Mash recirculation

[beerisyummy]

Greetings zymurgists,
I’m a BIABer thinking about mash recirculation. I have a Blichmann whirlpool thingie on my mash/brew pot and I use a Blichmann RipTide pump to move wort through my CFC. (Blichmann, you’re welcome for the advertising.) Any reason I couldn’t use this equipment for mash recirculation? Specifically, I think I’d want the option to throttle down the recirc by closing the whirlpool valve halfway, and I’d want to be sure this would not hurt the pump.
Thoughts?

"whirlpool thingie"?
Do you mean an "autosparge valve"?

Cheers!

As long as you throttle flow on the output side of the pump, it should not cause any problems. Throttling on the input side can lead to cavitation in the pump chamber, which can severely damage the impeller and chamber walls.
