The water supply is sufficient complex system pipes, valves and taps, which should uninterruptedly supply water to consumers. The quality of operation of these systems is assessed by such technical parameters as " water pressure".

According to the current standard The water pressure in the water supply network must be within 3…6 atmospheres. It is known that when the water pressure in the pipes less than 2 atmospheres Job household appliances(dishwashers and washing machines, water heaters...) n not possible. If the water pressure in the pipes is 7 atmospheres or more, That plumbing fails and pipe joints are destroyed.

Therefore, the constant availability of the required water pressure within specified limits is one of the most important tasks in the development and further use of water supply systems. Solving this problem is especially important at the design stage of water supply systems. . Indeed, during their design, it is necessary to take into account a huge number of factors, ranging from the number of consumers to the average hourly water consumption of each facility, be it apartment house, enterprise or any other consumer.

In practice, it is extremely difficult to balance the influence of all existing factors, so in reality we have unbalanced water supply networks. Hence the constant problems with the supply of water to the population.

Why do you need a pump to increase water pressure?

The minimum water pressure that must be present in the pipes is 2-3 atmospheres. This level of water pressure provides normal operation household appliances , fire hydrants, etc. If the water pressure does not meet this requirement, it is necessary to use special devices that provide the specified level of pressure. These devices are:

• Water pressure booster pump .
• .

Boost pump water pressure in the house is used when there is water in the system, but the pressure is so low that its use is impossible. If on the first floors of the house the pressure is normal, but on the last floors there is no water at all, then a solution to the problem is possible by using a self-priming pumping station.

When choosing a device that will help solve existing problem, at first you need to determine the cause of the low pressure . Low blood pressure often occurs when corrosion of water pipes or if they clogged with organic deposits. In this case, in use additional equipment not necessary - pipes need to be changed urgently. If the problem is still low pressure, then a water pressure pump in the house will help get rid of it.

Self-priming pump station It is assembled on the basis of the same pump to increase water pressure, which is connected to a hydraulic accumulator and uses a water pressure switch for the pump to control the entire system. In this case, water is pumped into the storage tank.

Classification of water pressure pump models

There are several options for classifying water pressure pumps:

• by appointment;
• by cooling method;
• according to operating mode.

According to their purpose, pumps are divided into:

• used only for one type of water (cold or hot);
• universal , used for any type of water.

Depending on the cooling method, pumps are:

• air cooling (dry rotor). The pump motor does not come into contact with water, and cooling is carried out by fan blades mounted on the shaft;
• water cooling (wet rotor). The rotor with impeller is placed in water and isolated from the stator with a special glass. Cooling of the motor is provided by the pumped water.

Operating modes of water pressure pumps:

• auto . The pump operation is controlled by a flow sensor. The pump is activated when any tap is opened and turns off when it is closed;
• manual . The pump runs continuously. The pump is turned on and off manually, but it is important to avoid overheating the motor.

Advantages and disadvantages of conventional types of pumps and pumping stations

In general, equipment for increasing water pressure has advantages and disadvantages characteristic of this type of equipment:

1. Pumps high pressure for water.

Advantages:

• small sizes;
• light weight;
• quiet operation;
• installation directly on a water pipe;
• low cost.

The disadvantage is the inability to increase water pressure by more than 1 atmosphere.

1. Pumping stations.

The main advantage is the provision required level water pressure. Provides the ability to fully meet water supply needs apartment building, private country cottage or cottages in automatic mode (if there is a water pressure switch for the pump).

Flaws:

• technically complex installation;
• large dimensions;
• relatively loud noise;
• Availability separate room for installation;
• high price.

Models and characteristics. Which pressure pump is better?

How to choose a pump to increase water pressure

You can buy a high-quality pump to increase water pressure in supermarkets building materials, specialized retail outlets for the sale of plumbing fixtures, as well as through online stores. Wherever pumps for increasing water pressure are sold, a potential buyer will be able to familiarize himself in detail with the operational parameters and receive qualified advice on all issues of interest to him.

When choosing a pump to increase water pressure in the house, you need to pay attention to the following: technical specifications , How:

1. Maximum power and pressure.
2. Maximum performance.
3. The level of noise created during operation.
4. Operating temperature range.

The cost of water pressure pumps has a wide price range and depends on:

• manufacturer's brand;
• productivity;
• production technologies and materials used.

ATTENTION! Solving the problem: “How to choose a pump to increase water pressure?” We must not forget that water pressure pumps increase the pressure by no more than 25-40%. Therefore, their use is justified if the water pressure in the pipeline is at least 1.55 atmospheres.

With a centralized supply of water to apartments in multi-storey buildings, residents of the upper floors may experience inconvenience due to low water pressure. For the normal functioning of the washing or dishwasher, which heats the water of a gas water heater, requires a pressure in the plumbing system of two to four atmospheres. At lower pressure this technique will not work. And a weak stream from the tap, or a complete lack of water, is not at all pleasing when you need to wash dishes or take a shower. In order to normalize the water supply situation, residents of high-rise buildings should use pumps to increase the water pressure in the apartment.

Installing a pump in an apartment will only be necessary if the cause of insufficient pressure is not clogged water pipes, but other problems, the solution of which requires a global modernization of the water supply of the entire house.

1 Installation required

Own water pumps in the apartment are installed to create and maintain acceptable operating pressure, taking into account all points of water consumption. When a water resource is used simultaneously in several places, there is a natural decrease in pressure in the overall system.

Normal pressure for an apartment with domestic use water, is considered to be four atmospheres. This is enough to prevent malfunctions in the operation of the washing machine, shower cabin, jacuzzi, geyser, which have automatic shutdown of the device when the pressure is insufficient.

Possible occurrence high blood pressure. An indicator of seven or more atmospheres leads to damage to household appliances and individual elements water supply

With a technically competently designed and properly installed water supply system of an apartment building, situations arise with pressure drops due to peak consumption. For example, in the evening hours, when most residents come home from work and begin doing household chores, water consumption increases sharply. This leads to an offensive situation when lower floors everything is fine, but upstairs it’s difficult to even wash your hands.

A pump for increasing water pressure, mounted directly on the supply line, is capable of providing complete and stable comfort of water use at any level of a multi-storey building.

2 What you should pay attention to?

A water pump installed in an apartment can have two types of control:

• manual - requiring constant monitoring during pump operation;
• automatic - the operation of the device is regulated using special sensors (pressure, pressure, flow).

Installing a manually operated water supply device is advisable if it is not used regularly. And human control is necessary to prevent the pump from running dry. If there is no water in the central water supply, the electric motor will overheat and burn out.

Pumps having automatic control, do not require any attention. They can be turned on constantly, since their operation is regulated automatically, depending on emerging situations.

The temperature of the water in the central water supply is also important, since individual models, increasing pressure can work as follows:

• only with cold water;
• only with hot water;
• both cold and hot (universal device).

An important factor in the operation of the unit maintaining water pressure in the apartment is the method of cooling it:

Air cooling causes increased ambient noise, but the performance of such a device is higher than that of its water-cooled counterpart, which operates almost silently. Used in pipelines for both cold water, and for hot.

2.1 Important Features

Since the water pump will be installed directly in the apartment, some of its characteristics should be taken into account:

• power - the higher it is, the large quantity consumption points will be provided with sufficient pressure;
• noise level - important factor, which should be taken into account to maintain a comfortable noise environment in the apartment. Units that are too noisy are not suitable, especially when working at night;
• the diameter of the pipes brought into the apartment - an increase in pressure is possible only if the cross-section of the pipeline and the pump nozzles fully correspond;
• lifting height - each pumping unit is designed for a certain height of liquid delivery;
• overall dimensions - for an apartment that has limited spatial capabilities for installing this type of equipment, compact units should be selected.

3 Installation in an apartment

Installing a pressure booster pump in your home pipeline will allow you to long term provide all household water needs. In order for the equipment to operate smoothly, you should use the following recommendations:

• the liquid entering the pump must occur through a filter rough cleaning. This prevents solid particles from entering the unit through water, which can cause mechanical damage;
• location only in a dry and heated room, to prevent the corrosive effects of moisture and negative action low temperatures;
• mandatory presence shut-off valve(faucet) installed in front of the pump, which will allow for preventive and renovation work when disconnected from the central system;
• reliable fastening - will ensure the absence of leaks caused by constant vibration of the operating unit.

Installation of equipment capable of increasing water pressure in an apartment occurs as follows:

• the water supply to the apartment is cut off;
• marks are made with a marker on the supporting pipe selected for installing the pump, taking into account the overall dimensions along the length and the presence of adapters;
• the pipe is cut at the marked places;
• on outside the free ends of the pipe are cut into screw threads of the required pitch;
• adapters with internal threads are screwed onto the ends of the pipes;
• adapters are equipped with fittings;
• the pump is installed in compliance with the right direction fluid movement indicated by an arrow on the device body;
• a three-core cable is wired from a household power source;

Upon completion installation work It is necessary to test run the device to check for leaks in the connections. For absolute sealing, it is recommended to use FUM tape, wrapping it around the threaded connection.

4 Models from famous manufacturers

When choosing a water pump for an apartment, you should pay attention to the products of manufacturers who specialize in the manufacture of only such equipment. The most famous companies are Wilo, Grundfos and Jemix. Short description And specifications one model from each of them:

Wilo PB-088 EA is a small-sized model that is installed directly on the pipe. Suitable for use on pipelines with both cold and hot water. Cooling occurs due to the flow of passing liquid. It is equipped with a flow sensor, which turns on the pump when consumption begins (opening the tap at the point of use).

There are two operating modes: with automatic and manual control. Has protection against dry running and overheating. The body is coated with an anti-corrosion compound. Produces little noise during operation.

Specifications:

• maximum head: 9.5 m;
• permissible liquid temperature: from 0 to 60 O C;
• engine power: 0.09 kW;
• capacity: 2.1 cubic meters m per hour;

Grundfos UPA 15-90 - provides increased water pressure when installed on a pipeline inside the apartment. For small overall dimensions and light weight works with liquids different temperatures. Cooling down running water and has protection against dry running and overheating. The body is protected by an anti-corrosion coating. There is practically no noise during operation. Manual control and automatic operating mode.

Specifications:

• maximum head: 8 m;
• permissible liquid temperature: from 2 to 60 O C;
• engine power: 0.12 kW;
• diameter of connecting pipes: 20 mm (¾ inch).

Jemix W15GR-15 A - the device is designed to create and maintain pressure in water supply systems at the optimal level. Two operation control modes - manual and automatic. It is cooled by an air fan, so it is noisy.

Specifications:

• maximum head: 15 m;
• permissible liquid temperature: from 0 to 110 O C;
• engine power: 0.12 kW;
• capacity: 1.5 cubic meters m per hour;
• diameter of connecting pipes: 15 mm (½ inch).

An indicator of the quality of a water supply system, both centralized and autonomous, is the pressure indicator. To measure it, specialized pressure is used (mainly to adjust the pressure when connecting household appliances - a washing machine or dishwasher, boiler, gas hot water supply or as part of a heating system).

Sometimes the pressure is so weak that everything is clear even without the use of instruments. Increasing the pressure in the system when connecting will help correct the situation.

1 Features of use

Pumps for increasing water pressure in an apartment or private house - a special category pumping equipment. Cold water and hot water systems consist of a network of pipelines, the free movement of water through which is determined by the pressure level in the system.

According to standards adopted in Europe, this figure should be from 2.5 to 4 atmospheres, depending on the length of the system and the average daily load on it. The intensity of the pressure also affects the amount and type of equipment used. For example, a pressure of 2.5 atmospheres is sufficient for connection. And for connecting a shower, jacuzzi or heating systems - 3.5-4 atmospheres.

The water pressure in the apartment, as a rule, is 3.5-4 atmospheres. But this does not mean that you will have to give up more comfortable living conditions. An effective and inexpensive solution is pressure-increasing pumps for water in apartments. With the development of multi-storey construction, cases have become more frequent when water does not reach the consumer due to too much long length riser and the pumping station used to complete the pipeline is not capable of raising water to the required level. In this case, an alternative for a pump to the apartment will be.

The same situation applies to suburban and cottage developments. In them, the water supply system is often autonomous, and one pump, even one with increased power, does not always provide the required flow rate. It will not pump water with proper efficiency even if errors were made during the design or installation of the system.

A water pump that increases pressure is also used in industry. These are large-sized backup models that allow you not to stop production processes in the event of an emergency shutdown of the system or a decrease in the water level in the water supply.

2 Device, principle of operation

As a rule, a pressure-increasing water pump, including a domestic pump for an apartment, turns on automatically when a critically low pressure level is detected. They differ in type of design and purpose.

2.1 Types and differences

According to key operational and production parameters, water pressure booster pumps are divided into 2 main categories:

• circulation pumps to increase water pressure in the apartment;
• self-priming pumping stations.

The circulation pump for increasing water pressure is considered the most popular due to its universal simple design. A pump for increasing water pressure of this type is easy to install and provides optimal traffic intensity within the system. It is compact and is intended mainly for adjusting the performance of heating systems and.

The unit consists of a compact motor that drives an equipped rotor. By increasing the rate of water circulation, the pressure in the entire system increases. There are models on the market for both cold water and hot water. Pumps of the first type are cheap due to the use of durable but inexpensive plastic in the production process. They can work in temperature environment, not exceeding +40 o C.

The second type of pumping equipment - stations - is more complex and productive. Key difference from circulation equipment, which cuts into any part of the network and does not affect its autonomy, the pumping station completely cuts off the system from the external source of recharge. However, it is this installation that allows you to increase the water pressure to the required level.

The design consists of a hydraulic accumulator powered surface pump equipped with a self-priming mechanism. Such a unit is guaranteed to improve the quality of water supply even if, for technical reasons, water is by definition unavailable on the upper floors of the building. The pressure level is regulated and maintained at the level specified by the relay adjustment parameters using a membrane-valve system.

2.2 Main characteristics

When choosing a model, we recommend paying attention to the information provided by the manufacturer, since not all units are universal. In general, to select a pump or pumping station, it is enough to pay attention to the following characteristics:

• type of BC system – hot or cold;
• the power of the device, determined by the water intake capacity, the height of the water rise and the maximum value of the pressure increase;
• pressure and flow;
• temperature Range;
• energy consumption parameters;
• productivity (amount of pumped mass per unit of time);
• the direction of the axis along which the working bodies move;
• start type (mechanical or automatic);
• motor cooling method;
• generated noise level;
• material for the production of the body and node connections.

3 Well-known manufacturers

The corresponding market segment is extensive - it presents equipment from both domestic and foreign manufacturers.

The leader is the product, in particular, 15-90/UPA15-90N. The advantages include low weight and size, ease of connection to the pipeline. With a relatively low power, they increase the pressure level by 1.5-2 atmospheres, are made from high-quality durable materials(cast iron and of stainless steel) and create virtually no noise. Both units are equipped with a switch that allows you to adjust the operating parameters using manual or automatic settings.

The German brand Wilo produces pumps equipped with a flow sensor, mainly with a wet type of rotor cooling. Popular models are PB 088-EA, PB-H 089 EA, PB 201-EA and PB 400-EA in cast iron housing. The advantages of this brand's products include:

• easy installation thanks to fastening with nuts;
• thermal protection of the motor;
• low power consumption;
• compactness;
• low noise level;
• corrosion resistance.

Chinese pumps WESTER WPA 15-90/20-120 have proven themselves to be reliable equipment in the affordable segment. They can be used to equip apartments, country houses and cottages. Each of the models works in one of three provided modes in the temperature range +6…+60 o C, has low consumption and raises water to a height of up to 9 m.

4 Connection rules

Installing a pressure booster pump is simple - it can be done without the involvement of specialists. It is most effective to make a cut at the entrance.

Circular pump installation:

• the product is embedded in a single position according to information from the manufacturer;
• When starting work, make sure that the water supply system is turned off and there is no water in it;
• cut the pipe, connect and fix the pump, treat the joints with moisture-resistant and heat-resistant sealant;
• connect the unit to the power supply;
• test the installed pump.

Pumping stations also cut into the system, but this process is best left to specialists. The difficulty of installation is that in addition to inserting and connecting the pump, it is necessary to correctly assemble it and connect the inlet/outlet hoses. Labor-intensive and demanding practical experience is also the process of setting up a pumping station.

Pump to increase water pressure - how to choose the right one?

We offer to buy water pressure booster pumps in a private house in Moscow in a wide range of sizes favorable prices. Using this equipment, you can increase the water pressure in individual segments of the water supply system, ensuring comfortable operation of the water supply network.

Distinctive features of the booster pump

To solve the problem of increasing pressure, two types of devices are used:

• Universal circulation. Their design is intended to maintain the flow of water in a closed system, but they can also be used to increase pressure.
• Specialized household pump to increase pressure - a device whose design is designed specifically to capture the flow into the pump design with minimal hydraulic energy losses and increase the flow speed. Have more high efficiency, and therefore allow you to achieve stable pressure with less energy consumption.

Among technical features These devices can be distinguished:

• Automatic switch on sensor. Convenient and useful solution, which allows you to determine the moment of starting water at points of consumption in order to automatically turn on the device.
• Overheat protection. The thermal relay turns off the device when there is excessive load, preventing failure.
• Protection against operation in the absence of water. The equipment operates only if there is a liquid working medium in the system.

Scope of application of booster pumps

Automatic flow units are used to solve a wide range of problems. Most often, it is necessary to buy a booster pump for water supply:

• To improve the quality of water supply to private houses or individual segments of the water supply system (in case of lack of pressure).
• When constructing networks for watering plants, in order to ensure the required pressure. The simplest and cheapest boosting unit is suitable for this purpose.
• In apartments with unsatisfactory pressure from the centralized water supply network.

Pump selection criteria

Prices for pumps to increase cold water pressure primarily depend on the following factors:

• Device power. Typically from 90 to 270 W. The parameter determines the performance of the unit.
• Maximum productivity, l/min. You need to select based on the parameters of the water supply network.
• Pressure is an indicator of the height to which the device pushes water. Measured in meters.
• Case material. Cast iron and brass structures are used. Cast iron is premium and extremely durable, brass is more affordable.
