The benefits of any apartment buildings are efficient communication systems, which include plumbing. The quality of its functioning depends on the work household appliances, for example, a boiler, washing machine or dishwasher. 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 being introduced into the home hydraulic system often on the upper floors. There often established norm 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 invalid, since in this situation automatic washing machines, which require at least 2 atm. 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 understand what 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, it is worth paying attention to the ability to transport the flow certain temperature. Design features manifest themselves 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 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 to this 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 management, has been working for more than 7 years in extreme conditions and 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 manage, quality equipment, which so far only aspires to the TOP-10, but has not yet approached.
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.

An indicator of the quality of the 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 - washing or dishwasher, boiler, gas hot water or as part of a heating system).
Sometimes the pressure is so weak that even without the use of instruments everything is clear. To correct the situation will help increase the pressure in the system when connected.
Features of use
Pumps for increasing water pressure in an apartment or a private house are a special category of 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 level of pressure in the system.
According to the standards adopted in Europe, this indicator 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 number and type of equipment used. For example, a pressure of 2.5 atmospheres is sufficient to connect. And to connect a shower cabin, 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 more comfortable living conditions will have to be abandoned. An effective and inexpensive solution is pressure boosting pumps for water in apartments. With the development of multi-storey construction, cases have become more frequent when water does not flow to the consumer due to the length of the riser being too long and the pumping station used in the pipeline configuration is not able to raise water to required level. In this case, an alternative for the pump to the apartment will be.
The same situation is in suburban and cottage buildings. In them, the water supply system is often autonomous, and one, even characterized by increased power, the pump does not always provide the proper flow rate. It will not pump water with due efficiency even if mistakes 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-type models that allow you not to stop production processes when emergency shutdown system or lowering the water level in the water supply.
Device, principle of operation
As a rule, a pressure-boosting water pump, including a household one for an apartment, turns on automatically when a critically low pressure level is fixed. They differ in type of construction and purpose.
Types and differences
According to key operational and production parameters, the water pressure booster pump is divided into 2 main categories:
- circulation pumps to increase the water pressure in the apartment;
- pumping stations self-priming type.
Due to the universal simple design, the circulation pump for increasing the water pressure is considered the most popular, the pump for increasing the water pressure of this type is easy to install and provides optimal indicators of the intensity of movement within the system. It is compact and intended mainly for adjusting the performance of heating systems and.
The unit consists of a compact motor that drives an equipped rotor. By forcing the water circulation rate, the pressure rises in the entire system. 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 a temperature environment not exceeding +40 ° C.
The second type of pumping equipment - stations - is more complex and productive. The key difference from the circulation equipment, which crashes into any fragment of the network and does not affect its autonomy, the pumping station completely cuts off the system from external source make-up. However, it is this installation that allows you to increase the water pressure to the required level.
The design consists of a hydraulic accumulator 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 not available on the upper floors of the building. The pressure level is regulated and maintained at the level set by the adjustment parameters of the relay using a membrane-valve system.
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 aircraft system - hot or cold;
- the power of the device, determined by the water intake capacity, the height of the water rise and maximum value 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 nodal connections.
Notable Manufacturers
The corresponding market segment is extensive - it presents equipment from both domestic and foreign manufacturers.
The leader is products, 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 stainless steel, respectively) and practically do not create 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. The benefits of this brand include:
- easy installation due to fastening with nuts;
- thermal protection of the motor;
- small power consumption;
- compactness;
- low noise level;
- corrosion resistance.
Chinese pumps WESTER WPA 15-90/20-120 have proven to be reliable equipment in the affordable segment. You can use them in equipping apartments, country houses and cottages. Each of the models operates in one of the three provided modes in the temperature range of +6 ... +60 ° C, has a small consumption and raises water to a height of up to 9 m.
Connection rules
Installing a pressure booster pump is simple - you can handle it without the involvement of specialists. It is most effective to perform a cut at the entrance.
Circular pump installation:
- the product crashes in a single position according to information from the manufacturer;
- when starting work, make sure that the water supply system is turned off, there is no water in it;
- cut the pipes, connect and fix the pump, treat the joints with a moisture-resistant and heat-resistant sealant;
- connect the unit to the mains;
- test the installed pump.
Pumping stations also crash into the system, but this process is best left to specialists. The complexity of the installation lies in the fact that in addition to tapping and connecting the pump, it must be correctly assembled and the inlet / outlet hoses connected. Labor intensive and demanding practical experience is the process of setting up a pumping station.
Installation in an apartment of a pump that increases water pressure GPD 15-9A (video)
A pump to increase the water pressure in the water supply is purchased to stabilize the pressure in the system. Indeed, for the simultaneous operation of several points of consumption, for example, two taps, the pressure in the system must reach 1.5 atmospheres. A washing machine or dishwasher will only work at a pressure of 2 atmospheres (and no less). And jacuzzis and showers with a hydromassage function “start” at a pressure of at least 4 atmospheres.
At the same time, in domestic water supply there is often no minimum pressure (1.5 atmospheres), not to mention the standard indicators (4-4.5 atmospheres). As a result, installing a water pressure booster pump is the only way to provide any acceptable living conditions in the house. Indeed, without this pump, neither the shower cabin nor the washing machine will function.
And in this article, we will discuss the choice of devices used to stabilize the pressure in domestic water pipes at an acceptable level.
Firstly, if there is water only on the lower floors of the house. Secondly, if you open one tap, it is no longer possible to use the second source of consumption. And, thirdly, if the system has a frankly weak pressure, which is not enough to service household or plumbing fixtures

In a word, both a conventional pump and a powerful self-priming pumping station are used if there is no stable pressure in your water supply. Moreover, problems with plumbing will certainly affect the overall level of comfort, reducing the very “quality of life”.
Therefore, you will have to buy a pressure pump or pumping station:
- Firstly, it is quite powerful, but no frills: after all, an increase in pressure to 6-7 atmospheres can destroy the internal elements (seals, valves, and so on) of shut-off and control valves.
- Secondly, it is relatively cheap: after all, money needs to be spent “wisely”.
- And, thirdly, it is compact and quiet: after all, the immodest dimensions of the unit will spoil the entire interior of the home, and noise pollution will disrupt the comfort of living.
But both a conventional pump and a pumping station fit these criteria. What's better? Let's figure it out.
Domestic water pressure booster pumps
Such devices are installed in internal plumbing houses or apartments. Therefore, pumps should not be large and noisy.
Moreover, there are two schemes for operating such equipment:
- A permanent option, assuming almost round-the-clock operation of the device.
- Automatic option, including the unit "on demand".
In the first case, we only need a pump, and in the second, we will have to add a flow sensor to it, which, of course, will affect the price of the equipment.
But the more expensive automatic option is still more profitable than the cheaper permanent one. We will explain why: during operation, the pump heats up and fails due to overheating. Therefore, continuous operation of such equipment is strictly contraindicated.
And the automatic pump, which works from time to time, turns on only when the flow is provoked by water consumption (an open tap, turned on washing machine and so on). Therefore, it will never burn out. And such a pump consumes much less electricity.
As a result, any prudent homeowner will choose the automatic option, despite the slightly inflated cost. And permanent pumps are good only in one case - if they will be used in one-time operations. Suppose, if necessary, to stabilize the pressure after activating the irrigation system. In this case, the pump is simply “plugged in” and turned off after the procedure is completed.
Pumping stations
In fact, this is the same high-pressure vibration or centrifugal water pump with a hydraulic accumulator or hydraulic tank. However, unlike pumps, stations are mounted between a water source and a water supply. As a result, it is the pumping station that generates the pressure in the water supply system.
Moreover, almost all systems are equipped with similar installations. autonomous water supply. And in order to stabilize the pressure in the system, it is necessary either to replace the existing station with a more powerful one, or to replace only the pump or station accumulator with a more productive analogue.
In addition, to increase the pressure in the pipeline, you can even change nothing! It is enough to simply adjust the operation of the pressure switch. The essence of this solution lies in the fact that a special device is “responsible” for the pressure of the station - a pressure switch that monitors the operation of the pump and accumulator.
Let us explain in more detail: the pump pumps water into the drive, which gives it to the water supply. In this case, the pump does not work constantly, but only when the pressure in the accumulator is less than the minimum. Then it turns on, pumping water until the pressure in the accumulator rises to the maximum possible.
The maximum and minimum pressure in the accumulator is determined by a special relay. Increase the time the lower pressure limit in the accumulator, and it will increase in the entire water supply.
How to choose a pump?
The selection of a high pressure pump is based on the following rules:
- Firstly, the pump must work as long as necessary, without pauses and long breaks, without overheating and without shutting down. Therefore, you need a unit from a trusted company with a good reputation, and not a Chinese-made clone.
- Secondly, the pump must increase the pressure in the system to an acceptable level of 4-5 atmospheres, and no more. Therefore, the purchase of a heavy duty station for deep wells not always justified. And if you cannot calculate the required performance of the unit yourself, contact the specialists. In specialized stores, this service is offered to all pump buyers absolutely free of charge.
- Thirdly, the pump must fit the budget of the purchase. good equipment is not cheap. But it pays for itself through trouble-free operation. Cheap pumps require frequent maintenance and practically self repair. After all service centers no-name manufacturers simply do not. Therefore, if you do not have plumbing and plumbing skills or do not have time for such work, buy reliable unit from a trusted brand, such as the wilo water booster pump. This technique will pay for itself 100 percent.
As you can see, the selection rules are very simple. But if you have doubts about your decisions, contact the experts.
Most specialized companies offer a turnkey solution to the problem of insufficient pressure. That is, with the call of the master for diagnostics, calculation and selection of equipment and the subsequent installation of all units in the water supply system.
Pressure Boosting Pumps water in the water supply system are household pumps. They are very much in demand at the moment. Often, due to low water pressure, various Appliances or simply with difficulty you can take a shower or take a bath. What can I say about such an important matter as washing dishes.
This device is real solution water pressure problems in a city apartment or in a private house - it increases the water pressure in the system to right level and stabilize it.
The presence of a pump that increases the water pressure in the apartment is a great advantage, because household appliances such as geyser, dishwasher, washing machine work without failures and breakdowns only if there is a stable water pressure.

Usually not all residents apartment building satisfied with the quality of the water supply system. It's all about the pressure of water, which can sometimes be so weak that it is simply not enough for the functioning of household appliances (washing machine, dishwasher, gas column). Sometimes, with a weak pressure in the water supply system, the water does not reach the inhabitants of the upper floors at all. If the total pressure in water networks we can’t influence, then you can still do something for your apartment. To obtain a comfortable water supply within your apartment, it is enough to buy and install a booster pump. Such equipment will only help if trouble bad pressure not related to downtrodden water pipes or inlet riser.
To increase the water pressure in the plumbing system, special pumping equipment is used. If for an apartment building the pressure rate should be within 4 bar, then in fact it can drop to 1.5 bar. At the same time, for the operation of many household appliances, the water pressure in the water supply system of the house and apartment must be at least 2 bar. And the shower and jacuzzi will not be able to function at all at such a pressure, since they are designed to work at a pressure of at least 4 bar. At the same time more high pressure may not have the best effect on the plumbing of the house.
Important: some details plumbing system in the house can be damaged if the pressure rises to 7 bar or more. That is why it should be within the normal range and be stable.
As for the peak hours of water consumption, residents of the upper floors of the house are especially affected here, who may not even wait for water from the tap. At the same time, a normal water supply is provided to the apartments on the lower floors. To increase the pressure of the liquid in the water supply system on the upper floors, you will need to buy and install a pumping unit to increase the pressure. Their installation is carried out in the inlet part of the water main.
Varieties
All pump products for increasing pressure may differ in the following ways:
- Depending on the control features, the units are distinguished:
- With manual control. Such a household pump can always be either on or off. The owners of the apartment only need to ensure that there is water in the system. If the unit runs “dry”, then it will quickly fail from overheating. It would be most reasonable to turn on the device when using the water supply and turn it off when this is completed;
- the automatic water pump is equipped with a sensor that turns on the unit when it is needed. The same device turns off the automatic pump when there is no water in the pipes.
- Depending on the temperature of the working medium, pressure boosting pumps are divided into the following types:
- pumping equipment designed to work only in cold water;
- units for increasing the pressure in pipes with hot water;
- universal automatic device designed to work in conditions of any ambient temperature.
- To protect pumping equipment from overheating, one of two cooling systems must be used:
- wet rotor units are cooled by the pumped water. These devices for increasing the pressure in the water supply system of the apartment are distinguished by quiet, silent operation. But they can quickly overheat and fail in the event of a “dry run” (when there is no water in the pipes);
- devices with a "dry rotor" for cooling use the air flow, which is created by the rotation of the blades mounted on the shaft. These products make more noise during operation, but their performance is much higher. In addition, their performance does not depend on the presence of water in the system.
Self-priming pumping unit
As for the apartments on the upper floors of the house, where water sometimes does not reach at all, then the only way out is to use a self-priming pumping station. The standard station includes:
- pump equipment;
- pressure switch;
- hydraulic accumulator (membrane tank).
Such pumping unit pumps liquid into the hydraulic tank. The desired pressure indicator is set on the relay. Then the unit supplies water to consumers from the tank under a certain pressure.
Tip: there are pumping stations without a hydraulic tank, but for a home it is better to buy equipment with a hydraulic accumulator, in which the necessary supply of water will accumulate. Thanks to this, pumping equipment will turn on less often and last much longer.
Such a pumping unit works according to the following principle:
- First, the booster pump will draw water into the hydraulic tank. After that, it will turn off.
- At the same time, the consumer can use water from the membrane tank even when there is no water in the pipes of the house.
- After all the water from the hydraulic tank has been used, the pump will start again to pump water into the storage tank.
A pumping unit for increasing water pressure can be used not only in an apartment, but also in a country house, in country house for the arrangement of the water supply system and watering the garden.
Before purchasing a station, it is necessary to clarify its maximum pressure. For an apartment, you can use low-power units. And for country house you will need equipment with a significant pressure.
How to choose?
When buying a pressure booster pump, you need to pay attention to the following specifications:
- The choice of power of the device should be done taking into account the number of taps in the apartment, as well as household appliances installed and connected to the water supply.
- The noise level is very important for any apartment, so give preference to silent appliances.
- Each booster pump is designed for a specific section of the pipeline. If you choose an inappropriate unit, then it can work with overloads or give insufficient pressure.
- Any pumping unit provides a certain level of water rise. A unit with an insufficient lift level will not be able to supply water to the desired point in the house.
- The device is mounted on the inlet water main, which is usually located in the toilet or bathroom. Due to the fact that they do not differ in impressive size in modern apartments, pumping equipment should be compact in size to save space in the house.
Installation of equipment
The installation of a water pressure booster pump in a water supply pipeline is carried out in the following sequence:
- The supply main pipeline to which the booster pump will be attached must be marked taking into account the dimensions of the unit and adapters.
- The water supply to the apartment is blocked.
- The pipeline is cut along the markup in two places.
- Threads are cut at the ends of the pipe.
- Then, adapters with an internal threaded connection are screwed onto the threaded pipeline.
- After that, the fittings from the set of pumping equipment are screwed into the installed adapters. In this case, pay attention to the arrows on the device. They will indicate the direction of the fluid and help you install the pump correctly.
- A three-wire power cable is run from the electrical panel to the pumping product. It is better that there is a separate outlet near the pump, and the device is connected through an RCD.
- After assembling the system, the pump can be turned on and checked for proper operation. Special attention it is worth paying attention to the absence of leaks in the places where the fittings are installed. If required, the fasteners can be tightened. For better sealing all connections, use linen tow or FUM tape.
When installing a pressure booster pump, the following recommendations must be observed:
- In order for the pumping equipment to last as long as possible, use a filter device that must be installed on the inlet pipe of the unit. This will protect the product from debris and other small particles that can cause rapid wear of the mechanical parts of the pump.
- A dry, heated room is suitable for installing the equipment. If the product will work with sub-zero temperatures the water will freeze and the unit will fail.
- Since vibration is observed during operation of the unit, over time it can cause loosening of fasteners and leakage. Therefore, periodically it is necessary to check the tightness and tighten all connections.
