Runs particularly quietly and smoothly, thanks to the soft mechanical bypass control!
The SOFT SERIES is the further development of the proven CLASSIC SERIES. Thanks to the unique, flow-optimised 4-chamber diaphragm, a newly developed smooth running motor and integrated bypass control at the heart of the unit, a particularly smooth and quiet water flow is guaranteed. Each pump head has a non-return valve for over 13 bar. The pump remains quiet without rattling both when starting up and closing the tap.
Prefilter and grommets not included in the scope of delivery, please order separately.
