In Russia, the official representative of the international company Wilo is Wilo Rus LLC. She has many partners in many cities of the country. Each partner is issued a certificate that confirms his right to sell products of this brand. We do not recommend buying anything from non-certified dealers, as you can run into a fake.

Heating pumps Glandless forks

The technical characteristics presented in the catalog of Glandless Fork pumps allow them to work in autonomous heating pressure up to 10 bar. The coolant is pumped through the impeller mounted on the shaft (rotor). The peculiarity of this line is that the rotor must always be immersed in water (coolant), which performs two important functions: lubrication and cooling. This condition imposes certain installation requirements - the rotor must be in a horizontal plane. By following this simple rule, you will not have to think about repairing Vilo pumps (see).

The range is divided into two categories: with automatic power control and with manual power control. A total of 21 models of pumps with a wet rotor are presented. Their body is made of gray cast iron or bronze, the rotor is steel, the impeller is made of plastic, and the bearings are metal-graphite. The unit can be installed on the circuit by means of a threaded or flange connection. The last option is typical for Wilo industrial pumps.

Until now, it is the most popular and economical.

Before that, calculate the required heat output.

In autonomous heating, you need through mixing unit, which regulates the temperature of the coolant.

A coarse filter (sump) must be installed in front of the pump. It is needed so that solid particles do not get on the impeller blades and break it. The coolant always contains deposited salts or metals (scale), and the quality of water in central networks is generally terrible.

The pump is attached to the circuit by American women - a detachable connection, which, in turn, are installed on ball valves. This will allow you to cut off the pump from the circuit at any time and remove it for repair or maintenance without draining the water from the entire system. . without the provided make-up from the water supply - for a long time.

The circulation pump is an integral element of any forced circulation heating system. It is from this small device that the stability of the circulation of the coolant through the pipeline depends.

Pumps from the manufacturer WILO can rightly be considered one of the best.

Why do you need a circulation pump at all

In some cases, you can completely do without this element, when we are talking about systems with natural circulation. In this case, the coolant moves through the pipes due to the pressure difference that occurs when the water is heated in the boiler. The coolant expands when heated, part of it is simply squeezed out up the supply pipe, rising to the highest point, the water enters the radiators and, gradually cooling down, moves back to the boiler ().

The only advantage of such an organization for heating housing can be called absolute independence from electricity. This is important, for example, when heating country house or cottages in a remote area. In addition, the absence of moving parts in the system prolongs its service life.

But it is still better to install a circulation pump for heating Vilo before entering the boiler.

As for the advantages, the installation of such a device makes it possible:

  • ensure stable circulation of the coolant through the pipes. Modern models are able to reduce the number of revolutions themselves, making the heating of the house not so strong. This quality is especially useful in terms of financial savings;
  • the pressure will not depend on the diameter of the pipe (it is better not to use small diameters in systems with natural circulation);
  • installation of the pump does not reduce the durability of the system as a whole, modern models can last 20-30 years.

Of the shortcomings, one can only note the small cost of electricity and noise. But the boiler is usually located in a separate room, and the price of electricity is not so high as to refuse the pump.

Classification of circulation pumps

As for the principle of operation, all devices of this kind can be divided into 2 types:

  • with a "wet" rotor;
  • with a "dry" rotor.

For heating a relatively small house, options with a “wet” rotor are preferable. They got this name due to the fact that the rotor (the part that rotates) is placed directly in the pumped coolant.

Circulation pumps for Wilo heating of this type have the following features:

  • almost completely silent;

Note! In small houses, sometimes it is not possible to move the boiler away from the living quarters, so noiselessness is an important advantage.

  • lubrication is not needed - the rotor is in the water, so the coolant itself performs its role;
  • for greater reliability, the rotor chamber and the stator are separated by a durable stainless steel sleeve;
  • the only and rather significant drawback can be considered low efficiency - about 50%.

Note! A "wet" pump must be installed so that its shaft is necessarily horizontal.

To operate a powerful system, it is better to use a “dry” Wilo circulation pump for heating. Unlike the “wet” analogue, its rotor does not contact the coolant at all, and it is possible to achieve a high degree of tightness due to the pumped liquid itself.

During operation, a thin film of liquid finally seals the microscopic gaps between the rotating surfaces. Over time, the o-rings grind a little, but the fact that they are spring-loaded and simply shift by the amount of wear solves the problem, the main thing is that the grinding occurs evenly.

The main advantage of "dry" devices can be called an efficiency of more than 80%. And the disadvantages can be recorded as a high level of noise, therefore, such pumps are used mainly in powerful systems.

More about modern circulation pumps

One of the main requirements for a modern heating system can be considered flexibility - that is, the ability to adjust its power over a wide range. Circulation pumps for Wilo heating systems are the best fit for this.

In the distant past, circulation pumps were unregulated, that is, they could not reset the rotor speed. This led to the fact that the heating system worked at approximately the same power at any time, even when there was no particular need for it.

Features of the operation of variable pumps

Nowadays, special attention is paid to energy saving issues, so unregulated devices are practically not installed in new heating systems.

The use of adjustable devices allows you to:

  • change the rotor speed at any time, for example, to save energy at night, the device itself slows down;
  • set any operating mode manually, this is useful if the owner plans to leave home for a couple of days. In this case, the heating can be left at a minimum level.

Note! The German manufacturer Wilo produces models for work in very harsh conditions. If the lime content in the water is high, then you should pay attention to the Wilo Star models.

As a rule, the Wilo heating circulation pump can operate in several modes:

  • PP1 and PP2- in this case, the pressure in the system will change, and the designations correspond to operating characteristic with maximum pressure (PP1) and minimum (PP2);
  • SR1 and SR2- in this case, the pressure remains unchanged, and the pump adjusts to the flow rate of the coolant by changing the number of revolutions of the rotor;
  • operating modes numbered I, II and III. The unit corresponds to the speed at the minimum operating characteristic, II and III - the speed at the average and maximum speed;
  • It is possible to switch between day/night modes.

Placement and installation rules

If it is not possible to invite specialists, then the installation can be done by hand.

You just need to remember a few simple rules for installation:

  • it is forbidden to place the pump at the outlet of the boiler - the hot coolant will shorten the life of the device at times. It is considered optimal to place it on the pipe section in front of the boiler entrance;
  • the arrow on the body shows the direction of movement of the coolant, it must be directed towards the boiler;

  • when the pump is already installed and filled with water, air is removed from it;
  • the pump is installed so that it can be quickly isolated from water ingress if necessary. To do this, a bypass is arranged and a shut-off valve is installed.

The installation instructions for the pump are not particularly complicated, and threaded connections are used, so that if necessary it can be quickly removed for repair or replacement. Before installation, the boiler must be cut off shutoff valves. Also installed during installation check valve(with the exception of open systems) and a filter.


Heating systems that use the natural circulation of the coolant are slowly becoming a thing of the past. Their low productivity, narrow focus and lack of high pressure in the system affect, which is important for houses with a large area.

Gradually replaced by natural circulation in heating systems ah comes forced, where one of the main units is the circulation pump.

Circulation pumps from WILO: design features and main characteristics

Currently, the domestic market is extremely rich in all kinds of circulation pumps for installation in a heating system.

It should be noted that among them there are both really high-quality, well-designed models, as well as outright Chinese fakes that are not able to work for more than one season.

Naturally, if the heating system is chosen, as they say, "for centuries", then all the units installed in it must be of high quality, reliable and productive.

Circulation pumps for Wilo heating systems, produced by the eminent German concern, are in great demand among domestic consumers.

As you know, the Vilo heating circulation pump is the "heart" of the system modern heating And the manufacturing company understands this.

Thanks to over 100 years of experience, unique equipment and careful selection of materials, Wilo pumps are distinguished by their performance, power and reliability. Models are presented for both civil and industrial buildings.

Tip: Vilo pumps are presented in a large assortment, and therefore it will not be superfluous to consult with specialists before buying a specific model. Only professionals will give specific advice and help you choose the best unit for each specific case.

Vilo circulation pumps - performance and quality

AT modern systems heating circulation pumps for Wilo heating perform an extremely important task - they ensure the rapid movement of the coolant in the network. As a result (and the instruction for Vilo pumps says this), heat transfer improves almost several times, and the efficiency of the system increases.

Also, if there is a Wilo circulation pump for heating in the circuit, you can significantly save on pipes, because the lines (due to forced pressure build-up) have a significantly smaller diameter than if natural circulation was used.

As for the equipment itself, Vilo pumps are practically silent, reliable and practical, have compact dimensions and do not require any special maintenance.

Any circulation pump from Wilo SE is a modern and productive unit, it works for a long time and without fail. It should be noted that installing it with your own hands does not turn into some kind of complex and time-consuming operation. And the price for such equipment is much lower than for analogues presented on the domestic market.

A wide range of Wilo pumps – an opportunity to make your heating system efficient

The domestic market offers just the same huge selection modern, reliable and high-quality pumps of this German company. In many photos and videos posted on the Internet, you can easily see the main range of equipment that the Wilo group really produces in abundance.

Among the most popular models Vilo circulation pumps can be distinguished:

  • WiloStar-RS and Model WiloStar-RSD- low-power, but at the same time reliable pumps, which are quite inexpensive. Ideal for various home heating systems. A built-in manual speed switch is available to increase the efficiency of the equipment. Pumps from this series are suitable for heating rooms with an area of ​​200-750 sq.m;

Circulation pump

  • Wilo Stratos ECO effectively replaced the previous generation of circulation pumps, ideal for integration into large heating systems in which the power of the boiler plant exceeds 25 kW. This is electronic pumps, power and performance adjustment in which is carried out by means of a special system. Circulation pumps of this class are suitable for small cottages (more than 80% of existing heating systems). A feature can be called low power consumption and the ability to work with a coolant even at negative temperatures;
  • TOP-RL and TOP-S model from the manufacturer Vilo - circulation pumps designed specifically for buildings whose area exceeds 1400 square meters. meters. These are three-phase and dual pumps, the operation of which is possible in modes of increased efficiency and productivity;
  • Wilo TOP-Z– pumps designed for systems where deposits of magnesium and calcium salts are possible. Such equipment perfectly copes with any tasks, ensures the normal operation of heating even with low water quality.

Benefits of using Vilo pumps in heating systems

Modern circulation pumps for Wilo heating systems are an excellent choice for any property, be it small country cottage or industrial plant.

The use of Vilo pumps for systems with forced circulation of the coolant allows you to get a lot of advantages:

  1. Improving the efficiency of the coolant flow through pipelines, better heat transfer even in the farthest corners of the heating system;
  2. Reduced fuel consumption by boilers and, as a result, significant financial savings. This is especially true for large boiler houses at manufacturing enterprises and other facilities;
  3. Extension of the period of trouble-free operation of the heating system. Circulation pumps are able to create quite high pressure in the pipeline, which eliminates the deposition of salts from the coolant . In turn, blockages and narrowing of pipe diameters are excluded.

Conclusion

As can be seen from the above material, such pumps for heating systems (although their installation is also possible in hot water pipelines) can increase efficiency and productivity, reduce costs, and also eliminate breakdowns.

Pumps from an eminent German brand are surprisingly well integrated into existing and functioning heating systems (due to their low weight and dimensions). They provide a fast flow of coolant and its circulation through all radiators.

Nevertheless, their choice must be approached with all responsibility, taking into account the area of ​​\u200b\u200bheated premises, as well as friction losses in pipes.

The choice of WILO circulation pumps is a great opportunity to become an owner effective system heating. Such equipment fully meets all quality standards, are made only from the best materials and innovative technologies.

- see here.

Heating systems in which the coolant circulates naturally according to the law of gravity are becoming less and less common, and only where a small area is heated using a single-circuit boiler.

Forced circulation equipment

Ensure quality travel hot water Wilo circulation pumps will help you through pipes and batteries. They do an excellent job with their functions in large houses with complex branching of heating systems. Do right choice a modern and compact device that will show effective operation will help an overview of Vilo models and instructions from the manufacturer.

All German-made units are distinguished by reliability, ease of installation and the ability to reduce the diameter of the pipes, which reduces the estimate for heating installation.

For the full heating of private houses, two series of Wilo pumps were specially developed, which differ somewhat in technical characteristics.

This range of pumps has a small capacity and is suitable for use in houses whose area is in the range of 200 - 750 m².

Peculiarities

The main advantage of this series is the wet type rotor. It is continuously immersed in the pumped energy carrier, which does not allow the graphite bearings to dry out. Another plus of Star-RS is that a technical polymer is used here for the production of a rotor wheel.


This material is resistant to high temperatures, typical for heating systems, and is not afraid of their sharp drop.

Housing and fasteners

The Vilo circulation pump is connected to the pipeline using a thread, the diameter of which may vary depending on the model. The unit has a cast iron body and stainless steel shaft.


A comfortable working environment for such a device is water or a water-glycol composition. Star-RS pumps for forced heating systems are virtually silent. They quickly pump coolant and consume little electricity.

Advantages

The German equipment of this series has gained great popularity due to the following advantages:


  • the body is coated with an anti-corrosion cataphoretic composition;
  • revolutions are regulated using a three-stage mechanical switch;
  • hardy metal-graphite bearings do not wear out at aggressive temperatures;
  • low cost.

Working conditions and installation

Devices for heating systems of the Star-RS series can work in temperature regime+10 +110 °C at pressures up to 10 bar, and this makes it possible to use them in air conditioning.


When installing the Fork Star-RS, the manufacturer's instructions must be strictly followed, which states that:

  • tie-in is possible after installation and flushing of pipes from chips;
  • the terminal box and the motor must be reliably protected from moisture;
  • the pump axle must be located strictly horizontally.

TOP-S series

Models of this series are designed for use in buildings up to 1400 m². Such pumps with one or three-phase connection guarantee an accelerated pumping of hot water through pipes and radiators.

In their manufacture, materials similar to the previous line from the German company Wilo were used.

Working conditions and installation

The equipment operates at a temperature of +20 + 130 ° C, and for two hours the units can operate smoothly with an increase maximum temperature at 10°C. Permissible pressure is 6, 10 or 16 bar (special version). As in the previous case, the speed is controlled by a three-stage switch.


The Vilo TOP-S series is available with increased engine protection and a thermal insulating casing. The versatility of Wilo equipment is due to the double-sided cable connection and the complete set with a combination flange 6/10 bar (for models with an internal diameter of 40 - 65 mm).

Product Advantages

Circulation pumps from the German company Wilo successfully compete with similar devices due to the fact that they are made from anti-corrosion materials and can work with various coolants.


They are durable and easy to operate, besides they consume electricity economically. Another important factor that affects demand is the compact dimensions of the units with their multi-stage protection.

Signs of the original

Given the popularity of Vilo products for heating systems, there is a risk of acquiring a fake. To avoid trouble when buying, pay attention to the following signs of the original:

  • the minimum price is 80 USD;
  • the presence of a serial number on the case;
  • manufacturer's instructions;
  • two mounting bolts out of four (for a fake - 4).
