Grundfos 26-99 Circulation Pump Noise - What are your thoughts?

In this video, I'm actually asking for your input and expertise. I have a Grundfos 26-99 circulation pump that is making a noise that is pretty annoying at times. I don't think it's cause for alarm, but I do believe it means I'm going to need a new pump, or a pump cartridge at some point. The cartridge that has all the moving parts can be removed from the pump and replaced individually. I believe that cartridge will fit ALL the 26-99 series pumps, but I want to make sure. Also, if you happen to have parts for one of these pumps, or any of the Honeywell V8043F1036 replacement powerheads I also show that you want to get rid of free or really cheap, let me know. I would certainly appreciate any help you guys can offer.
