The BU rod seal is a compact seal with an integrated anti-extrusion ring. It is frequently used as a buffer seal within sealing systems such as those utilized in construction machine cylinders. Construction machine cylinders operate in harsh conditions in which pressure peaks of up to 1000 bar frequently occur. The BU rod seal is installed upstream to isolate such loads from the secondary seal. Due to its special shape, the seal (like a return valve) is able to return pressure that may build up between the primary and the secondary seal into the system. A single or tandem arrangement of this product series is possible as well.
• Enhanced sealing performance in non-pressurized conditions.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Insensitive to extreme pressure peaks.
• Extremely high extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
Scope of application:
Pressure: ≤500 bar
Operating temperature: -35°C to +100°C
Surface speed: 0.5 m/s
Medium: mineral-based hydraulic oils, emulsions
Material: PU93 Shore. Compared with other polyurethane materials currently sold in the market, its main advantages include improved heat resistance, enhanced hydrolysis resistance, and small compression deformation.
