How far down can I choke a Eheim 1262 pump?

I was about to pull my aquarium out of our bedroom because it was so loud. I figured out that I had way too much flow on the returns. I put a ball valve in and got it damn near silent. The only thing is I got it choked down 75%. Is it hard on the pump? I'm thinking about going to Eheim 3000 compact. I got that for my skimmer and it is DEAD SILENT. Like I can't tell it's on silent. I can hear a hum from the 1260.

choking the pump on the outlet side is just like adding head pressure or increasing the pipe height. it will make the pump consume less watts but i dont think it will break down.

It's not going to hurt the pump but I would pick up a new smaller return that will run the flow rate you're looking for. Smaller pumps are quieter too
