Thanks to its compact design, easy installation and a wide range of types, the ALPHA1 L is suitable for most systems where the older, energy-saving pump needs to be replaced with new ones. Pump setup is easy and fast. ALPHA1 L allows, in addition to standard control modes, PWM signal power control

This is a technically and functionally improved replacement of ALPHA2 L pumps.

Advantages of the ALPHA1 L pump:

  • Compact design, easy installation and setup
  • Suitable for heating systems and DHW circulation
  • Cataphoretic surface treatment of the cast iron body
  • A bolt is accessible from the front for eventual deblocking of the pump
  • Possibility to control power via PWM signal
  • Energy-optimised, complies with the ErP directive
  • Extended warranty of 5 years

Suitable applications

  • Radiator systems
  • Underfloor heating systems
  • Boiler circuits
