Danger Den has the DDC PLUS pumps in stock. However, their website page isn't fully up to date yet. They had update the pump watts and the pump enlarge picture, but didn't update the remainder of the information yet. I've talked with DD last week. The Laing rep will be sending them info to update the page, along with the power and flow curve charts.
Currently, Swiftech and Corsair only carry the 10W version in NA. This is slightly over the D5 P1 (pot-1) setting.
DD is the only one currently who carries the PLUS pump in NA. The PLUS is rated at 12V@18W, 1.5A, 720LPH. This is close to the D5 P3 setting.
The flow would be higher, if the Lee "ROBOTECH" Garbutt mod is done. It should place the pump into the range between the P4 to P5 setting found on the D5. This is not bad for 3/8" (9.5~10mm) size fittings.
