It sounds like cavitation to me. You can run it silently, but once it
has some head pressure it gets noisy. Perhaps the impellar needs to be
replaced, if it is worn down. Or maybe it is amplified vibration from
the skimmer body, but some flexible tubing between the pump and the
skimmer will deaden the noise.
