Until something better (stronger) comes along, I use Poseidon pumps for return pumps even if I have to use two of them. They are available as pressure or volume pumps, dead quiet, and no significant heat transfer. They run at about 130F externally. |
Absolutely, the eheims are good pumps but unfortunately don't meet everyone's flow requirements like you said. I don't have experience with the other pumps you mentioned but maybe it's hard to find a real comparison because it doesn't exist. Making a high flow magnetically driven pump that runs quiet and cool just might be difficult which would explain why prices are high.
