Centrifugal pump with motor, or generator with many mechanical deails, but without electricbox and wires and sensors.
It was made in BLENDER. Very easy to modify. Everything is NONDESTRUCTIVE and labeled. I want to do it with 100 000 tris. It cost lot of tweaking with modifiers and control verts to have god face orientation and not doubles. I used animation drivers to control geometry of some cutters, many modifiers like mirror, array, screw, boleans, curving, weld,.... Only little procedural textures, and one halfcutter collection with aplied modifiers.
Clear version for render: Verts: 46 249 Faces: 43 243 Tris: 99 475
