Single seal/ unbalanced. Independent of direction of rotation/ rubber bellows

HQ1 mechanical seals of the MG series are amongst the most commonly used. The bellows 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 all the face materials are inter-changeable without having to modify any dimensions. Highly recommended for duties with media containing solids eg.in waste water and sewage applications.
