GRUNDFOS GRUNDFOS High-efficiency circulation pump ALPHA1 GO 15-60 130 220-240V 9H DC0 – 93074271

ALPHA1 GO 15-60 130 The ALPHA1 GO is a highly efficient 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 type has three adjustable speed levels. The replacement of older integrated and external circulator pumps, including the adoption of the characteristic curves, is easily done using the Grundfos GO app and the control panel. Thanks to the new connector, the electrical connection can be established quickly and easily without additional tools. Automatic self-venting and dry-running protection ensure quiet and reliable pump operation. The product is characterized by a robust starting mode that avoids the risk of blockages due to contamination, magnetite, or limescale deposits. In the unwanted event of a pump blockage, the motor continuously attempts to start with the highest possible torque, ensuring a start even under difficult conditions. The ceramic shaft and ceramic bearings are subject to only minimal wear. This increases the service life and reduces the likelihood of noise that can occur with wear due to increased bearing play. Troubleshooting is quick and easy with the help of error codes on the pump's control panel.
