I was thinking it was a different type. I'm not sure if this might help, it did on my external pump. I used a medium size cable tie and put it around the center of the pump and tightened it. This reduces the vibration. I'm not sure if it will work in this situation but you could give it a go. It could be a cheap fix. It should not be that noisy, as it's internal??
