Style 688 is the latest result of Sealtek research and engineering efforts, and the most advanced split seal in the World.
While still keeping all the features and benefits of the acclaimed Style 600SL cartridge-mounted mechanical seal, which has introduced to the market the concept of conical extension of the stuffing box, Style 688 requires no bigger effort than joining the two parts together and tightening the gland bolts. This enables to dramatically cut the installation time from hours to minutes, reduce the machine downtime and lower the risk of installation-related seal malfunctions.
Style 688 can be applied on a wide range of applications and is the ideal seal for pumps which are difficult to dismantle or are located in hard to reach positions.
The Style 688H Semi-Split version includes a one-piece gland which, after the initial installation, allows the use of split replaceable parts, thus removing the need to dismantle the pump for seal maintenance, while granting lower costs and higher reliability.
