Sorry, it's not the Dtek is made by EK WaterBlocks. It's the swiftec 655 / Lang D5 pump but with a different top to allow different inlet and outlet options. The part is called "EK-D5 X-TOP - Acetal G1/4 Rev.2" if you want to have a google for it.
I think the tube is 3/4" but I'm not certain so you'd need to check the info for the Tygon tube.
