IIRC, the ones I've seen were 6-10gpm. I don't recall what the pressure
was. I think most are rated in head, rather than psi, like sump pumps.
Here's an example. This one is 12v. You could tap the pack, carry a
separate 12v battery onboard, or use a big DC:DC converter. As a bonus,
you'd then have power for a 12v inverter.
It's rated 7.9gpm and can handle a 20' head.
I'm sure there are plenty of others, no doubt including cheap Chinese-made
Harbor-Fright-type junk that will cost 1/4 as much and last 1/10 as long.
Annnnnddd, sure enough:
Doesn't say it's reversible, though. Claims 3.3gpm, 23' head, 10psi.
continuous power is about half that of the Jabsco.
