Can't speak for the MP60 but the MP40 and MP10 power supplies are not the same size. The MP10 is 2"x 4.5", the MP40 is 2" x 5". I would assume that would mean the functionality is not the same either.
.. you do know you can use any equivalent DC power supply. When I mean equivalent is as long as voltage match and power output(Watts or Amps) is the same or more - you're golden
if you have a few pumps and hate bricks get a 40$ 100-200W mean-well psu and wire all pumps to it. I would not be surprised if meanwell psu would be of better quality (cleaner power) and more efficient (less heat) then original bricks.
Edit: there are Meanwells psu with built in battery backup feature - connect your own battery of the size you want.
