Installation & Usage Tips

• Always depressurize and flush the system before installation or maintenance.
• Use proper alignment jigs or guides to ensure repeatable insertion depth for consistent seal compression and avoid side-loading the shaft.
• Inspect or replace associated packings and seals when installing the shaft to maintain leak-free operation.
• For applications involving particulate or abrasive materials, add a fine (e.g. 5-micron) upstream filter to reduce wear and extend component life.
• Use appropriate lubrication compatible with your fluid system to minimize friction and prolong seal and shaft interface life.
