the 2000 and 2000/1 are the same pump, the difference is the impeller and the max head height it can get to. the impeller got changed to a single piece impeller (impeller + shaft are 1 piece) while the old one (2000) are 2 seperate pieces. the AB2000 has a 1.6m head height and uses 18W i believe. the AB2000/1 has a 3.0m head height and uses 18W as well, i dont know what they changed for the head height increase.
The deltec PW version draws less watts too i believe around 12W instead of 18W which is a plus!
