Benefits

  • Low temperature in the mechanical seal chamber; no cooling water required thanks to air-cooled bearing bracket with heat barrier.
  • Increased operating reliability of versions for heat transfer applications by an optional two mechanical seals preventing leakage.
  • Higher efficiencies than the previous HPK-L model by continued development of the flow passage within the hydraulic system.
