After a lot of long searching, i finally found and bought what i feel to be the best circulation pump available. Its the Jabsco Cyclone 50830-0012. This is the replacement for the older centripuppy pump. Anyways this bad boy flows 30GPM at only 7amps! The older centripuppy flowed 20GPM at more amps. The pump is all stainless steel, and is rated for continous run. I got one coming, and think it should perform nicely. I will let everyone know how it goes.
