After bit of research its looking a lot like a BLDC motor.
However what makes me wonder is if there are any internal drivers or coil direct connections ( plug is a 3 pin from what I seen in pictures ) however its hard to tell until one is in hand and verified.

Thanks for the input guys
 I did read a few of these earlier units had really poor controllers and no other external input for control. I also noticed that Neptune / APEX do have a "controller" but due to size I don't believe its a speed controller as well

http://www.reefsupplies.ca/online-st...for-pumps.html I believe they will control the DC pumps as well, there are youtube videos of similar DIY modules controlling DC pumps. I would suggest oversizing and running them at less than full power.

Its easier to run in the "green" than it is to constantly ride the "yellow stripe"! That's why everything I design / work on is a complete overkill! Its not hard to put in a bit extra and have 4 channels capable of 250W in the design and set it up as such that you may never need it. And believe it or not 4 drives isnt much when you look at 1 Main Circulation pump, 1 Skimmer pump and 2 closed loop / wavemakers. In regards to power supplies... Sounds like they are pushing them right to the ragged edge. RMS figures are always a lot more different than the PEAK figures. 24V 400W off the shelf industrial supply maybe better suited then the "bricks" the pumps ship with as well as reduce clutter overall when all your pumps are controlled from one unit!
