Double acting piston seal

Double acting piston seal for ISO installation spaces

Description

FiPur® double-acting piston seal consisting from a special TPU-based seal ring and an O-ring as energizing element. The seals unique characteristic is caused by the sealing edge profile. Two preceding seal edges act primarily as pressure borderline from both sides and prevent any risk of hydrodynamic pressure which might built-up over the seal profile as well as avoiding the risk of blow-by effects. Central back-up and sealing bulge increase sealing effectivity. Grooves located on both sides plane surfaces are generating in any case the activation of the O-ring energizer. These ensure direct pressure loading of the seal under all operation conditions.

FiPur®-piston seal is an ideal solution for standardizing cylinder construction. It is an efficient and a very cost-effective sealing solution. Cylinders can be adapted meeting different operating conditions. Therefore gap dimension must be checked.

Benefits

  • Excellent static and dynamic sealing effect due to high performance material properties
  • Outstanding abrasion and extrusion resistance
  • Simple groove design, one-piece piston possible
  • Suitable for grooves to ISO 7425
  • Excellent tightness and energy efficiency
  • Simple installation
  • Durability and service life time outstanding due to tribologically optimised TPU-material
  • Full compatibility with mineral oils. Special material grades tailored for environmentally friendly pressure fluids available
