The piston sealing set ZP consists of a one-part rubber-fabric sealing ring and very sturdy "semi-active" back-up rings. The dynamic surface of the seal is reinforced with a special fabric retaining favourably the lubricating film between seal and cylinder wall, even after long standstill periods under high pressure. The breakaway friction and the dynamic friction will be considerably less wear of the seal.

• Exceptionally high static and dynamic sealing performance.
• Enhanced sealing performance in non-pressurized conditions.
• Can also be used for single-acting applications.
• Robust seal profile for harshest operating conditions.
• Insensitive to contamination of the operating medium or slight damage of the sliding surfaces compared with single-part seals.
• Good wear resistance.
• Long service life thanks to application-optimized compounds.
• Constantly low dynamic friction throughout the part's service life.
• Insensitive to extreme pressure peaks.
• Improved lubrication due to pressure medium deposit in the dynamic contact area.
• Extremely high extrusion resistance.
• Simple fabrication of the housing.
• Installation in open housings.
