    I agree with Russau - 3" dredge max (barely) but will run a 2" fine. With 98 feet max head that translates into about 42.5 PSI max output, but you won't get that PSI at 149GPM.

    I run a 3" dredge with a 1.5" outlet and 2" inlet pump. No idea what the output and pressure are because i built it from scratch, but i get lots of suction with it. Click image for larger version.
