Industry: Pulp & Paper
Braided packing life was very short, constantly leaking pulp and black liquor, which would contaminate the agitator gearbox below and even created an environmental and safety concern.The mill couldn’t continually stop production to replace packing to eliminate leaks.
An Inpro/Seal® Air Mizer® shaft seal with adapter plate and lantern ring stuffing box bushing was installed in October 2019. The Inpro/Seal Air Mizer seal is a non-contacting, permanent shaft seal that utilizes a positive air purge on the shaft to eliminate product loss and contamination. The seal was installed with an AM Control Panel with alarm for a fast and efficient air supply setup.
The first seal installation was successful, permanently keeping the pulp and black liquor from leaking. The plant was satisfied with the result and installed two more Air Mizer seals on their two other blow tanks in early 2020.
