Axial water pump impeller 700 mm, 4 blades
Model designed and computed with the Heliciel software. Design point: 6610.8 m³/h at 8.0 m (78663 Pa) and 730 rpm, in water. Four-blade axial impeller for a 700 mm tube: high flow at low head (lifting, circulation, aquaculture).
The pack contains the complete propeller as a full-definition STL with root fillet, STEP surfaces (complete propeller and one blade), the Heliciel .hlc project and the computation records.

Need a propeller for your own parameters?
This model was designed and computed with the Heliciel software. For a custom propeller there are two ways: the Heliciel software (Windows: computation, 3D view, STL and STEP exports), and the Heliciel MCP connector, which lets your AI assistant — ChatGPT, Claude, Le Chat and any MCP client — compute a real propeller, with a free 1-day discovery pass.
