Product Description
Carbon/Silicon Carbide Cartridge Mechanical Seal
Long Life Cartridge Mechanical Seal - Carbon vs Silicon Carbide JG ST70
Engineered for chemical industry applications with exceptional durability and reliability in demanding environments.
Key Features
- Balanced Construction: Maintains seal integrity during sudden pressure changes
- Stationary Spring Design: Springs located in stationary part prevent vibration and O-ring wear from shaft misalignment
- Premium Face Materials: Standard SiC/carbon faces ideal for high-speed applications in condensate and high-pressure pumps
- Cartridge Design: Easy installation with no measurements required, reducing human error
- No Drive Pin Contact: Eliminates face cracking during startup operations
- Material Options: Available in various materials to cover all single seal applications
