That makes sense, financially. These things aren't cheap!
How did you come to the conclusion that HU were the burrs for you? I'm finding it all a bit of a gamble because I don't have any way of trying out all the different burr types.
I didnt even consider that the pump would have a part number on it. That should make things much easier.
I have no idea if this is the original pump, but I have owned this machine since 2020, so I've had a fairly good amount of use out of it without any issues. These things really are workhorses!
