CIRCULATOR GRUNDFOS ALPHA1 20-40 N 150

Grundfos Alpha1 is a reliable and high-efficiency circulator pump with a sealed rotor. Alpha1 is an ideal choice for both new installations and replacing old, inefficient circulator pumps in heating systems. It is suitable for heating in commercial buildings and circulating domestic hot water, as well as for heating in residential and industrial applications. Alpha1 offers nine selectable control modes (three for constant speed, constant pressure, and proportional pressure), providing flexibility for your heating application. A simple user interface and quick selection make commissioning easy. The display shows energy consumption and fault codes to facilitate troubleshooting. Alpha1 reduces energy consumption by up to 80% compared to conventional UPS pumps and can be adapted to both single- and two-pipe radiator and underfloor heating systems. Features
