The simplest way to run it is full on all the time (or at least when the engine is firing). If you have a controller maybe turn it down for WOT in an attempt to maximize parasitic loss reduction for better output. The problem then is you can overcool as mentioned above.
If you look at how electric and other types of controllable waterpumps are run on vehicles that come with them from the factory (BMWs for example), you'll see flow rate varying with speed and load and also turning off during a cold start. They can work with the thermostat to control water temperature and also the temperature rise across the engine by varying flow rate.
