General characteristics
Double seal, compact design, balanced, independent from the direction of rotation, multi-spring. The seal requires application of buffer or barrier liquid installation.
Range of sizes available
- Shaft diameter: d = 22 ... 100 mm
Operating parameters
- Pressure: < 1.6 MPa
- Temperature: < 200 °C
- Velocity: < 12.5 m/s
Applications
The BED is a general purpose mechanical seal with a wide range of applications. It is designed to work with media containing abrasive particles (e.g., ash, ores, cement, sludge and suspended matter) and chemicals harmful to the environment.
BED seal requires installation of a system of buffer liquid (acc. to API Plan 52, 55) or barrier liquid (API Plan 53a, 53b, 53c, 54). Maximum pressure of barrier liquid: 2.0 MPa.
