Blau KDC return pumps

[iLMaRiO]

any deep reviews for the return pumps by Blau?

are they silent? which measured flow at which height?

i'm thinking in buying the 8KDC replacing my current Hydor D6000, just because it has a 32mm hose included, but i need less than 4000 liters/h . during the summer, with the chiller, i use and hydor D12000 at full speed (plumbing is longer and thinner), any noise difference between the 12kdc at lower lever vs the 8kdc at medium levels?

They only talk about noise, nothing about the pump quality.
I'm looking for a review, with charts, tests and so on.

Maybe you'll have more luck with Google than I did. The only ones I could find date back to 2014...
