The Grundfos ALPHA1 is a medium sized high-efficiency, variable speed circulator fitted with electronically commutated motor. Designed for circulating liquids in heating and hot water recirculation systems.
The pump is externally controlled via a low-voltage 0-10 VDC signal by a system controller integrated in a boiler or a building management system. The pump will run at its maximum speed if no signal is present or it fails (e.g. cable break).
ALPHA1 materials and design are resistant to blockage from magnetite found in hydronic systems.ALPHA1 is complete with an integrated check-valve.
