12V circ pump

[mtnmizer]

Can anyone recommend a 12V DC circ pump for a off grid application?
I have a need to thaw a culvert that has a build up of ice and am building
a hot water system, total length of around 75 ft -- 3/4 pipe, no more than a foot
or two of head, and will be used outdoors battery powered with a solar charger.

Thanks, nice looking pump, but yep it's expensive.

I wonder if I could make this work with a gravity
style system and not use a pump? MM

If you dont need much pressure, bilge pumps for boats are cheap. Hamilton Marine is a good source.
