Modular heating circuit K31 unmixed with Grundfos Alpha2 pump 25-60 DN25

Pump group for efficient direct heating circuits with AutoAdapt control

This unmixed modular heating circuit including Grundfos pump is a well-designed assembly for direct heating circuits, storage tank charging and variable-temperature heating systems. The high-efficiency pump with AutoAdapt function assists with hydraulic balancing and automatically adjusts performance to suit demand, ensuring energy-saving and reliable operation at all times.

The water-carrying components made of brass and the EPDM seals provide a durable installation, while complete EPP insulation minimises heat loss. Large ball valve handles, integrated thermometers and the ventilation duct for pump cooling make daily operation easy. The flow and return can be swapped onsite, giving you more flexibility during installation. Additionally, the non-return valve in the return can be set manually, allowing you to control heat flow precisely.

Ideal for anyone seeking a proven solution with high efficiency and reliable technology.
