Compare that to a positive displacement (gear/piston etc) pump. Here you will have pressure of a nature that the jet can shoot through you hand, or crack a cylinder or bend a conrod!
The thermostat in the Diesel will have nothing to do with pressure would be my thinking.

I would expect the centrifugal pump of this type to be able produce no more than around 0.5 PSI of pressure. This type of pump relies on wide unrestricted flow passages, to pump relatively large volumes. Minimal pressure, but large volumes.
