Grundfos circulation pump with dry rotor. Selection of circulating pumps and their characteristics for a private house heating system

Winter every year becomes warmer and less predictable. The absolute record was recorded in the 2017-2018 season. Specialists - meteorologists from the FSBI "Institute of Global Climate and Ecology" fixed abnormally warm values \u200b\u200bof temperature for winter and spring for a variety of regions of Russia. "Well, at least to save gas," they will say one. Others vulnerable. - Predicting the weather is an ungrateful thing, and for real savings you need other measures. - And they will be right.

Strictly speaking, modern technologies have long allowed to effectively insulate any dwelling. In addition to comfort, it is a significant savings of heat and energy resources. But besides the external and internal thermal insulation of your home, you should not forget about the heating system. Even if it is properly designed and does not cause complaints, it can always be made more economical.

Here it is necessary to make a reservation. There are different types and sizes, and they can be heated in different ways. In small areas of buildings, a system with natural circulation of the coolant is most often used. Pure physics and nothing more. Heated B. gas boiler Water rises upstairs, and already spent and cooled, descends under the action of gravity. But such a system is unlikely to be effective for medium and large buildings. The circulation of water in the system is slowly, and therefore problems with heating radiators are possible, and even at all, there is a risk of pipe freezing in unheated places.

Alternative to natural, in this case, the forced circulation of water becomes. In this case, pumps are used, which are mounted in heating systems. Namely, in the inverse tube (the so-called "return") which comes from radiators to your boiler. Forced circulation ensures constant and uniform impact of heat in all rooms at home.

In order not to make a mistake when choosing a pump for your heating system, you need to know many parameters. But the main one of them are: how much thermal energy is needed, and what are the indicators of hydraulic resistance? For an ordinary person, all this is difficult. And in order not to make a mistake, it is better to trust the professionals that will select optimal model equipment.

In Russia, a rather large selection of pumps, both with "wet" and "dry" rotor. However, not all of them apply to engineering systems private houses. Pumps with a "dry" rotor have a large efficiency (up to 80%), but are very noisy. As for the aggregates with a "wet" rotor, then they are the opposite: very compact, mounted in any heating systems, almost silent, and therefore are so loved by the owners of private houses. "Wet" pumps are called due to the fact that the rotor is in water and cool it there. The liquid plays the role of lubrication for the mechanism. The device is mounted in the horizontal position of the shaft so that water is constantly in the housing.

Grundfos pumps

Being an unconditional technological leader in the pumping equipment market, Grundfos (Russia) is pleased to offer its customers a large selection of models. The assortment has both adjustable and unregulated pumps. This, for example, a compact UPS with a "wet" rotor and an asynchronous engine, which has three speed control modes. Switching occurs manually using a special lever on the housing. In case, due to the long idle, the zakus rotor, the pump shaft can be scrolled manually.

As for regulated pumps, here Grundfos offers a whole family of Alpha series devices. Each of them, with proper operation, will last for many years and will not deliver unnecessary trouble. These models according to the degree of increasing functionality can be positioned as follows: and alpha3.

This series of pumps are wider than the UPS. They implemented the possibility of automatic adjustment of the rotational speed of the shaft, which allows the use of heating systems with a high degree of automation as part of heating systems. Like all GRUNDFOS circulation pumps, Alpha1 L differs in very high energy efficiency, the EEI coefficient is less than 0.23. This means a very high efficiency. "L" in the index means limited functionality. Take a look at the list of pump features - it is more than impressive, only 6 modes are provided. But Grundfos is not known for a "limited functionality", because there are models in the assortment with even more diverse capabilities.

Alpha2 and Alpha3.

Now these pumps are fully identical in their functionality. It happened after the possibility of independent hydraulic balancing of the heating system, which was previously present only at Alpha3. This is a very convenient solution that deserved an informal nickname "Medicine from the cold".

For hydraulic balancing, you will need Alpha Reader, which is installed on the electronic unit. It is purchased separately, it is not included. APLHA Reader transmits information from the pump to the smartphone or iPad. You will also need a free Grundfos Go Balance application to be installed on the gadget. Further procedure is carried out under the guidance of an application that will give out detailed instructions for each stage of the hydraulic balancing of the entire system. Alpha2 and Alpha3 pumps allow the coolant consumption in any heating system ("warm floor", two or one-pipe system, a dead-end, radiator network without a thermal head or with permanent flow) On all radiators and circuits of "warm floors" in real time. This allows you to reduce possible errors, without which it is not necessary even with the most thorough theoretical calculations.

However, Alpha2 and Alpha3 are interesting not only for self-balancing. These are modern multifunctional units, perfectly cope with work in different conditions. They have three fixed speed modes, three modes with a permanent pressure drop and three modes of proportional control - such a rich selection opens the possibilities of accurate system settings, the pump becomes universal. There are two more important additional functions: "Night economy regime" and "Summer Mode". In Denmark, where these pumps were developed, they are in great demand. First, the heating of the premises, in which there are no people at night, is simply irrational. Secondly, this is a question of compatibility. Pumps are suitable for working with modern boilers, where such a mode is present. Pragmatic Danes know a sense in savings, they are generally expensive with their heating. Therefore, in vain burn gas, firewood or coal is a non-disabilities.

As for the "summer regime" - this is a seasonal function. It allows you to start the heating in the fall without unnecessary problems. For example, the pumping of the pump shaft with a duty is simple. In fact, launch yourself the system several times during the summer - a real fruit. "Summer Mode" will support the performance of the system independently.

Grundfos Alpha2, became the first pump in which the AUTOADAPT mode appeared - naturally, Alpha3 also "inherited" him. This is a novelty from the company's engineers who pay great attention, primarily ease of use, and of course energy efficiency. The function has become a real breakthrough and a kind of standard for subsequent generations of circulation pumps. The AUTOADAPT mode makes it possible to automatically change the settings of the equipment when the needs of people living in the house are changed, or, for example. Change of season time. Using complex software algorithms, equipment electronics all the time analyzes the processes and depending on the indicators, selects optimal pressure. This is significantly saved by the resources of the heating system and the consumer money.

By purchasing Grundfos pumps, the consumer receives a very high-quality device performed by the highest European quality standards. That is why the manufacturer gives a guarantee from 2 to 5 years to various equipment models.

Separately should be said about engines. Do you know many pump manufacturers in which the rotor shaft and the bearing are made of ceramics? Most likely no, because in most models from Grundfos competitors, the shaft is made of steel, and the bearing of graphite. It is well known that hot water heats the iron and expands it. Over time, such a bearing is pulled out in the formed clearance between the shaft and the bearing, the scale falls and another garbage. Sooner or later it leads to breakage. In the case of ceramics, it is almost impossible.

In addition, in the pumps of the Alpha series, a four-pole synchronous electric motor with permanent magnets and a frequency converter is used. Rotors with permanent magnets give a larger efficiency in a different load range. Grundfos appreciates its customers and is ready to provide any help at any time. The program "Service for 24 hours" is represented in all cities of Russia, where there are representative offices of the company. Grundfos pumping equipment user can always call the hotline and get an answer to any question or call specialists to eliminate

Alpha2 pump - this is the most economical pump in the world with a record Energy Efficiency Index (EEI) for this type Equipment - 0.15 (according to TÜV research)

In addition to exceptional reliability, the pump has a wide functionality: three fixed rotational speeds, three mode of maintaining a pressure permanent pressure drop, three modes of proportional pressure drop control, patented AUTO function Adapt. and the function of automatic transition to night mode.

Features and advantages:

• Patented AUTO function Adapt. ;

Removal of air

To remove air from the pump at the time of its commissioning it is necessary to set the mode of high (III) fixed speed of rotation to a short period of time. After this procedure is possible to install the required mode of operation.

Increased starting point

The pump without problems will start even after a long downtime in several months

If the summer regime function has not been turned on before the summer season, lime deposits can potentially block the pump. Alpha3 during startup begins to vibrate, trying to scroll the rotor with an increased starting point to 27 N * m, thereby destroys any deposition of dirt.

Summer mode function

The function protects against the "zaking" pump and the heating system as a whole

IN heating systemsThat were not in operation for several months, lime deposits are often formed, potentially capable of preventing the normal start-up of the pump and the system before preparing for the heating season. The function of the summer regime included immediately before the start of the summer season protects the rotor of the pump and the heating system as a whole. Once a day, the pump will start and make a run at a minimum speed for two minutes, which is quite enough to protect the rotor and system. In this case, the consumption of electricity is reduced to almost an absolute minimum.

Protection against "dry" stroke

Built-in algorithm for protection against "dry" stroke provides unsurpassed protection and durability Alpha3

Built-in protection against "dry" stroke with automatic restarting allows preventing premature failure of the pump. The protection algorithm is a "thinking" mechanism that is able to determine the cause of the dry move: fluid leak in the system, the air "plug" or closed shut-off valves before the pump. Thanks to the protection against "dry" stroke life cycle Alpha3 is significantly increased.

Catalog coating hydraulic part

The special coating of the hydraulic part of the Alpha2 pump serves to effectively combat metal corrosion as an inside - in the case of using poorly prepared water as a coolant; It is also outside - in the case of the use of the pump in air conditioning systems, when a condensate is formed on the pump housing due to low temperatures of the coolant on the pump case.

Also, the cataphoresis contributes to the improvement of the hydraulic efficiency of the ALPHA2 pump.

Heat insulating casing

Now thermal losses through the pump housing will be less with the use of heat insulating casing, which leads to a decrease in energy costs during the operation of your heating system. In addition, the chances of burning about the pump hull tend to zero.

Modes of work

Maintain Permanent Pressure Differential Mode

This mode It is applied in those systems where the coolant consumption is variable in time, and the value of the pressure drop must remain constant. A bright example of such systems can serve as a collector wiring of a warm floor circuit (see Figure)

Proportional pressure drop control mode

This mode is applied in those systems where with the flow rate of the coolant varying in time, it is permissible to change the pressure drop in order to reduce electricity costs. Excellent example is a two-pipe system of a private house heating using temperature regulating reinforcement (See Figure).

Fixed Speed \u200b\u200bFrequency Mode

This mode is provided for those systems where the pump is required at the fixed speed. For example, to install boiler boot. And also for those systems where the operating point does not enter the characteristics field of the AUTO Adapt function. An example serves a single-tube system of heating of a private house without thermostatic reinforcement (see sinokun)

Note. This mode also serves to remove air when the pump starts.

Night mode

The ALPHA2 pump automatically switches to the night mode when the temperature drop in the pressure pipe is larger than 10-15 ° C for approximately 2 hours. The temperature drop rate must be at least 0.1 ° C / min. The transition to the normal mode occurs, as soon as the temperature in the pressure pipe increases by approximately 10 ° C.

Important: The pump must be installed on the feed line!

AUTO. Adapt.

This mode satisfies the needs of 80% of circulation systems in private homes.

Connect it and go

In Grundfos, we believe that complex can be made simple, and innovative technologies intuitive.

AUTO feature Adapt. Reflects this philosophy. It expands the advantages of electronic pump control and even makes it easier to install them. A pump with AUTOADAPT function constantly analyzes the system in which it is installed, and as the flow of the coolant changes, adapts under it.

What is AUTO. Adapt.?

Developed and patented by Grundfos, Auto Technology Adapt. serves several goals:

• Improving the engine speed control function;
• Independent check of the pump compliance with the pump;
• Achieving perfect comfort when minimum costs Energy.

New advantages

AUTO feature Adapt. In Alpha2, this is the second generation of well-known and recognized technologies who are familiar to our customers from the Magna series. Installing AUTO. Adapt. - Perfect choice for more than 80% of systems.

Second generation AUTO function Adapt. For Alpha2, has two significant improvements:

• It does not need to achieve the maximum of the pump performance curve to adapt to the requirements of the heating system;
• It allows the pump to adjust the curve characteristics as in the direction of increasing productivity and in the direction of the decrease.

Electronic control

GRUNDFOS with electronic control (E-pumps) pumps are able to exercise "intelligent" performance regulation. We integrate frequency converter To automatically adjust the speed of the engine rotation so that the pump creates the required pressure in the system.

"The function of proportional pressure" - implies pressure support depending on the feed. The pressure decreases in proportion to the decrease in the supply until the pressure value of 50% of the predetermined will not be reached at zero feed.

Avoiding permanent operation at one speed, Smart Pumps GRUNDFOS are functioning by a proportional pressure curve. This makes them much more efficient than standard three-speed pumps.

Speed \u200b\u200bcontrol reacts to change conditions

The need for heating various rooms consists of several factors. They include the temperature outside, the level of sunlight, the use of electrical appliances and other heat sources.

A pump equipped with frequency regulation automatically adjusts performance in accordance with the change in needs. This allows you to match the thermostat settings, while spending the minimum amount of energy.

Standard pump - unjustified costs

The standard three-speed pump is operating at a fixed rate, regardless of the actual need for heating. This is unjustified actions, for example, such as driving a car, not giving gas pedals.

This means that the pump creates pressure even when it is not required, which causes noise in the system and irregular energy consumption.

E-pump - much more efficient

Smart E-Pump from Grundfos does not create overpressure. Continuing comparison with the car, the E-pump slows down the gas supply to slow down, and this happens whenever it can slow down in itself, without more effort.

Result? Significant reduction in power consumption. Pumps with electronic control and low value of EEI energy efficiency index, provide savings up to 80% compared with conventional pumps (class D). In normal circumstances, to recoup the initial additional costs of buying a new pump, the final consumer takes about two years. In combination with reputation, level of quality and reliability grundfos companyThis means saving funds for many years.

HOW IT WORKS?

Alpha2 with auto function Adapt. Selects the minimum possible pressure that meets the requirements of the system. It will constantly find a working point that provides the optimal level of comfort with minimal energy consumption.

FACTORY SETTINGS

Installing AUTO. Adapt. Alpha2 begins at a factory with a given working point on a reference curve. This proportional pressure curve is located in the center of the Auto regulation area. Adapt. .

The pump begins to analyze the heating circuit with a given working point. If the current working point deviates from the time specified in time, the pump automatically adjusts the corresponding performance.

In other words, if the requirements of the heating system exceed the specified operating point, the pump will choose an increased proportional pressure curve. If the requirements are below, a low curve will be selected.

New settings

When the adjustment of the proportional pressure curve is changed to adapt to the requirements of the heating system, AUTO Adapt. Automatically sets a new reference operating point. With new installations, the process begins anew: AUTO Adapt. It will be constantly adapted to changes in the heating scheme.

Installers and consumers

As a result of several studies, it turned out that most installers never define specific parameters and do not produce hydraulic calculations of those heating systems in which they set pumping equipment. Therefore, it is difficult for them to choose the appropriate pump intended for work in a specific system, install it and configure it correctly.

With Alpha2 installer after completing the installation and select AUTO function Adapt. may leave, being confident that the pump is adapted to the system and automatically select the optimal settings.

Consumers of heating systems require savings in accounts for housing and utilities and electricity, reliability and durability of equipment, - Alpha2 corresponds to these requirements and even exceeds them, supporting the balance between energy efficiency and the optimal level of comfort.

One of the most attractive characteristics that possess circulating pumps – price. Pumps of this series are designed specifically to regulate the operation of heating systems. No less demanded circulation pump Grundfos (Grundfos), fully controlled by one key. Buy circulating Pumps of this series you can in our company.

The classic installation scheme of the heating system is the natural circulation of the coolant. Along with the advantages, such a connection has a number of disadvantages: the slow motion of the coolant, which entails a decrease in its temperature in the return, and uneven distribution hot water Battery. These factors reduce the efficiency of the heating system as a whole.

The solution to this problem will be the installation of the pump Grundfos for forced circulation of hot water.

1 varieties of pumps Grundfos for heating

Danish company releases two types of pump: with dry and wet rotor.

Circulation pumps for GRUNDFOS heating systems with dry rotor have high efficiency and high power. For efficient work Such equipment needs a large amount of coolant, so they use them at large industrial enterprises or in the heating systems of buildings with a large area.

For private household heating systems, Grundfostp dry rotor pumps are extremely rare. Distinctive feature Models - not in contact with water rotor. The circulation pump of dry-type hydropos when the engine is turned on produces a lot of noise.

Pumps with a wet rotor have an efficiency of no more than 50%, but they work almost silently. For high-quality operation of such equipment, it is necessary to use high quality coolant, then the service life of the device is extended to 10 years. The feature of the design of such models is immersed in the coolant rotor, as well as the exclusion of the formation of air traffic jams in the system.

Grundfosups pumps with a three-speed switching system are suitable for home heating systems.. Circulating pump speed control is carried out in manual mode or automatically. The second option allows to reduce energy consumption and set the mode of operation of the equipment for a long time.

For two-circuit boilers and systems "" use Grundfosalpha pumps.

1.1 Benefits of Pumps Grundfos

The Grundfos heating circulation pump has a number of advantages that determine the popularity of equipment in different fields:

1. Pumps from the Danish manufacturer, Grundfus have low weight and overall dimensions.
2. In operating mode, the pumps with a wet rotor are almost silent and do not create discomfort.
3. Heating equipment consumes electricity by 60% less than similar pumps of other manufacturers, so their use is economically appropriate.
4. The simplicity of the design of the unit allows you to repair it if necessary, do not attract specialists.

The pump engine is made of high-quality aluminum, the housing of the cast iron, and the steel rotor is made by a full-scale part. These are durable selected in such a composition so that the device can withstand the high-temperature coolant.

This is especially true of ceramic bearings, since ceramics not only reduces the noise when rotating the rotor, but also withstands the rigid operating conditions for at least 10 years.

Recently, the manufacturer of Grundfos produces pumps with bearings from a technopolymer and a ceramic rotor. This solution increases the efficiency of the device and extends the service life.

1.3 Secrets of new Grundfos pumps for heating (video)

2 Nuances of Montaja

To achieve the efficient operation of the unit, it is necessary to install it only on the horizontal surface. The wet rotor devices are mounted on the feed circuit, and with dry - exclusively to the return, since in the pumps of dry type, sealing gaskets are made of rubber or paronite. The high temperature of the coolant displays them in order rather quickly.

IN obligatory In front of the grindfos heating circulation pump, a coarse filter is installed, which will save the equipment from entering impurities and extends its life.

If the house is often disconnected by electricity, then for uninterrupted, bypassing bypass.

When choosing pump equipment from GruDFos, attention to the magnitude of the pressure, since it depends whether the unit will be able to raise the coolant to the desired height. A single-tube heating system involves the inclusion in the pump chain with a smaller pressure than the two-pipe.

3 Features of Equipment Grundfus

Compliance with the rules of operation and installation will allow the use of Grundfus pumps as efficiently as possible:

1. For independent installation Pumping It is impossible to confuse the direction of the nozzles, since the arrow is applied on the body, indicating the direction of rotation of the rotor, that is, the movement of the coolant.
2. In the configuration of the device, the fasteners are not provided, so they will need to take care of them in advance.
3. The circulation pump must only work at the positive indoor temperatures. If the device was stored or transported at temperatures below 0 0 s, then it is recommended to run it after installation no earlier than a day.
4. The optimal connection to the network is a separate cable from the distribution panel.

Centrifugal Console Pumps Grundfos NB, NBE and NK

The centrifugal console pump is used to maintain pressure in the system at a constant level. One of the most common working media of cantilever pumps is water, but other liquids can be used, similar to physical properties and chemical composition. Main areas of application of pumping equipment of this species - water supply, industrial systems Increased pressure and pumping fluid, irrigation, as well as heating, air conditioning and ventilation.

Differences of Centrifugal Console Pumps Grundfos NK, NB, NBE

They are a block structure, where each element is an electric motor, a coupling, the pumping part is made separately, but is connected to other elements and is mounted with them on one frame.

Unlike NC pumps, there are single-stage, monoblock structures, in which the electric motor, and the pump itself is integrated into a single block.

Both series are produced both in vertical and horizontal design. Like centrifugal Grundfos NB console pumps and Grundfos NK have high durability and do not need constant maintenance.

They have an engine with a built-in frequency converter and a software application that allows electronic control and adjusting the speed of the engine. NBE series pumps are compact and can fit into a limited space.

Single-stage centrifugal pumps TP Grundfos (Denmark) are multipurpose pumps suitable in various applications. Available both single and dual pumps (TPED).
Pumps are designed to circulate hot or cold water In domestic, departmental and industrial applications in systems, such as:
heating systems;
district boiler houses;
Systems central heating apartment buildings;
air conditioning systems;
cooling systems.
In addition, this pump series is used to pump fluid and water supply,
for example, in the following systems:
detergent systems;
household hot water systems;
General industrial systems.
Grundfos TP pumps are pumped, non-aggressive, explosion-proof fluids that do not contain solid inclusions or fibers that can have a mechanical or chemical impact on the pump.
Examples:
Water for central heating systems (water quality must comply with the requirements of adopted water standards in heating systems);
coolant;
household hot water systems;
industrial liquids;
Softed water.
If the water contains mineral / synthetic oils or chemicals, or, in addition to the water, other liquids are pumped, it is necessary to choose the corresponding end-stacking seals.
Pumps with electric motors with a capacity of up to 11 kW can be installed in horizontal or vertical pipelines. Pumps with electric motors with a capacity of 11 kW and above can only be installed in horizontal pipelines with electric motors in a vertical position.
The pump is equipped with an asynchronous engine cooling fan
Design features:
The design with the "dry rotor" makes them less sensitive to inclusion in the pumped medium than the pumps with the "wet rotor".
The pump is centrifugal with suction and exhaust pipes on the same line.
The new original design of the coupling compound reduces the wear of bearings and the end seal, ensuring reliability and high efficiency.
The design of the impeller and the spiral case reduces the pins and increases the efficiency.
The cataphoraza coating used for the outer and internal surfaces of pig-iron parts increases corrosion resistance and, due to small roughness, contributes to an increase in efficiency.
Energy Efficiency Energy Efficiency Electric Motors (EFF1) also contribute to the GRUNDFOS TP pumps become the most economical on the In-Line pump market, regardless of whether they work in full or partial load.
TP pumps have the design of the extraction from above, i.e. The head part (electric motor, pump head and impeller) can be dismantled for maintenance or repair while the pump housing remains on the pipeline.
The pump is equipped with an unbalanced bellows seal. Shaft seals correspond to EN 12756. Connecting to a pipeline with pipe thread or flanges.
Most of the pump sizes can be supplied both in single and dual versions with standard motors or engines with built-in frequency converters (TPE and TPED models). Maximum power of engines with an AF-22 kW.
