This is one of those areas where there are varying theories. The theory I hold to is that the Raw Water Pump (RWP), as a positive displacement pump, will suck the heck out of anything in its path. The nature of this pump makes it self-priming which is why it’s used in marine applications. And because they can pull a significant vertical column of fluid they get used in applications where that is needed. Here is a neat video on how these marvels of engineering work link.Definitely a learning curve for me.
And I should add testing this theory to my list of projects: I have a spare RWP and the capability where I work to set it up and test the vertical draw of these pumps.
