FEATURES

Grundfos Alpha2 15-55F Circulator Pump

ALPHA2 is the best pump to withstand the tough conditions in a heating system, and with four newly added features, it just got even tougher.  First it has a robust start-up, which shakes free any impurities before the pump starts at the beginning of the heating season.  Next is summer mode, and this is an adjustment of the pump’s performance in the summer to the warmer temperature outside – giving customers extra energy efficiency.  It also includes a magnetite resistance, which ensures that no small pieces of metal get stuck in the pump’s vital parts when they are magnetise.  Lastly is dry-running protection, which makes sure the pump never runs without liquid in the system.  This pumps new features are added to the already unrivalled energy efficiency, easy installation and the fact that ALPHA2 covers both your heating demands and up to 90 % of your air-conditioning and cooling demands.

Features:

  • Simple push button
  • Control enables the ALPHA2 to be programmed in one of 3-constant speed, 3-constant pressure, or AUTOADAPT control modes
  • AUTOADAPT selects best performance curve for efficiency and comfort
  • Flow meter for trouble-shooting and balancing
  • Large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute
  • ALPHA2 is complete with an integrated check-valve, foam insulation jacket, and nut captures for flanges
  • Robust startup enables the ALPHA2 to continuously attempt to restart – indefinitely – in blocked rotor conditions
  • Innovative plug simplifies pump connection
  • Insulation shells included
