The Grundfos Alpha2 GO 25-75 Circulating Pump is a high-efficiency circulator pump fitted with an electronically commutated motor and designed for circulating liquids in heating and air conditioning systems. The Grundfos GO app offers a range of digital features that simplify the setup process for both new and replacement installations.

• By using Grundfos GO, you can easily verify compatibility when replacing integrated and stand-alone circulator pumps, including replicating exact pump curves.
• ALPHA2 GO is designed with intelligent controls modes: • constant pressure • proportional pressure • constant flow • constant curve.
• The AUTOADAPT setting, available for constant and proportional pressure, removes the need to manually select the pump setpoint.
• The PWM input allows for precise control of the speed, better enabling complete system optimisation.
• The automatic self-venting ability and dry-running protection ensure quiet operation and reliability of the pump
• The product features robust startup which reduces the risk of blockages from dirt, magnetite and limescale build-up
• When the system air detection and venting mode detects air in the system, the circulator pump pulsates to more effectively push air to the closest air removal device.
• The ceramic shaft and bearings experience minimal wear, resulting in a longer lifespan and a reduced likelihood of noise in the system
