The pump manufacturer Grundfos offers customers a wide range of pumping units for different needs. The line includes both technological solutions for water supply and sewerage installations, 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 perform both an auxiliary and a main function. The versatility of the use of such units is also due to the special interest in them on the part of users.
Main characteristics of circulation models
Like all transfer pumping equipment, models of this type are primarily characterized by throughput. In basic versions, Grundfos circulation pumps provide a throughput of about 3 m3/hour. Larger units can serve 11 m3/hour. The 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 these limits, but they are usually used in commercial orindustrial purposes.
An important working parameter is pressure. The stability of water supply depends on how high this indicator is. In the initial category, Grundfos circulation pumps are presented, 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.
Magna Series
The units of this series have been designed to enable circulation of the carrier 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 heating circulation pump performs 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 also important to consider compliance with the requirements of communication from the power characteristics of the pump. Thanks to a pressure of 16 bar, such installations can be used in large-area houses with a high contour length. There are many features that Grundfos circulation pumps of this line have. In particular, many note the benefit of the display system, which in some versions is represented by several light alert fields.
UPS Series
Thisthe family represents three-speed models, which are available in two basic modifications - 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 the motor into one block, which made it possible to reduce the dimensions of the structure. Another feature is also interesting, which compares favorably with the Grundfos UPS circulation pump in all versions. This is the use of a serviced fluid as a lubricant, which significantly increases the durability of systems of this type. It should be noted that representatives of this series are suitable not only for traditional heating system configurations. The UPS can be used to supply water heaters, heat pump systems, geothermal utilities, and floor heating.
Alpha models
The features of this line include the ability to work with climate equipment. The capacities of the units are based on classic circulation pumps, but the improvements made have significantly improved the operating parameters and expanded the range of applications. In the basic configuration, the Grundfos Alpha series circulation pump provides a throughput of 3 m3/h, and the head of the unit reaches 6 m. These are rather average characteristics against the background of even traditional designs of this type, and The strong point of the model 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 of automaticmaking settings. It is enough to integrate the pump into the communication circuit, and then he will calculate the optimal performance.
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 pumps have modest performance figures, their other parameters provide many advantages - low noise level, compactness, durability and minimal energy consumption requirements. As for operational capabilities, the Grundfos Comfort circulation pumps provide a flow rate within 0.6 m3/h and a pressure capacity of 120 cm. At the same time, the equipment is equipped with the latest automatic control systems and devices indication, which also allows you to count on significant energy savings due to the optimization of performance.
Conclusion
The main purpose of circulation pumps is to maintain the efficiency of engineering systems. This explains the prevalence of such equipment among private consumers who provide equipment for country houses and cottages. 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 evaluates the water needs of the household, after which it launches the programoptimization. As a result, the communication network adapts to the optimum flow characteristics of the liquids, which contributes to energy savings. Of course, the pump user can make any adjustments to the operating mode.
