Advantages mechanical seal shf / shp

  • Deformation-optimized seal for high sliding velocities and medium pressures
  • Economical due to standardized inner components
  • Universal application for OEM or retrofits of boiler feed water pumps with floating ring seals, labyrinths or packings
  • High flexibility due to adaptation of the connection parts to the pump seal chamber
  • Optimum heat dissipation due to integrated pumping device and optimized seat design
    Insensitive to shaft deflections due to stationary design
  • Short built
