FEATURES
Grundfos ALPHA2 26-99 F Circulator Pump
This medium sized, high-efficiency ECM variable speed circulator is designed for a wide variety of heating and cooling applications. Features eight different operating modes including constant pressure AUTOADAPT and proportional pressure AUTOADAPT.
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 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.
