damn nice catch, basically you have pwm signal which controls pump. if pump is not getting signal pwm it goes into ok lets go max speed so what heated part aka engine would not over heat. self primed no it doesnt know what it has no water, it simply has time delay it should start imediatly ussually, self primed means either it has bearing which alsready has lube, or it may be like in pc world magnetic levitation bearing, fluid bearing, or it using liquid to lubricate there is many options. but they are all physical, not invloved with electronics, also it may have temp sensor, rpm sensor inside. pwm controls it how much fast it must spin, if it heats too much it says go go go, by temp sensr outside lets say
I think the pump does know when it's not pumping water, it will stop and keep doing a check over and over again. Will not overheat itself. It's been a min but i think it turns off after awhile of no water flow. There is a computer on this motor since it is a brushless, it needs to have a simple computer to calculate load and timing of the 3 phase motor.
Awesome Video ~ Just bought a Mishimoto 26x8x2 (ish) Heat Exchanger to custom bumper (under a ranchhand tube) to run to same Intercooler on HJ61 Land Cruiser 12HT Turbo Diesel upgrade ~ Great Idea ~ Look for an OEM pump that 24V ~ maybe EBTPapst 24v DC brushless fans Love to see your finished product
