The market for water supply equipment is represented by different brands that produce models for any needs. Danish manufacturer Grundfos is a specialized company in this niche. In its assortment you can find solutions for domestic needs, and powerful stations that are used in industry. As users themselves note, the Grundfos pump is notable for its high-quality assembly, well-thought-out design, as well as the presence of modern control systems. It remains only to make a choice in favor of an optimally suitable model for specific purposes.
Unilift CC Drainage Pumps
One of the latest modifications in the drainage unit family is the Unilift CC pump. Among its main differences, the presence of two nozzles in the design can be distinguished, which allows the owner to independently control the direction of the discharge of pumped water. The mass of the unit is 5 kg, so its operation is possible even in difficult installation conditions. Efficiency in work with polluted environments is also noted. Serving problematic fluids without structural damage is the strength of this Grundfos line. Unilift CC pumps can pump water with solid particles up to 10 mm in fraction, but only without fibrous impurities. Starting equipment can be set to automatic mode. This means that at the moment the float sensor fixes the increase or decrease in the liquid level, the device will independently decide whether to enable or disable the suction function. The maximum number of start-up stops is 100 per hour. In order to increase the reliability of this pump, the developers used high-strength composite and stainless steel in the design, so sand and other inclusions do not have a harmful effect on the internal surfaces of the unit.
Alpha2 circulation pulser
The basic version of the Alpha unit is considered one of the best in the general segment of circular pumps. Today, the fresh Alpha2 modification is also gaining popularity, the list of advantages of which notes 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 a supply, the Grundfos circulation pump is able to provide a pressure of up to 8 m, which allows serving private households with an area of up to 300 m 2. The installation also implemented protective systems, among which - automatic restart in case of a “dry” run. In general, the developers paid special attention to the starting characteristics. So, even after a long standby time, the unit starts up at the beginning of the heating season.
Well pump MP 1
The Danish company also has a wide range of well pumps, which are also intended for sampling groundwater. These include the MP 1 model, which allows you to perform well cleaning procedures, as well as pumping out contaminated media. Compact pumps for the Grundfos well of this series are suitable for work at a depth of up to 80 m. At the same time, the diameter of the created well can be only 2 inches. The unit is characterized by balanced technical and operational performance. For example, the installation capacity is 2.5 m 3 / h at a voltage of 220 V.
DPK and DWK submersible pumps
The basis of the submersible-type aggregate family is formed by two series - DPK and DWK. Both modifications are designed to perform drainage and drainage operations. The DWK version has an upper discharge pipe, 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 pipe, so that it can be installed on an annular base or using an automatic pipe coupling. Therefore, the submersible pump "Grundfos" in the performance of DPK is advisable to use in continuous operation, requiring a stationary installation. In both cases, the units provide a capacity of about 430 m 3 / h, delivering a pressure of 102 m. Based on the results of operation, users characterize the models as wear-resistant, efficient in pumping and flexible in installation operations.
JP self-priming unit
If you need a universal apparatus for household work in a private house or on a garden plot, then the JP model is suitable. This is a small-sized Grundfos pump, the characteristics of which are optimal for individual use - the capacity reaches 4.5 m 3 / h and the head about 50 m. There are two modifications of the unit. The basic version is a block design with a lid, a lantern and a base plate made of composite materials. The second option provides the same device, but the main working parts are made of stainless steel.
To implement water supply functions with low requirements for pressure head, the manufacturer recommends supplementing the installation with the Grundfos pressure regulator. Pumps in this configuration can provide a stable rise of water from an 8-meter depth at a pressure of 6 Bar.
Well pump SPO
Another representative of the household segment, focused specifically on the use of cottages and country houses. The SPO design is predominantly made of corrosion-resistant components, and high-quality stainless steel was used in the manufacture of the flow part and the chamber of the guide apparatus. The model provides a flow of up 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. Downhole water intake, for example, is possible at points with a diameter of 5-6 inches. But mainly such models are used to collect water from precipitation, maintain pressure in water supply systems and as submersible installations for irrigation of gardens and vegetable gardens. The features of the unit include a double shaft seal at the ends, the possibility of using a float switch and, in general, wide installation possibilities.
Hydro MPC Pump Station
In addition to appliances for domestic use, the manufacturer produces reliable equipment for commercial and industrial facilities. High-tech representatives of this group include the Hydro MPC high-pressure station. The installation provides water supply in volumes of the order of 1080 m 3 / h, and the pressure in this case reaches 155 m. The maximum pressure level in the basic version is 16 Bar, and in special modifications it is increased to 25 Bar.
Separately, it is worth noting the control system, which is implemented using the special Grundfos technology. The pumps in the MPC series can operate automatically and in accordance with the settings made through the control panel with the controller. The intelligent system allows you to quickly adapt the station to the needs of the user, which ultimately ensures operation in optimum performance mode with minimal energy consumption.
