MG1 / 12 / 13 Mechanical Seals

MG1 mechanical seals are amongst the most commonly used seals.  The bellows are 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 all the face materials are interchangeable without having to modify any dimensions.  Highly recommended for duties with media containing solids e.g. in waste water and sewerage applications.  The working length on the different MG1 seals varies.
