Tobee® Slurry Pump Packing E111Q05 is an important part of stuffing box used to gland seal. It is used to prevent leakage of fluid, such as water or slurry, chemicals, between sliding or turning parts of slurry pumps. The gland nut allows the packing material to be compressed to form a watertight seal and prevent the slurry from leaking up the shaft when the tap is turned on.
