Description

The new ALPHA2 takes reliability in small domestic circulators to new heights. Even in systems where the operational environment is a challenge, the ALPHA2 will ensure long-lasting trouble-free operation with no risk of blockage. If you want to leave your customers with a completely trouble-free heating solution, the new ALPHA2 is a premium choice.

ALPHA2 is versatile and efficient whether you use one of its seven speed, pressure control settings, or simply leave it on the factory setting AUTOADAPT™.

The ECM motor design reduces energy consumption by 50%, and in AUTOADAPTmode, will automatically analyze the heating system, find the optimum setting, continue to adjust its operation to changes in demand, and reduce power consumption by up to 85%. This to ensure the lowest possible energy consumption without sacrificing comfort.


The Grundfos ALPHA2 circulator with AUTOADAPT are predicated on:

  • 65-years of hydronic experience of how pumps work in countless applications and operating environments
  • 15+ years of ECM motor experience in the market
  • ALPHA2 materials and design resist blockage from magnetite and iron oxide particles found in closed hydronic systems.


Key Features and Benefits:

  •  Simple push button
  • Control enables the ALPHA2 to be programmed in one of 3-constant speed,
  • 3-constant pressure, or AUTOADAPT control modes. The current operating mode is always visible on the ALPHA2’s LED display
