I replaced my defective Artis pump with a Shurflo 4008, and am considering the "quieting" tricks addressed in a couple of these threads, and at the same time adding an accumulator tank, despite the claim on the pump box that one is not needed with the Shurflo 4008.
One thing I've noticed in all the photos I've reviewed here is that no one seems to be using a strainer on the input side of the pump, although the Shurflo instructions specify one. Until replacing the pump, it hadn't even occurred to me that this might be a good idea.
