Multi Spring Reversed Balanced Seals, externally mounted and equipped with multiple coil springs, use process fluid pressure to maintain a tight seal between faces, making them highly efficient for both vacuum and high-pressure environments.

As Pusher Type Reversed Balanced Seals, they offer a key advantage—their design does not require stepped shafts or sleeves for pressure balancing. This makes them particularly well-suited for applications involving mildly corrosive or contaminated media, as the metallic parts are effectively kept out of contact with the process fluid.

Another major benefit of these seals is their ability to limit elastomer movement, which helps reduce shaft wear and minimizes the risk of fretting. This makes them a dependable sealing option for applications where protecting the shaft surface is a priority.
