Circulation pumps "Grundfos": review, characteristics, photo

The pump manufacturer "Grundfos" offers its clients a wide range of pumping units for different needs. The line also includes technological solutions for water supply, sewerage systems, as well as special modifications for deep work. At the same time, Grundfos circulating pumps represent the basis of the model range, which, during operation, can perform both auxiliary and basic functions. The universality of the use of such units is due to the special interest to them from the users.

Basic characteristics of circulating models

Like all pumping equipment, models of this type are primarily characterized by capacity. In basic versions, circulating pumps Grundfos provide a capacity of about 3 m ³ / h. More powerful installations can serve 11 m ³ / hour. The specific figure is determined by the power of the power plant, which varies from 25 to 280 watts. However, there are also models whose potential goes beyond these limits, but they are usually used for commercial or industrial purposes.

An important working parameter is the head. The stability of water supply depends on how high this indicator is. In the initial category, the Grundfos circulation pumps are presented, the characteristics of which, in terms of head, are 4 m, but already in the middle segment this value rises to 10 m. Now it is worth to learn more about the models of the circulation units of this brand.

Models of the "Magna" series

The units of this series were designed to allow carrier circulation in heating systems with variable flow rates. The flexibility of equipping the house with such models, in terms of location, allows the user to optimize energy costs. The main task of the Grundfos circulation pump in this series is to regulate the water circulation parameters. It is for this function that the design of the unit with its control elements is oriented.

But it is important to consider and meet the requirements of communication from the power characteristics of the pump. Due to the pressure in the 16 bar, such installations can be used in large-area houses with a high contour length. There are many features that circulating pumps Grundfos of this line possess. In particular, many note the benefits of the display system, which in some versions is represented by several fields of light warning.

UPS series

This family represents three-speed models, which are available in two main modifications - at 50 and 60 Hz. An example of such units demonstrates the technological design and a thoughtful approach to performance. Developers connected the pump and the engine in one unit, which allowed to reduce the overall dimensions of the structure. Another interesting feature is the advantage of the Grundfos UPS circulating pump in all versions. This is the use of serviced fluid as a lubricant, which greatly increases the durability of systems of this type. It should be noted that the representatives of this series are suitable not only for traditional heating system configurations. The UPS unit can be supplied with water heaters, heat pump systems, geothermal communications, as well as heating floor coverings.

Models Alpha

The features of this line include the possibility of working with climate equipment. The capacities of the units are based on classical circulating pumps, but the improvements made markedly improved the operating parameters and expanded the range of applications. In the basic configuration, the Grundfos circulation pump of the Alpha series provides a throughput of 3 m ³ / h, and the installation pressure reaches 6 m. These are fairly average characteristics against the background of even traditional designs of this type, and the strong side of the model is expressed by the temperature of the pumped medium, which can Vary from 2 to 110 ° C. The newest modifications differ and the unique ability to automatically perform settings. It is enough to integrate the pump into the communication scheme, and then he will calculate the optimal performance.

Comfort series

If a small unit is required to perform low-volume pumping in a domestic environment, then you should refer to the "Comfort" line. Since pumps of this type have a modest performance, their other parameters provide many advantages - low noise, compactness, durability and minimum energy consumption requirements. With regard to the operational capabilities, the circulation pumps Grundfos Comfort provide a flow rate of 0.6 m ³ / h and a power output of 120 cm. The equipment is supplied with the latest automatic control systems and indicating instruments, which also allows for significant energy savings By optimizing performance.

Conclusion

The main purpose of circulating pumps is to maintain the operability of engineering systems. This explains the prevalence of such equipment among private consumers, providing technology for country houses and villas. For this reason, the Grundfos circulation pump in many of its versions is designed with the expectation of ergonomics and ease of use. Perhaps the most technologically advanced solution in this regard is the Alpha pump. In the first days of operation, the unit evaluates the needs of homeownership in water, and then launches the optimization program. As a result, the communication network is adjusted for optimal fluid flow characteristics, which helps to save energy resources. Of course, the pump user can make any adjustments to the operating mode.
