The AM HD shaft seal provides heavy-duty protection for challenging applications.

The Inpro/Seal AM HD shaft seal is the Air Mizer design for heavy-duty product applications, including large diameter shafts, and severe environments in processing industries. Designed to last the lifetime of your equipment, the AM HD shaft seal is maintenance free with no wearing parts. The patented throttle/stator interface fully articulates to accommodate radial run-out, axial movement and angular misalignment simultaneously.

Features and Benefits

  • Internal Chamber – pressurizes sealing medium and directs it to the throttle
  • Screw On Cap- simplifies throttle replacement and installation
  • Opti-Mizer Throttle – pressurizes and efficiently distributes the sealing medium evenly around the circumference of the shaft, creating a positive purge
  • Throttle/Stator Interface – fully articulates to accommodate radial run-out, axial movement and angular misalignment simultaneously
