Seal Position: Head Shaft
Industry: Pulp & Paper
Excessive lime dust leakage from the OEM head shaft seals contaminated the adjacent pillow block bearing and surrounding process area. The OEM sealing method was a braided compression packing. Due to the nature of the product, and the inability to provide any type of flush, the compression packing required constant maintenance and would need to be replaced every three months.
An Inpro/Seal® Air Mizer® CEMA shaft seal was installed. The Air Mizer CEMA is a non-contacting, non-wearing shaft seal specifically for CEMA designed conveying equipment. Its unique design utilizes a positive air purge to permanently eliminate product leakage.
The Air Mizer CEMA shaft seals were installed in 2011 and performance has been outstanding with zero maintenance issues. Replacement seals were ordered in 2020.
