AM CEMA

Complete shaft sealing system for CEMA screw conveyors

Shaft movement on screw conveyors causes premature seal failure. Common sealing methods rely on dynamic contact with the shaft to create a seal. Radial and angular shaft movement cause the seal to wear rapidly, creating a leak path. This leads to higher production costs, increased maintenance, environmental concerns and even unsafe working conditions.

Inpro/Seal® AM (Air Mizer®) Solutions shaft seals provide a permanent sealing solution for screw conveyors.

Designed specifically for CEMA screw conveyors, the AM CEMA design creates an effective seal by utilizing a positive air, or inert gas, purge between the rotor and stator clearance, preventing leakage.

The permanent, non-wearing AM CEMA shaft seal requires virtually no maintenance or need for expensive rebuild kits. Unlike conventional contact seals, the AM CEMA shaft seal can fully articulate to accommodate radial run-out and angular misalignment simultaneously.
