Construction
| Bellows: | AM350, Inconel 718, Haste Alloy C-276 |
| Secondary Seal: | Grafoil, O-ring |
| Seal Face: | Metallic Carbon, SIC, SSIC(alpha), Tungsten graphite |
| face holder | 17-4ph, Carpenter-42, Alloy-20, Duplex |
| Adaptor/Dry collar: | SS 316L, Alloy 20, Inconel 718, Duplex |
A metal bellow seal designed specifically for vacuum pump service. It uses welded metal bellows to accommodate shaft movement and temperature/pressure changes while maintaining a tight seal against vacuum and low-pressure environments.
Ideal for pumps used in vacuum applications where leakage is not acceptable, and reliability under pressure differential is critical.

Operating
| Temperatures: | upto 400° : AM350 |
| Above 400°: Haste Alloy C-276 & INCONEL-718 | |
| Pressure: | Under 10kg/Up to 9.8bar: Single Ply |
| Above 10kg/Up to 29.4bar: Double Ply | |
| Speed: | Up to 5000 rpm or 25 m/s |
* These operating limits are non-concurrent. In general, an incease in the seal size, or temperature, or rotating speed can reduce the maximum operating pressure limit of the metal bellow component.
