Wilo circulation pumps. How to choose a circulation pump for heating Wilo: instructions, reviews, characteristics Circulation pumps WILO-STAR-RS

Heating systems in which the coolant circulates in a natural way according to the law of gravity, occur less and less, and only where the small area is heated with a single-circuit boiler.

Equipment for forced circulation

Provide high-quality movement of hot water through pipes and batteries WILO circulation pumps will help. They perfectly cope with their functions in large homes with a complex branching of heating systems. Make the right choice of a modern and compact device, which will show effective work, will help the view of the models of the Wile and instructions from the manufacturer.

All German aggregates are distinguished by reliability, ease of installation and the ability to reduce pipe diameter, which reduces the estimate for the installation of heating.

For full heating of private houses, two series of Wilo pumps were specifically developed, which are somewhat different among themselves according to specifications.

This line of pumps has a small power and is suitable for operation in homes, the area of \u200b\u200bwhich is in the range of 200 - 750 m².

Features

The main advantage of this series is a wet rotor. It is continuously immersed in a pumped energy carrier that does not allow to dry up graphite bearings. Another plus STAR-RS is that a technical polymer is used to produce a rotary wheel.

This material is distinguished by stability before exposure to high temperatures characteristic of heating systems, and their sharp drops are not afraid.

Case and fasteners

With a pipeline, the circulation pump is connected by a thread, the diameter of which may differ depending on the model. The unit has a cast iron case and a steel stainless steel shaft.

A comfortable working environment for such an appliance is water or water-glycolic composition. Star-RS pumps for forced heating systems are almost silent. They quickly patch the coolant and consume little electricity.

Benefits

The German equipment of this series has gained great popularity thanks to such advantages:

the housing is coated with anti-corrosion cataphoresis;
revolutions are adjustable using a three-stage mechanical switch;
still-out metallographic bearings are not wears in aggressive temperatures;
low cost.

Working conditions and installation

The Star-RS series heating systems can operate in temperature mode +10 +110 ° C at a pressure of up to 10 bar, and this makes it possible to use them in air conditioning.

When installing, Star-RS should strictly follow the manufacturer's instruction, which states that:

the insertion is possible after installation and flushing pipes from chips;
clem box and motor must be securely protected from moisture;
the pump axis should be located strictly horizontally.

Top-S series

Models of this series are designed for operation in buildings with an area of \u200b\u200bup to 1400 m². Such pumps with one or three-phase connections guarantee the accelerated hot water pumping through pipes and radiators.

Materials similar to the previous line from the German company Wilo are used in their manufacture.

Working conditions and installation

Equipment functions at a temperature of +20 + 130 ° C, and for two hours, the aggregates can work smoothly with increasing the maximum temperature by 10 ° C. Permissible pressure is 6, 10 or 16 bar (special execution). As in the previous case, revolutions are adjusted by a three-step switch.

The Top-S series is available with increased engine protection and thermally insioning casing. The versatility of Wilo equipment is due to a two-way cable connection and a complete set with a combined flange 6/10 bar (for models, the inner diameter of which is 40 - 65 mm).

Advantages of products

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 convenient to manage, besides economically consume electricity. Another important factor that affects demand is the compact dimensions of the aggregates during their multistage protection.

Signs of origin

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

the minimum price is 80 USD;
the presence of the factory number on the housing;
manufacturer's instruction;
two fastening bolts of four (in fake - 4).

4 Description of pumps and accessories

4.1 Description of the wet stroke pumps

In the wet pumps, all moving parts including the engine rotor is washed with liquid. Shaft seals are not required. The liquid lubricates the sliding bearings, cools them and the rotor.

Paired pumps are identical and installed in one case. They are equipped with an integrated switching valve. Each pump can work autonomously, as well as both - at the same time. Paired pumps can be used in two different versions:

Working and reserve pump (in case of failure of the main pump, the reserve work is included in the work);

The main and peak pump (the latter is included in addition when peak loads).

At the same time, both pumps may vary by installed capacity. Installation with a paired pump, therefore, can be configured to an initiative production situation.

Pump engine:

For single-phase current 220 V: Special engine only for use with single-phase current;

For three-phase current 380 V: Special engine only for three-phase current. The engine can not be connected according to the scheme of the matte.

Engine protection:

Pumps with an internal diameter of 25/30/40 and an impeller up to 80 mm (single-phase and three-phase current) do not need the engine protection. The overload current cannot damage the engine and lead to its blocking.

Engines of all other pumps are equipped with contact winding protection (WSK). With an unacceptable engine overheating, protection by switching switch, for example, SK 602/622 or C-SK (accessories), turns off the engine. After cooling the engine, the pump can be turned on again. To protect the engine, a switch (SK 602, SK 622 or C-SK) is strongly recommended. When using Switchable devices WILO for automatic regulation, there is no need for special switches, as they are already integrated into the switching devices.

To control the paired pump, an automatic switching device S2R3D is required. The switch to protect the engine is also integrated into the switching device.
Switching the number of revolutions:

All pumps have a 4-speed manual switch (on the terminal box). At the lowest stage, the number of revolutions is reduced by 40-70% of the maximum. Electricity consumption drops at the same time by 50%.

Pumps with single-phase current motors as a switch have a rotating knob on the terminal box housing (Fig. 1a, pos.1).

Pumps with single-phase current motors P 2 less than 75 W have the ability to connect a two-stage automatic switch (S2R-H, timer).

On pumps with a three-phase current motor, switching the number of revolutions is carried out by switching the 4-speed plug on the terminal box. In addition, it is possible to connect a 2/4-speed automatic switch (Fig. 1b, pos.1).
Automatic control and adjustment devices:

Automatic control devices and pump power adjustment depending on hydraulic needs are available in the Wilo program.

5 Cabinet and Installation

5.1 Installation

Installation is made after the end of all welding and plumbing works and washing the pipe system. Pollution can disrupt pumps.

- Pumps must be mounted in well-visible places so that in the future it can be easily checked or replacing the pump.

It is recommended to install the shut-off valve before and after the pump. This disappears the need to re-fill the system when replacing the pump. The reinforcement should be mounted so that in the event of a duct water does not fall on the electric motor and the terminal box.

Installing the pump in the system with an open expansion tank is always made after the location of its connection.

Installation to produce without mechanical stress and only with a horizontally located pump shaft; The position of the installation is followed as indicated in Figure 2.

The arrow on the pump housing shows the flow direction.

The engine terminal box should not be directed down, because water can easily get into it. If you need to rotate the engine housing.

ATTENTION!
Gaskets do not damage.

ATTENTION!
When insulated pipelines, only the pump housing is insulated. The engine must remain open.

Pumps equipped with a plug module, air access to the module must be free.

5.2 Electrical connection

WILO pumps can be connected to 220/380 V electrical network and to the European network 230/400 V.

The electrical connection must be made strictly according to the manual with the plug connections or the multipole switch with the minimum distance between the contacts \u003d 3mm.

To ensure protection against water and reduce the load on the sealing nut, you must apply a cable of sufficient diameter.

When installing pumps in systems with water temperature of more than 90 ° C, a temperature cable must be applied, which in no case should not touch the pipeline or with the pump housing.

Type of current and voltage in the network is risen and compared with data in the table on the pump.

- Observe the type of pump data.

- Network connection and connection of the SK 602/622 switch, respectively, the schemes (Fig. 3a to 3E) are executed (see also 1.22 and 4.1):

3A: 220 V, non-blocking engine.

3B: 380 V, non-blocking engine.

3C: 220 V, with WSK (Contacts of thermal protection of the engine winding).

3D: 380 V, with wsk.

3e: When installing the switching plug module C-SK, the 3D scheme is replaced with 3E.

Run grounding.

When applying other defense devices, terminals 15 and 10 (WSK) must be connected to the engine control circuit (max. 250 V) together with the device that prevents re-inclusion. Then the pump in all four steps is protected.

ATTENTION!

- The thermal switch setting must be made according to the appropriate maximum current for the selected speed of the revolutions (CMT-Table).

When connecting automatically working switches, follow the appropriate installation and operation instructions.
6 Commissioning

6.1 Filling the system and air removal

The system is properly fill in properly. Removal of air from the system occurs independently after the short-term power on the pump. Short-term work "on dry" does not harm the pump. If direct air removal is required from the pump, it is possible to produce this as follows:

Disable pump;

Close the shut-off valve at the output;

Carefully unscrew the screw to remove air (Fig.4).

- the pump shaft carefully push back;

Electrical parts protect against liquid and steam;

Turn on the pump;

After 15 ..... 30 seconds of work Pump Turn off and twisted air output screw;

Armature Open and turn on the pump.

ATTENTION!
With an open screw hole, depending on the pressure value, the pump can be blocked.

6.2 Adjustment

- Checking the direction of rotation of three-phase engines:

Before checking the rotation of the screw on the front of the engine, unscrew. Through short-term inclusion, check the direction of rotation of the shaft with an arrow on the plate. With the wrong direction of rotation, change 2 phases.

- Switching the number of revolutions:

Single-phase current engines: Switching between 4 steps of the speed number is performed manually by the engine terminal box switch. Three-phase current motors: Switching between 4 steps of the number of revolutions is performed manually by switching the 4-speed plug on the engine terminal box. Loosen the central bolt and set the 4-step plug with the arrow to the desired level of the number of revolutions. The central screw is tightened again.

The heating systems in which the natural circulation of the coolant is used, slowly go into the past. It affects their low performance, narrow orientation and lack of high pressure in the system, which is important for houses with a large area.

Gradually, a coercive, where one of the main units is a circulation pump is coming to replace the natural circulation in heating systems.

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 the heating system.

It should be noted that there are among them as really high-quality, competently developed models and frank Chinese fakes that are not able to work for more than one season.

Naturally, if the heating system is chosen, as they say, "on the century", then all the aggregates, in it installed, should be high quality, reliable and productive.

Circulation pumps for Wilo heating systems are enjoyed with great demand among domestic consumers, whose production is engaged in the famous German concern.

As you know, the circulation pump for heating Vylo is a "heart" of the system of modern heating and the manufacturer's company understands.

Thanks to more than 100 years of experience, unique equipment and a thorough selection of materials, WILO pumps are characterized by their capacity, power and reliability. Models are presented for both civil and industrial buildings.

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

Circulation pumps VYOOM - performance and quality

In modern heating systems, the circulation pumps for Wilo heating perform an extremely important task - provide the rapid movement of the coolant on the network. As a result (yes, the instructions for the pumps of this says this), improves almost many times heat transfer, the efficiency of the system increases.

Also, if there is a circuulating pump Wilo for heating in the circuit, it is possible to significantly save on the pipes, because the highway (due to forced pressure injection) have a significantly smaller diameter than if natural circulation was used.

As for the equipment itself, the pumps have been virtually silent, reliable and practical, have compact sizes and do not require some special maintenance.

Any circulation pump from Wilo SE is an aggregate modern and productive, works for a long time and trouble-free. It should be noted that installing it with your own hands does not turn into some kind of complex and tightening operation. Yes, and the price of such equipment is much lower than the analogues presented in the domestic market.

Wide range of Wilo pumps - the ability to make a heating system effective

The domestic market offers an easy-to-have a huge selection of 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 technology, which the Wilo group really produces in abundance.

Among the most popular models of circulating pumps, the veil can be allocated:

Wilostar-RS. and model Wilostar-RSD- low-power, but at the same time reliable pumps that cost quite inexpensive. Ideal for various home heating systems. There is a built-in manual rotational speed switch, which allows to improve the efficiency of the technique. Suitable pumps from this series for heating rooms, with an area of \u200b\u200b200-750 sq.m;

Circulation pump

Wilo Stratos Eco. Effectively replaced the previous generation of circulation pumps, ideal for embedding in large heating systems, in which the power of the boiler installation exceeds 25 kW. These are electronic pumps, capacity adjustment and performance in which is made by means of a special system. Among the circulation pumps of this class for small cottages (more than 80% of existing heating systems). A feature can be called low electricity consumption and the possibility of working with the coolant even at a negative temperature;

Top-RL and model Top-S From the manufacturer, the circulation pumps designed specifically for buildings whose area exceeds 1400 square meters. meters. These are three-phase and dual pumps whose work is possible in high efficiency and performance modes;

Advantages of using pumps Wid in heating systems

Modern circulation pumps for Wilo heating systems are an excellent choice for any real estate object, be a small country cottage or an industrial enterprise.

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

Increase the efficiency of the flow of heat carrier in pipelines, better heat transfer even in the farthest corners of the heating system;
Reducing the consumption of fuel boilers and, as a result, the substantial economy of finance. Especially relevant for large boilers at manufacturing enterprises and other facilities;
Extending the deadlines for the uptime of the heating system.Circulation pumps are capable of creating quite high pressure in the pipeline, which eliminates the deposition of salt carrier salts . In turn, the blockage 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 pipeline lines) allow you to improve efficiency and performance, reduce costs, and exclude breakdowns.

Pumps from the famous German brand are surprisingly intended to be built into already existing and functioning heating systems (due to low weight and dimensions). They provide a rapid current of the coolant and its circulation on all radiators.

Nevertheless, their choice should be suitable with full responsibility, take into account the area of \u200b\u200bheated premises, as well as rubbing losses in the pipes.

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

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

Heating pumps for wet rotor

The technical characteristics presented in the pump catalog of the pump with a wet rotor allow them to work in autonomous heating with a pressure of up to 10 bar. The coolant is pumped due to the impeller fixed on the shaft (rotor). The peculiarity of this line is that the rotor should always be immersed in water (coolant), which performs two important functions: lubricant and cooling. This condition imposes certain setup requirements - the rotor must be in the horizontal plane. Performing this simple rule, you will not have to think about the repair of pumps for the pump (see).

The line is divided into two categories: with automatic power adjustment and with manual power adjustment. A total of 21 model of pumps with a wet rotor are represented. Their body is made of gray cast iron or bronze, steel rotor, plastic impeller, metallographic bearings. On the circuit, the unit can be installed by means of a threaded or flange compound. The last option is characteristic of Wilo industrial pumps.

Until now is the most popular and economical.

Before calculating the necessary thermal power.

In autonomous heating, it is necessary through a mixing unit that adjusts the temperature of the coolant.

Before the pump is necessarily a coarse filter (mud). It is necessary that the solid particles do not fall on the blade of the impeller and did not break it. The coolant always contains deposited salts or metals (scale), and the quality of water in the central networks is generally terrible.

The pump is attached to the contour by American - the detachable connection, which in turn is mounted on the ball valves. This will allow you to cut off the pump from the contour and remove the water from the entire system for repair or maintenance. . Without a supplied water supply - long.
