Active Seal Technology from Flygt enhances sealing reliability and minimizes downtime. The viscous shear of the fluid in the laser-cut grooves creates a hydrodynamic pumping effect that directs any liquid on the stator side back to the buffer-fluid side of the seal. By minimizing accumulated leakage into the stator housing and/or inspection chamber, Active Seal reduces the risk for bearing and stator failure. The technology especially benefits products in continuous operation, where the demands on the seals’ ability to prevent leakage are high. Active Seal functionality is available on a selected range of Flygt Plug-in Seals and double seal systems with separate single seals.
