Pumping stations are optimized equipment for supplying water from wells, reservoirs and other hydrological sources. Depending on the needs, a model with specific characteristics is selected. The line of the Danish manufacturer includes devices capable of operating at a depth of up to 8 m. In addition, the Grundfos pumping station facilitates the user's tasks in terms of control through automated control systems. Moreover, automation is not only responsible for the direct regulation of the operating modes of the equipment, but also protects the "stuffing" from clogging and overheating.
General information about Grundfos pumping stations
Developers offer comprehensive solutions to water supply problems both in private households and at industrial facilities. The entry level of installations of this type is represented by compact, but at the same time productive units of the UPS and MQ lines. From the representatives of these series, you can choose a country pump, which will provide a stable water supply at minimal cost. Even "younger" models are provided with specialcontrollers that allow you to control the water intake process without the participation of the owner.
More technologically advanced industrial stations offer a different level of engineering and communication needs. In particular, the Grundfos pumping station in this segment is represented by equipment that allows solving specialized tasks. This can be water treatment with multi-stage purification steps, and maintenance of sewer systems, as well as the traditional supply of enterprises with a hydrological resource.
UPS Family Stations
In this case, we consider a family of domestic circulation units that provide hot and cold water flow. Due to their modest size, representatives of this series can be installed in the most difficult places to locate, occupy a minimum of space, including for laying pipeline communications. At the same time, small sizes do not at all mean low power and, all the more, fragility of the structure. The Grundfos UPS body is made of cast iron, and the impeller is made of a heat-resistant composite that is not subject to corrosive processes. Also, such models are suitable for operation in conditions of increased temperature exposure - for example, in one- or two-pipe heating systems. As for performance, for example, modification 25-80 has a power of 250 W, supplying water in volumes of about 125 l / min. The pressure in this case is 10 Atm.
Station GrundfosMQ
Representatives of this line are suitable for domestic use in the private sector, and to meet the needs of industrial facilities. Thus, the MQ 3-35 version is a multi-stage unit designed to increase pressure in water supply systems. In a minute, this device pumps an average of 53 liters of water. At the same time, the quality of the serviced environment does not have to be perfectly clean. The design allows you to safely work with liquids that contain sand particles. The advantages of Grundfos MQ units include modern control, which is implemented through a special panel. Light indicators help the operator to control the process, and if the level of contamination exceeds the permissible values, automation without third-party commands will stop the pumping function. The power of this unit is already 850 W, and the maximum water rise is possible by 35 m. There are also modifications with a rise to a height of about 45-50 m, which allows the use of models in public utilities when servicing facilities that require water supply.
JP Stations
JP units are represented by autonomous stations, which include a capacious membrane tank. Such units are also suitable for private use on large farms for the purpose of irrigating plots, and for maintaining pressure in water supply systems. Again, the integrated control relay allows you to regulate the pump function, activating it when the pressure level drops and turning off the device when it rises. One of the lastdevelopment of the series is a modification of the Grundfos Basic 3 PT, equipped with a 19 l tank, a pressure gauge for monitoring pressure indicators and overheat protection.
PUST Sewer Station
To manage industrial wastewater, it is not advisable to use traditional pumping units, even with increased operational capabilities. For such needs, special stations are suitable, an example of which is the PUST installation, designed to equip the sewer system. A feature of the model is the integration of the grinder, represented by the SEG AutoAdapt device. This is a proprietary development of the company, which is designed specifically for pressure sewers. In addition, the Grundfos pumping station in the PUST version is distinguished by a control system with an anti-pollution function. The operator can set up an operating mode with automatic flushing and reverse operation. In this format of maintenance, the control system eliminates the risk of equipment failure as a result of clogging with fibrous components and solid particles. Also, the advantages of this system include the ability to remotely control the system via a network using a SCADA interface.
How to choose the best option?
Grundfos has significantly expanded the capabilities of pumping equipment, allowing you to accurately select systems for specific needs. When choosing a classic household station for irrigation, it is quite possible to confine ourselves to the analysis of basic operational parameters. For example, for watering a small gardenthere will be a rather modest power representative of the UPS series. If pumping equipment is required to fully ensure the water supply system, then you can opt for the JP and MQ units, but before that, compare the characteristics of specific modifications with the requirements for the system. The principles for choosing industrial stations are somewhat different. Such installations have a complex principle of operation, for the control of which it is necessary to use appropriate control systems in the form of relays and multifunctional panels.
How much does Grundfos pumping equipment cost?
The cost of different models differs depending on the technical characteristics, functionality, the presence of automated systems, etc. The company has an advantage over competitors precisely in that it has a balanced approach to pricing, allowing users with different incomes to choose the optimal model. In particular, the Grundfos household pumping station, the price of which varies between 10-12 thousand rubles, is suitable for operation on a small plot of land. The manufacturer's assortment includes many options for irrigation, which are provided with good functionality. The middle segment is already available for 20-30 thousand rubles. These are models that have increased technical and operational capabilities and a modern composite is used in the design. One of the most expensive offers is the Grundfos sewage pumping station, the price of which is about 100 thousand rubles.
Conclusion
Danish designers are working not only to improve control systems and technical indicators. They also care about the reliability and durability of the equipment, carefully approaching the selection of materials. As a result, the Grundfos pumping station receives high-strength structures that contain a productive power filling. Such units are not afraid of external physical influences and precipitation. Metal elements have special protective coatings that prevent negative corrosion processes. In turn, composites and plastics cause a small mass of units, which is convenient for transportation and installation of equipment.
