  • ALPHA2 - High-Efficiency Circulator Pump
    Grundfos ALPHA2 is versatile and efficient whether you use one of its seven speed or pressure control settings or simply leave it on the ground breaking factory AUTOADAPT™ mode. The ALPHA2's ECM motor technology can replace over 30 competitor pump models....

  • The ALPHA2 with its ECM motor design reduces energy consumption by 50%, and in AUTOADAPT mode, 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% ensuring
    the lowest possible energy consumption without sacrificing comfort.

    ALPHA2 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
    • The large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute
    • For installation, you have the flexibility to use either our unique ALPHA Plug with line cord or the ALPHA2 with terminal box for conduit connections
    • ALPHA2 is complete with an integrated check-valve, foam insulation jacket for CI only, and nut captures for flanges. ALPHA2 comes in both cast iron and stainless steel models
    • Robust startup enables the ALPHA2 to continuously attempt to restart – indefinitely – in blocked rotor conditions
    • ALPHA2 can be used as a replacement for more than 30 competitor pump models

    ALPHA2 Applications: Heating and cooling, Hot water recirculation

  • ALPHA2 26-99 - Medium-Sized Efficient Circulator
