I used the Danner Pondmaster 6000 for a while,m and it provided the flow I wanted, however the stainless impeller warped and destroyed the pump.

Old thread and you've probably found a solution by now... but I thought I'd point out that you don't have to drill a tank to use an external pump. Run the intake plumbing up and over the side of the sump, include a small line with a ball valve that will allow you to suck the air out of that plumbing and place another full size ball valve on the output of the pump to close while sucking.
