Which pump should I get?

Seems like a good idea to have a backup pump, I hear rebuilding these cheap pumps costs nearly as much as replacing them. The General Pump I currently have has last digits "13S", yet Steambrite only lists two models that look identical but have different flow rates. Seems like neither match the specs of my General pump exactly, does it matter as long as its close?

These are the specs for the "13S" model I have. Seems like a slightly lower flow rate and higher psi then the "12S" model listed on Steambrite...

Maybe a better question is, does it matter at all? How does my system max out at 1000 psi or so when the pump can produce 2500 psi? Does the pressure regulator define the high pressure limit. I just learned from Dwain that anything higher will implode the heat exchanger in my CDS.
