Heating systems in which the coolant circulates naturally according to the law of gravity are becoming less and less common, and only where small area heated with a single-circuit boiler.
Forced circulation equipment
Ensure quality travel hot water through pipes and batteries will help circulation Wilo pumps. They do their job well in big 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 impact resistant high temperatures characteristic of 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 practically 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 without interruption with an increase in the maximum temperature by 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 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).
Model overview
In order to have an idea about technical parameters Vilo products, we suggest that you familiarize yourself with the main parameters of the devices. The table shows average price product shown on Russian market plumbing.
In Russia official representative 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 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 metal-graphite bearings. The unit can be installed on the circuit by means of a threaded or flanged 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, it is necessary through a mixing unit that 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 Americans - detachable connection, which in turn are set to 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.
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, natural circulation in heating systems is replaced by forced circulation, where one of the main units is a 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.

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.
Use of Vilo pumps for systems with forced circulation coolant allows you to get a lot of advantages:
- Improving the efficiency of the coolant flow through pipelines, better heat transfer even in the farthest corners of the heating system;
- Reduced fuel consumption by boilers and, as a result, significant financial savings. This is especially true for large boiler houses on manufacturing enterprises and other objects;
- 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.
