So, the paper gives some geometric parameters but I don't need whether this is enough or not. The pump type is mentioned but when I search it only gives me performance data. The pump type is IS125-100. The below geometric parameters are mentioned. pump1.PNG pump2.PNG My question is whether this information is enough for creating a model, and what is the best Ansys product to draw with? If it's not enough, what is the best practice, can I find the data somewhere?

Because then, you would need really more informations than just the basic dimensions of outlet width, outlet diameter and blade count. Very important for you would be the wrap angle of the blade. This would be hard to get, in my opinion. But, if the image is true, the blade seem to be 2D which makes it easy to create once one blade profile is found or calcualted. In general, you can use the Bladegen tool for creating blade geometries.

I would suggest you look into the book "Centrifugal Pumps" by Gülich. Chapter 7.2.2.2 covers the blade design. You could approximate the wrap angle from the image you got and try to iterate through manual calculations until you maybe reach the design (relative angle distribution from inlet to outlet) you want to have.
