Sicce Syncra Nano Pump upto 430 L/H

The little thing is super good, barely audible behind a Hamburg mat filter on the smallest setting! The radiators are not quieter, that's an announcement. Thank you very much

This pump only works quietly at the appropriate backpressure or at half power or below. The design of the impeller is the decisive factor here. Although only three very wide compartments provide quite high performance for the size and low energy consumption at the same time, this is in no way conducive to smooth running. With the appropriate backpressure and the resulting throttling, the pump is quieter. However, if it has a clear path, as with an HMF, the volume is well above the acceptable range for living conditions. Badly designed. German manufacturers have been able to do this better for several decades and that has not changed. For noise-sensitive people, I recommend the Juwel brand circulation pump. They are much quieter after the turnaround time, but unfortunately also (slightly) larger. The company Sicce doesn't come into my house anymore.
