new 6080 noise

[Johney01]

Just setup my new tunze 6080 with magent holders, magnets work great. The 6080 however is emmiting a buzzing noise, not real loud but its definitely noticeable when my other pumps are turned off. And you can make it out when my other pumps are on, is this normal? seems to be running ok

It is normal when they are new, they quiet down substantially in a couple weeks.
