Beacon Gasket & Seals Co.

The Hydra-Just™ Rotary Seal is a revolutionary concept to replace mechanical seals in industrial pumping applications. This new technology provides leak free, no dilution and "outage-to-outage" service in slurry applications. The unique Hydra-Just™ design allows it to survive system upsets just as the seal's chemical and abrasion resistant components allow it to excel in your toughest applications. Additionally the excellent heat dissipation properties enable the seal to be maintained with as little as 2 US Gallons per hour.
