UPS2 25-80 180 Circulating Pump

The Grundfos UPS2 25-80 180 circulator pump is designed to provide high efficiency in heating and domestic hot water recirculation applications in commercial buildings and domestic systems. This pump, equipped with a permanent magnet motor (ECM technology), complies with the strict requirements of Regulation (EC) No. 641/2009 (PUE), ensuring low energy consumption and highly efficient operation. ECM technology allows continuous variable speed control, adapting the pump's performance to the actual needs of the system and maximising energy savings.

The UPS2 25-80 180 model is ideal for circulating clean heating water, meeting the requirements of the VDI 2035 standard, which regulates water quality in heating systems, thus protecting equipment from corrosion and scale build-up. This pump stands out for its ability to deliver reliable and durable performance, as well as being compatible with a wide range of heating and recirculation systems.

One of the main advantages of the Grundfos UPS2 25-80 180 is its ability to operate with an energy efficiency index (EEI) below 0.23, resulting in significant savings on operating costs. The pump features three constant pressure curves and three fixed speeds, which can be easily selected with a single button, facilitating configuration according to the specific needs of the system.

Technical specifications:

• Nominal flow rate: 3.84 m³/h.
• Nominal head: 6.86 m.

Key advantages:

• High energy efficiency: The permanent magnet motor (ECM technology) and variable speed control allow the pump's operation to be adjusted to the system's demand, resulting in considerable energy savings. Its energy efficiency index (EEI) below 0.23 is a clear advantage in terms of reducing operating costs.
• Easy installation and compatibility: This pump is available as a head without a casing, compatible with 4, 5, and 6-metre casings from the 100 family, facilitating installation in existing systems without the need for major modifications. Additionally, no external motor protection devices are required, further simplifying the installation process.
• Durability and resistance: Thanks to its electrodeposition coating, the pump casing is protected against corrosion, ensuring reliable operation over time even in adverse conditions. Moreover, the composite impeller contributes to its durability in demanding working environments.
• Simple setting selection: The Grundfos UPS2 25-80 180 pump allows for easy selection between three constant pressure curves or three fixed speeds with a single button, adapting to the specific needs of the heating or recirculation system.

Main applications:

• Heating systems in commercial buildings: Ideal for maintaining efficient circulation of heating water in large installations.
• Domestic hot water recirculation: Ensures a constant and efficient flow of hot water in domestic and commercial systems.
• Domestic and commercial heating systems: Perfect for replacing old pumps, improving energy efficiency and reducing operating costs.
