I'm pretty sure it can handle the flow, but maybe someone else can chime in. As far as reliability of these pumps, they're awesome. I have had one of the Pan World pumps on one of my tanks for over two years. It has only been taken off and cleaned once and that was over a year ago. The only reason it got cleaned then was because I moved. I like these better than the Iwaki's; quieter, more reliable and they are more affordable.
