The Grundfos ALPHA 26-99 F is a medium sized, ECM circulator pump. It's designed for reliable circulation of liquids in residential and commercial heating and hot water recirculation systems. The pump is externally controlled via a low-voltage signal from a system controller, such as one integrated into a boiler or a building management system. In the absence of a control signal, the pump automatically operates at maximum speed to ensure continuous performance. Built for durability, the ALPHA 26-99 F materials and design are resistant to blockage caused by magnetite commonly found in hydronic systems. The unit incudes an integrated check valve for added convenience and system protection.
