Key Features

Easy Replacement of Integrated UPS Circulators

By following the step-by-step instructions provided by the GO Replace feature within the Grundfos GO app, installers can easily replace existing integrated UPS circulators. The app provides correct settings to input into ALPHA1 GO’s user interface, eliminating guesswork and ensuring accurate commissioning.

Self-Venting Pump

The ALPHA1 GO automatically removes air from the pump, saving installers time by eliminating the need for manual venting. This feature ensures optimal performance from startup and reduces callbacks related to air-lock issues.

Dry-Running Protection

The ALPHA1 GO will automatically stop if dry-running is detected, preventing damage and avoiding costly breakdowns. This built-in protection extends pump life and reduces maintenance requirements.

Improved Wiring

The ALPHA1 GO comes with a toolless lever connector which enables wiring to be done outside the pump. This innovative design simplifies electrical connections and speeds up installation time.

Robust Startup

The non-magnetic shaft and bearings reduce the risk of blockages from dirt or magnetite while the bearing system helps prevent limescale build-up. If the pump does get blocked, the motor will continuously restart at the highest possible torque, overcoming resistance and restoring operation.

Display Read-Out

An HMI display provides clear feedback on system performance, showing the circulator’s power consumption. This makes it easier to monitor operation and adjust settings for optimal efficiency.


Benefits

Fast Replacement Quick and straightforward pump exchanges with minimal system downtime, getting heating systems back online rapidly.

Simpler and More Accurate Commissioning App-guided setup eliminates manual calculations and ensures correct configuration every time.

Energy Savings and Enhanced Comfort for Residents Low EEI rating (≤ 0.20) delivers efficient operation that reduces electricity costs while maintaining consistent heating comfort.

Reduced Callbacks Self-venting, dry-run protection, and robust startup features prevent common issues that lead to return visits.

Quicker and Easier Maintenance and Troubleshooting Clear display feedback and app connectivity simplify diagnostics and system monitoring.
