American High Performance Seals

Effect of Operating Parameters


  • Speed is related to the generated friction between the seal and the dynamic sealing surface and, therefore, affects the performance of the seal.  Low speed will cause increased friction; high speeds will cause a breakdown in the oil film between the seal and the sealing surface, causing the seal to run dry.
  • Pressure causes extrusion of the seal into the extrusion gap, which exists on the no-pressure side of the seal.  The gap can be increased with a corresponding lowering of work pressure.
  • Brittleness of the seal will result if the temperature is too low or if the temperature is too high.
  • Higher temperature affects the viscosity of the sealing media, resulting in greater extrusion and increased friction, leading to a reduced seal life.
