Features & Benefits:

  • Tool-less, single-step access to rotor and internal surfaces; simplifying cleaning, validation, and inspection.
  • RotorRail™ feature maintains rotor and endplate alignment during dis-assembly; ensures fast and accurate rotor and endplate re-alignment during re-assembly.
  • Available in 4 heights, from 10 5/8"H to 18 3/8"H; and 4 flange diameters from 4" to 18".
  • CNC-machined components and housing provide precision tolerances; eliminates axial shaft movement, extends maintenance cycles.
  • Outboard bearing design protects bearings in high-temperature and high-PSIG applications; removes bearings from direct path of damaging contaminants.
  • Easily manages pressure differentials up to 15 PSIG.
  • Excellent performance in high-temperature applications up to 500°F.
  • 8-vane rotor with beveled tips and sides.
  • Direct-drive motor package.
