La description

Profile 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 e.g. in waste water and sewage applications Operating limits Specification: *0~**0mm Pressure:≤1.2Mpa Temperature: **0? ~ **0? Linear speed:≤*0 m/s Axial movement:±0.5mm Combination of materials Sealing face: graphite, silicon carbide, tungsten carbide, aluminum oxide Secondary sealing: acrylonitrile rubber, fluorine rubber, ethylene propylene rubber Metal component: stainless steel
