UPS2 32-80 180 Circulating Pump

The Grundfos UPS2 32-80 180 circulator pump is a high-efficiency solution designed for heating applications in commercial buildings and the recirculation of domestic hot water. With its permanent magnet motor based on ECM (Electronic Commutated Motor) technology, this pump excels in offering continuous variable speed control, adapting to system needs and ensuring significant energy savings. Furthermore, it complies with the requirements of Regulation (EC) No. 641/2009 (ErP), making it a sustainable and efficient choice for clean heating water circulation systems.

This model is specially designed to comply with VDI 2035 standards, ensuring it is suitable for the circulation of clean water in heating systems, thus protecting heating systems against corrosion and mineral deposit build-up. The Grundfos UPS2 32-80 180 pump is also compatible with applications in sealed installations, such as boilers, which enhances its versatility in commercial use.

One of the most notable features of the pump is its compact design, which allows for the replacement of the pump head without the need to change the entire housing. This makes it compatible with all 4, 5, and 6-metre housings of the 100 family, facilitating installation in existing systems without the need for costly modifications.

Moreover, the Grundfos UPS2 32-80 180 offers easy selection of constant pressure curves or fixed speeds via a single button, allowing the pump's performance to be adjusted according to the specific demands of the system. This level of flexibility is ideal for optimising pump operation and reducing energy consumption.
