Hydra-Just is a leak-free rotary shaft sealing system that does not use water to lubricate seal surfaces. The seal forms and maintains a bearing relationship to the shaft face in the seal chamber while preventing the process media from migrating into the stuffing box. It’s particularly suitable for use in hostile, abrasive environments. The system does not require startup adjustment and installs in less than one hour, the company reports.
