Problem
In individual cases, the required service lives for high-pressure cleaners were not being achieved with the shaft sealing rings that were previously being used.
Project
Use of new product solutions in order to reliably achieve the required service life.
Application
High-pressure cleaners for professional applications and the consumer sector.
requirement
Confirmation of the required service life of 1080 hours with no leaks during an endurance test, carried out on the customer's test benches with all series conditions in place.
result
- Start-stop sequences at 25-second intervals with pressurisation and a 5-second pause
- Axial movement over 7 mm, 4000 rpm on the swash plate
- No material fatigue during the required service life window
advantage
100% service life achievement with a simultaneous reduction in costs.
