New return pump running very HOT

[Jack]

I'm not sure if such a large pump can be throttled back by %50? I would contact the manufacturer.

YEah, I have an email in to them, but I am not expecting a reply until monday. I thought maybe there might be some good advice here. I thought you could dial them back as much as you wanted. I can try opening it up some more and see if that helps. thanks

Are you dialing back the input or the output? You should only dial back the output.

Have the pump run full out and see what happens.

Barracuda as well at about 50%. Warm but definitely not hot.
