The AM CEMA shaft seal is a complete shaft sealing system for CEMA Screw Conveyors.

The Inpro/Seal AM CEMA is an Air Mizer shaft seal design specifically for CEMA (Conveyor Equipment Manufacturing Association) Screw Conveyors to eliminate product loss and contamination. Designed to last the lifetime of your equipment, the unique design of the AM CEMA shaft seal is maintenance free with no wearing parts. The rotor fully articulates to accommodate radial run-out and angular misalignment simultaneously.

Features and Benefits

  • Standard Dimensions – fits all CEMA Screw Conveyor standard dimensions
  • Internal Chamber – pressurizes sealing medium and directs it to the throttle
  • Stator – pressurizes and efficiently distributes the sealing medium evenly around the circumference of the rotor, creating a positive purge
  • Rotor – rotates with the shaft and fully articulates to accommodate radial run-out and angular misalignment simultaneously
