Wilo is a circulation pump. The lineup, characteristics, description and reviews
The range of circulating 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 become an indispensable condition for equipping households. True, the higher the load on the engineering system, the more stringent and the requirements for its constituent parts. Not every manufacturer can offer both a durable and a productive station for pumping liquids. Among the exceptions, we can mention Wilo, whose circulation pump is represented in several variations. At the same time, all models are distinguished by well thought-out ergonomics and the availability of modern controls.
Varieties of Wilo pumps
The manufacturer solves the problem of weak 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 always be 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 regular maintenance.
The concept of the dry rotor from Wilo is fundamentally different. The circulating pump in this version has a rotor separated from the working part. A special O-ring separates the functional parts, so it becomes necessary to periodically check the engine and its components for the presence of suspended particles. Besides the nuances of maintenance, there are other differences between the two types of circulation pumps. Models that assume the wetting of the shaft, in the course of work, do not make much noise, but the alternative version wins due to high productivity.
Characteristics of Wilo circulation pumps
Since much of the use of pumps depends on the connection parameters, the voltage and frequency of the network must first be calculated. For models of this brand is characterized by support voltage of 230 V and a frequency range of 50-60 Hz. Further, the indicator of the working pressure 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 ruler, for example, provides 16 bar. It should also take into account indicators of throughput and pressure. As for the volume of consumption, it leaves an average of 3-5 m 3 / h. The power (from the point of view of the head) varies on average from 4 to 7 m. In each case it is important not to forget the parameters of the circuit, along 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 threaded connection type. To adjust the power indicators in the design, it is possible to set three speed modes. Use this unit is possible for heating systems, and in cold water supply systems, as well as in the composition with climatic equipment. With regard to direct installation and maintenance, the Wilo Star circulation pump is one of the most profitable solutions. Its simple hydraulic device does not require the use of special seals for the shaft and protective relays. Since the pumped coolant independently lubricates the slide bearings and provides cooling of the rotor element, it can be said about the high degree of autonomy of this unit.
Circulation pump Wilo Top-S
In a way, this is a classic execution of models of this type that combines traditional design and modern automatic systems. In this case, the threaded connection type is interleaved with flange elements, which adds flexibility to the device configuration in terms of mounting. Use such models in the same heating, conditioning and cooling systems. Depending on the modification, it is also possible to introduce the unit into industrial communication systems. Among the technological advantages can be noted the brand management systems Wilo. The circulation pump in the Top-S series has a built-in electronic type trip system. This applies to both three-phase and single-phase installations. External control is realized 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, which can be used as a circulating unit. Such models, in particular, are used in equipping dwelling houses, as well as industrial infrastructure and agriculture. The working medium can be both cold and hot water. Since the circulation pump for heating Wilo in the BAC version does not provide the possibility of passive lubrication by the working medium, it should be initially prepared for regular maintenance. However, if it is a question of pumping clean water, the list of such measures can be limited to testing of connections and technical and operational parameters.
Reviews of pumps Wilo
Owners of houses in which the equipment of this manufacturer is responsible for coolant circulation and water supply, note the reliability and durability of the equipment. Mechanisms work reliably for a long time, without requiring special technical measures. But there is also a criticism that Wilo circulating pumps receive. The price of 6-10 thousand rubles. For base modifications, causes negative responses. 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. First, the manufacturer pays a lot of attention to specialized structural designs, releasing to the market and quite original modifications. Secondly, the circulation pump for Wilo heating is characterized by a wide supply of electronic systems. The development of these two areas allows designers to open new boundaries in the technical organization of the communication infrastructure of the modern house. For example, the introduction of automatic control systems makes it possible to optimize the management of the coolant. As a result, the engineering network becomes more economical and at the same time more productive.
