Description

ALPHA1 is a high-efficiency circulator pump designed for heating and air conditioning systems. The ideal choice for essential functionality. Why choose the Grundfos ALPHA1? The new Grundfos ALPHA1 is for maximum reliability. The ALPHA1 is a robust and high-efficiency canned rotor circulator pump from Grundfos. ALPHA1 is fitted with an electronically commutated motor and designed for circulating liquids in heating and air conditioning systems. ALPHA1 is equipped with intelligent controls and offers three control modes: constant pressure, proportional pressure and constant curve. Each mode has three adjustable speed settings. The new ALPHA1 comes with the well-known features from the ALPHA range you already know: dry-run protection, robust startup and pump venting. Fault finding is fast and easy, using the error symbols on the pump’s operating panel.
