The ALPHA 26-99 F ECM circulator pump is a high-efficiency, variable-speed wet-rotor solution for hydronic HVAC systems in residential and commercial buildings including applications like space heating, domestic hot water, space cooling, and snow melting. Compatible with gas and oil boilers as a primary pump with options for 0-10 V DC voltage or pulse width modulation (PWM) signals and 50/50 water/glycol mixture. The ALPHA 26-99 also supports cold water ground loops in geothermal heat pump applications and operation in condensing environments where liquid temperature falls below ambient temperature. With AUTOADAPT and multiple control (constant curve, constant pressure, proportional pressure and constant flow), it delivers up to 80% energy savings vs. permanent split capacitor (PSC) circulators. Full functionality is enabled via Bluetooth and the Grundfos GO app, offering guided setup for hydronic applications, precise setpoint control and system air venting. A real-time dashboard displays key metrics like GPM, head (ft), power (W), temperature (F), runtime, and starts. The app also supports commissioning reports, advanced diagnostics with trend data and error logs, and configurable flow limits.
