Introduction




HiperLip® is a series of PTFE rotary lip seals designed and produced by Bucker Co., Ltd. Characterized by low-friction and low-power consumption, HiperLip® is capable of meeting high sealing requirements. Thanks to its excellent PTFE compounds and unique lip construction, HiperLip® is suited for applications with high pressure, extreme temperature, corrosive media, and low lubrication level, making it an ideal replacement for conventional seals with such limitations as the stick-slip problem.


Construction


With a precision pressed steel case to support the lip, HiperLip® PTFE rotary lip seals form stable radial contact pressure between the lip and the shaft surface. Along with a static gasket, HiperLip® provides extra seal-tight performance. For special sizes or high corrosion applications, 100% PTFE HiperLip® designs are also available to replace the use of steel cases. HiperLip® groove size complies with DIN 3760 standards, so it can completely replace conventional seals. The standard material of the metal cases is mild steel (SPCD). SUS304 and SUS316 are also available to meet customers’ specific needs and applications.
