Designed for applications in commercial and residential buildings, this pump is equipped with features that make it ideal for efficient heat and hot water distribution, providing long-term reliability and durability. With its encapsulated rotor motor, the bearings are lubricated by the pumped liquid, minimizing maintenance and ensuring smooth operation.

Encapsulated rotor design:
The design of the Grundfos UPS 25-40 N 180 is of the encapsulated rotor type, meaning the motor and pump form an integrated unit, with no need for additional seals and only two gaskets for sealing. This reduces the chances of leaks and ensures stable, low-maintenance performance. The bearings are automatically lubricated with the pumped liquid, which not only extends the equipment's lifespan but also ensures continuous, uninterrupted operation. This feature makes it an ideal choice for applications requiring consistent and reliable performance.

High efficiency with adjustable speed control:
The UPS 25-40 N 180 circulator pump offers three adjustable speeds, allowing users to select the mode that best suits the specific needs of the system. This not only maximizes energy efficiency but also helps reduce energy consumption when full capacity operation is not needed. With a nominal flow rate of 1.67 m³/h and a nominal head of 2.03 meters, this pump is designed to deliver optimal performance in heating and hot water recirculation applications.

Durable and corrosion-resistant materials:
The Grundfos UPS 25-40 N 180 is constructed with high-quality materials, ensuring its durability even in demanding environments. The pump body is made of stainless steel (EN 1.4308), offering excellent corrosion resistance, which is crucial in applications where circulating water may contain impurities or be exposed to extreme temperatures. The composite impeller (PES+30% GF) is corrosion-resistant, ensuring reliable and long-lasting performance under all operating conditions.

Suitable for a wide range of applications:
The UPS 25-40 N 180 pump is perfect for heating commercial and residential buildings as well as domestic hot water recirculation. Its ability to handle a liquid temperature range from 2°C to 110°C makes it extremely versatile. Additionally, it can operate at pressures up to 10 bar, making it a suitable choice for a wide range of heating and hot water recirculation applications.

Ease of installation and maintenance:
With a port-to-port length of 180 mm and 1 1/2 inch G-type connections, the pump is designed for quick and easy installation. The compact size and lightweight design, with a net weight of 2.67 kg, make it easy to handle during installation, saving time and reducing installation costs. Furthermore, the pump does not require external motor protection, further simplifying its setup.

Advanced protections and safety:
The Grundfos UPS 25-40 N 180 is equipped with advanced protections to ensure safe operation. It is certified with CE, VDE, EAC, and WEEE approvals, ensuring compliance with international safety and quality standards. Additionally, it has an IP44 protection rating, meaning it is protected against the ingress of solid particles and water splashes from any direction. This ensures the pump operates safely in a variety of environments.

Additional technical features:

• Power input at maximum speed: 45 W, ensuring efficient operation with low energy consumption.
• Nominal voltage: 1 x 230 V, compatible with most electrical networks.
• Network frequency: 50 Hz.
• Insulation class F, ensuring greater heat resistance in prolonged operation environments.
• Current consumption: Range from 0.12 A to 0.2 A depending on the selected speed, ensuring moderate energy consumption.

In summary, the Grundfos UPS 25-40 N 180 circulator pump is an ideal solution for those seeking a compact, efficient, and durable pump for heating and hot water recirculation applications.
