Benefits
A properly functioning hydraulic seal cartridge is essential for transferring hydraulic energy efficiently within the intensifier. As seals wear, hydraulic oil bypass increases, causing reduced efficiency, slower stroking speeds, excessive heat, and premature wear on expensive pump components.
Replacing worn hydraulic cartridges helps:
- Restore full hydraulic efficiency
- Maintain consistent cutting pressure
- Improve intensifier cycle consistency
- Reduce hydraulic oil leakage
- Protect hydraulic cylinders and pistons
- Lower maintenance costs
- Extend overall pump life
- Increase machine uptime
