Application Success


Make: Meyer
Model: 26X26HDX
Industry: Power Generation


A rotary feeder application in the scrubber area between the ash silo and ash slurry tank constantly leaked ash. This created an environmental and safety concern due to ash coating the environment.

Packing had to be replaced weekly, significantly increasing maintenance costs and downtime. The plant was frustrated and desperate for a solution that worked.


An Inpro/Seal® Air Mizer® shaft seal was installed in July 2018. The Air Mizer seal is a non-contacting, non-wearing shaft seal that uses a positive air purge to permanently eliminate leakage.


The plant stated that success would be measured by a seal that could go one month without leaking. The Inpro/Seal Air Mizer shaft seal has run maintenance free, with zero leakage, since installation.
