Bubble-magus NAC7 C7 skimmer conversion kit for SP2000 pump

thingiverse

Marine aquarium skimmer conversion/renewal kit. Bubble-magus NAC7 which were called later as C7, used the Atman PH2500 pump, replaced with SP2000 pump. The skimmer has two major parts: a housing with bits and bobs to make skimming work and a pump with a needle wheel to make bubbles. The former does not really break over the years the latter get noisy and eventually dies. You cannot buy an old pump as a replacement and why would you do that? Pumps are now much less noisy, use less power, has better features etc. So replacement is a good option. My pump lost most of its needles during the years (got less effective) then the rotor died, replacement could not get found. All connecting elements had to rebuilt to accomodate the modern pump.
