pipes or plugs from organic deposits that appear as a result of improper maintenance of the plumbing system and poor quality of the water supplied. With such problems, the use of a pump is not entirely justified, since, having eliminated problems, the pressure returns to normal very quickly.

Depending on destination These devices are divided into:
- Operated with a certain type of water (cold or hot)
— Universal.
Depending on the cooling method pumps are divided into:
— Dry rotor. Cooling occurs due to blowing by a fan, which is mounted on the shaft.
— Wet rotor. Cooling occurs due to the pumping of liquid by the impeller, which, together with the rotor, is lowered into the water.

Operating mode options pump help to divide the devices into the following types:
- Manual pump. The device is constantly running. Adjustment of work occurs only manually. It is very important when using this device to avoid overheating;

What are the benefits of using a high pressure pump

1. Relatively compact dimensions.
2. Light weight.
3. Silent operation of the motor.
4. Installation of the device is carried out directly on the pipes of the water supply system.
5. Low cost.

What to look for when choosing a high pressure pump

You can buy a quality device in stores, retail outlets in construction markets or on the Internet. All detailed information about the pump can be easily obtained from the seller if you want to install it.

Pumping station

However, when making a purchase, you should still pay attention to the following technical indicators:

device performance;
power and pressure;
noise level at work;
operating temperature range.

Of course, the higher these indicators are, the more effective the device can be. Do not forget about the pricing policy. As a rule, the cost largely depends on the brand of the manufacturer, the materials of manufacture, and the technical parameters of the device. Choose a pump to increase pressure, taking into account the characteristics of water communications in your area.

The benefits of any apartment buildings are efficient communication systems, which include plumbing. The operation of household appliances, such as a boiler, washing machine or dishwasher, depends on the quality of its functioning. In some situations, the installed pump helps to increase the water pressure. It pumps the required level in the system, providing a continuous powerful flow.

A booster pump will be the best solution for the local level. It is mounted within the apartment and is designed to serve one household. The installation of such equipment will become effective if the problem lies solely in the lack of pressure, but at the same time all the pipes are not clogged and the rest of the supply system is fully operational.

The need for arrangement

Pumps to increase water pressure are introduced into the home hydraulic system, often on the upper floors. There, the established norm often reaches the planned values. The optimum is an indicator reaching 5 bar. However, in reality, the value in the pipeline sometimes drops to the level of 1 bar.

Such parameters are unacceptable, since in this situation automatic washing machines that require at least 2 atm may not even start. It will be possible to take a shower in the shower cabin only at 3 atm. Approximately 2-2.5 atm is needed to start the boiler. The jacuzzi will be in working condition at 3-4 atm.

Operating parameters of connected equipment

Before connecting, you need to figure out which booster pumps for water have characteristics. The difference in them happens in the way they start:

User launch option. The hydraulic apparatus is stably turned on / off by the owner. It is enough for owners to control the presence of liquid in the system, since operation without water leads to a quick failure from overheating. Often a feature of the operation of such schemes is one-time operations with subsequent shutdown.

Models for pumping water with automation installed in the system, thanks to special sensors, are connected independently as needed.

When choosing equipment, you should pay attention to the ability to transport a stream of a certain temperature. Structural features are manifested in the possibility of passing water in a limited temperature regime. In specialized outlets or on the websites of online stores, you can find the following types of devices:

units capable of working exclusively with cold systems;
models designed to be included in hot flow wiring;
universal equipment designed to interface with any liquid temperature.

A well-functioning pump, which should not overheat significantly during operation, helps to maintain the stability of the pressure level.

Cooling systems help to get rid of overheating.

According to this type, productive models are divided into the following groups:

The temperature is lowered by the flow passing through the housing. This technique is called the "wet rotor" method. It has minimal noise parameters, but is capable of overheating when operating without water.

For cooling, rotating blades fixed on the shaft are used. The method is called "dry rotor". The disadvantage is the increased noise during operation. The disadvantages are offset by a fairly high degree of performance, which the pump for water pressure has.

Introduction of step-up stations

For owners of apartments, from the upper levels, it is advisable to install a pumping station. Self-priming equipment includes the following elements in the circuit:

hydraulic pump;
manometer;
relay;
hydraulic accumulator.

The principle of operation of the unit is to pre-fill the accumulator, set the desired outlet pressure on your own using a relay, and start the pump, which ensures the distribution of fluid to consumers.

In some schemes, it is proposed to exclude the accumulator, however, this approach will negatively affect the duration of operation of the entire pressure unit. It is advisable to choose a larger tank that will fit into the interior of an apartment or house, as this will allow you to turn on the boost system less often.

After the volume is pumped into the tank cavity, a shutdown occurs. In this case, the consumer receives a jet from the accumulator even in the situation when there is no water supply in the system at the moment. If the liquid is completely out of the tank, the relay will automatically turn on the pumping.

Before purchasing a station, it is recommended to clarify its maximum pressure. You can use the popular model Grundfos JP Booster 6-24L, which will provide a pressure of 48 m and has a considerable tank with a capacity of 24 liters. Its cost is approximately 24 thousand rubles.

How to choose the right pump to increase water pressure

When choosing the right booster pump, there are important factors to consider:

Power characteristics. The more productive the unit is, the wider the number of points that it can effectively serve. In the calculations, it is necessary to monitor the number of consumers, washers and plumbing fixtures.
Noise. Of course, less noisy devices are preferable, but they may have a higher cost.
Patency. It is important to pay attention to what diameter of water pipes the pump can be combined with. Working sections are specified in the user manual. Failure to comply with this parameter can lead to work with overloads, breakdowns and a decrease in pressure below the calculated value.

Appliance device

lift height. When buying a pumping station with a lower load, it may not reach the required level.
Equipment dimensions. The hydraulic assembly must fit neatly into the allotted space.
Reliability. It is preferable to choose proven well-known brands that have a long warranty period.

VIDEO: What is the difference between a vortex pump and a centrifugal pump

The main selection criterion is the outlet pressure indicator, which should not be less than 4 barrels. Further, they are already determined directly with the characteristics of the electrical appliance - dimensions, noise level when turned on, wet or dry, etc. Since we are talking about a high pressure pump, for many it will be a matter of principle - manual or automatic control.

Pumping equipment for hot water supply is different from that which is installed in a system with cold water.

In most cases, when choosing, preference is given to well-known brands. Having overpaid, relatively speaking, just for the brand, the user receives high-quality working equipment and warranty obligations, which the seller or the manufacturer will definitely fulfill.

Among the priority companies:

WILO- the leader in consumer demand according to reviews and store statistics. It is considered elementary in operation, has been operating for more than 7 years in extreme conditions and is very reliable in operation.

Grundfos- in some regions, even Vilo bypassed. The obvious pluses are silent operation and low weight. The factory warranty is 12 months.

OASIS- easy to operate, high-quality equipment, which is only striving for the TOP-10, but has not yet come close.

The leader of domestic production, although it does not enter the European market. All without exception are compact and low-noise. Branch pipes for installation are unified for Russian water utility systems.

Wiring diagram - right and wrong

Water low-pressure pumps on collectors work non-stop. In order for the pressure to increase gradually (in steps), a multi-wheel system is used. During operation, the device is able to create a pressure in the system up to 10 bar.

VIDEO: Why is it needed and how to assemble a storage tank

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.

The operation of many types of plumbing equipment and household appliances directly depends on the pressure in the water supply network. If it is low, then this fact is a real problem, especially in high-rise buildings.

The only way out of this situation is to use a pump that increases the pressure in the water supply. Otherwise, living in such an apartment or house becomes extremely uncomfortable.

The rate of pressure in the water supply

The unit of this indicator is bar. Another name is atmospheric unit. Physically, this can be interpreted as the rise of water under such pressure to a height of 10 meters.

In the networks of settlements, the pressure, according to the standards, should be 4-4.5 atmospheres, which ensures the maintenance of high-rise buildings.

In accordance with the current standards given in SNiP 2, 0401-85, cold water in the system should be within 0.3-6.0 atmospheres, and hot - 0.3-4.5. But you need to understand that extreme values \u200b\u200bare given in it and this does not mean at all that with such extreme values \u200b\u200bthe plumbing will function normally. In such circumstances, pumps are used to increase the pressure of the water in the water supply.

Excessively high pressure in the water supply network is no less dangerous than insufficient. So, if this indicator reaches a value of 6.5-7.5 atmospheres, extreme conditions are created for the operation of the compounds.

In plastic pipelines, threaded connections and joints created by soldering begin to let water through, forming leaks. In such conditions, it is necessary to carry out installation only with welded metal fittings.

It should be noted that flowing artesian wells can give pressure up to 10 atmospheres and in such circumstances it is necessary to use pressure regulating apparatus.

Causes of low water pressure

The circumstances leading to a drop in pressure in the water supply network can be both objective, resulting from natural processes, and subjective, associated with errors in design, calculations, and selection of equipment. They can be formulated as follows:

Increased water abstraction associated with high seasonal consumption. This happens in the summer when private sector consumers use large amounts of water to water vegetable gardens.
Faulty or underpowered pump at distribution station.
Clogged pipes. In the case of using metal water pipes, this may be rust mixed with naturally occurring lime insoluble deposits.
Leaks of water on gusts or leaks in the water supply. They are formed mainly at the joints of pipes or corrode their walls through and through. The only way to avoid such defects is to carry out periodic inspections and current repairs strictly according to the developed schedule.
Insufficient capacity of electrical networks feeding the substation.

For the private sector, using individual water intake in the form of wells or boreholes, this becomes possible due to a gradual decrease in their flow rate as a result of silting of sources, clogging of filters.

The most unpleasant thing is that the factors that reduce the pressure in the water supply do not occur at one moment, their influence is significantly extended over time and is not noticeable. Obviously, constant control over the throughput of the pipeline is needed.

How does a booster pump work?

The most common signs of insufficient pressure in the water supply are low pressure from the tap or the inability to use two or more water points.

This becomes a reality already when the pressure drops closer to the minimum standard value.

If it is checked and established that the water pipes are in good condition, it is necessary to install pumping units to increase the atmosphere in the water supply network. For this, centrifugal devices driven by an electric motor are used.

Performing the same functions - maintaining water pressure in the water supply system - they may differ in the principle of operation:

Permanent devices - they work around the clock in continuous mode, maintaining water pressure in the system. The disadvantage of this type is the constant consumption of electricity and accelerated wear of equipment. Such devices do an excellent job when turned on in manual mode during peak loads on the water supply, for example, while watering the garden.
The pump is automatic, equipped with a flow sensor. Its inclusion is carried out in the presence of water movement through the pipe, which indicates the presence of flow at a given time. This mode of operation is more economical than in the previous case. The cost of an automatic pump to increase the pressure in the water supply is somewhat higher, but this is offset by a more economical mode of operation.

A significant difference for such equipment is the method of cooling. In devices dry rotor the impeller is located in a separate chamber and is separated from the water flow by glands installed in the housing.

Watch the video

Pumps wet rotor work directly in water, which has a positive effect on their durability, since the liquid is both a cooling agent and a lubricant for the bearings.

The main advantage of such devices is noiselessness in operation. This allows them to be installed indoors.

Pump power selection rules - technical characteristics, their meaning

The main factor influencing the choice of a device for supplying water and maintaining normal pressure in the system is the nature of the water intake point:

The self-priming unit is used in conditions where the water intake point is located below the installation level of the unit. Structurally, they are designed in such a way that they are able to independently suck up water at a distance of up to 8 meters in depth.

The shorter the distance from the water to the pump, the more efficiently it takes water, so the installation site should be as close as possible to the source.

Normally suction units are installed in the water supply system and maintain pressure in it, while the source of water intake, as a rule, is located above the unit itself. It can be an inlet pipe or a water storage tank.

A separate line produces circulating devices designed to provide accelerated circulation of the coolant in heating systems. They are equipped with a temperature sensor to automatically adjust the flow rate. The place of their installation is the return pipe of the heating circuit.

Well pumping devices are used to supply water and maintain pressure from large tanks and wells. The design of such a device provides almost complete noiselessness during operation. Air suction is not allowed when the water level drops. This is guaranteed not to happen if the unit is equipped with a device for automatic shutdown at a critically low liquid level.
Submersible borehole pumps are designed for installation in confined spaces, determined by the diameter of the water intake casing pipe. Therefore, their diameter is small, and the performance is high enough to meet all the needs of consumers.

How to choose a pump based on hydraulic characteristics

The main indicators when choosing are the following indicators:

Q- device performance, measured in cubic meters per unit of time - m 3 / hour;
H- head value - the height of the water column, measured in meters.

These two indicators determine the performance of the device. They are interdependent; when any of them changes, the second also changes accordingly.

For a country house for 4 people, it is 1-2 cubic meters per hour.
When using water for irrigation of the site - 2-3 cubic meters per hour.

The pressure indicator required for the water supply network can be determined with sufficient accuracy from the ratio:

H = H geo + (0.2 +L) + 10 (m), where:
H- pressure;
H geo;
L – the total length of the discharge and suction pipes;
10 - the minimum value of the required pressure at the draw-off point.

Using the selected indicators and the calculation performed, you can select a device that meets the requirements of a particular water supply network.

The pressure of the selected pumping unit must ensure that it performs the following functions:

Raising the water column from the suction point to the required height.
Overcoming the hydraulic resistance of the pipeline, including the pipes themselves, fittings, measuring instruments and control equipment.
Obtaining the desired pressure at the end point of consumption. To do this, you need to lay a margin to the calculated result, adding another 10-12 meters.

The characteristic indicating the height of the pole is a passport parameter and is always indicated in the accompanying technical documentation.

Watch the video

If the distance between the building and the water intake point is 25-28 meters, you should opt for a submersible pump instead of a self-priming one.

Selection of a booster pump based on technical specifications

Domestic pumping stations are used to organize water supply for private buildings. Such units are capable of producing water intake from various sources - tanks, wells, well water intakes or natural reservoirs. Of the positive aspects of using such a device, the following can be noted:

The systems maintain the same pressure in the piping, which allows the operation of various household appliances and plumbing equipment in the house.
There is no need for regular monitoring of the station - the built-in automation ensures the operation of the device for a long time.

Household pumps are demanding on a sustainable power supply.

The main nodes of such a device are:

hydraulic accumulator;
surface or submersible pump;
relay for pressure control;
liquid return valve on the water intake;
power supply and adjustment device.

A hydraulic accumulator is a vessel in the form of a cylinder, divided inside by a flexible partition. In the production process, gas is pumped into one compartment at a set pressure.

Water enters the pipework through the accumulator, at which time the pumping unit constantly pumps liquid that acts on the flexible connector. When the set value is reached, the membrane acts on the pressure control switch, pumping stops.

When one or more taps are opened, the pressure in the vessel decreases and water is pumped again by the pump.

It is this unit that is the main unit of the station and the operation of the entire installation largely depends on its characteristics.

Pumps that increase the pressure in the water supply

As delivered, automatic stations are equipped with external pumps. They are installed on a metal base - a frame along with hydraulic accumulators and control units. A water intake pipe is connected to the inlet of the pump, which is immersed inside the casing, into the throat of a crinica or other water intake.

The standpipe system allows this device to be installed in wells with a narrow casing.

By design, the pumps are vortex or centrifugal action. The first create suction of water due to the rotation of the rotor with blades located directly in the housing.

They work almost silently, which determines their main use as a pump to increase the pressure in the water supply, built into the piping inside the house.

Such units are used in systems operating only at a positive liquid temperature. When defrosted, they simply become unusable.

Centrifugal pumps produce a lot of noise during operation, but they are able to pump water from deep aquifers. In addition, they are operational even at negative temperatures, so they are installed either in separately located buildings or in a borehole caisson.

Hydraulic accumulator device, characteristics

As mentioned above, the water supply to the house when using pumping stations is carried out indirectly through a hydraulic accumulator. Such a device equalizes the pressure in the system and protects it from hydraulic shocks when the pumping is turned on.

Watch the video

An important indicator for a battery is its capacity. The larger it is, the less often the station pump turns on, which increases its service life and saves electricity.

Installation and connection of the booster station

Location of booster pressure device, always selectable closer to the water source. In the second case, you need to open and equip a special bunker - a caisson.

Video installation
Watch the video

The depth of such a container should be at least 2 meters. On the bottom, you need to make a water seal from clay, and overlay the walls with bricks or arrange a concrete wall.

It is also possible to install a pumping system in a separate room inside the house if a silent unit is used.

When installing a water intake in a well, you need to make a special shelf on its wall, on which the equipment is placed.

In houses with periodic visits (dachas), the equipment is usually dismantled for the winter and placed in storage in the house.

Watch the video

Since the depth of the well often exceeds the capabilities of the suction pump (8-9) meters, a station with a submersible or ejector pump is used for them, which allow water intake at a well depth of up to 45 meters. But such equipment will cost a little more.

Popular Models

Currently, one of the market leaders in pumping equipment is the brand Gilex. Very democratic in price - from $ 100 - they are quite durable and reliable in operation.

The pumps are available in cast iron, polypropylene and stainless steel housings. The latter option is slightly more expensive, up to $350, which is offset by higher reliability. The volume of the battery is 24 liters.

The submersible pump option can cost up to $500 and reliably pumps water from depths of up to 32 meters at up to 1,200 liters per hour.

Popular in the market and swap stations Grundfos. They are produced in metal chrome-plated cases with hydraulic accumulators of 24 and 50 liters. Stations are almost silent in operation and are distinguished by enviable durability.

A significant drawback of the Grundfos supply policy is the lack of spare parts that are not supplied to our country. So, any malfunction of the equipment leads to the need for its complete replacement.

Prices at Grundfos station start at $250. These are low power units - from 850 watts with an external pump with a lift of 8 meters and a capacity of up to 3700 liters per hour.

Higher power equipment, up to 5000 liters with a 1.5 kW pump, already costs twice as much - about $ 500.

The Grundfos family with stainless steel cases starts at $450, and packages are available for $1,200. But they are equipped with many features: protection against overheating and idling, as well as water cooling.

Good feedback comes from consumers of plumbing equipment vilo. These are stations of higher power, designed for water supply of fairly large objects, while the control circuit has the ability to steplessly adjust all the main parameters.

Management is carried out through the active display using a programmable processor. The equipment is very solid and the cost of 1000-1300 dollars in this case is fully justified.

It should be noted that up to 4 surface pumps can be installed in a pumping station of this type.

The choice of booster pump in the water supply

It is impossible to create conditions for comfortable living in a country house without a reliable water supply device. In modern plumbing systems, it is also impossible to do without a booster pressure pump in the water supply.

What you need to consider when choosing, taking into account the cost of electricity and to meet the need for clean water. Let's consider some points:

The pump used in suburban water supply systems must provide not only the direct needs of residents, but also such as watering the garden and the site. And in the presence of a pool - its filling and functioning.
For a small country house and in the presence of nearby groundwater, the installation of a surface pump should be preferred. Its performance is sufficient for domestic and irrigation needs.
Deep waters may require the use of an ejector pump. If there are no other options, you will have to take care of the caisson equipment, since such equipment produces a lot of noise.
In a private water supply system, a storage tank is needed, which is often located in the attic. At the same time, an automatic water refilling device and overflow control are extremely necessary, otherwise the house can be flooded.
The ideal solution to the problem of water supply can be considered the installation of a pumping station with all the necessary adjustments.

The pressure in the water supply when using a washing machine or hot tub must be at least 4 atmospheres.

Reading 7 min.

Quite often, the subject of complaints from residents of any private house or multi-storey building is low water pressure in the network or simply its absence. The optimal solution to this common problem is a booster pump.

This device stabilizes the pressure in the system and will make it possible to provide acceptable living conditions, because without it it is impossible to imagine the functioning of either the shower or the shower.

Basic information

Over time, the old standard underwater lines lose their capacity, as a result of which they cease to provide residential buildings with the necessary level of water pressure. A booster pump or a pump to increase water pressure will, by the way, be in such a situation; they are suitable for both cold and hot water supply systems.

The technique 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 plumbing does not give the required value, often you will not get even 1.5 atm. (minimum pressure).

Most often, designs are used, the operation of which occurs in manual mode (manual pumping pump) or automatic. The manual pumping pump provides for the operation of constantly on pumping equipment. Automatic is preferable and more economical, because it protects the mechanism from working in the absence of water, increases the service life. He is responsible for operating the pump using a water flow sensor.

Pumping units are installed in private houses, apartments, haciendas, cottages. The main condition for their smooth operation and reliability of operation is the correct connection of water and electrical systems.

The principle of operation of booster devices, the main parameters

The main parameters to pay attention to:

switching mode - automatic / manual;
degree of pressure;
the size. As a rule, all units are compact, which simplifies their connection to the main pipeline;
noise level. Due to the principle of operation, booster pumps operate almost silently, which allows them to be installed in apartments;
case material is an important parameter, on which both the noise level emitted during operation and the maximum water temperature depend. Stainless steel is a material of execution that provides resistance to corrosion and strength.

The principle of operation of booster pumps for water is to increase the pressure in the water supply network by the equipment system, depending on the pressure in the water circuit. The mechanism takes liquid from a low-pressure pipe, then raises 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 the centralized water supply is “suffering”, it is better to give preference to a device with a hydraulic accumulator (storage tank) - a pumping station. This is a unit that creates pressure in front of the points of water analysis, complete with control devices and shutoff valves. The devices are used as large backup installations for industrial purposes, everyday life. Mounted between the water source and the water supply.

Advantages and purpose of booster pumps

Pumps that pump water are used to increase the water pressure in front of the points at which the water is parsed. 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 the central water supply system.

In the industrial field, booster pumps are also used, but the dimensions of such installations at enterprises far exceed the dimensions of products designed to increase pressure in domestic conditions. At the same time, the booster pump in industry is often operated only in cases of emergency situations, for example, when it becomes necessary to extinguish a fire.

The advantages of such units include:

compactness;
low noise level during operation;
the ability to pump water with high power;
relatively cheap cost;
reliability.

Characteristics and types

This type of equipment is divided according to the type of construction, and therefore, devices with different designs can differ significantly from each other. In particular, according to the type of device, pumps that increase the pressure can be in the form of self-priming pumping stations, or they can be made in the form of circulation products that increase the pressure level in the pipeline.

Self-priming units consist of a hydraulic accumulator and a surface pump, which has the function of liquid suction. Such equipment is capable of lifting liquid, including in cases where it does not reach the floor on which you live at all. The water accumulator performs the function of adjusting the level of pressure in the plumbing system. This is achieved by the check valves and the air membrane that the device is equipped with. Pressure adjustment is carried out by means of a relay installed in the accumulator, which, in particular, is responsible for automating the entire process.

They consume more electricity than circulation pumps. The minimum consumption of such a unit starts from 2 kW per hour, however, this indicator pays off with the power that they possess. So, for example, when consuming two kilowatts per hour, the pump is able to lift water from a depth of 12 meters, doing it efficiently and quickly. The cost of such devices is often lower than circulation pumps.

Circulation plants are divided into those that work with cold water and those that pump hot liquid. For pumping cold water, simple modifications are made, made of inexpensive plastic. They do not withstand prolonged contact with hot water and can pump liquid with temperatures up to +40 degrees.

Models designed to work with hot liquid are most often used for installation in hot water or heating systems. Such products are made from more expensive metals, such as stainless steel and high quality rubber gaskets.

Circulating devices consume several times less electricity than pumping self-priming stations, however, their power, respectively, is much lower. They in most cases require no more electricity than an electric light bulb. Circulation pumps increase pressure by 2-4 atmospheres and can pump around 2-4 cubic meters of liquid per hour. At the same time, some models are equipped with more powerful engines, and therefore, their performance indicators may be higher.

Such circulation pumps are called because they contribute to the formation of circulation in water supply systems. These products are small and very compact. For installation, they are cut into certain sections of the pipeline.

The choice of a booster device and its installation

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. It does not hurt to consult with professionals before buying a device, as well as consult with those who already use such equipment.

The first thing to do is to measure the current level of pressure, which will help you with an understanding of how much 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, however, 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 any for the device itself, nor for the electricity that it will consume.

Installing and connecting booster equipment is not a very complicated process that requires special knowledge, skills or tools. In most cases, the pump just needs to be inserted into the pipe, which is located at the entrance to the water supply system. Circulation products cut into a certain section of the pipe, then they are sealed with high quality and tightly twisted. When installing circulation modifications, it is important to install the pump in the correct position, which should 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 inlet and outlet hoses to it, and then connect the hydraulic accumulator to the unit. At the same time, pumping stations, as well as circulation pumps, crash into the water supply system. All these procedures require high-quality adjustment, which can only be guaranteed by experienced people. However, some self-confident users connect the pumping station on their own.
