Multi Spring Reversed Balance Seal

Multi spring & wave spring seals

Multi Spring Reversed Balance Seal

  • Shaft10 to 100 mm
  • Pressure10 bar (max)
  • Temperature−50 to 200 °C

The Multi-Spring Reverse Balanced Mechanical Seal is an advanced, externally mounted sealing solution engineered for highly corrosive, hazardous, or chemically aggressive applications. By utilizing a reverse balanced configuration, the seal is mounted outside the pump stuffing box. This layout exposes the internal components to the atmosphere rather than the aggressive process fluid, preventing chemical attack on the springs. The balanced design ensures stable performance under high-pressure conditions by minimizing face loading and friction.

Generally used in

Corrosive chemicals, hydrocarbons, general and light chemicals.
