Multi spring & wave spring seals

Multi Spring Unbalanced Seal

• Shaft10 to 100 mm
• Pressure20 bar (max)
• Temperature−40 to 250 °C

The Multi-Spring Unbalanced Mechanical Seal is a highly versatile, compact pusher-type seal designed for low-to-medium pressure applications. Unlike single-coil variants, this design features an array of multiple small springs distributed evenly around the shaft. This configuration provides a perfectly uniform, 360-degree axial load on the seal faces, ensuring exceptional sealing performance even in high-speed applications or setups prone to minor shaft misalignment. Because it is unbalanced, it mounts directly onto standard straight shafts without the need for expensive shaft stepping or specialized sleeves, making it an economical yet high-performance choice for clean fluid systems.
