On the 12 volt output it says for battery charging. But what would happen if I hooked it up to an on demand pump. Would this cause any damage to the pump or generator?

That voltage might vary between 11 and 16 volts.
If your application tolerates that and current demand
is below the spec of the generator, go ahead.

Thanks. If application doesn't tolerate it the damage would only be to the pump though right? Is there any risk of damaging the generator itself?

FWIW, this is what I want to power http://www.amazon.com/gp/product/B00...ef=oss_product

The voltage has to be over 12 volts to charge, and normally 13.8.
Most any 12 volt device must opperate betweeen 12-16 volts.
All 12 volt electronics must tolerate 16 volts. The generator
will try to adjust the 12 volt output as load demands.
A motor should not be a problem ,except starting
amps can be 3-6 times opperating amps. Thas why you need
extra KW for those refridgerator loads.
Some generators use a 12 volt fuse on the 12 volt output which can blow.

If you've got the generator running and need to pump a lot of water,
I'd use a 110 volt AC pump instead, something like a shallow well
pump.

A friend, with a Ferro-cement boat, bought a sump-pump, I believe they
are called. 220 VAC and look much like a normal 12 VDC bilge pump, but
much larger.

A year or so later he ran head on into a rock (a long story having to
with "cross track error" here) and knocked a hole in the boat. Said
later that the only thing that kept him afloat until he could locate
the damage and stuff some cushions in the hole was the Sump Pump.

If the max output current is less than that of the pump it should be OK.
Probably not good if they are the same :-)
