AS Cryogenic-P
Dry gas seal designed for cryogenic pump applications. Safely seals common industrial liquid gases at extremely low temperatures.
Technical Specifications
- Pressure: ≤7 BarG
- Temperature: Down to -196 °C
- Rotation Speed: Up to 8000 r/min
- Medium: Liquid nitrogen, oxygen, argon, carbon dioxide, LNG
Design Features
- Tungsten Carbide faces provide superior thermal shock resistance for cryogenic temperature cycling.
- Fluorosilicone elastomers maintain flexibility and sealing integrity at extreme sub-zero temperatures.
- Spiral grooves enable gas film operation, eliminating dry-running and face wear in gasifying cryogenic media.
- Inconel 718 spring components resist embrittlement at cryogenic conditions.
