In water pumps, the fluid-immersed rotor must be bedded. Expensive graphite bearings are often used here. These are to be replaced by a plastic solution.
The graphite bearings can be replaced by polymeric bearings. By direct injection of surrounding parts, the number of pump components can also be reduced. By using hydrodynamics, extremely low wear and friction can be achieved.
- Cost advantage
- Increased functional integration
- Low wear
- Low friction
