Size limit for self-priming?
Size limit for self-priming?
(OP)
I'm considering using a 90,000 gpm pump for pumping out a tailings pond. It has a suction diameter of 1 metre or more.
Is it possible to get pumps like this to be self-priming?

Of course, you still need a big vacuum pump or other means to prime the pump for a black start. See documentation for the New Orleans pumps, the subject of much discussion here in the past year. Since you must have the vacuum pump, or a liquid priming pump, in place anyway, maybe you don't really need the big pump to be self- priming.

As you are talkig about pumping tailings, are they abrasive, are there any solids etc.
What configuration is the inlet and discharge pipes.
Any suction lift involved - etc.
Give some more detail on the application so we can advise you further.
