的Sicce Syncra水泵的安静est and most efficient on the market, yet that hasn’t stopped their maker from perfecting the design. Feeling like they had some room to improve the larger Syncra 4 and Syncra 5 water pumps, Sicce worked to make them as quiet as possible, aiming to best the Eheim Hobby pump’s 40dB quietude. By adding baffles in the outlet, a thicker, more robust volute housing and some extra thick silicone rubber feet, Sicce managed to reach the low hanging fruit of improvements.
After over 9 months of engineering Sicce scored a new type of external bearing which looks like a darker ceramic and which really helped the Syncra squeak under the 40dB threshold of sound output they were aiming for. Some of the new and improved Sicce Syncra 4 &5 have already begun shipping and they can be distinguished by the features listed above, and by the black backing as opposed to the old dark gray one.
