Maxx pumps questions

I was curious about these MAXX pumps. I know Torrent and Skat are probably the best out there, alittle out of budget for me , curious about the Maxx 155 , 12 and 14 vain, buddy needs cash has one of each, what would be the main deference in the two? He just received them a week ago so there the newest ones out there.
not sure if this is the right place for this question, feel free to move to this to a different location. any info on these pumps would be greatly appreciated
 
seem to be good pumps and very little to no complaints even on the www.
not much difference between 12 or 14v.the 14v will load the motor a little more but probably not enough to tell a difference. not sure what size hubs they are though.
