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

Causes of Overheating in Cartridge Mechanical Seals

Too much heat can cause multiple problems with cartridge mechanical seals. Some heat problems are not seal design or seal installation related.

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.

The Process of Troubleshooting Mechanical Seals - Part 1

The 9 articles in this series will outline common issues with mechanical seals, how to notice them, and troubleshooting tips. The series addresses: wide wear track, centered/miscentered, even/uneven wear track, scoring, chipping, coking, heat cracking or checking, and blistering.
