I'm thinking about a Iwaki MD or WMD-30RLT pump.

570 GPH @ 0' & 510 GPH @ 4' with a max head of 17.7' Note: A differant site showed flow as 480 GPH @ 5' for this same pump.

I've also been told that there is a MD-30RZT that would be even better that the above, but havn't found one yet to check out. Anyone know a site that has the RZT types?

Thanks to MadDog for his suggestions, and stearing me to find this.

Edit: I just found some more stats. The MD-20RLT is a 48 watt rate and the MD-30RLT is much more than I'd have guessed, 115 watts. Wouldn't the higher wattage of the 30 off set it's greater flow and pressure, at least to a high degree? Or would running from the pump to the rad take care of any added heat?
