Unfortunately, I don't have the box it came in anymore. But the pump itself it says "ExoTerra PT - 2090". I know it was the smallest one on the shelf. The measurement of the pump is only about 1.5" x 2". We have it running large airline tubing from one corner to the other, 4.5' over, 1.5' high. I'm sure the flow would be stronger with a shorter distance and height to travel.
