Extruder Shaft Seals

Maximize Product Yield and Decrease Maintenance Costs

The Importance of Reliable Shaft Seals

Extruders in industrial process plants are critical assets that can be challenging to effectively seal. Typical shaft seals are unreliable and maintenance intensive due to their inability to accommodate shaft movement, resulting in shortened seal life, increased maintenance and costly product loss.
