gregbot9000 Posted June 14, 2008 Share Posted June 14, 2008 looking for a good closed loop pump(600-700gph) for my 20h build. need opinions please! mag-7, ive run one before, didn't like it to much, sounded it was gonna break.. eheim 1260, never used before. heard they were awesome..but expensive ocean runner2500, have one one on my skimmer seems alright.. any others im missing? or could i go with a smaller gph? -greg Link to comment
Pship Posted June 14, 2008 Share Posted June 14, 2008 Usually a pump that is built to run externally would work best. Once you take head loss into account that mag 7 will probably be putting less than 500 into your tank and that does go far when it is spread out for 2 holes. I would aim for a 1500gph pump at least. I have a 1200gph after head loss for my closed loop and I wish I would have used something large. BTW this is on a 26 gallon. Good luck with your decision. Link to comment
gregbot9000 Posted June 14, 2008 Author Share Posted June 14, 2008 wow really..what pump are you running? Link to comment
Pship Posted June 14, 2008 Share Posted June 14, 2008 This older Quiet One, made by Grundolfs. It is rated for 1200 at 4' of head @ 3/4". Link to comment
BKtomodachi Posted June 14, 2008 Share Posted June 14, 2008 the oceanrunners are good pumps. I bought the 2500 for my closed loop that I'm currently setting up. Link to comment
filefish949 Posted June 14, 2008 Share Posted June 14, 2008 I just got an OR 2500, I like it because it is very energy efficient and will add less heat into your tank than most any other comparable pump, just be careful with part #17, they break if you over torque them Link to comment
Gwoardnog Posted June 15, 2008 Share Posted June 15, 2008 +1 on Eheim and Ocean Runners. OR's are a bit bigger and just a tiny little bit louder than Eheim's ime. Both are great. A bit more than what you need, but I've heard on this board that the Pan World X-X series are extremely quiet and good. Link to comment
Mr. Fosi Posted June 15, 2008 Share Posted June 15, 2008 Panworld's are nice but they have very close tolerances and as such, require frequent servicing. Link to comment
evilc66 Posted June 15, 2008 Share Posted June 15, 2008 BTW, there are virtually no head losses on a closed loop system. There will be some efficiency losses from 90deg bends, but not as severe as you think. Link to comment
jpluttme Posted July 2, 2008 Share Posted July 2, 2008 Panworld/Blueline pumps are good.

wbeavers Posted July 25, 2008 Share Posted July 25, 2008 I used an Ocean Runner 2500 on my setup, and liked it alot. Link to comment
SPS20 Posted July 26, 2008 Share Posted July 26, 2008 IME, Eheims can't be beat for quietness and reliability, but they are expensive. Just my 2 cents. Link to comment

I may have your pump! Link to comment
bdare Posted July 28, 2008 Share Posted July 28, 2008 I have a PanWorld. They are NOT quiet. For the size you are looking for I don't think you can go wrong with either Ocean Runner or Eheim. I also have an Eheim 1260 and it's silent. Spend the money and get a good pump. If you need to replace a bad pump you'll be spending more than if you just bought the good one up front.

vangvace Posted July 28, 2008 Share Posted July 28, 2008 Here's the calcuator you can use to figure out gph. Just remember that because it's a closed loop you leave the verticle length at 0 because it's a non-factor Head loss calc Link to comment
