    Material used for the rotating shaft in Flowserve BB2 centrifugal pumps?

    Thank you very much for your response and your help — I really appreciate it! Yes, you're right, if it's an API 610 pump, the shaft material is generally selected according to Table H.2 (I'm also referring to the 10th edition). However, the challenge I'm facing is that determining the material...

    Looking for Traditional Method to Design Centrifugal Pump Impeller 🔧

    Hello everyone, I’ve been searching for quite some time for the traditional method of designing a centrifugal pump impeller — the one based on manual hydraulic calculations, not the modern CFD/CFX-based approach that starts with a meridional surface. I’m specifically looking for a method...

    Request for documents or assistance on mechanical design of conical shaft section in centrifugal pumps

    Hi Artisi, Thank you for your reply. To clarify what I meant by "conical section," I’ve attached an image of a centrifugal pump where I’ve highlighted the part I'm referring to in yellow. It’s the tapered (conical) section of the rotating shaft located near the impeller, which typically...

    design a centrifugal impeller

    Hello everyone,I’m working on the geometric design of a centrifugal pump impeller and need guidance on drawing its meridional (axial) section. Specifically, I’d like to : Determine the axial extension z_E and the radii of curvature R_DS and R_TS for the front and rear shrouds (see Chap. 7.2.2.1...
