Here is good site to get you started. There are several brands like Jabsco and Flojet that have Dc powered pumps. Other brands have pumps that can be powered by AC or DC. I personally haven’t seen a DC pump in your higher power range.
If I had to use DC I was always looking in the other direction.

You could always get an inverter, and use a standard pump. I'm sure you would loose some efficiency, but depending on the application you may come out better in the end.
