The Repack-S range of dynamic sealing solutions are field proven in many industry-leading applications where reliability is critical.
One example of the Repack-S innovative approach to dynamic sealing is DANASPTEP® HF.
High frequency, hydraulics cylinder operation is particularly demanding on seals. Traditional wedge-profiled PTFE composite seals are prone to early failure under the effect of repetitive short strokes and often dry-running conditions. To prevent early failure, Repack-S has developed a better alternative – the DANASPTEP® HF seal.
It uses a modified PTFE seal profile by adding a back heel for additional stability, as well as a rectangular elastomer energiser, making it impossible for the PTFE seal to tilt and break free. In addition, the PTFE grade selected by Repack-S is capable of sustaining dry running conditions. The seal fits within standard ISO / DIN grooves.
Repack-S sealing solutions include a range of proven seal designs: HPX®-Mono®, DANAFLEX®, DANAROTO®, DANAWING®, DANAGLIDE®, DANACAP® and DANASTEP®. All these solutions, when specified properly, offer highly effective, long-lasting and utterly reliable sealing performance.
