- KINETIC FRICTION REDUCTION (KFR) COATING
The ERL mechanical seal has a KFR coating applied to the silicon carbide face. This coating produces a coefficient of kinetic friction between .05 and .1 when dry. This reduces the temperature increase by 100F in the faces and extends the life of the seal up to 20 minutes when faced with dry running conditions.
- INCREASED HARDNESS
The ERL mechanical seal KFR coating also increases the hardness of the silicon carbide face. The result is a face that is wear resistant to cargo such as crude oil that contain abrasive sand like particles. The hardness of the KFR coating is 50 GPa. This is 2X the hardness of silicon carbide at 25 GPa.
