AS 2800E-P
Pump-specific variant of the 2800E dry gas seal. Pressurized dual cartridge design with spiral-grooved rotating face for non-contacting gas film operation.
Technical Specifications
- Pressure: ≤2.5 MPa
- Temperature: -20 to 150 °C
- Rotation Speed: Up to 3600 r/min
- Medium: Sedatives, reactants, process gases
Design Features
- Dual-balanced structure equivalent to John Crane 2800E, ensuring no leakage during seal gas failure.
- Compact axial dimensions suitable for centrifugal pumps with short sealing chamber lengths.
- Simple auxiliary system — uses nitrogen or process gas at 0.15–0.2 MPa above medium pressure.
