The range of circulation pumps on the market is more focused on the needs of private users. The introduction of reliable and functional equipment in the organization of communication infrastructure has long been a prerequisite in equipping households. True, the higher the load on the engineering system, the more stringent the requirements for its components. Not every manufacturer can offer both a durable and productive station for pumping liquids at the same time. Among the exceptions, Wilo can be noted, the circulation pump of which is presented in several variations. At the same time, all models are distinguished by well-thought-out ergonomics and the presence of modern controls.
Varieties of Wilo pumps
The manufacturer solves the problem of poor circulation of the coolant in two ways - pumps with a "wet" and "dry" rotor. The design of the units of the first group assumes that the working shaft will be constantly in a liquid medium. That is, during operation, the coolant lubricates the functional elements of the device, which saves the user from the need for regularmaintenance.
The dry rotor concept is fundamentally different from Wilo. The circulation pump in this design has a rotor separated from the working part. A special sealing ring separates the functional parts, so it becomes necessary to periodically check the engine and its components for the presence of suspended particles. In addition to the nuances of maintenance, there are other differences between the two types of circulation pumps. Models that involve shaft wetting are practically silent during operation, but the alternative version wins due to high performance.
Characteristics of Wilo circulation pumps
Since much of the use of pumps depends on the connection parameters, the mains voltage and frequency should be calculated first. Models of this brand are characterized by voltage support of 230 V and a frequency range of 50-60 Hz. Next, the operating pressure indicator is taken into account, on which, in principle, the possibility of maintaining circulation at the proper level will depend. The manufacturer produces models with a pressure level of 6 to 10 bar. However, there are other indicators for Wilo equipment. The circulation pump in the special version of the Top range, for example, provides 16 bar. You should also take into account the indicators of throughput and pressure force. As for the flow rate, it leaves an average of 3-5 m3/h. The power (in terms of head) varies on average from 4 to 7 m. In each case, it is important not toforget the parameters of the circuit through which the coolant will circulate, but these data are selected individually, depending on the needs of the house.
Star Series
This family represents models with a "wet" rotor and a threaded type of connection. To adjust the power indicators in the design, it is possible to set three speed modes. This unit can be used for heating systems, and in cold water supply complexes, as well as as part of climate control equipment. With regard to direct installation and maintenance, the Wilo Star circulation pump is one of the most cost-effective solutions. Its simple hydraulic design does not require the use of special shaft seals and protective relays. Since the pumped coolant independently lubricates the plain bearings and provides cooling for the rotor element, we can speak of a high degree of autonomy of this unit.
Circulation pump Wilo Top-S
In a way, this is a classic version of this type of model, which combines traditional construction and modern automatic systems. In this case, the threaded type of connection is interspersed with flange elements, which adds flexibility to the configuration of the device in terms of installation. Such models are used in the same heating, air conditioning and cooling systems. Depending on the modification, it is also possible to introduce the unit intoindustrial communication complexes. Among the technological advantages, Wilo's proprietary control systems can be noted. The circulation pump in the Top-S series has a built-in electronic type shutdown system. This applies to both three-phase and single-phase installations. External control is implemented through a special module equipped with light indication and signaling devices.
BAC Family
This line represents pumps operating with a "dry" rotor. This is a single-stage centrifugal unit that can be used as a circulation unit. Such models, in particular, are used in equipping residential buildings, as well as industrial infrastructure and agriculture. Both cold and hot water can act as a working medium. Since the Wilo circulation pump for heating in the BAC version does not provide for the possibility of passive lubrication with a working medium, you should initially prepare for regular maintenance. True, if we are talking about pumping clean water, then the list of such activities may be limited to checking connections and technical and operational parameters.
Reviews about Wilo pumps
Owners of houses in which the equipment of this manufacturer is responsible for the circulation of the coolant and water supply note the reliability and durability of the equipment. Mechanisms work flawlessly for a long time, without requiring special technical measures. But there is also criticism that Wilo circulation pumps receive. The price is 6-10 thousand rubles.rub. for basic modifications, causes negative feedback. However, well-known brands also produce more expensive products of the same class.
Conclusion
The company's approach to the development of pumping equipment has several distinctive features. Firstly, the manufacturer pays a lot of attention to specialized design designs, releasing quite original modifications to the market. Secondly, the Wilo heating circulation pump is distinguished by a wide range of electronic systems. The development of these two directions allows designers to open new frontiers in the technical organization of the communication infrastructure of a modern home. For example, the introduction of automatic control systems makes it possible to optimize the control of the coolant. As a result, the engineering network becomes more economical and at the same time more productive.
