Grundfos High-Efficiency Circulating Pump ALPHA1 GO 32-80 180 220-240V 9H DC0

ALPHA1 GO 32-80 180 The ALPHA1 GO is a high-efficiency circulator pump with an electronically commutated motor. It is designed for circulating liquids in heating and air conditioning systems. The ALPHA1 GO features intelligent control and offers three control modes: constant pressure, proportional pressure, and constant curve. Each control mode has three adjustable speed levels. The replacement of older integrated and external circulator pumps, including the adoption of characteristic curves, is easily performed using the Grundfos GO app and the control panel. Thanks to the new connector, the electrical connection can be made quickly and easily without additional tools. Automatic self-venting and dry-running protection ensure quiet and reliable pump operation. The product features a robust start-up mode that prevents the risk of blockages caused by impurities, magnetite, or scale deposits. In the event of an unwanted pump blockage, the motor continuously attempts to start with the highest possible torque, ensuring start-up even under difficult conditions. The ceramic shaft and ceramic bearings are subject to minimal wear. This increases longevity and reduces the likelihood of noise, such as that which can occur with wear due to increased bearing play. Troubleshooting is quick and easy with the error codes on the pump's control panel.
