 Design introduction

屏幕截图 2025-09-26 131303 (1)

The particular characteristic of the seal is the special design of the seal edge profile. Two external seal edges act as primary seal for pressures from both sides and prevent any build-up of hydrodynamic pressure over the seal profile and the risk of the blow-by effect. The central back-up and sealing bulge increases the sealing effect*. Grooves are provided on both sides on the plane surfaces to provide activation of the energizing O-Ring. These ensure direct pressure loading of the seal under all operating conditions.



Advantages

  • High static and dynamic sealing effect

  • High abrasion resistance

  • Simple groove design, one-piece piston possible

  • uitable for grooves to ISO 7425
