Operating instructions for the wilo circulation pump. Forced circulation with a Wilo pump for home heating systems. Placement and installation rules

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 to replace natural circulation in heating systems, forced comes, 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.

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

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

With 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 before buying specific model It will not be superfluous to consult with experts. 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;

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 on manufacturing enterprises and other objects;
3. Extended uptime heating system. Circulation pumps 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 the 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 natural way according to the law of gravity, are found less and less, and only where small area heated with a single-circuit boiler.

Forced circulation equipment

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

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 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 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. Versatility Wilo equipment due to double-sided cable connection and complete set with a combined flange 6/10 bar (for models with an inner 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

4 Description of pumps and accessories

4.1 Description of wet running pumps

In wet running pumps, all moving parts, including the motor rotor, are flushed with liquid. Shaft seals are not required. The liquid lubricates the plain bearings, cools them and the rotor.

The twin pumps are identical and installed in the same housing. They are equipped with an integrated changeover valve. Each pump can work autonomously, as well as both - simultaneously. Twin pumps can be used in two different versions:

Working and standby pump (in case of failure of the main pump, the standby pump is put into operation);

Main and peak pump (the latter is activated additionally at peak loads).

In this case, both pumps can differ in installed capacities. The twin pump plant can therefore be adjusted to the individual production situation.

Pump motor:

For single-phase current 220 V: special motor only for operation with single-phase current;

For 3-phase current 380 V: special motor for three-phase current only. The motor cannot be connected according to the Steinmetz scheme.

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 motor protection. Overload current cannot damage the motor and cause it to stall.

The motors of all other pumps are equipped with contact winding protection (WSK). In case of impermissible overheating of the motor, protection via a switch, eg SK 602/622 or C-SK (accessories), switches off the motor. After the motor has cooled down, the pump can be switched on again. A circuit breaker (SK 602, SK 622 or C-SK) is highly recommended for motor protection. When using WILO switching devices for automatic regulation, there is no need for special switches, since they are already integrated in the switching devices.

To control the twin pump, an automatically operating switching device S2R3D is required. The motor protection switch is also integrated in the switching device.
Speed ​​changeover:

All pumps have a 4-stage manual switch (on the terminal box) . At the lowest stage, the number of revolutions is reduced by 40-70% of the maximum. Energy consumption will be reduced by 50%.

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

Pumps with single-phase current motors with a power of P 2 less than 75 W can also be connected to a two-stage automatic switch (S2R-h, timer).

On pumps with a three-phase current motor, the speed is switched over by switching the 4-stage plug on the terminal box. In addition, it is possible to connect a 2/4-stage automatic switch (fig. 1b, pos. 1).
Devices automatic control and adjustments:

Devices for automatic control and adjustment of pump power depending on hydraulic needs are available in the WILO program.

5 Assembly and installation

5.1 Mounting

The installation should be carried out after the completion of all welding and locksmith work and flushing of the pipe system. Contaminants can impair pump performance.

- The pumps must be installed in easily accessible locations so that later inspection or replacement of the pump can be easily carried out.

It is recommended to install stop valves before and after the pump. This eliminates the need to refill the system when replacing the pump. The fittings must be mounted in such a way that, in case of leaks, water does not get on the electric motor and the terminal box.

Installing a pump in an open system expansion tank always make after the place of its connection.

Installation should be carried out without mechanical stress and only with a horizontally located pump shaft; observe the installation position as shown in figure 2.

The arrow on the pump body shows the direction of flow.

The motor terminal box must not point downwards as water can easily get into it. Rotate the motor housing if necessary.

ATTENTION!
Do not damage gaskets.

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

For pumps equipped with a plug-in module, the module must be free of air.

5.2 Electrical connection

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

The electrical connection must be made strictly according to the instructions with a plug connection or an all-pole switch with a minimum contact distance of 3mm.

Sufficiently sized cable must be used to protect against water ingress and reduce stress on the packing nut.

When installing pumps in systems with water temperatures above 90°C, a temperature-resistant cable must be used, which must under no circumstances come into contact with the pipeline or with the pump housing.

Check the type of current and voltage in the network and compare with the data in the table on the pump.

- Observe the type data of the pumps.

- Network connection and connection of the SK 602/622 circuit breaker according to the diagrams (Fig. 3a to 3e) should be performed (see also 1.22 and 4.1):

3a: 220V non-blocking motor.

3b: 380V non-blocking motor.

3s: 220 V, with WSK (motor winding thermal protection contacts).

3d: 380 V, with WSK.

3e: when installing a C-SK switching plug, circuit 3d is replaced by 3e.

Perform grounding.

When using other protection devices, terminals 15 and 10 (WSK) must be connected to the motor control circuit (max. 250 V) together with an anti-reclosing device. Then the pump on all four stages is protected.

ATTENTION!

- The setting of the thermal switch must be carried out according to the corresponding maximum current for the selected speed stage (see type table).

When connecting circuit breakers, observe the relevant installation and operating instructions.
6 Commissioning

6.1 Filling the system and venting

Fill the system properly. The removal of air from the system occurs independently after a short-term activation of the pump. Short-term dry running does not harm the pump. If direct venting of the pump is required, this can be done as follows:

turn off the pump;

Close the shut-off valve at the outlet;

Carefully unscrew the bleed screw (Fig. 4).

- Carefully push the pump shaft back;

Protect electrical parts from liquid and vapour;

Turn on the pump;

After 15 ..... 30 seconds of operation, turn off the pump and tighten the air release screw;

Open the fitting again and turn on the pump.

ATTENTION!
If the screw port is open, depending on the pressure, the pump may block.

6.2 Adjustment

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

Before checking the direction of rotation, unscrew the screw on the front of the motor. By briefly switching on, check whether the direction of rotation of the shaft matches the arrow on the plate. If the direction of rotation is wrong, change 2 phases.

- Switching the number of revolutions:

Single-phase current motors: switching between the 4 speed stages is done manually using the motor terminal box switch. Three-phase current motors: switching between the 4 speed stages is done manually by switching the 4-stage plug on the motor terminal box. Loosen the central bolt and set the 4-stage plug with arrow to the desired speed level. Tighten the central screw again.

7 Service

The pumps are maintenance free.
8 Faults, causes and remedies

Heating pumps Glandless forks

Technical characteristics presented in the catalog of Vilo pumps with wet rotor, 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 line is divided into two categories: automatic adjustment power and with manual power adjustment. 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 industrial pumps Wilo.

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 filter must be installed in front of the pump coarse cleaning(sump). 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 water quality in central networks 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.
