Valuable benefits of the diamond coating
Mechanical seals are a factor that has a decisive effect on the cost-effectiveness of your operation. Because their wear determines the productivity of the entire system, whether it is a pump, agitator or compressor. What causes damage to the seal faces? One reason is dry running which is often unavoidable due to insufficient lubrication or when gas-lubricated seal faces get in contact. The resulting temperature rise causes the seal to wear. And ultimately results in system downtimes.
EagleBurgmann has solved this problem which directly affects the success of your plant. The solution is DiamondFace. Thanks to DiamondFace, the service life of mechanical seals is increased several times over, the maintenance intervals are extended accordingly and the life cycle costs are greatly reduced. The advantages for the operator are clear:
Best operational performance
- Increased service life for the mechanical seal and thus the entire system
Minimum maintenance
- Extending the maintenance intervals optimizes the entire system from the costs viewpoint
Minimum Total Life Cycle costs
- These factors all combine to greatly improve life cycle costs.
DiamondFace - An overview
Minimal friction
Minimized friction coefficient when dry running and when exposed to fluid friction. The measured value is 5 times lower than with a standard SiC/SiC pairing.
- No problems caused by inadequate lubrication
- Tolerant to dry running
- Low heat generation
- Less cooling capacity required
- Higher operating temperatures possible
Minimal wear
The average wear of the hard diamond layer in pure dry running mode is an outstanding 0.08 ... 0.2 μm/h.
- Unparalleled wear resistance even with solids or abrasive media
- Long operating period
- Highest chemical resistance
- Highest corrosion resistance
- No abraded particles to contaminate the product
- Excellent heat conductivity
Excellent adhesion
The diamond bonds chemically with the silicon carbide and the resulting layer adhesion exceeds all known practical requirements.
- Extremely robust and solves the problem of crack defects and flaking
- No delamination
- Long operating period
Optimal surface flatness
The surface flatness of DiamondFace seal faces lies within the tolerance range of uncoated silicon carbide seal faces.
- Full functional reliability
