Eheim 1250: 1200 l/h @ 0m, 2.0m max head, 28W @ 120VAC, inline

"the pump packs a fast rotating heavy impeller, so vibration control was needed. at first i had a very noticeable humm ringing through the case. i made flexible rubber mounts, that fixed that. even after that i still had some vibration traveling down the tubes that resonated with a panel every now & then (making a buzzing noise). i added strips of Dynamat throughout the case to cancel out the negative energy, if you know what i mean. in the end the 1250 noise is not noticeable over my few quiet fans & drives"
