Balanced rotary metal bellows seal
In applications where the process fluid is incompatible with common elastomers or where the cost of custom O-Rings is prohibitive, metal bellow mechanical seals are a good option. The Bellows Cartridge Single Seal is designed for these services. This seal enhances reliability by minimizing O-Ring concerns. The Bellows Seal is used primarily in the chemical and petrochemical industries.
The high-strength, low-spring-rate bellows core delivers low-heat generation and reliable sealing performance. The self-cleaning rotary bellows design will reduce the clogging associated with sealing fluids with solids in suspension
Features:
Single Cartridge Seal Design
Innovative Pumping Design
Pressure Resistance Design
