GRAPHALLOY® Retrofit Delivers 15% More Flow and 80% Less Vibration in Overhung FCC Pumps
An East-Coast refinery was living with chronic vibration and bi-weekly overhauls on its two-stage overhung feed pumps. Swapping the steel wear rings and bushings for GRAPHALLOY® self-lubricating parts turned the story around:

GRAPHALLOY® Bearings From Frequent Failures to Four Years of Reliability in Snack Food Fryers
In their continuous fryer systems, manufactured by Heat & Control®, this producer faced recurring failures with greased ball bearings. Bearings used on belts and paddles in the fryers experienced extreme conditions:
- Exposure to 400°F
- Continuous splashing with hot oil
- Full submersion in cooking oil for certain locations
Despite regular re-greasing, the bearings on the hold-down belt had to be replaced every 3 to 4 months. Maintenance was costly, and unplanned downtime was disruptive.
