For what its worth, If you want reliability and good insurance, you will not use any other pump except and turbowerx.
End of story.
Ive tried many different pumps, gear, diaphram etc. The turbowerx is by far the best pump on the market and will do far more then you want, its rated to run dry if need be, not that it will, but its not something you need to worry about, depending on how mysetup turns out, it might be getting one, depending on where the turbo gets mounted.
Turbowerx FTW.
