The manufacturer of pumps "Grundfos" offers its customers an extensive range of pumping units for various needs. The range includes technological solutions for water supply, and sewage systems, as well as special modifications for deep work. At the same time, the Grundfos circulation pumps represent the basis of the model range, which during operation can fulfill both the auxiliary and the main function. The universality of the use of such units is also due to the special interest in them from users.
Key Features of Circulation Models
Like all pumping pumping equipment, models of this type are primarily characterized by throughput. In basic versions, Grundfos circulation pumps provide a throughput of about 3 m 3 / h. More powerful plants can serve 11 m 3 / h. A specific indicator is determined by the power of the power plant, which varies from 25 to 280 watts. However, there are models whose potential goes beyond this framework, but they are usually used for commercial or industrial purposes.
An important working parameter is the pressure. The stability of water supply depends on how high this indicator is. The Grundfos circulation pumps are presented in the initial category, the characteristics of which, in terms of pressure, are expressed as 4 m, but already in the middle segment this value rises to 10 m. Now it’s worth to take a closer look at the models of circulating units of this brand.
Models of the Magna series
Units of this series were designed to provide the possibility of circulation of the medium in heating systems with variable flow. The flexibility of equipping the house with such models, in terms of location, allows the user to optimize energy costs. The main task that the Grundfos circulation pump for heating in this series is to regulate the parameters of water circulation. It is under this function that the design of the unit with its controls is oriented.
But it is important to take into account the compliance with communication requirements from the power characteristics of the pump. Due to the pressure of 16 Bar, such installations can be used in large-area houses with a high contour length. There are many features that circulation pumps "Grundfos" of this line possess. In particular, many note the benefit of the display system, which in some versions is represented by several fields of light notification.
UPS Series
This family represents three-speed models, which are available in two main versions - at 50 and 60 Hz. An example of such units demonstrates the manufacturability of the design and a thoughtful approach to performance. The developers combined the pump and engine in one unit, which allowed to reduce the dimensions of the structure. Another feature is interesting, which compares favorably with the Grundfos UPS circulation pump in all versions. This is the use of the serviced fluid as a lubricant, which significantly increases the durability of this type of system. It should be noted that representatives of this series are suitable not only for traditional configurations of the heating system. UPS can be equipped with water heaters, heat pump systems, geothermal communications, as well as floor heating.
Alpha Models
The features of this line include the ability to work with climate equipment. The power of the units is based on classic circulation pumps, but the improvements made significantly improved 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 head reaches 6 m. These are pretty average characteristics compared to even traditional designs of this type, and the model’s strength is expressed by the temperature of the pumped medium, which can vary from 2 to 110 ° C. The latest modifications are also distinguished by the unique ability to automatically perform settings. It is enough to integrate the pump into the communication circuit, and then he will calculate the optimal performance indicators.
Comfort Series
If you need a small unit to perform low-volume pumping in domestic conditions, then you should refer to the Comfort line. Since this type of pump has modest performance indicators, its other parameters provide many advantages - low noise, compactness, durability and minimal energy requirements. With regard to operational capabilities, the Grundfos Comfort circulation pulsers provide a flow rate of 0.6 m 3 / h and a pressure head of 120 cm. Moreover, the equipment is equipped with the latest automatic control systems and indicating devices, which also allows for significant energy savings by optimizing performance.
Conclusion
The main purpose of circulation pumps is to maintain the operability of engineering systems. This explains the prevalence of such equipment among private consumers, providing country houses and cottages with appliances. For this reason, the Grundfos circulation pump in many of its versions is designed with ergonomics and ease of use in mind. Perhaps the most technologically advanced solution in this regard is the Alpha pump. In the first days of operation, the unit assesses the household's water needs, and then launches an optimization program. As a result, the communication network adapts to the optimal flow characteristics of liquids, which contributes to energy savings. Of course, the user of the pump can make any adjustments to the operating mode.
