Glenn,

That is pretty much what I was figuring on other than the
check valves. Not sure I want a center off switch though.
I would prefer that one or the other be on at all times. I'm
also considering putting an hours-meter on each so that I
can balance the use.

I'll also vote for a manual valve on both in parallel......

We're in a seaway, big waves. The pump goes into failure mode, we switch
on the backup and are back in business. Wouldn't it be good if we could
isolate the failed pump for repairs, remove/replace or tear it down for
that new diaphram while the other pump has the load and the first mate or
autopilot is driving? Sure would be nice to be able to get that failed
pump offline while the boat's still underway for repairs. Can't do that

on
the series pumps without some crazy plumbing bypasses and lots of
valves....
