Metal Bellow Single Acting Seal
Welded metal bellow seal for high-temperature service.
Series IPSM 727 is a welded metal bellow seal for high-temperature and moderate-pressure applications in petrochemical plants, petroleum refineries, edible-oil refineries and similar plants.
The welded metal bellow replaces both the spring and the dynamic elastomer, so there is no elastomer to harden or char at high temperature and no spring to clog.
IPSM 727 is the standard choice for hot heat-transfer oil, hydrocarbon and edible-oil duties beyond the range of elastomer seals.
Key features
- Welded metal bellow - no spring, no dynamic elastomer
- High-temperature capability to +400 °C
