[General] Can a vampire's thirst be fully satified?

The well-known characteristic of vampires is their thirst for blood, that is only temporarily satisfied when feeding on a mortal. So, I had this idea in my head of setting up a device or a magic spell what would feed a vampire an equivalent of his normal blood intake during feeding but at constant rate infinitely. Assuming that the logistics of setting it up and supplying the blood are satisfied,would the vampire still experience any hunger? Would it require larger and larger amounts? Could it become "satisfied", not feeling like drinking any more for at least a while. I realize that vampires in media usually do other stuff that just feeding but I wonder if that's just out of necessity and whether they would take up being fed constantly if the option was on the table. As a bonus, I wonder how it would affect their powers. Whether there is some hard limit to how much blood a vampire can keep ingesting and getting some benefit out of it or if it can actually keep occurring forever.

I would like to see how different lore compares in these aspects: Buffy, Anne Race, World of Darkness, all those are on the table as well as any others.

Most Vampire varieties can be fed to satiation. In some cases (Being Human, for example) this wouldn't actually be a perfect solution, as drinking blood is incredibly intoxicating. While theoretically, you could try to work out an exact regimen, they would regularly be on binge-cycles and feel the urge for more and more, until they are completely incapacitated.

Furthermore, nearly all Vampire varieties (including Buffy and WoD) do not experience any physical pleasure except for drinking. Their main goals are simply ensuring their safety and ensuring their continued supply of blood. With their blood needs met, they may find themselves lost, without any guiding force in life.

On the other hand, many Vamps (most notably WoD vampires) gain power in direct correlation to how much blood they consume. You'd be handing them a gun with infinite bullets.

Anne Rice's Vampires would benefit the most - they need *less* blood to survive as they age.
