Garlock Sealing Technologies has developed a leak-free rotary shaft sealing system, the HYDRA-JUST. The company says the system can replace mechanical seals in virtually any industrial pumping application.

Unlike mechanical seals and packing, the new product does not use water to lubricate seal surfaces. Rather, the HYDRA-JUST maintains a bearing relationship to the shaft face in the seal chamber while preventing the process media from migrating into the stuffing box. It creates a radial bearing-to-face seal, which can be less expensive and more cost effective than traditional mechanical seals, the company says.

HYDRA-JUST requires no start-up adjustments or special installation equipment, Garlock says. The system can be installed in less than 1 hour, whereas mechanical seals can take 2 Omega; to 3 hours or longer to install, the company added.
