How you mount and plumb the pump can make the noise better or worse. Use soft mounting (even suspending, as I did) on a rigid, not-drum-like surface for the former, and flexible tubing on the inlet and outlet for the latter.
I replaced a ShurFlo 2088 with a Pentair (ShurFlo) 4008 when the old pump refused to prime. It turns out the pump was OK- the problem was with yours truly. I kept the 2088 as a spare.
