I don't know about this specific pump. Looks like it ought to work fine... being remote I can imagine being a pain to install and route hoses.

One thing to think about though, I've heard high flow pumps can actually be less effective at cooling as the coolant is moving too fast to absorb enough heat. Now I don't know if 50GPM is too much but I think you will do fine with 15-20GPM.
