Yep, I've got one sitting in a box waiting to be used. It's a great return pump for a small/medium system. I used one for return on my old 110 gallon. They're very quiet for an external pump with this much flow; not as quiet as the velocity pumps, but they run much cooler. They are pretty conservatively rated for flow, but this is not the pressure version. In any kind of plumbing set up with some head pressure and line/elbow friction, you won't get 1100 GPH.
