Noisy Pondmaster Mark II

So I've finally set the sump up on the big tank but my Pondmaster 4900 is making one hell of a noise. It's like a washing machine with an off balance load trying to spin at full speed. The resonance is just right that is makes the whole house feel like it's shaking even though the sump is on a concrete floor.

I'm assuming it's the impeller? so will look into that. any other ideas of what it could be? are these pumps just noisy anyway?
