Buderus Mixing Station, replace pump

hey all, never had to change a pump on these, basic 15-42 motor?

Any model number on those? I think a 15-58 or maybe the 15-55 Alpha would fit those volutes? Grundfos would know.

Thanks the guy sent pic saying one is making noise. We are asking for pics all the time since we all carry cameras in our pockets. I’ll ask for a close up!
