pump head?
I have been visiting these forums for a while, but have only posted a couple of times because I'm cutting my teeth here and find it easier to learn with my ears open than with my mouth open. That said, I need to clarify something very basic and important to me at this point.
I have recently had correspondence with someone who has expressed a different understanding of "head" than I have.
It is my understanding that to say a 200GPH pump has a 4' head means that it will push an unspecified (perhaps implied by the ID of its outlet) volume of water 4' vertically before sufficient back pressure has accrued to force the stoppage of flow, and only push 200GPH with a theoretical zero restriction on flow. Am I correct?
To my understanding if the same pump in question could push 200gph @ 4', its maximum head would be somewhat greater than 4'.
Thanks
