Single Unbalanced Elastomer Bellow MG1 Seal

Mechanical seals of the MG1 series from EagleBurgmann are amongst the most commonly used. The bellow is not subjected to any torsional stress and its ingenious design incorporates several functions, as seal face carrier, secondary sealing element and drive collar.  The seal face is driven through the spring and “L” rings.  There are no bonded joints and the face materials are interchangeable without having to modify any dimensions.  Highly recommended for duties with media containing solids e.g. in wastewater and sewage applications.  Independent of direction of rotation.
