Challenge

Existing packing lasted only three days due to abrasive gypsum slurry in a fertiliser mineral manufacturing process. The shaft required replacement every few days. The existing packing failed due to a loss of compression, which allowed the gypsum mineral to enter the stuffing box, fret the shaft, damage the packing, and cause uncontrollable leakage. The goal was to achieve 15 days of continuous service to support plant cycle.
