Hi everyone, I have been building a HERMS system and I have ran into a bit of a problem. My pumps aren't going to have enough power to push my liquids around on my stand. I have two March 809 115 volt 1/25 hp pumps right now. I thought about reducing the diameter of my tubing which is believe is 3/8 silicone tubing (I will have to double check that) and the length which is about 5 feet but even if I did that I still don't think I will have enough power to push it through my HERMS coil. Does anyone have any ideas or recommendations on a more powerful pump? Thanks.
