Featuring three constant-pressure control modes, The Grundfos ALPHA1 is a high-efficiency ECM variable speed circulator designed for a wide variety of heating.

The Grundfos ALPHA1 is a high-efficiency, variable speed circulator fitted with electronically commutated motor. Designed for circulating liquids in heating systems.

It features a constant pressure control mode with three settings. The intuitive one-button operation and LED display makes the selection of the settings easy. The large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute.

ALPHA1 materials and design are resistant to blockage from magnetite found in hydronic systems.

The robust startup enables ALPHA1 to continuously attempt to restart – indefinitely – in blocked rotor conditions.

ALPHA1 is complete with an integrated check-valve, and nut captures for flanges.

For power connection two options are available with either line cord or terminal box for conduit connections.
