Replacement made simple

Grundfos states the ALPHA2 GO 25-75 130 suits most UPM3 and UPM4 pumps and the majority of stand-alone circulators. Use the GO app to verify compatibility and match pump curves.

Check compatibility first

When replacing an integrated UPM3 or UPM4, an FCI signal adapter cable may be needed. Confirm the port-to-port length (130 mm) and connection thread against the old pump before ordering.

Safety

Isolate the electrical supply before working on the pump and allow the system to cool. Electrical connection must be carried out by a competent person in line with BS 7671.

Key features

Four control modes

Constant pressure, proportional pressure, constant flow and constant curve with adjustable setpoints cover radiator, underfloor and mixed systems.

AUTOADAPT

AUTOADAPT selects an energy-efficient setting automatically for radiator and underfloor heating systems.

Guided setup in the GO app

Bluetooth connection to the Grundfos GO app gives guided setup, compatibility checks and trend data for long-term optimisation.

Digital display

A bright digital display shows real-time flow rate, head and power consumption for commissioning and fault finding.

Toolless installer plug

The included toolless installer plug speeds up the electrical connection on site.

Robust and quiet

Self-venting, dry-running protection and a robust start-up help it resist blockage from dirt, limescale and magnetite.
