For $50, it's got to be worth a try. They spec "10Kg spitting out" which is not a legitimate pressure spec, and is meaningless to me. They also spec "50ml/min" which seems like satisfactory volume to me, if there is enough pressure to get to the sight glass on top of the column as well as service all the ways. I expect there is a drain plug in the rear of the grinder base casting (like my 612 has) and it could be plumbed into the pumps reservoir. The original pump location would become an initial settling pool, which is good.
