Looking for Traditional Method to Design Centrifugal Pump Impeller 🔧

[sofia-safi]

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 that allows:

• Calculating all the main geometric dimensions of the impeller (inlet/outlet diameters, blade angles, widths, etc.) based on known operating conditions (Q, H, N, etc.)
• Drawing the traditional cross-section step-by-step based on those calculated dimensions
• Designing the blades using the "method of arcs" or any classical graphical construction technique

I’ve contacted several professionals, but unfortunately haven’t received a clear reference yet. This methodology seems to be less known nowadays, so I’m hoping someone here — maybe with experience in older design techniques or academic knowledge — could share:

• A reference (book, article, thesis…)
• Example designs
• Personal experience or guidance

I would be extremely grateful for any help or direction you can offer.
Thank you in advance for your time and support!


Best regards,
