  • Page 55: Stuffing Box Leaks

    5.6 Stuffing box leaks When a seal starts out with a slight leak and the leak decreases while running, it indicates leaks across the seal faces. Run the pump continuously in order to eliminate this issue. Continuous leaks When immediate leaks occur and remain constant, even during operation, it usually indicates either sec- ondary seal (shaft packing) damage, or seal faces that are warped or cracked.
