Screw Conveyor Shaft Sealing

Complete Shaft Sealing System for CEMA Screw Conveyors

The Importance of Reliable Shaft Seals

Shaft movement on screw conveyors causes premature seal failure. Common sealing methods rely on dynamic contact with the shaft to create the seal. Shaft movement causes the seal to wear rapidly, creating a leak path that leads to high production costs, increased maintenance and unsafe working conditions.

A Permanent Sealing Solution

Effectively seal your CEMA screw conveyors with Inpro/Seal Air Mizer® shaft seals. Unlike packing, or other contact sealing methods, proven Air Mizer shaft seals are a non-contacting permanent sealing solution, requiring zero maintenance or rebuilds. This unique technology handles extreme conditions and can fully articulate to accommodate radial run-out and angular misalignment simultaneously.
