The Grundfos ALPHA2 26-99 is a medium sized, energy efficiency circulator fitted with a permanent magnet motor (ECM) and frequency converter. Featuring eight different operating modes including constant pressure AutoAdapt and proportional pressure AutoAdapt, the ALPHA2 26-99 is the perfect fit for any heating application. AutoAdapt functionality enables the ALPHA2 26-99 to control operation automatically within a defined performance range. When set in proportional pressure AutoAdapt or constant pressure AutoAdapt, the pump will automatically analyze the heating system, find the optimum system curve and duty point and continue to adjust its operation to changes in demand. A magnetite resistant design, robust ceramic shaft and stainless-steel bearing plate ensure that the ALPHA2 26-99 reliably delivers the optimal system flow at the lowest possible energy consumption.
