Features a simple manual switch to select between three performance curves, allowing you to balance the system perfectly for energy efficiency and reduced noise.
The compact 130mm design makes it a hassle-free, direct replacement for standard secondary circulation pumps without needing to alter pipework.
Engineered with ceramic bearings and a canned rotor design to deliver the ultra-quiet, vibration-free performance Grundfos is famous for.
The rotor is directly lubricated by the pumped liquid, meaning no external lubrication or complex maintenance is required over the pump's lifetime.
