Even/Uneven Wear Track
EVEN WEAR TRACK | UNEVEN WEAR TRACK |
SYMPTOMS:
- Even/uneven wear track
CAUSES:
- Even wear on a seal face usually indicates good contact between the mating seal rings
- Uneven wear on a seal face indicates:
- Distortion of the seal ring due to over tightening, clamping, or excessive pressure
- Distortion due to insufficient gland support
- Misaligned seal rings in a split seal
- Improperly stress relieved component
FAILURE MODES:
- Misinstallation
- Quality/design related issue
SOLUTIONS:
- Review installation techniques/instructions
- Check/reduce torque and evenly tighten gland bolts
- Review operating conditions
- Reduce torque and evenly tighten gland bolts

How Can I Extend the Performance Range of Standard Cartridge Mechanical Seals?
In today's global environment, the "one size fits all" approach is used for so many products that we expect it to apply to just about everything. In the mechanical seal industry, one problem with that philosophy is the definition of the word all. Mechanical seals must live in literally every environment under the sun-from extreme hot to extreme cold, wet to dry, solid to gas, acidic to caustic and so on. Until relatively recently, a vast variety of cartridge mechanical seals were needed to accommodate these pump applications.
