The off-center lobe the drives the gerotor spins just as fast as the crankshaft, because it usually is the crankshaft. They're low volume, high viscosity, fairly high pressure pumps. The low volume part may be an impediment.
You actually want the water that hits your exhaust heat exchanger to be as hot as possible. Instead of waiting for the water to cool, better to insulate it.
