ALPHA2 26-99 SU, Variable Speed Circulator Pump, 115 volt

Grundfos ALPHA2 is a medium-sized high-efficiency, variable-speed circulator fitted with an electronically commutated motor designed for circulating liquids in heating, cooling, air conditioning and hot water recirculation (HWR) systems. ALPHA2 features constant pressure and proportional pressure control modes with three curves and an AUTOADAPT setting. The AUTOADAPT setting enables the pump to continuously adjust the pump performance to the current heat demand and find the setting that provides optimal comfort with minimal energy consumption. The one-button operation and LED display make the selection of the settings easy. ALPHA2 materials and design are resistant to blockage from magnetite found in hydronic systems. The pump is complete with an integrated check valve. It is fitted with a terminal box for conduit connections.
