Centrifugal Pump Design

Complete Hydraulic Design, 3D Modeling & Creation of Manufacturing Drawings

In this project, I carried out the design and engineering of an industrial centrifugal pump. Unlike standard 3D modeling, the design is based on solid academic and industrial methods, as well as strict adherence to hydraulic design principles.

Hydraulic Blade Design

My Design Approach (Gülich Methodology) During the development of the impeller geometry, I specifically applied the Gülich methodology and systematically implemented it as follows

• Hydraulic design according to industry standards.

• Detailed assembly modeling in Solid Edge including Bills of Materials (BOM).

• CFD-based optimization to increase efficiency and prevent cavitation.

• Manufacturing-ready technical drawings (according to ISO/DIN).

Die Pumpe wurde für optimale Fertigung und leistungsstarke Fluidsysteme ausgelegt.

• Discretization: I divided the blade camber line into ten equidistant segments to maintain precise control over the geometric curvature.

• Angle Distribution: I linearly transformed the blade angle step-by-step from the inlet to the outlet across these ten segments. This minimizes flow separation and optimizes efficiency.

• Surface Generation (Hub-to-Shroud): First, I constructed the blade profile on the hub contour. By creating a surface-normal projection, I subsequently generated the intersection curve on the shroud to obtain a flow-optimized blade channel in 3D space.
