...The WaterPump Cannot 'Take-In' MORE Liquid, Than It can Pump Out Through the Thermostat.
Hence, the Restriction to Flow, Regardless of the Pressure (At the Thermostat), The Coolant would just 'Back-Up' on the SUCTION side of the Pump, and the Pressure would be Lowered. The LOWERING of Pressure is what Causes Cavitation. Cavitation....The Release of Gas 'Bubbles', gas that was previously 'Held' within the Liquid because it was under pressure. I have seen The Erosion of Hardened Steel caused by Cavitation. Erosion similar to a Water Jet Cutter. Yes! Unbelievable!! And in That regard, JFB is absolutely Correct!

Your Correct about the 'Head', though.

One more thing, Pumps Do Not 'SUCK'. They just provide a 'Void' and create Flow. And Pumps do Not Create Pressure. Pressure is created when there is a Restriction to Flow, the creation of a 'Head'.
