We offer a high-quality range of Retainer-Type Single Spring Mechanical Seals, available in various sizes to meet the diverse needs of our valued customers. To ensure the seals’ reliability and durability, our professionals use premium-grade materials during the production process.
The single helical coil spring design is specifically developed for applications involving dirty media and clogging. Torque transmission from the drive collar to the spring holder and seal ring is effectively managed by robust drive lugs. The ‘V’ packing is spring-energized, providing excellent dynamic sealing. Additionally, all parts are interchangeable, allowing the SS130/SS135 series to easily convert from ‘O-ring ‘ to ‘Wedge’ packing by simply replacing the secondary seal, making it ideal for stock rationalization.
