This Grundfos UPM3 AUTO 25-70 Circulating Pump connects internal heating pipework by efficiently circulating water throughout your system. Specifically, it provides a highly durable and precise transfer of heating mediums with a maximum delivery head of 7.0 meters. Furthermore, thanks to the built-in intelligence, you significantly speed up installation by allowing the pump to automatically adjust its performance to the actual system demand without requiring external control units.
Therefore, this Grundfos UPM3 Circulating Pump works perfectly for underfloor heating and modern HVAC systems. Additionally, it easily handles demanding applications, integrating smoothly into appliances or cabinets with limited space options and increased ambient temperatures up to 70°C.
The Boiler Circulating Pump features a robust construction engineered with a durable cast iron body and an ultra-compact glandless design. Moreover, the highly efficient motor operates with a variable power input between 5W and 52W, achieving an impressive Energy Efficiency Index (EEI). As a result, this reliable build makes it fully dependable for long-term continuous operation under a maximum operating pressure of 10 bar.
Key Features & Benefits:
-
Intelligent AUTOADAPT Technology: The Boiler Circulating Pump design allows for automatic performance adjustment according to the actual heat demand of the system. Consequently, you achieve optimal comfort and efficiency without needing to manually configure complex settings out of the box.
-
Versatile Control Modes: The system incorporates 3 distinct control modes and 10 performance curves. For example, you can easily switch between proportional pressure, constant pressure, and constant curve operations. Ultimately, this allows you to create highly adaptable plumbing systems tailored to specific flow requirements.
-
Ultra-Compact & High Efficiency: The unit is designed to be the smallest ever for a circulator, making it perfectly suited for tight manifold cabinets. Importantly, it completely maximizes energy savings by maintaining an A-rated Energy Efficiency Index.
-
Quiet & Stable Operation: The inherent design features a low-noise motor to reduce system vibrations. In particular, this internal structure provides an acoustic function, effectively minimizing operational noise in residential buildings where quiet running is essential.
-
Easy Front Access: The front-facing interface allows for fast configuration and monitoring. Besides that, this performance is fully supported by easy access to the connectors and the de-blocking screw from the front, which significantly reduces maintenance hassles.
