  1. Robust Design

    • Wear resistant SiC sleeve bearings
    • Impeller with back vanes reduce axial thrust and remove strain from mechanical seal and ball bearings​

  2. Optimized for synthetic heat transfer oil

    • Dry-run safety function for mech. seal
    • Optimized cooling of ball bearings, mech. seal and sleeve bearings.
    • Centerline mounting relieves strain from bearings and coupling
