- DESCRIPTION
SB is single acting buffer sealing element which consists of two parts: sealing element of special profile and and one thermoplastic back-up ring. The seal is designed for to evacuatethe back pressure and prevent it from being squeezed into the gap when pressure peaks occur. It is used exclusively in combination with a secondary seal (eg. MP; MP/L).
- ADVANTAGES
• Smoothing out the peak pressure at the secondary seal and maintaining a constant operating pressure
• No overpressure between primary and secondary seals
• High wear resistance
• Support ring prevents extrusion into the gap
• Easy installation- MATERIAL
