At first glance it appeared to be a KF flange due to the appearance. I measured it with a caliber to be about 25 millimeters so I went with a kf-25. The centering ring is just a tiny bit to big. I attempted to force it in but only got it half way. I stopped trying to force it as I thought any more could damage the centering ring. Can someone please help me identify this flange, or inform me if the vacuum pump or centering ring is bad as it would be very helpful. Thank you in advanced.

Re: Need help identifying flange on vacuum pump
Do the dimensions match anything in this table:

or any of the sanitary fitting flanges in the following link? https://hollandaptblog.com/2015/06/15/t ... ion-guide/

It's a kf-25. Just modify the center ring to fit.

Okay, I'll try and sand it down. Are you sure this won't negatively effect the seal?

Re: Need help identifying flange on vacuum pump
Dont mess with the flange, just machine down the diameter of the centering ring. Hopefully you can find someone with a lathe. There are some odd ball sizes out there. I just machined out a fitting that was supposed to be kf-25 but a bit small to fit a normal centering ring. I also have a KF40 elbow that is smaller than normal. It has a adapter KF centering ring so you can mate it to normal KF40. Some odd ball stuff out there...
