The range of circulation pumps in 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 a productive liquid pumping station. Among the exceptions, Wilo is a company whose circulation pump is available in several variations. At the same time, all models are distinguished by well-thought-out ergonomics and the availability of modern controls.
Varieties of pumps Wilo
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 eliminates the need for regular maintenance.
The concept of a dry rotor from Wilo is fundamentally different. The circulation pump in this design has a rotor separated from the working part. A special o-ring separates the functional parts, so there is a need for periodic inspection of 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 wetting the shaft practically do not make noise during operation, but the alternative version wins due to high performance.
Characteristics of Wilo circulation pulsers
Since much in the use of pumps depends on the connection parameters, the main thing is to calculate the voltage and frequency of the network. Models of this brand are characterized by voltage support of 230 V and a frequency range of 50-60 Hz. Further, an indicator of working pressure is taken into account, on which, in principle, the ability to maintain 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 of Wilo equipment. The circulation pump in the special version of the Top range, for example, provides 16 Bar. Throughput and pressure ratings should also be taken into account. As for the flow rate, it leaves an average of 3-5 m 3 / h. Power (in terms of pressure) 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 a threaded type of connection. To configure power indicators, the design provides the ability to set three speed modes. It is possible to use this unit both for heating systems, and in cold water supply complexes, as well as in combination with climatic equipment. With regard to direct installation and maintenance, the circulation pump Wilo Star is one of the most profitable solutions. Its simple hydraulic device does not require the use of special shaft seals and protective relays. Since the pumped coolant independently lubricates the sliding bearings and provides cooling of the rotor element, we can talk about a high degree of autonomy of this unit.
Wilo Top-S circulation pulser
In a way, this is a classic performance of this type of model, which combines a traditional design and modern automatic systems. In this case, the threaded type of connection is interspersed with flange elements, which adds flexibility to the device configuration in terms of installation. Use such models in the same heating, air conditioning and cooling systems. Depending on the modification, the introduction of the unit into industrial communication complexes is also allowed. Among 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 three-phase and single-phase installations. External control is implemented through a special module equipped with light indication and alarm devices.
BAC family
This line represents dry rotor pumps. This is a single-stage centrifugal unit, which can be used as circulating. 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 circulation pump for heating Wilo 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 measures may be limited to checking the connections and technical and operational parameters.
Wilo Pump Reviews
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. The mechanisms work flawlessly for a long time, without requiring special technical measures. But there is also the criticism that Wilo circulation pumps get. The price of 6-10 thousand rubles. for basic modifications, causes negative feedback. However, well-known brands 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 structural designs, launching quite original modifications on the market. Secondly, the circulation pulser for heating Wilo is characterized by a wide range of electronic systems. The development of these two areas allows designers to open new boundaries in the technical organization of the communication infrastructure of a modern house. For example, the introduction of automatic control systems allows you to optimize the management of the coolant. As a result, the engineering network is becoming more economical and at the same time more productive.
