GRAPHALLOY Upgrade Improves MTBF of Refinery's Storm Water Pumps

Engineers at a U.S. refinery’s wastewater treatment plant upgraded the bronze bearings on their vertical turbine pumps in wastewater service to GRAPHALLOY® bushings and solved their packing failures.

This refinery was experiencing frequent bearing failures in their single-stage vertical turbine wastewater pumps. The bronze stuffing box bearing often failed which allowed shaft movement and, in turn, put stress on the packing. This caused the packing to quickly wallow out resulting in a leaking packing.
