The Type SB2 Heavy-Duty Cartridge Seal features a double-end, balanced design with multiple springs. It also supports independent rotation in either direction. In addition, its stationary spring structure uses pin drive transmission, which supports reliable operation at high speeds.
The springs stay isolated from the process media. Therefore, the design reduces the risk of clogging and sticking. Meanwhile, the piston-type compensation mechanism provides excellent axial compensation. As a result, the seal can accommodate axial movement more effectively during operation.
The Type SB2 uses a cartridge design for easier installation and maintenance. At the same time, its robust construction provides reliable sealing performance in demanding operating conditions.
Key Features
The Type SB2 combines several features for demanding rotating equipment:
- Double-end, balanced design with multiple springs.
- Independent rotation in either direction.
- Stationary springs with pin drive transmission.
- Isolated springs to reduce clogging and sticking.
- Cartridge construction for easier installation.
Applications
The Type SB2 mechanical seal mainly serves paper pulp pumps and flue gas desulfurization (FGD) systems. It also suits condensate pumps, filters, pressure screens, and other rotating equipment.
- Pulp and paper production
- Chemical processing
- Filtration systems
- Wastewater treatment
- Flue gas desulfurization systems
Safematic Replacement Seal
The Type SB2 serves as a Safematic replacement seal for compatible equipment. It can also work with an ANDRITZ Safematic seal support system when the seal dimensions, materials, and operating conditions match the original application.Therefore, the Type SB2 offers a practical replacement option for paper pulp, FGD, filtration, and other demanding industrial applications.
