CIRCULATOR GRUNDFOS ALPHA2 GO 25-90 180 220-240V 9

Product code

ALPHA2 GO is an energy-efficient circulator pump designed for heating and cooling systems. It features intelligent control and multiple operating modes: constant pressure, proportional pressure, constant speed, and constant flow. Each mode has adjustable settings. Additionally, the AUTOADAPT function automatically adjusts the pump settings without manual intervention. Replace UPM4 XL, UPM2, and UPM GEO circulator pumps as spare parts in geothermal system units. Check compatibility using the Grundfos GO app. The Grundfos GO app makes commissioning and replacement fast and effortless. The app allows you to check compatibility with old pumps and copy previous setting curves. PWM control enables the ALPHA2 GO pump to function as a replacement pump in geothermal systems. Installation is quick thanks to a pre-installed connector, and various adapters are available as optional accessories. The pump automatically removes air and protects itself against dry running, ensuring quiet and reliable operation. An efficient start-up function reduces the risk of jamming due to sludge, magnetite, and limescale. If the pump jams, the motor repeatedly attempts to start at maximum torque. Ceramic shaft and bearings extend service life and reduce noise. Additionally, the Grundfos GO app's air detection function enables the pump to identify air in the system and automatically remove it through the nearest air vent. The Grundfos GO app also makes it easy to diagnose potential faults using event logs and historical data (e.g., flow, head, temperature estimates, and running times).
