Hello and welcome.
1. while you show up (you didn't do it in the first post)
2. of centrifugal pumps there are in bizzeffe
3. What program do you want to draw? if it is sw the correct section would be in sw not in this part of the forum
4. You're an engineer, you should start cuffing first and then maybe ask, don't you think?
You could start with the blades but, I repeat, if you can use sw well, otherwise I think you have to study the software first.
