I want to use this pump to draw water (not pressurized) from a tank, through a radiator, then back to the tank. Is that possible with this pump or does it have to be plumbed to a pressurized water source?
Yes, but there must be water between the tank and the pump, because this pump is not self-priming. Even if it has no pressure, it doesn't matter, because it can suck up as long as there is water.
