8X Longer Packing Life in Slurry for Fertilizer Manufacturing



Existing packing lasted only three days due to abrasive gypsum slurry in the fertilizer mineral manufacturing process. Shaft required replacement every few days.

Root Cause

Existing packing failed due to a loss of compression, allowing the gypsum mineral to enter the stuffing box, fret the shaft, damage the packing, and cause uncontrollable leakage.


Achieve 15 days of continuous service to support plant cycle.
