I’m looking to buy two external pumps (one for my return & one for a closed loop.) I’ve been trying to decide between the cheaper styles like the Gen-x mak-4 & Blueline 1100 pumps, Or the heavy duty styles like the Iwaki MD 55 or Blueline 55 HD
Thanks All :beer: That's what I thought also :thumbup:
Figuring the plumbing & height, I will have around 8' head on the return & depending if I drill the tank for the closed loop of go over the side? I'll have between 2' & 8' head for the closed loop. This is going to be for a 90gal AGA RR.
I'm figuring on pressure rated pumps rated for 500~600 gph from each @ 10' head just to give me a little room for error. Of coarse I will have a ball valve on each so I can control the flow! Thanks!
Very true Jon, but.... (don't you love them buts) wouldn't you still take inconsideration the length between the pump and entry to the close loop system? Depending on if the cls in under the tank or the back of the tank?
