Features

    With over 65 years of hydronic experience, Grundfos continues to lead the way with the ALPHA2. The ALPHA2 15-55FR/LC is a variable speed circulator designed to provide consistent flow in a wide variety of applications. It comes complete with an integrated check-valve, foam insulation jacket, and nut captures for flanges. With a flange constructed of cast iron, the ALPHA2 is designed to provide year after year of reliable use.
  • AUTOADAPT™
  • The ALPHA2's AUTOADAPT™ feature will reduce power consumption by up to 85%; finding the optimum setting and then continuing to adjust as needed.
  • Durable Cast Iron Construction
  • The Grundfos ALPHA2 15-55FR/LC is crafted from cast iron, which gives the pump both extended lifespan and protection against corrosion.
  • Additional Protection
  • The ALPHA1 features an integrated check valve to automatically prevent backflow in your system, a foam insulation jacket, and nut captures for flanges.
  • Easy-to-Use Operation
  • The ALPHA2's simple push-button control allows you to program the pump in one of three constant speed, constant pressure, or AUTOADAPT™ modes.
  • Preset Performance Modes
  • Grundfos ALPHA2 pumps come with several preset operation modes, designed to simplify the integration of the pump into your hydronic system.
  • Large, Easy-to-Read Display
  • The integrated bright LED-lit display allows at-a-glance readings of either flow rate or power consumption.
  • Automatic Restart
  • In blocked rotor conditions, the ALPHA2 will continuously attempt to restart, indefinitely.
  • Product Note
    Cast iron cannot be used in domestic hot water or potable water applications.
