"Grundfos", pumps: characteristics and description

The market of equipment for water supply is represented by different brands that produce models for any needs. The Danish producer Grundfos is a specialized company in this niche. In its range you can find solutions for domestic needs, and powerful stations that are used in industry. As the users themselves note, the Grundfos pump is characterized by high-quality assembly, a well-thought-out design, and the availability of modern control systems. It remains only to make a choice in favor of an optimally suitable model for specific purposes.

Drainage pumps Unilift CC

One of the latest modifications in the family of drainage units is the Unilift CC pump. Among its main differences can be distinguished the presence in the construction of two nozzles, which allows the owner to independently control the direction of tapping of pumped water. The weight of the unit is 5 kg, so its operation is possible even in difficult for mounting conditions. The effectiveness of work with polluted media is also noted. Maintenance of problem liquids without structural damage is the strength of this Grundfos line. Unilift CC pumps can pump water with particulate matter up to 10 mm, but only without fibrous inclusions. The start-up of the equipment can be set to automatic mode. This means that at the moment of fixation by a float sensor to increase or decrease the liquid level, the device will independently decide whether to turn on or off the suction function. The maximum number of start-ups is 100 per hour. In order to increase the reliability of this pump, the developers used a high-strength composite and stainless steel in the structure, so sand and other inclusions do not adversely affect the internal surfaces of the unit.

Circulation pump Alpha2

The basic version of the Alpha plant is considered one of the best in the general segment of circular pumps. Today, the new version of Alpha2 is also gaining popularity, the list of advantages of which includes energy efficiency, resistance to damage and increased reliability in all conditions. By the way, the power consumption of this model in standby mode is only 800 kW. As practice shows, with such supply, the circulation pump "Grundfos" is capable of providing a head up to 8 m, which allows it to service private households with an area of up to 300 m ² . In the installation, there are also implemented protective systems, among them - automatic restart in case of a "dry" course. In general, the developers paid special attention to the starting characteristics. So, even after a long standby mode, the unit itself starts at the beginning of the heating season.

Downhole pump MP 1

Widely represented in the assortment of the Danish company and well pumps, intended also for taking groundwater samples. These include the model MP 1, which allows you to perform procedures for cleaning wells, as well as pumping out contaminated media. Compact pumps for the Grundfos well of this series are suitable for operation at a depth of up to 80 m. The diameter of the created well can be only 2 inches. The unit is characterized by balanced technical and operational indicators. For example, the plant's capacity is 2.5 m ³ / h at a voltage of 220 V.

Submersible pumps DPK and DWK

The basis of the family of submersible aggregates is formed by two series - DPK and DWK. Both versions are designed for drainage and drainage operations. The DWK version has an upper discharge nozzle, and the filter is installed on the suction line - this design is considered optimal for temporary operation. The DPK model is equipped with a lateral discharge nozzle, so that it can be installed on a ring base or with a pipe automatic coupler. Therefore, the submersible "Grundfos" pump in the DPK version is advisable to use in the constant operation mode, which requires a fixed installation. In both cases, the units provide a capacity of about 430 m ³ / h, giving a head of 102 m. Based on the results of operation, users characterize models as wear-resistant, efficient in pumping and flexible in installation operations.

Self-priming unit JP

If you need a universal device for household work in a private house or garden, the JP model is suitable. This is a small-sized "Grundfos" pump, the characteristics of which are optimal for individual application - the productivity reaches 4.5 m ³ / h, and the head - about 50 m. There are two modifications of the unit. The basic version represents a block construction with a lid, a lantern and a slab-base made of composite materials. The second option provides the same device, but the main working parts are made of stainless steel.

To implement the functions of water supply with small requirements for pressure potential, the manufacturer recommends supplementing the installation with a Grundfos pressure regulator. Pumps in this configuration can provide a steady rise of water from an 8-meter depth at a pressure of 6 Bar.

Sump pump SPO

Another representative of the residential segment, focused specifically on the use in cottages and country houses. The SPO design is advantageously made of corrosion-resistant components, and high-quality stainless steel was used in the manufacture of the flow passage and the guide chamber chamber. The model provides feed to 6.5 m ³ / h, maintaining a stable head up to 75 m. In terms of application, it is rather a universal Grundfos pump. Bore water intake, for example, is possible at points with a diameter of 5-6 inches. But mostly these models are used to collect water from precipitation, maintain pressure in water supply systems and as submersible plants in the irrigation of gardens and gardens. The special features of the unit include a double shaft seal at the ends, the possibility of using a float switch and, in general, a wide range of mounting possibilities.

Hydro MPC Pump Station

In addition to household appliances, the manufacturer also produces reliable equipment for commercial and industrial facilities. High-tech representatives of this group include the Hydro MPC pressurized station. The unit provides water supply in volumes of 1080 m ³ / h, and the head reaches 155 m. The maximum pressure level in the basic version is 16 bar, and in special versions it is increased to 25 bar.

Separately, it is worth noting the management system, which is implemented using the special technology Grundfos. Pumps in the MPC series can operate automatically and in accordance with the settings made through the control panel with the controller. Intelligent system allows you to quickly adapt the station to the needs of the user, which ultimately ensures the operation in the optimal performance mode with minimal energy consumption.

Conclusion

Grundfos is rightly referred to the leaders in the pumping equipment market. A direct confirmation of this is the variety of models, each of which has optimal performance in terms of performing direct tasks. Balanced performance indicators, wide functionality, use of high-strength materials in the design and implementation of the latest management systems - these are the main advantages that characterize the products of Grundfos. Pumps also develop in the direction of energy saving. For example, automation systems allow you to adjust the operating parameters of the units to the most advantageous operating mode without the owner's involvement. In this case, the automation chooses the optimal ratio between the capacity with the volumes of pumped water and energy consumption.
