Mayf;
If you want to scrounge around a bit you may be able to find a pump made by
Weldon for aircraft de- icer fluid. These are old- WW II or Korean War
vintage-- but they are little jewels. The flow/pressure curves are optimized
for fairly low flow (you didn't say how fast you needed to transfer the
water) so they may or may not be appropriate. Others made by Pesco, etc.,
have higher flow so may be better for your application. The disadvantage of
the aircraft pumps is that they operate on 28VDC, not 12V.
It is possible to connect another small 12V battery in series with your main
battery to boost the voltage to 24V; under charge it rises to the rated 28V.
In my car I have designed in a 12V to 28V DC-DC converter to operate a
number of things like this.

Many different Jabscos have been used over the years. The all brass
centrifugal seems most prevalant. They pump about 20 gpm. Some Jabsco
"rubber" impellers don't really like much heat. Drag racers I know use them
and cut a little off each blade. CSI and others now make 12v pumps which
will pump 30 to 40 gpm Check out Jegs and Summit...Good Luck
