Installation of a flow pump. Pump to increase water pressure: calculators for calculating the required pressure for a pump in the house

Often water supply systems have insufficient pressure, which complicates not only the adoption water procedures, but also the operation of auxiliary household appliances. For example, the correct operation of a washing machine or shower may be disrupted. To get out of this situation, you have to use a pump to increase the water pressure. In an apartment or house in such situations, it is indispensable.

Many residents of houses and apartments experience low water pressure

Devices that increase blood pressure plumbing system, are small structures with an engine operating from a conventional electrical network. Installation of the device is carried out by inserting into the pipeline. During operation, torque from the rotor is transferred to the impeller, which creates additional pressure.

All products can be divided according to the control method:

• manual devices are switched by a person during operation for a certain amount of time;
• automatic devices switch independently, as they have a special sensor.

Another classifying feature is the type of cooling;

• models with a wet rotor operate almost silently, as they pass liquid directly through themselves;
• products with a dry rotor create noise during operation, but are more productive.

Note! Before purchasing a pump to increase water pressure in an apartment or residential building, you must also take into account the permissible temperature of the working environment. However, there are also universal devices that operate over a wide range.

Requirements for the device

If the problem associated with insufficient pressure in the water supply system is solved by using a special pump, then you should understand what requirements are placed on it. Basically they come down to this:

• uninterrupted operation;
• optimal working fluid pressure;
• affordable price;
• required performance.

Note! If the water does not reach the upper floors of an apartment or private house at all, then it is recommended to purchase a special station instead of a conventional pump. The necessary pressure is created in them.

Various models of pumps to increase water pressure: prices and manufacturers

High-quality devices that can serve well for many years are produced by trusted manufacturers. In this regard, it is proposed to study the prices of pump models from well-known brands. The following products are popular in the modern market.

Model Wilo PB-088EA

Of all the water pressure booster pumps, Willo PB-088 EA can be considered the most suitable for home use. The device is installed on a pipeline with a working medium of up to 60 degrees. It is low noise, so its operation is quite comfortable. The device can operate in two modes at once - automatic and manual.

The productivity of the device is 2.1 cubic meters. m in one hour. You can buy it in a specialized store for about 3500-4000 rubles.

Model Grundfos 15-90

An alternative option for use at home is the Grundfos 15-90 water pressure booster pump model. Its characteristics are very similar to the above-mentioned products. However, its cost is slightly higher. It reaches 6000 rubles.

Other analogues

The product range is not limited to the models listed above. The table shows products from other manufacturers, the quality of which is beyond doubt.

Note! It is impossible to buy a high-quality pump to increase water pressure for a small amount of money. If the cost of the product is much less minimum amount indicated in the table, it is better to refuse to purchase the product.

How to install a pump to increase water pressure in an apartment or house

It is quite possible to carry out the installation of the device yourself. However, it is still necessary to familiarize yourself with the basic principles of installation in order to avoid catastrophic mistakes. Refusal to involve professional workers will save on installation.

Familiarization with the installation process

When installing a pump to increase water pressure in a house or apartment, a small piece of pipe is cut out at the inlet part of the water supply system. The device itself is connected directly to the two ends. If the pipes are made of plastic, you may need a special soldering iron.

The device must be inserted between the cut pipes

When connecting to a pipeline, you can confuse the direction of water movement through the device, so you should carefully look at the instructions that come with the product to improve the pressure. After installation is completed, the device is connected to the mains.

If the water pressure is normal or even strong, then you simply need this device. You will find out why in our separate review.

Right installed pump will ensure that the home's water needs are met long time if you follow these recommendations:

• It is advisable to protect the installed equipment from blockages by installing a coarse filter at the inlet;
• it is imperative to install in front of the pump shut-off valves so that it is possible to carry out preventive measures;
• the unit must be located in a heated room that is protected from moisture;
• At first, it is necessary to check the device for leaks in order to identify malfunctions in time.

Note! Preferably for safe operation devices that increase pressure in the water supply system, equip a special one, which will be connected through a separate RCD.

Main selection criteria

When purchasing a product to increase pressure in the water supply network, certain points must be taken into account. Typically, six criteria are taken into account.

• Power indicator. The value of this parameter will determine how many consumers can operate the device simultaneously.
• The level of noise generated during operation. Models can operate loudly or very quietly. This primarily affects the comfort of use.
• Possible height of water rise. Some devices may not reach the working environment directly to the required level.
• Device dimensions. From sizes specific model The possibility of placement in a certain room will depend.
• Section of connected pipes. If this criterion is not taken into account, problems may arise during installation.
• Manufacturer's fame. Mostly, high-quality products are produced by companies that are highly popular in the market.

Summarizing

With the advent of pumps to increase water pressure in apartments and separately standing houses deficiencies in plumbing systems can be completely eliminated. Such devices are accessible from an economic point of view to a wide range of consumers, and therefore are in demand. In some cases, it is better to purchase a device to improve pressure yourself rather than solve the problem with specialized services.

Pumping station for a private house: water supply, types and installation features

If there is running water in your home, then water should also come from the tap. However, this, unfortunately, does not always happen. Sometimes the pressure is so weak that water does not flow from the tap, and home appliances do not want to act in such circumstances. Residents on the top floor of high-rise buildings often cannot see the water at all. It is for such cases that pumps are produced to increase pressure.

Causes of low blood pressure

Before purchasing a pump, a certain specification of the issue is required. Frequent questions are:

1. What to do if water is flowing, but there is actually no pressure?
2. What to do if water does not flow only to the top floor of the home; it is on the lower floors.

In the first case, the issue can be corrected by installing a pressure increase pump. The second problem cannot be corrected by a similar method, therefore, the solution is a pumping station, the purchase of which will need to be spent. The selection process is very complex and depends not only on the need for water, but also on some other components.

The problem is that before buying a pump you need to make sure that the source of absolutely all troubles is actually is low blood pressure, not clogged pipes . Because various deposits over time can significantly reduce their diameter, therefore, in this situation, even the pump may be powerless, since a change in the water supply will be required. If the issue is still low pressure, then a pressure pump will come in handy.

How to achieve perfect pressure in water pipes?

According to standards, the water pressure in the apartment should be 4 atmospheres however, differences can usually vary greatly. A coefficient of more than 6-7 negatively affects plumbing, leads to breaking of pipe joints, and low values ​​are not favorable. If the pressure is less than 2 atmospheres, in this case the washing machine, dishwasher and flow-through heater for supply hot water, disruptions threaten.

The following values ​​are used as units for measuring pressure in pipes: 1 bar = 1.0197 atmospheres = 10.19 m of water column. The minimum pressure required for the operation of many home devices ranges from 1.5 to 2.4 atmospheres; in fire extinguishing systems the requirements are higher - at least 3 atmospheres.

In case the indicators in the system are significantly lower, for example, because the apartment is on the final floor of the building, or because of the large amount of water used, in this case there is a need to use specialized means(installations) that would maintain the required pressure level. In any case, the problem should be detailed first.

Please note when selecting a device: what parameters is required for the unit?- to increase weak pressure or to raise water from the lower floor to the upper one. The main option involves equipment that is small in power and size. It is simply defined in the pipeline. For the 2nd option, you will need a centrifugal apparatus with a hydraulic accumulator. Both perform work in 1 of 2 modes: The continuity of operation of the equipment is determined by the manual mode.

In order for the device to work for for long years, it is necessary to prevent it from overheating Therefore, it is necessary to turn off the automatic mode in a timely manner. In this case, the flow regulator implements control. If the truck tap opens and water starts flowing, the pump turns on. This order is the most advantageous, since the pump does not turn on when there is no water, and, therefore, is protected from dry operation, which leads to the longest service life of the device. It is also customary to systematize pumping units according to the housing cooling method. It is executed in 2 ways:

• using an impeller;
• thanks to water pumping.

If a reason has been determined low pressure, and it consists in the fact that the water simply does not rise to your floor, you need to purchase the most powerful device - a self-priming pumping station. Installation of the pump, which can be purchased, is carried out with or without a hydraulic accumulator. Numerous residents choose the second option, although experts insist on the first, even if the modification has a small tank.

What is a pressure boosting pumping station?

This is a simplified centrifugal device for improving water pressure; it operates with an attached hydraulic accumulator and a pressure switch, which has the function of controlling the entire system. With the support of such a system, water is collected and supplied to the tank. Even if the pressure switch turns off the pump, the consumer still has the opportunity to drink prepared water, which is comfortable in case of frequent shutdowns. The pressure will decrease. As soon as it drops to the set mark, the relay will work again and the pump will turn on. You can understand that the larger the tank, the less the load, the longer its operating period.

What to consider when choosing a unit for an apartment

Selecting equipment There are several important points to take into account:

Without knowing the required performance and pressure, it is very difficult to make the right choice. It is better to entrust all necessary calculations to a professional. Numerous companies that sell such equipment provide this service absolutely free.

If you just need to slightly increase the pressure in the system by approximately 1.5 atmospheres, in this case small pump, which you can simply buy and cut into a pipe, will fit perfectly. Some experts consider the expensive and powerful pump design to be unnecessary. In their opinion, the most rational option is a pair of devices of lower power that are connected directly in front of the disassembly points and home devices, the operation of which needs to be optimized.

Today, purchasing pumping equipment to increase water pressure is not difficult. Since it is freely presented in different shopping centers household appliances, online stores, construction markets. However the best solution There will be a visit to the company salon, where there is the most extensive selection, and there is the opportunity to receive information from a professional. After that, you will be provided with warranty service, which is especially important if the consumer purchases an expensive model.

How to install an automatic water pressure booster pump with a hydraulic accumulator?

Installing a pump with a hydraulic accumulator is not particularly difficult. This will require approximately the same skills and equipment that are needed to install other types of pumping equipment. Schematically The design of a booster pump can be presented in the form of the following steps:

Basically, a pump and hydraulic accumulator with a pressure switch involves a variation of the station. To implement the design of such a system of devices, it is first necessary to find a position for placing the tank. Certain craftsmen replace a hydraulic accumulator with a large-capacity membrane, for example, plastic tank 200 liters. Instead of a relay, the tank is equipped with a float meter to ensure that it is automatically filled according to demand. This type of tank is located as high as possible: in the attic or on the top floor.

You immediately need to think not only about volumes, but also about the configuration of the container. A flat and small tank will take less space than the classic tubular model. Although there are no specialized conditions for the configuration of the container. When choosing the position for the tank, it is necessary to calculate access to the tank/hydraulic accumulator or the likelihood of simply dismantling this component. This is necessary for execution technological services, repair work or changing the device.

Hydraulic accumulators are delivered ready for installation, but the tank needs to be prepared. There are holes in it for the flow and intake of water. You can also make your own shut-off valve to pour water into emergency situation. The water supply pipes to the tank and its intake into the water supply system are installed to one pipe.

In modern circumstances, it is more logical to use easy-to-install and durable plastic pipes for installing water supply systems. To prevent air from being sucked into the reservoir from the pump, and also to avoid water entering there when the equipment is turned off, Opposite valves must be installed on both pipes. Subsequently, pipes are installed, with the support of which the tank is connected to the water supply system.

After the reservoir or accumulator is installed and the required installation is done water pipes, you can start installing a suction pump. As a rule, such a device is supplied disassembled. It is first assembled, and then installation begins. If you decide to fix the pump in the wall, you must first make markings for the fasteners. Then it is suspended and connected to the water supply. Overall, this is not a very complicated procedure.

An important point is the direction of water in the device. It is marked in the case with special marks. The pump must be installed in such a way that water moves from the tank to the water collection points. Similarly, the pump installation and switching diagram looks like this: hydraulic accumulator - pump - consumer. Then the pump is strengthened. All connections should be carefully sealed. After this, it is necessary to check the operation of the entire system.

Which is better?

The water pressure pump market is wide and diverse. It presents a huge number of products from manufacturers from various countries. The following modifications are better known:

Sprut 15WBX-8

Household silent pump is a pressure booster unit, offered at an affordable price, designed for installation in an apartment. Has the following data:

• cooling method - dry rotor;
• the operating procedure is automated;
• lowest inlet pressure 0.3 bar;
• working pressure, no more than 6 bar;
• productivity no more than 0.09 kW;
• efficiency is not less than 8 l/m;
• the largest weight is 2.24 kilograms.

Aquatica 774715

Domestic automatic pump designed for use as a pressure increasing unit in a private home and has an affordable price. Recommended for the purpose of maintaining the pressure required to ensure working capacity geysers, washing and dishwashers. Characteristics:

You can purchase a high-quality pump to increase water pressure in building materials markets, special outlets selling plumbing fixtures, and, in addition, with the support of functioning stores on the Internet. Wherever pumps for increasing water pressure are sold, a potential consumer can familiarize himself with the operating parameters and obtain qualified advice on absolutely all issues of interest to him.

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

The boost pump will become optimal solution for the local level. It is installed within the apartment and is designed to serve one household. The installation of such equipment will be effective if the problem lies solely in insufficient pressure, but 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 optimal value is 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, which require at least 2 atm, may not even start. You can only take a shower in the shower stall at 3 atm. Approximately 2-2.5 atm is required to start the boiler. The Jacuzzi will be in working condition at 3-4 atm.

Operational parameters of connected equipment

Before connecting, you need to understand what characteristics booster water pumps have. They differ in the way they start:

• User launch option. The hydraulic device 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 rapid failure from overheating. Often a feature of the operation of such circuits is one-time operations followed by 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 the flow certain temperature. Design features manifest themselves in the ability to pass water in a limited temperature regime. In specialized retail outlets or on online store websites you can find the following types of devices:

• units capable of working exclusively with cold systems;
• models designed for inclusion in hot flow distribution;
• universal equipment designed to interface with any liquid temperature.

A high-quality pump, which should not overheat significantly during operation, helps maintain a stable pressure level.

Cooling systems help get rid of overheating.

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

• The temperature decreases due to the flow passing through the housing. This technique called the “wet rotor” method. It has minimal noise parameters, but can overheat when operating without water.

• For cooling, rotating blades fixed on a shaft are used. The method is called a “dry rotor”. The disadvantage is increased noise during operation. The disadvantages are compensated by the fairly high degree of performance that the water pressure pump has.

Implementation of boost stations

For apartment owners on the upper levels, it is advisable to install a pumping station. Self-priming technology includes the following elements in the circuit:

• hydraulic pump;
• pressure gauge;
• relay;
• hydraulic accumulator.

The principle of operation of the unit is to pre-fill the hydraulic accumulator, independently set the desired output pressure using a relay and start the pump, which ensures the distribution of liquid to consumers.

Some schemes propose eliminating the hydraulic accumulator; however, this approach will negatively affect the service life 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 pumping system less often.

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

Before purchasing a station, it is recommended to check its maximum pressure. You can use the popular Grundfos JP Booster 6-24L model, which provides a head of 48 m and has a large 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 a suitable pressure booster pump, there are important factors to consider:

• Power characteristics. The more productive the unit is, the wider the number of points it can effectively serve. In the calculations, it is necessary to monitor the number of consumers, washing machines and plumbing fixtures.
• Noisy. Of course, less noisy devices are preferable, but they may be more expensive.
• 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 instructions. Failure to comply with this parameter can lead to work with overloads, breakdowns and a decrease in pressure below the calculated value.

Electrical device design

• Lifting height. When purchasing a pumping station with a lower load, it may not reach the required level.
• Equipment dimensions. The hydraulic unit 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, which should not be less than 4 barrels. Next, they are determined directly with the characteristics of the electrical appliance - dimensions, noise level when turned on, wet or dry, etc. Because the we're talking about about the pump high pressure, for many it will be a fundamental point - manual or automatic control.

Pump equipment for hot water supply differs from that installed in a cold water system.

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

Among the priority companies:

WILO- leader in consumer demand according to reviews and store statistics. Considered elementary in management, has worked for more than 7 years in extreme conditions and very reliable in operation.

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

OASIS- easy to operate, quality equipment, which is still 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 quiet. The installation pipes are standardized for Russian water utility systems.

Connection diagram - right and wrong

Water pressure pumps on collectors operate non-stop. In order for the pressure to increase gradually (stepwise), a multi-wheel system is used. During operation, the device is capable of creating a pressure in the system of up to 10 bar.

The best pump models for increasing water pressure

In order not to be mistaken with the desired result, choose well-known trade marks: Wilo, Grundfos or Jemix. They are widely represented in online internet stores and in traditional construction supermarkets.

A common problem in apartment buildings or private buildings is a sharp decrease in water pressure. During such surges, the equipment turns off, and sometimes the water pressure is not enough even for minimal comfort, not to mention watering, washing, etc. To eliminate this risk, it is recommended to install a special pump to increase the water pressure. Let's consider the best offers from manufacturers so that the chosen option turns out to be the most optimal.

Types of pumps

The entire range of pumps for increasing water pressure is divided into two main types - with a wet and dry rotor.

With wet rotor

Used in heating systems ah with a short pipeline length. The design includes a rotor with an impeller, which accelerates the circulation of water at speed. The liquid in which the rotor element makes movements cools and lubricates the functioning mechanisms.

When installing such a pressure pump for water supply, it is necessary to take into account the horizontality of the shaft, its service life depends on this. The advantages of equipment with a wet rotor are minimal noise, stepless speed control, reliability, durability and maintainability. Separately, users note the lack of need for maintenance And affordable price. The disadvantage of the devices is low efficiency - up to 50%.

With dry rotor

This technique is used for heating systems with a long pipeline length. Between the electric motor and the main operating area of ​​the rotor are O-rings that can last for more than three years. Due to the design features, the rotor itself does not come into contact with the liquid. Plus dry pumps for increasing water pressure in a private house in high efficiency- up to 80%.

Dry rotor device

The second, no less significant disadvantage is that there is a lot of noise during operation, so it must be installed in separate room where there is good sound insulation. In addition, constant monitoring is required to ensure that there are no large solid particles in the water and that dust does not accumulate in the power unit. Otherwise, the tightness will be broken due to damage to the sealing rings and the device will fail.

The best pumps for increasing water pressure with a wet rotor

The specificity of the design of “wet” circulation units is that the impeller is located in the liquid, which they pump. On the one hand, this liquid cools the engine, on the other, it lubricates it. Regardless of the material of the rotor shaft - ceramics or metal, they all have high class protection from damage and operate with minimal noise levels.

Grundfos UPA 15 90

The Danish device Grundfos UPA 15-90 N is equipped with a cast-iron stainless steel body, an asynchronous type motor, a flow controller, and a terminal box. The stator and rotor are separated by a sleeve. During installation, the shaft is mounted in a horizontal position.

Grundfos UPA 15 90

The Grundfos pump for increasing pressure operates at an automated level or in manual mode. Up to 1.5 m3 of liquid is supplied per hour, and the pressure is 8 m. Working temperature varies from +2°C to +60°C. The minimum outlet pressure is 0.2 Bar.

The working roller here consists of a composite, the shaft and bearings are made of aluminum, and the protective sleeve is made of stainless steel. The compact device has a length of 160 mm and weighs up to 2.6 kg.

Separately, it is worth highlighting the presence of protection against overheating and idle move. For 5500-7000 rubles the consumer will receive a compact booster pump High Quality assembly and with a simple installation system. In addition, the product comes with a 3-year warranty. The downside of the device is the expensive after-warranty repairs.

Wilo PB-201EA

Best Dry Rotor Pumps for Boosting Water Pressure

In “dry” type devices, the engine does not come into direct contact with the liquid. On the one hand, this increases the efficiency by almost 2 times, on the other hand, the operation of the electrical appliance is very noisy, which precludes its use in the house itself, and on the third, which is very important, the temperature range of the working fluid expands. Even at +80°C it can work for a long time.

Jemix W15GR15-A

The domestic-Chinese model is equipped with a housing made of durable cast iron, as well as a plastic rotary roller and a motor with an aluminum outer part. With the help of a regulator on the terminal box and a flow level controller, the equipment operates in forced or automated mode. Electrical engine has no contact with the pumped water, so the air type is used as the cooling system.

The device is installed in a horizontal position and fixed to the wall. The main characteristics of the model are the following parameters:

• flow - 1.5 m3/h;
• head - 15 m;
• autostart at 0.09/0.12 m3/h.

The device is highly resistant to corrosion. The equipment weighs 3 kg, which simplifies the installation process, and it also has small sizes 220x170x130 mm. The device costs up to 3,500 rubles.

Users noted that this option has a fairly short electrical cable. You need to extend it yourself. Excessive noise was also noticed.

How to choose the best pump model in 2018

The most important indicator The water pressure booster pump is its power. There is no need to select a model with maximum indicator, this can lead to breakdown of the plumbing system, and a lowered parameter will also not be beneficial. Therefore, it is necessary to choose a device with the most optimal indicator. The liquid pressure should not exceed 2 Atm; this will be enough for comfortable water procedures and operation of an automatic washing machine.

But you need to take into account that if the cottage has a jacuzzi, shower and similar devices, the pressure should be slightly higher - up to 5-6 atm. Therefore, before purchasing a booster pump, you should first calculate the required pressure level based on the instructions for household appliances. Also consider the likelihood of purchasing new equipment.

A specialist will help you make the most accurate calculations, but, as a rule, an approximate calculation is sufficient. To calculate the fluid pressure in the system, prepare liter jar. It needs to be placed under the tap and the mixer turned on to maximum. At the moment of water supply, you should note the time and then calculate how many liters come out in one minute.

Next, you need to decide on your household needs. For example, for a shower, low pressure is sufficient; a traditional pump with an increase capability of up to 2 Atm is suitable here. But, if the house has a washing machine, dishwasher, car wash and other equipment, study its technical documentation, and then determine the maximum indicator.
