Back to the future!

After six hours, and a trip to West Marine to buy yet another handful of plumbing fittings, we now have a working seawater circulation pump on Eolian, and our heat pump is once again pumping heat.  The original pump was a Cal Pump, and the new one is a Teel pump, manufactured by Dayton, a major, MAJOR pump manufacturer (model # 1P808A, recorded here so that I have it written down somewhere).

I disassembled the Cal pump, and found that the "impeller" was just 4 straight sheetmetal vanes.  I don't know the failure mode because I haven't completely disassembled it, but I assume it to be saltwater moving along the drive shaft past the shaft seal and back into the motor section causing corrosion.

And I have put away the space heaters.

Back to the future!
