I don't recognize that pump. What's the label on it say? Any model names/numbers? I think the pump might be a bit too big for a reef sump...that sounds like it is over 4000 gph which would be 13x turnover or more. Too much flow through the sump washes a bunch of microbubbles from the skimmer up into your tank which makes the water look cloudy and irritates the corals. It is also a waste of electricity, and probably adds more heat to the tank than you need to. Anything more than 6x turnover through the sump is a waste as that is all the skimmer can process anyway.
Personally, I would replace it with two 1000 gph (at 5' head) pumps. this way if one ever breaks down you still have the other pumping. Redundancy is really important when you start getting into bigger and/or more expensive systems.
You didn't post how much clearance you have under there...?
