flaws that make them somehow unusable for normal applications.

They may have an involute splined shaft that you can't find a pulley
or coupler for, and have to make it like I did.

The replacement keyed shaft hydraulic pump I bought from Bailey's for
$80 has been OK so far.

The 11 GPM log splitter pumps take a 5 HP gas engine.

You could monitor the 12V pump with an infrared thermometer and an
ammeter while you made tests. I modified a battery charger into an
adjustable 12V supply and used it to check out the HF 12V bilge pump
yesterday. I bought the pump to water my lawn from the rain barrels.
It doesn't seem to mind a high back pressure and flow restriction.
