ALPHA3 25-60 180

The ALPHA3 has built-in Bluetooth radio and is completely controlled by a smart device via Grundfos GO Remote App. It gives step by step assistance to pump configuration, maintenance and commissioning. The ALPHA3 communicates directly with the Grundfos GO Balance App, which enables the installers to perform fast and easy hydronic balancing.

AUTOADAPT function

The AUTOADAPT function which is integrated in the radiator and underfloor mode continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and the changing heat demand during the year. The AUTOADAPT feature will find the setting that provides optimal comfort with minimal energy consumption. In that, it also makes the commissioning fast, safe, and easy.


  • Radiator mode with AUTOADAPT the simple choice for two-string radiator heating systems
  • Underfloor mode with AUTOADAPT the simple choice for underfloor heating systems
  • Combined radiator and underfloor mode for systems with a combination of heating systems
  • In scheduling and summer mode a realtime clock makes it possible to select when the pump should operate and not to save energy
  • Simple user interface - the pump is completely operated from the Grundfos GO Remote App
  • Alarm and warning log with assistance via Grundfos Go Remote
  • No external motor protection required reducing installation time
  • High-torque start improves startup under harsh conditions
  • Dry-run protection during startup and normal operation
  • Maintenance free due to canned-rotor design and use of robust components
  • ALPHA plug makes electrical installation quick and easy
  • Insulating shells are supplied with pumps to minimize heat loss in heating systems

ALPHA 3 has three modes of adjustment that allow you to adjust the pump setting according to the type of heating system and the point of operation of the installation, they are:

  • proportional-pressure control
  • constant-pressure control
  • constant-curve mode

The display shows the actual power consumption in Watts or actual flow in m3/h. LEDs indicate the actual operating status.
