TD-550芳纶纤维盘根，又称耐磨盘根。该盘根由高质量芳纶纤维浸渍四氟乳液和润滑添加剂编织而成。有较好的耐化学性，高回弹，低冷流。具有极好的高转速、高模数的性质（被称为人造金属线）。所以，与其它类型的盘根比较，它能抵抗颗粒结晶介质和更高的温度既可单独使用也可与其它盘根组合。在泵系统上是很好的石棉替代产品。最突出的性能是高强度，同时也有较好的耐化学性，高回弹，低冷流，且易快速拆装。广泛应用于各个工业领域，如化工、炼油、医药、食品、制糖、造纸及电力行业；泵、阀和混合器等经常用于旋转的

TD-550 Aramid packing The packing made ofhigh quality aramid fibers with PTFE-lmpregnation and lunricant additive. Extremely hard wearing. It shows good chemical resistance, high elasticity and very low cold flow. Compare with other kinds of packing, it can resist more severe media and higher perssure.

It is an universal packing, can be used for pumps in all types of industry such as chemical, petrochemical, pharmaceutical, food and sugar industries, pump and paper mills, power stations etc. It is also a durable packing able to withstand granular and abrasive applocatons,

适用于含固体颗粒的易磨损介质，推荐使用于过热蒸汽、溶剂、液化汽、糖浆及其它易磨流体。在未加冷却液的情况下能应用于温度为160度的热水。

建议：泵轴或防护套的表面硬度要达到60HRC

Designed for serve on superheated steam, solvents, liquefied gases, sugar syrup and other abrasive fluids. For hot water applications it can be used uncooled up to 160℃.
