Product Description

Multi Spring Balanced Seals are specifically developed for high-pressure sealing applications and fall under the category of pusher-type mechanical seals with multiple springs. Their streamlined and compact construction makes them ideal for a range of rotating machinery such as pumps, agitators, and mixers. Torque is reliably transferred through drive lugs integrated into the retainer, which reduces the risk of slippage on the shaft and sleeve.

These seals offer design flexibility and can be configured in single, double, or tandem setups, supported by compatible external seal support systems. The bellow sealing faces are both interchangeable and easily replaceable, contributing to extended service life and increased adaptability in demanding operational conditions.
