DC12 Pumps
The Phobya DC12-220 is a 12V DC pump aimed at straightforward loops: fit it, wire it, run it. No aquabus, no firmware, no controller required.
Sizing a pump is mostly about head pressure rather than flow rate on paper. A single radiator and one block asks very little of a pump. An external radiator, a distribution plate, or a loop with several blocks in series asks a lot more, and that is where an undersized pump shows up as poor temperatures with no obvious cause.
D5 and DDC pumps, which cover the higher head builds, are in pumps.
